1. C lassification of computer on the basic of size

2. Hello! I am Nirajan silwal I am here because I love to give presentations.

3. SUPER COMPUTER 1

4. Super computer is the most powerful and fastest computer among digital computer. T his computer is special purpose and is capable of handling huge amount of calculations that are beyond human capabilities. I t can perform at billions of instructions per second(BIPS). Super computer has the computing capability equal to that 40,ooo microcomputer.

5. This computer is most expensive computer(cost about 15-20 million dollar range). It is used only by large organization like: NASA,UNIVERSITIES & GOVERMENT AGENCIES, mainly in the area of defence and weaponry, weather forecasting , satellite communication, nuclear research etc. It requires large space and temperature controlled room. Examples:NEC-500,CRAY X-MP/24 etc.

6. MAINFRAME 2

7. Mainframe is large, powerful system. Although this system offers high processing power , they lack in flexibility. It is designed for large-scale data processing. It is very large in size with area of 1000sq.ft. It supports large number of terminals, more than 100 terminals. It is suitable for big organization such as bank ,insurance companies, airlines , railway system.

8. Example : IBM 1401,ICL 39,and CYBER 170.IBM 1401 was the first computer brought to N epal .

9. MINICOMPUTER 3

10. First released in the 1960s. Minicomputer got its name because of its smaller size and cost compared to mainframe. The capabilities of a computer is somewhere between mainframe and micro computer. For the reason micro computer is also called midrange computer. Like mainframe , minicomputer can handle much more input and output than microcomputer.

11. It can support 50 terminals and requires area of around 100 sq ft. This computer is useful for small business organizations, industries, banks, universities. Example : prime 9755, HCL, CDC-1700 etc.

12. MICROCOMPUTER 4

13. A computer which is based on microprocessor, is called microcomputer. It is a small, low cost digital computer. It requires small space, can be placed on a table or even kept inside a briefcase. This computer has central processing unit on a single chip. It is mainly use in office, house, school, shop, and store. Example :IBM PC,APPLE/MACINTOSH. Microcomputer can be further categorized as: non-portable & portable.

14. The microcomputer in non-portable category can be: Personal computer Workstation The microcomputer in portable category is: Laptop Notebook Table pc Palm top PDA(personal digital assistant).
