Fundamentals of a Computer

Types of Computer :

1. PC (Personal Computer) :
   • Personal computer is also known as a Microcomputer.
   • It is designed for personal work and applications as Only one user can work at a time.
   • It has a microprocessor as a central processing unit, memory, storage area, input unit and output unit.
   • It is less expansive and easy to use.
   • It does not require the user to have special skills or training to use it.
   • Examples are Laptops and desktop computers.



2. Workstation :
   • Workstation is a single user computer that is designed for technical or scientific applications.
   • It has a faster microprocessor, a large amount of RAM and high speed graphic adapters.
   • It can handle animation, data analysis, CAD, audio and video creation and editing.



3. Mini Computer :
   • It is a midsize multiprocessing computer.
   • It consists of two or more processors and can support 4 to 200 users at one time.
   • It is light weight that makes it easy to carry and fit anywhere.
4. MainFrame Computer:
   • Mainframe computers are designed to support hundreds or thousands of users simultaneously.
   • It can process huge amount of data, e.g. millions of transactions in a second in the banking sector.
   • It is very large in size and is an expensive computer.



5. Super Computer :
   • Supercomputers are the biggest and fastest computers.
   • It can process trillions of instructions in a second.
   • It has thousands of interconnected processors.
   • Supercomputers are used in scientific and engineering applications such as weather forecasting, scientific simulations and nuclear energy research.
   • Examples are Pratyush, Mihir, PARAM 10000, PARAM SHIVAY, PARAM YUVA II, TIANHE-1, JUGENE, Summit etc.
