programming languages is that they are strongly typed and support class-based inheritance. By these criteria, it is easy to dismiss JavaScript as not being a true object-oriented language.

Write differences between Shareware and Trialware software. Answer:

Both shareware and freeware are terms that are used to describe software that can be downloaded from the Internet. The basic difference between shareware and freeware stems from whether the person downloading the software must

pay for it at some time. Freeware is just that, free software, while shareware means that payment will eventually be necessary. When someone downloads freeware, they are often getting software without paying for it. With some freeware downloads, there is an optional charge. This charge may be in the form of a donation or to upgrade the freeware to the

full version of the program. While this software is free, it is still subject to license terms and conditions to protect

Question No: 17 ( Marks: 2 ) Write the major types of softwares with examples? Answer:


Software is the set of instructions which guides the computer hardware through their jobs. A computer is useless without software. We use different software to solve different problems. The types of software we need depend on

the job we want to do.

There are basically two types of software; 1. System software: Application software are programs that interact directly with the user for the performance

of a certain type of work. That work generally falls into one of the following usage areas

2. Application software: Application software are programs that interact directly with the user. They generally

do not talk directly to the hardware.

Question No: 18 ( Marks: 2 ) What is the major difference between paragraph <p> and Line Break <BR> tags? Answer:

p> tag is use to Insert paragraph breaks into the text of your HTML document. Note that this tag is special in that it does not require an ending tag. The <br> tag inserts a single line break. The <br> tag is an empty tag which means that it has no end tag.

Question No: 19 ( Marks: 2 ) Why PASCAL was designed and what is the problem with PASCAL? Answer: Pascal was originally intended primarily as a teaching language. It is very good for writing well-structured and readable

Question No: 22 ( Marks: 5 ) (a) Write down two positive features of client-side scripting. (b) Discuss two deficiencies of JavaScript. Answer (a): 1. Reduced server load as it does not have to send messages to the user’s browser about missing or incorrect data

2. Reduced network traffic as the form’s data is sent only once instead of many to’s and fro’s

Answer (b): 1. It's either embedded in an HTML page or included in an HTML page so it's open source. Anyone can view your code. This can be a bad thing if you have proprietary algorithms. 2. There are no libraries. You can't draw a mass of library functionality to support complex programs. As before

everything is included as ascii text and is downloaded to the client at connect time so large programs are awkward at best. Question No: 23 ( Marks: 5 )

What are the key features of a word processor?

Answer:

Insert text: Allows you to insert text anywhere in the document.delete text: Allows you to erase characters, words, lines, or pages as easily as you can cross them out on paper.cut and paste : Allows you to remove (cut) a section of text from one place in a document and insert (paste) itsomewhere else.copy : Allows you to duplicate a section of text.graphics: Allows you to embed illustrations and graphs into a document. Some word processors let you create the

illustrations within the word processor; others let you insert an illustration produced by a different program.headers , footers , and page numbering: Allows you to specify customized headers and footers that the word processor

will put at the top and bottom of every page. The word processor automatically keeps track of page numbers so thatthe correct number appears on each page.print: Allows you to send a document to a printer to get hardcopy.search and replace : Allows you to direct the word processor to search for a particular word or phrase. You can also

direct the word processor to replace one group of characters with another everywhere that the first group appears.
