LETS Start!!!!!!!!!!!!!!!!!!!!!!!!!

Let enlist our objectives

• Understanding/sharing the basics of ICT

• Exploring the role/importance of ICT in society

• Explanation and examples of ICT

• ICT in Learning and Teaching

• Description of history and developments of Computer

• Distinguish different generations

• Classification of computers

• General terms/parts of computer

Have you ever used ICT?

• Have you not made a call ever on Cell phone?

• Have you not send an IM using your Cell phone?

• Have you not used Internet/email before?

• Have you not listend Radio ever?

• Have you net watched TV ever?

• Have you never used any computer ever?

• Yes, Of course everyone of you do it daily, I am sure.

• This is all about ICT…………

ICT introduction

• Information: referred as processed form of data which can be recorded, organized and transmitted.

• Communication: Transfer of ideas(data & information) though systems, devices such as computer, cell phones, internet, TV etc.

• Technology: the way one make, modify and use tools, techniques, systems and machines to solve problems efficiently.

Basic concepts of ICT

• Comprises of different communication devices

• Continuously evolving products and services• Manufacturing of ICT- Equipment• Variety of services like Software development

and Apps• Global Village : easy communication and

sharing of ideas• Refers to those technologies that provide access

to information by means of telecom.

Major mediums of ICT (Application)

• Internet and Computer▫ Web, email, video conference, Social media▫ Converting seminar into webinars, universities

into Virtual universities▫ online education, e-business, e leaning, e

commerce

• Cell phones▫ Calling, IM, communication, games,

entertainment▫ Mobile Apps

Examples of ICT application

• FB groups for communication and sharing• Whatsapp Groups for quick and multimedia

messaging• Skype for calling and online lectures and

education by group calls• Teamviewer for remote access • YouTube for gigantic source of information in

video format• Mobile apps and software for routine tasks like

word processing, spreadsheet, and presentations

ICT in Teaching and Learning

• Lets try to enlist the benefits of using ICT in teaching and learning….

• Do you agree that we can teach well?

• Do you agree that students can learn well?

• Do you thing one can present well?

• Do you agree one can work efficiently?

• Then why?

• We why we hesitate to use it?

ICT in Teaching and Learning

• Provide new and easy of learning and generating new ideas. (growing age at school)▫ The late Arfa Karim (youngest MCP)▫ Muhammad Ammar Afzal From Okara (highest socre

in ORACLE)▫ Sumal Hassan form Karachi: 3rd highest earning

eSports professional with total earnings of$2,401,426.34 .

• Multimedia and other ICT facilities may help teachers in classroom

• eTesing software can reduce the burden of teachers• ICT can create effective learning environment

Any question about ICT and teaching and learning via ICT

Lets start again with a puzzle

• Guess what machine we are going to find?

• Few tips about that are

• "Giant Brain"

• cost was about $487,000, equivalent to $6,740,000 in 2016

• It weighed more than 30 tons

• Size was (8 × 3 × 100 feet) in size, occupied 167 m2 (1,800 ft2)

• It consumed 150 kW of electricity.

Lets start again with a puzzle: An

Earliest Computer

History and development of

Computer• The base rule is same “necessity is the mother of

invention”• Abacus Machine• Napier’s bones• Blaise Pascal (Pascline- 8 digit)• Charles Babbage

▫ Difference engine▫ Analytical engine

• IBM, ENIAC, EDSAC etc mechanical, electro-mechanical and electrical/digital

Generation of Computers

• A step in computer technology is called generation.

• Development of computers are divided into five periods called generations

• First

• Second

• Third

• Fourth

• Fifth

Generations of computerGene Period Technology Features Limitations

First 1951-58 Vacuum tube First electrical Punch card inputMachine language

Spacious, heat generated and huge energy consumption

Second 1959-64 Transistor Punch card inputMagnetic tape storageHigh level languageReliable, speedy, less heat and less space

AC was requiredComplex production of Transistors

Third 1965-70 Integratedcircuit (IC)—1000s of transistors

Keyboard inputMonitor displayHigh level languageReliable, speedy, less size and cheaper

Still IC tech was complex and immature, AC was required

Generations of computerGene Period Technology Features Limitations

Fourth 1980 Microprocessors VLSIULSIMillions of transistors in single chip

Keyboard inputMonitor displayHigh level languageCommercial useCheaperNo AC required

No senses

Fifth Late 1990s

Artificial intelligence…Thinking, feeling and reasoningpower.

Voice recognitionImage processingOptical fibercommunicationPROLOG is language

Generations of computer- Fifth

Generation examples (AI)

• Lets try to collect examples from our daily life..

• Robotics

• Mobile sensors

• Sensors used in sanitary items

• Thermostatic used in Refrigerators.

• Gluco-meter

• ICU – monitors

• Modern daily life gadgets.

• Expert systems….

Classification of Computers

• On the basis of size, memory and processing power computers are classified into two major categories

• Size

▫ Super computers

▫ Mainframe computers

▫ Mini computers

▫ Micro computers

▫ Handheld computers

▫ Laptops

▫ Palmtop and PDA

Classification of Computers

• Purpose• Digital computers

▫ General purpose▫ Digits and characters ▫ Examples are PC, laptop etc

• Analog computers▫ Special purpose▫ Continuous type of data rather than digits▫ Measuring temp, wheel balancing, speedometer

• Hybrid computers▫ Both digital and analog ▫ Digital sugar checking device, DSL modems

Applications of computers

• It is useful in every aspect of life

• Education ( CAL, CBT, e-learning)

• Business (ERP, Info. system, e commerce, )

• Banking (ATM, online banking, m banking)

• Defense (GPS, missiles, nuclear weapons etc)

• Entertainment ( movies, games, music, 3D/HD)

• Health (ICU monitors, HMS)

• Agriculture ( drone monitoring, drone spraying tools, modern agri machinery)

General terms

• Buses : electrical paths though which data and instructions are transferred (32 bit, 64 bit)

▫ Control bus

▫ Data bus

▫ Address bus

• Computer ports

▫ Serial port

▫ Parallel port

▫ Universal serial bus (USB)

General terms

• Buses : electrical paths though which data and instructions are transferred

• Memory▫ Primary

RAM DRAM (Dynamic RAM) (refreshed every few

milliseconds) (slow) SRAM (Static RAM) fast, used as cache, in smart devices ROM

▫ Secondary memory Magnetic tape Hard disk Optical disk (CD, DVD, Blue Ray)

CPU (central processing unit)

• Commonly knows as processor…booknamemicroprocessor

• Brain of computer

• Intel, Motorola

• Arithmetic and logical unit

• Control unit

• Modern age processor

• Bus interface unit, floating point units, multi cores processor

What we try to learn today?

• What is ICT

• Use of ICT in education

• What is Computer history

• Application of Computer

• What are generations

• What are classifications

• What are general terms

• What is CPU

Any Question please……
