3. I ntroduction to Computer 01 A computer is a programmable machine that receives input, stores and manipulates data, and provides output in a useful format. ▪ A computer is a machine that manipulates data according to a set of instructions. ▪ A computer is a machine for performing calculations automatically

4. Based on signal computer can be classified as: ▪ Analog Computer ▪ Digital Computer ▪ Hybrid Computer Based on capacity and structure computer can be classified as: ▪ Super Computer ▪ Mainframe Computer ▪ Mini Computer ▪ Micro Computer C omputer classification

5. A computer that represents data in terms of physical measures or quantities and proceeds along a continuum constituted by its components . ▪ An analog computer can work both mechanically and electronically ▪ Analog computer handles continuous variables ▪ Analog Computer can carry out multiple tasks simultaneously Analog computer

6. D igital computer A computer that stores data in terms of digits and proceeds in discrete steps from one state to the next . A computer that stores data in terms of digits and proceeds in discrete steps from one state to the next.

7. H ybrid computer Hybrid computers are computers that exhibit features of analog computers and digital computers. The digital component normally serves as the controller and provides logical operations, while the analog component normally serves as a solver of differential equations.

8. Super computer The largest computers are supercomputers . They are the most powerful, the most expensive, and the fastest. They are capable of processing trillions of instructions per second . Examples of users of these computers are governmental agencies, such as the IRS, the National Weather Service, and the National Defense Agency.

9. M ainframe computer Mainframe Computer: Large computers are called mainframes . Mainframe computers process data at very high rates of speed, measured in the millions of instructions per second. They are very expensive, costing millions of dollars in some cases. Mainframes are designed for multiple users and process vast amounts of data quickly.

10. M ini computer A minicomputer is a class of multi-user computers that lies in the middle range of the computing spectrum, in between the largest multi-user systems (mainframe computers) and the smallest single-user systems .

11. M icro computer A microcomputer is a computer with a microprocessor as its central processing unit. They are physically small compared to mainframe and minicomputers. Many microcomputers are also personal computers .
