Microsoft Windows

Microsoft Windows is a series of software operating systems and graphical user interfaces produced by Microsoft. Microsoft first introduced an operating environment named Windows on November 20, 1985 as an add-on to MS-DOS in response to the growing interest in graphical user interfaces. Microsoft Windows came to dominate the world's personal computer market, overtaking Mac OS, which had been introduced in 1984. As of October 2009, Windows had approximately 91% of the market share of the client operating systems for usage on the Internet. The most recent client version of Windows is Windows 7; the most recent server version is Windows Server 2008 R2; the most recent mobile OS version is Windows Phone 7.

Basic concept of operating system and functionComputer SystemsA computer system consists of two basic types of components:

Hardware components, which are the electronic devices and electromechanical devices, such as the processors, memory modules, disk units, keyboard, screen, and other devices. Software components, such as the application programs, operating system, utilities, and other programs.Computer Architecture

The architecture of a computer system is the relationship among the various components. Computer systems have the following three fundamental functions: processing, input, and output.

Structure of a Computer SystemThe basic structure of a computer normally consists of one or more of the following hardware components:

The CPU or the central processing unit, also called the processor RAM or random access memory, also known as main memory The massive storage devices, which store large amounts of data and programs in permanent form The I/O devices or input/output units The system bus, which provides interconnections for all components of the system

Computer Network On a local area network (LAN), several small computers are connected to a larger computer called a server, and depending on the network topology, the smaller computers may also be connected to each other.

The server stores the global files or databases and may include one or more shared printers. A much larger type of network is known as a wide area network (WAN) and covers a large geographical region and connects local area networks located in various remote places. Hardware Interrupts An interrupt mechanism in which a hardware component (an I/O device) sends an interrupt request signal to the CPU. This interrupt signal causes a temporary stop of the normal execution of a program, and the CPU then starts to execute a special function called an interrupt service routine (ISR) that handles the interrupt. When the execution of this routine is complete, the CPU can resume the execution of the program that was interrupted.Interrupts An application requests an operating system to perform an operation by using a Software Interrupt. Interrupts are requests to the operating system to do something. An operating system is interrupt drivenSoftware A program is a sequence of instructions to be executed in the computer for the purpose of carrying out some specific task. Before a program executes, it has to be translated from its original text form (source program) into a machine language program. Then, the program needs to be linked and loaded into memory.

Software Components The software components are the collection of programs that execute in the computer. These programs perform computations, control, manage, and carry out other important tasks. Two general types of software components are: System software, Application software

System Software The system software is the set of programs that control the activities and functions of the various hardware components, programming tools and abstractions, and other utilities to monitor the state of the computer system. The system software forms an environment for the programmers to develop and execute their programs (collectively known as application software). Three types of users can be identified: System programmers, Application programmers and end-users.

Application Software Application software consists of those programs that solve specific problems for the users and execute under control of the operating system. Application programs are developed by individuals and organizations for solving specific problems.

Types of Software Systems System software-Operating System, Assemblers, Loaders, Linkers, Compilers, Editors.. Application software-All User-Oriented Programs. Application program System program Hardware userWhat is an Operating System? A large and complex software component for the operation and control of the computer system. It acts as an intermediary between a user and the computer system. Examples: Unix, MS Windows, Mac-OS, Linux, Sun Solaris, DEC VMS, etc.

Introduction of window using mouse

The windows operating system started with the introduction of Windows OS and Windows for work group for networking. Since then it has come a long way and Windows 95, 98 and 2000 family of operating systems were introduced. It provided the computer user with the most integrated and easy to use operating system with all the facilities in built. The Windows XP is the newborn baby in the Windows family. It is built on the windows 2000 concept and framework. It has more features to provide the user with greater stability, security and enhanced performance.

Using your mouseJust as you would use your hands to interact with objects in the physical world, you can use your mouse to interact with items on your computer screen. You can move objects, open them, change them, throw them away, and perform other actions, all by pointing and clicking with your mouse.

Basic partsA mouse typically has two buttons: a primary button (usually the left button) and a secondary button (usually the right button). The primary button is the one you will use most often. Most mice also include a scroll wheel between the buttons to help you scroll through documents and web pages more easily. On some mice, the scroll wheel can be pressed to act as a third button. Advanced mice might have additional buttons that can perform other functions.

Holding and moving the mousePlace your mouse beside your keyboard on a clean, smooth surface, such as a mouse pad. Hold the mouse gently with your index finger resting on the primary button and your thumb resting on the side. To move the mouse, slide it slowly in any direction. Don't twist itkeep the front of the mouse aimed away from you. As you move the mouse, a pointer (see picture) on your screen moves in the same direction. If you run out of room to move your mouse on your desk or mouse pad, just pick up the mouse and bring it back closer to you.

Pointing, clicking, and draggingPointing to an item on the screen means moving your mouse so the pointer appears to be touching the item. When you point to something, a small box often appears that describes the item. For example, when you point to the Recycle Bin on the desktop, a box appears with this information: "Contains the files and folders that you have deleted."The pointer can change depending on what you're pointing to. For example, when you point to a link in your web browser, the pointer changes from an arrow to a hand with a pointing finger .Most mouse actions combine pointing with pressing one of the mouse buttons. There are four basic ways to use your mouse buttons: clicking, double-clicking, right-clicking, and dragging.Clicking (single-clicking)To click an item, point to the item on the screen, and then press and release the primary button (usually the left button).Clicking is most often used to select (mark) an item or open a menu. This is sometimes called single-clicking or left-clicking.Double-clickingTo double-click an item, point to the item on the screen, and then click twice quickly. If the two clicks are spaced too far apart, they might be interpreted as two individual clicks rather than as one double-click.Double-clicking is most often used to open items on your desktop. For example, you can start a program or open a folder by double-clicking its icon on the desktop.Right-clickingTo right-click an item, point to the item on the screen, and then press and release the secondary button (usually the right button).Right-clicking an item usually displays a list of things you can do with the item. For example, when you right-click the Recycle Bin on your desktop, Windows displays a menu allowing you to open it, empty it, delete it, or see its properties. If you're ever unsure of what to do with something, right-click it.

DraggingYou can move items around your screen by dragging them. To drag an object, point to the object on the screen, press and hold the primary button, move the object to a new location, and then release the primary button.Dragging (sometimes called dragging and dropping) is most often used to move files and folders to a different location and to move windows and icons around on your screen.Using the scroll wheelIf your mouse has a scroll wheel, you can use it to scroll through documents and webpages. To scroll down, roll the wheel backward (toward you). To scroll up, roll the wheel forward (away from you).

Customizing your mouseYou can change your mouse settings to suit your personal preferences. For example, you can change how fast your mouse pointer moves around the screen, or change the pointer's appearance. If you're left-handed, you can switch the primary button to be the right button. Tips for using your mouse safelyHolding and moving your mouse properly can help you avoid soreness or injury to your wrists, hands, and arms, particularly if you use your computer for long periods of time. Here are some tips to help you avoid problems: Place your mouse at elbow level. Your upper arms should fall relaxed at your sides. Don't squeeze or grip your mouse tightly. Hold it lightly. Move the mouse by pivoting your arm at your elbow. Avoid bending your wrist up, down, or to the sides. Use a light touch when clicking a mouse button. Keep your fingers relaxed. Don't allow them to hover just above the buttons. Basic Component of Windows

M.S Office

Microsoft Office is a proprietary commercial office suite of inter-related desktop applications, servers and services for the Microsoft Windows and Mac OS X operating systems, introduced by Microsoft in 1989. Initially a marketing term for a bundled set of applications, the first version of Office contained Microsoft Word, Microsoft Excel, and Microsoft PowerPoint. Over the years, Office applications have grown substantially closer with shared features such as a common spell checker, OLE data integration and Microsoft Visual Basic for Applications scripting language. Microsoft also positions Office as a development platform for line-of-business software under the Office Business Applications brand. According to Forrester Research, as of June 2009, some version of Microsoft Office is used in 80% of enterprises, with 64% of enterprises using Office 2007. The current versions are Office 2010 for Windows, released on June 15, 2010; and Office 2011 for Mac OS X, released October 26, 2010.

Microsoft WordMicrosoft Word is a word processor and was previously considered to be the main program in Office. It is commonly known, is a software application that allows you (the user) to perform word processing. You may use Word to create documents such as letters, invitations, term papers, flyers, resumes, novels, and much more!Last Its proprietary DOC format is considered a de facto standard, although Word 2007 can also use a new XML-based, Microsoft Office-optimized format called. DOCX which has been standardized by Ecma International as Office Open XML and its SP2 update will support ODF and PDF. Word is also available in some editions of Microsoft Works. It is available for the Windows and Mac platforms. The first version of Word, released in the autumn of 1983, was for the MS-DOS operating system and had the distinction of introducing the mouse to a broad population. Word 1.0 could be purchased with a bundled mouse, though none was required. Following the precedents of Lisa Write and MacWrite, Word for Macintosh attempted to add closer WYSIWYG features into its package. Word for Mac was released in 1985. Word for Mac was the first graphical version of Microsoft Word. Despite its business, It became one of the most popular Mac applications.

Microsoft Excel

Microsoft Excel is a spreadsheet program which originally competed with the dominant Lotus 1-2-3, but eventually outsold it. It is available for the Windows and Mac platforms. Microsoft released the first version of Excel for the Mac in 1985, and the first Windows version (numbered 2.05 to line up with the Mac and bundled with a standalone Windows run-time environment) in November 1987.

What is Excel: Excel is an Electronic Spreadsheet ProgramExcel is an electronicspreadsheetprogram that can be used for storing, organizing and manipulatingdata.When you look at the Excel screen (refer to the example) you see a rectangular table or grid ofrowsandcolumns. The horizontal rows are identified by numbers (1,2,3) and the vertical columns with letters of the alphabet (A,B,C). For columns beyond 26, columns are identified by two or more letters such as AA, AB, AC.The intersection point between a column and a row is a small rectangular box known as a cell. A cell is the basic unit for storing data in the spreadsheet. Because an Excel spreadsheet contains thousands of these cells, each is given acell referenceor address to identify it.

The cell reference is a combination of the column letter and the row number such as A3, B6, AA345.Data Types, Formulas, and FunctionsThe types of data that a cell can hold include numbers, text or formulas. Just as in math class,formulasare used for calculations usually involving data contained in other cells. Excel and other electronic spreadsheets include a number of built in formulas used for common tasks known asfunctions.Excel and Financial DataSpreadsheets are often used to store financial data. Formulas and functions that are used on this type of data include: Performing basic mathematical operations such as summing columns and rows of figures. Finding values such as profit or loss. Calculating repayment plans for loans or mortgages. Finding the average, maximum, or minimum values in a specified range of data.Excel's Other UsesOther common operations that Excel can be used for include: graphing orchartingdata to assist users in identifying data trends. sorting and filtering data to find specific information.The information garnered in a spreadsheet can easily be incorporated into electronic presentations, web pages, or printed off in report form.

Microsoft Power PointMicrosoft PowerPoint is a full-featured desktop presentation program. It is part of theOffice suite and can be purchased separately. A presentation can be a collection of slidesrelating to a specific topic, which may be shown while the topic is discussed or may beshown as a continuous show. From the presentation slides, handouts, speaker notes, oroutlines can also be prepared. PowerPoint contains graphic tools and many kinds ofpictures and graphs to be imported. A Macintosh version is available which functionsalmost identically to the Windows version. Presentations created in either platform can be run from the other, without any conversion needed.

Unit-2INTEGRATION OF ICT WITH SCHOOL TEACHING SUBJECTSMaking SMALL PresentationSPOINTS TO REMEMBER WHILE MAKING A PRESENTATION Have a very clear introduction, to motivate what you do and to present the problem you want to solve. The introduction is not technical in nature, but strategic (i.e. why this problem, big idea). If you have a companion paper, mention it during the talk and recommend it for more details. Don't put all the details in the talk. Present only the important ones. Use only one idea per slide. Have a good conclusions slide: put there the main ideas, the ones you really want people to remember. Use only one "conclusions" slide. The conclusion slide should be the last one. Do not put other slides after conclusions, as this will weaken their impact. Having periodic "talk outline" slides (to show where you are in the talk) helps, especially for longer talks. At least one "talk outline" slide is very useful, usually after the introduction. Don't count on the audience to remember any detail from one slide to another (like color-coding, applications you measure, etc.). If you need it remembered, re-state the information a second time. Especially if you have to present many different things, try to build a unifying thread. The talk should be sequential in nature (i.e. no big conceptual leaps from one slide to the next). Try to cut out as much as possible; less is better. Help the audience understand where you are going. Often it's best to give them a high-level overview first, and then plunge into the details; then, while listening to the details they can relate to the high-level picture and understand where you are. This also helps them save important brain power for later parts of the talk which may be more important. Use a good presentation-building tool, like MS PowerPoint. Avoid Latex, except for slides with formulas. Humor is very useful; prepare a couple of puns and jokes beforehand (but not epic jokes, which require complicated setup). However, if you're not good with jokes, better avoid them altogether. Improvising humor is very dangerous. The more you rehearse the talk, the better it will be. A rehearsal is most useful when carried out loud. 5 rehearsals is a minimum for an important talk. The more people criticize your talk (during practice), the better it will be; pay attention to criticism, not necessarily to all suggestions, but try to see what and why people misunderstood your ideas. Not everything has to be written down; speech can and should complement the information on the slides. Be enthusiastic. Act your talk: explain, ask rhetorical questions, act surprised, etc. Give people time to think about the important facts by slowing down, or even stopping for a moment. Do not go overtime under any circumstance. Listen to the questions very carefully; many speakers answer different questions than the ones asked. Do not treat your audience as mentally-impaired: do not explain the completely obvious things.

Text Slides should have short titles. A long title shows something is wrong. Use uniform capitalization rules. All the text on one slide should have the same structure (e.g. complete phrases, idea only, etc.). Put very little text on a slide; avoid text completely if you can. Put no more than one idea per slide (i.e. all bullets should refer to the same thing). If you have lots of text, people will read it faster than you talk, and will not pay attention to what you say. Don't use small fonts. Use very few formulas (one per presentation). The same goes for program code (at most one code fragment per presentation). Do not put useless graphics on each slide: logos, grids, affiliations, etc. Spell-check. A spelling mistake is an attention magnet.

Creation of presentation

Making slides in Powerpoint

Set your slides up as 35 mmPower Point automatically defaults to On-screen show for any new presentation. This setting will not give the correct aspect ratio for the slide, and will result in black lines on either side of your slide. To avoid this your presentation needs to be set to 35mm Slides for the presentation to be imaged correctly. It is best to do this before any slide layout and design is done, as the conversion from On-screen show to 35mm Slides can dramatically affect tabbing, text layout, and precision layout of arrows and indicators. Any presentations we receive as On-screen show cannot be guaranteed to look as intended, and may have to be sent back to the client for corrections.The following screen shots outline the process of changing the page set-up.

Figure 1a. Select File/Page Set-upFigure 1b. Using the pull down menu, change the Page Set-upto 35mm Slides.

Note: If you use the Auto Content Wizard to set-up your slides, you will be asked What kind of output will you use?, and you should answer 35mm slides. If you have a custom template set-up as 35mm, then you dont need to worry, as 35mm will be set automatically.Note: If you need a set of slides as well as a presentation using a computer data projector, then your best choice is to set up your slide as 35mm, as this will still work fine with the data projector and you only need one file.

Use the Master Slide to define your slideWith a presentation open, go to View/Master/Slide Master (Figure 2a). You will now see the slide master. Any settings you make now, such as font, font size, font color, bullet colour, text placeholder position etc. will apply to all new slides.

To add a logo to all the slides in the presentation, import a picture and position it. It will appear on all slides automatically. Likewise, a new text box with a department or company name on the master, will appear on all slides in the presentation.

Your settings will apply to all slide layouts except the title slide layout, which has its own master, and surprise, its called the Title Master.

Once you are happy with the way you have defined your masters, you should save your presentation as atemplate for future use. (Again, ensuring that the slide is set up as 35mm).

Figure 2a. Go to the Slide Master View.

Figure 2b. The Slide Master

Note: The Master slides will only control text which is contained within a placeholder. Any additional text boxes that are added to an individual slide will not be controlled by the masters.Note: To get back to a normal slide after defining your master, go to View/Slide.

Use a template set-up as 35mmIf you do a lot of presentations, and you want to keep the same look so you can mix and match presentations, then you can use a template to record settings such as slide set-up, colors, fonts etc. After using the slide master to define properties such as fonts, bullets, text position, text formatting, background, text color, logo etc. (with the slide set-up as 35mm), you can save your blank presentation as a template. When you need to do a new presentation, you simply open your template, and all of your settings are preserved.

To make a template, ensure the presentation has all the above properties set as desired (via the Master Slide), go to the Slide Sorter view (View/Slide Sorter), delete all slides, return to "Slides" view (View/Slides), then save the presentation as a Presentation Template.Figure 3. If you save your template in Presentation Designs, as above, when you make a new presentation using a template, it will appear as below, with all of the default templates. Rather handy.

ColoursBe careful with the use of colour. A good guide is to use a deep blue or green background colour, with white, yellow, orange and cyan text and lines. White is dominant therefore it is good for highlighting text. Due to the sensitivity of our eye, yellow letters will appear to come forward; dark blues and deep reds will recede, so yellow on blue, for instance, will make a slide that is easy to read.Avoid red text, especially on a blue or green background, as it is very hard on the eyes, and often impossible for your audience to read. In fact there will most likely be a portion of your audience who is colour-blind.Never use blue letters on a black background or black letters on blue as our eyes are not very sensitive to blue and there is not enough contrast between these colours to make these combinations easy to read.Don't be tempted to go crazy with color: Just because you can use 27 different color combinations on a single slide doesnt mean you have to!!!!If you dont want to go with the tried and true white & yellow on blue slides, then a good starting point is to have a look at the templates supplied with powerpoint, as most of the colour schemes work well when projected.

BackgroundsBackgrounds often look good if they are graduated for example, from blue, to darker blue, but avoid using a graduation of two colors for a background.Darker backgrounds with lighter text tend to be easier to read than light backgrounds with dark or black text, especially in a darkened room, as is usually the case when projecting slides.Whatever you choose, keep the same background throughout the presentation. for a consistent presentation. Consider using a small logo on the background throughout your presentation.

Keep it simpleDont try to fit a whole novel on each slide. Bullets and short phrases are more effective than sentences. If you can shorten a point, then do so. A good guide is to use no more than 5-7 bullets per slide, and no more than 5-7 words per bullet.Try holding a slide at reading distance to see if you can read it or go to View/Slide Show, move back about 5 feet from your monitor (for a 15 inch, more for larger monitors), and try to read your slide from here. This will give you a good representation of what the audience will see.One concept/slide at a time is a good guide; or use progressive disclosure slides (using animation) where the audience only sees the point you are about to talk about.Word slides should be used to outline and emphasize key words.Ask yourself whether you can scan the information on the slide in 15 seconds because this is what your audience will do.Try to change slides every 30 -60 seconds to give a good pace to your talk and keep your audience interested.The use of graphs or graphics can add interest as well as simplify the information.Above all slides should support you and reinforce the message you are conveying.Dont be tempted to go right to the edge of the slide. Apart from looking over crowded, you will not get everything you see on the slide.The slide mount is smaller than the image area. Rule of thumb - keep all objects a mouse pointer (approx. 3/8 inch) away from the edge of the slide.

Dont use Excel for your graphs !!!Graphs are a great way to present a great deal of information to your audience. It is much easier to view a graph than digest a series of numbers in a table.

But dont do your graphs in Excel and then import them into Powerpoint. Excel is used for number crunching by accountants etc, not by people trying to make a cutting edge presentation: thats what Powerpoint is for.Powerpoint has a fantastic graphing program all of its own, and the graphs it produces are more pleasing to the eye, behave better, and fit into the look of your presentation. The graphing program built into PowerPoint is very similar to the one in Excel, but it simply works better. Even if you are producing a graph for a journal or other publication, use PowerPoint.There may be occasions where you need to use the power of Excel to extrapolate data or statistics to obtain a result. The you simply copy the data from an Excel workbook, and paste it into the data sheet in PowerPoints graphing program. The latest version of Powerpoint will even do graphs with error bars.

Introduction to MultimediaMultimedia can have a many definitions these include: Multimedia means that computer information can be represented through audio, video, and animation in addition to traditional media (i.e., text, graphics/drawings, images).General DefinitionA good general working definition for this module is: Multimedia is the field concerned with the computer controlled integration of text, graphics, drawings, still and moving images (Video), animation, audio, and any other media where every type of information can be represented, stored, transmitted and processed digitally.Multimedia Application DefinitionA Multimedia Application is an application which uses a collection of multiple media sources e.g. text, graphics, images, sound/audio, animation and/or video.What is HyperText and HyperMedia?Hypertext is a text which contains links to other texts. The term was invented by Ted Nelson around 1965.Hyper Text NavigationTraversal through pages of hypertext is therefore usuallynon-linear (as indicated below).This has implications in layout and organisation of material and depends a lot on the application at hand.Hypermedia Hyper Media is not constrained to be text-based. It can include other media, e.g., graphics, images, and especially the continuous media sound and video.

Example Hypermedia Applications?The World Wide Web (WWW) is the best example of a Hypermedia application. PowerPoint. Adobe Acrobat Many Others?

Multimedia Applications

Examples of Multimedia Applications include: World Wide Web Multimedia Authoring, e.g. Adobe/Macromedia Director Hypermedia courseware Video-on-demand Interactive TV Computer Games Virtual reality Digital video editing and production systems Multimedia Database systems

Multimedia SystemsA Multimedia System is a system capable of processing multimedia data and applications. A Multimedia System is characterized by the processing, storage, generation, manipulation and rendition of Multimedia information.

Characteristics of a Multimedia SystemA Multimedia system has four basic characteristics: Multimedia systems must be computer controlled. Multimedia systems are integrated. The information they handle must be represented digitally. The interface to the final presentation of media is usually interactive.

Challenges for Multimedia SystemsDistributed NetworksTemporal relationship between dataRender different data at same time continuously.Sequencing within the media

Playing frames in correct order/time frame in video Synchronization inter-media scheduling E.g. Video and Audio Lip synchronization is clearly important for humans to watch playback of video and audio and even animation and audio. Ever tried watching an out of (lip) sync film for a long time?

Key Issues for Multimedia Systems The key issues multimedia systems need to deal with here are: How to represent and store temporal information. How to strictly maintain the temporal relationships on play back/retrieval What process are involved in the above. Data has to represented digitally AnalogDigital Conversion, Sampling etc. Large Data Requirements bandwidth, storage,

Data compression is usually mandatoryDesirable Features for a Multimedia System

Given the above challenges the following feature a desirable(if not a prerequisite) for a Multimedia System:Very High Processing Power needed to deal with large data processing and real time delivery of media.Special hardware commonplace.Multimedia Capable File System needed to deliver real-time media e.g. Video/Audio Streaming. Special Hardware/Software needed e.g. RAID technology.Data Representations File Formats that support multimedia should be easy to handle yet allow for compression/decompression in real-time.Efficient and High I/O input and output to the file subsystem needs to be efficient and fast. Needs to allow for real-time recording as well as playback of data.e.g. Direct to Disk recording systems.Special Operating System to allow access to file system and process data efficiently and quickly. Needs to support direct transfers to disk, real-time scheduling, fast interrupt processing, I/O streaming etc.Storage and Memory large storage units (of the order of hundreds of Tb if not more) and large memory (several Gbor more). Large Caches also required and high speed buses for efficient management.Network Support Client-server systems common as distributed systems common.Software Tools user friendly tools needed to handle media, design and develop applications, deliver media.

Components of a Multimedia SystemNow let us consider the Components (Hardware and Software) required for a multimedia system:Capture devices Video Camera, Video Recorder, Audio Microphone, Keyboards, mice, graphics tablets, 3D input devices, tactile sensors, VR devices. Digitizing Hardware.Storage Devices Hard disks, CD-ROMs, DVD-ROM, etcCommunication Networks Local Networks, Intranets, Internet, Multimedia or other special high speed networks.Computer Systems Multimedia Desktop machines, Workstations, MPEG/VIDEO/DSP HardwareDisplay Devices CD-quality speakers, HDTV,SVGA, Hi-Res monitors, Colour printers etc.

A Brief Look at Multimedia Data:Input and FormatText and Static Data Source: keyboard, speech input, optical character recognition, data stored on disk. Stored and input character by character: Storage of text is 1 byte per character (text or format character). For other forms of data (e.g. Spreadsheet files). May store format as text (with formatting) others may use binary encoding. Format: Raw text or formatted text e.g HTML, Rich Text Format (RTF), Word or a program language source (C, Pascal, etc.. Not temporal BUT may have natural implied sequence e.g. HTML format sequence, Sequence of C program statements. Size Not significant w.r.t. other Multimedia data.

Graphics Format: constructed by the composition of primitive objects such as lines, polygons, circles, curves and arcs. Input: Graphics are usually generated by a graphics editor program (e.g. Illustrator) or automatically by a program (e.g.Postscript). Graphics are usually editable or revisable (unlike Images). Graphics input devices: keyboard (for text and cursor control), mouse, trackball or graphics tablet. graphics standards : OpenGL, PHIGS, GKS Graphics files usually store the primitive assembly Do not take up a very high storage overhead.

Images Still pictures which (uncompressed) are represented as a bitmap (a grid of pixels). Input: digitally scanned photographs/pictures or direct from a digital camera. Input: May also be generated by programs similar to graphics or animation programs. Stored at 1 bit per pixel (Black and White), 8 Bits per pixel (Grey Scale, Colour Map) or 24 Bits per pixel (True Colour) Size: a 512x512 Grey scale image takes up 1/4 Mb, a 512x512 24 bit image takes 3/4 Mb with no compression. This overhead soon increases with image size modern high digital camera 10+ Megapixels _ 29Mb uncompressed! Compression is commonly applied.

Audio Audio signals are continuous analog signals. Input: microphones and then digitized and stored CD Quality Audio requires 16-bit sampling at 44.1 KHz Even higher audiophile rates (e.g. 24-bit, 96 KHz) 1 Minute of Mono CD quality (uncompressed) audio requires 5 Mb. 1 Minute of Stereo CD quality (uncompressed) audio requires 10 Mb. Usually compressed (E.g. MP3, AAC, Flac, Ogg Vorbis).

Video Input: Analog Video is usually captured by a video camera and then digitized. There are a variety of video (analog and digital) formats Raw video can be regarded as being a series of single images. There are typically 25, 30 or 50 frames per second. E.g. A 512 _ 512 size monochrome video images take 25 0:25 = 6.25Mb for a minute to store uncompressed. Typical PAL digital video (720 _ 576 pixels per colour frame) 1:2 _ 25 = 30Mb for a minute to store uncompressed. High Definition DVD (1440_1080 = 1.5 Megapixels per frame) 4:5 _ 25 = 112.5Mb for a minute to store uncompressed. (There are higher possible frame rates!) Digital video clearly needs to be compressed for most times.
