What is computer?
The word computer is derived from the Latin word "Computare" which means to calculate. Basically, computer is defined as a programmable machine which is computer. computer is an electronics machine that can accept data ; process it according to a set of predefined instruction and then gives the result. Computer is an advanced electronic device that takes raw data as input from the user and process these data under the control of set of instructions called program, it gives the result from the output. It can process both numerical and non-numerical ( arithmetic and logical) calculations.
Computers are categorized by both size and the number of people who can use them concurrently. Supercomputers are sophisticated machines designed to perform complex calculations at maximum speed; they are used to model very large dynamic systems, such as weather patterns. Mainframes, the largest and most powerful general-purpose systems, are designed to meet the computing needs of a large organization by serving hundreds of computer terminals at the same time. Minicomputers, though somewhat smaller, also are multiuser computers, intended to meet the needs of a small company by serving up to a hundred terminals. Microcomputers, computers powered by a microprocessor, are subdivided into personal computer and workstations, the latter typically incorporating RISC processor. Although microcomputers were originally single-user computers, the distinction between them and minicomputers has blurred as microprocessors have become more powerful. Linking multiple microcomputers together through a local area network or by joining multiple microprocessors together in a parallel-processing system has enabled smaller systems to perform tasks once reserved for mainframes, and the techniques of grid computing have enabled computer scientists to utilize the unemployed processing power of connected computers.
Advances in the technology of integrated circuits have spurred the development of smaller and more powerful general-purpose digital computers. Not only has this reduced the size of the large, multi-user mainframe computers-which in their early years were large enough to walk through-to that of large pieces of furniture, but it has also made possible powerful, single-user personal computers and workstations that can sit on a desktop. These, because of their relatively low cost and versatility, have largely replaced typewriters in the workplace and rendered the analog computer inefficient.
By creating this type of integrated computer, the benefits of both analog and digital computing are readily available. A hybrid computer is extremely fast when it comes to managing equations, even when those calculations are extremely complicated. This advantage is made possible by the presence of the analog components inherent within the design of the equipment

- Analog Computers
- Digital Computers
- Hybrid Computer
Hybrid computer are computers that are designed to provide functions and features that are found with both analog computers and digital computers. The idea behind this combined or hybrid computer model is to create a working unit that offers the best of both types of computers. With most designs, the analog computers of equipment provide efficient processing of differential equations, while the digital aspects of the computer address the logical operations associated with the system.
By creating this type of integrated computer, the benefits of both analog and digital computing are readily available. A hybrid computer is extremely fast when it comes to managing equations, even when those calculations are extremely complicated. This advantage is made possible by the presence of the analog components inherent within the design of the equipment
