Question No: 28    ( Marks: 1 )

 What is Randomized Algorithm?

Randomized Algorithm:

Any algorithm whose behavior is not only determined by the input, but also values produced by a random number generator

These algorithms are often simpler and more efficient than deterministic algorithms for the same problem. And because of there simplicity they are easier to analyze which is the most important thing in the decision making of an algorithm.

 

Question No: 29    ( Marks: 2 )

 What was the name of first super computer. When it was introduced?

CRAY1 is the first computer and it was introduced in 1973

Question No: 30    ( Marks: 3 )

 How a designer makes Structured Design?

Structured Design is known as a Top-down design.

The designed first conceives about the High level design and then further designs the details of the high level design components and it goes on and on.

Making small changes in the functionality of the systems sometimes leads to major re-design exercise. Structured design separates the functionality from programs data and that’s why program’s deisgned by this methodology are difficult to maintain.

 

Question No: 31    ( Marks: 5 )

 Why microprocessor uses the binary number system and not the decimal or any other number system?

The processor is the logic of a computer and functions comparably to a human central nervous system, directing signals from one component to another and enabling everything to happen. A microprocessor is made from miniaturized transistors and other circuit elements on a single

semiconductor integrated circuit (IC) . These are made up oof semiconductor and silicon.

Microprocessor are composed of components which has only two states either 0 or 1. Binary number system is also composed of these two states.

 

Microprocessor till today only understand the machine language and machine language is only based on binary number system. Even today’s 64 bit microprocessors are also based on this technology.

 

Question No: 32    ( Marks: 5 )

 Why do we need an Interactive Form in a webpage?

  1. Interactive forms are used to gather user data and interact with the user.
  2. Forms can be made interactive with the use of client side scripting and server side sciprting.
  3. In HTML, <FORM> </FORM> tag is used to insert the form in a web page and it always lie in <BODY></BODY> html tag.
  4. without form’s web site is only “READ ONLY”.
  5. with the help of forms a user and can search the contents, place order for goods and services.
  6. Forms can be simple or very complex, based on the requirement.
  7. forms can contain a single element or many e.g text area, buttons
