Classification of Computer According to Size

Q#5: Classify computer according to size. 

Ans: According to Size: Computers are divided into four groups according to their size. 

1. Super computers 

2. Main frame computers 

3. Mini computers 

4. Micro computers 

1. Super Computers: They are the most powerful, fastest and largest computers. They are extremely expensive. They are widely used in scientific application. Examples: weather forecasting, nuclear research, etc. 

2. Main Frame Computers: They are powerful multi-user and multi-processors computers. They process at very high speed. They are expensive and require a lot of technical expertise to be installed and operated. They are used in banks. 

3. Mini Computers: They are smaller than main-frame computers but more powerful than micro-computers. They usually use multi-user operating system. They are used as network servers and internet servers. Examples:DEC VAX, IBM AS/400, etc. 

4. Micro Computers: They are also called personal computers. They use microprocessor. They are cheaper yet faster and more reliable. They are the smallest computers. They are used for documentation, calculation, illustration, entertainment, communication, socialization, etc.

Problem Solving Steps

Q1: Describe the steps involved in problem solving.  Ans:  1) Define the problem:  In problem solving process, the first step is defining or identifying the problem. It is the most difficult and the most important of all the steps. During this stage of problem solving, it is important to describe the problem.  2) Generate alternative solutions: For any problem, there are more solutions to it than the one that is thought of first. Postpone the selection of one solution until several problem solving alternative have been proposed.  3) Evaluate and select an alternative:  Many alternative solution to the problem should be generated before final evaluation. A common mistake in problem solving is that alternative are evaluated as they are proposed, sop the first acceptable solution is chosen even if it is not the best solution.  4) Implement and follow up on the solution:  The plan for best solution also include planning on what happens next if somethi...
