Computer Engineering

.  A computer is simple hardware that cannot do anything without software. The software gives life to hardware or device. It is possible to solve problem using computer by writing appropriate programs in different high level language. If our instruction or program is wrong computer doesn't give right result thus before writing program we should follow the steps. Problem Analysis Algorithm Development Flowchart Development Coding Computation and Execution Debugging and Testing Documentation 1. Problem Analysis : Problem analysis is a process to analyze the problem that will be solved with a computer program before solving the problem. It should be analyzed and understood clearly about solution and identification of input, process and output. 2. Algorithm Development : An algorithm is simple English language step by step description of the method to solve a problem. It manage sequence of steps of problem.

. There are 5 generation of computer 1. First Generation of Computer (1946-1955) : The period of first generation was from 1946-1959. The first generation of computers used a large number of vacuum tubes and thus generated a lot of heat. They were very large in size, slow in processing and has less storage capacity. In this generation, magnetic cores were used as the primary memory and magnetic tape and magnetic disks as secondary storage devices. It used machine level language so the were difficult to program. Example : ENIAC  ( Electronic Numerical Integrator and Computer),  UNIVAC (Universal Automatic Computer) ,  IBM650 etc. Features of the first generation are: Vacuum tube technology Consumes lot of electricity Slow input and output devices Supported machine language only Generates lot of heat Need of AC 2. Second Generation of Computer (1956-1965): The generation using the semiconductor transistor was the revolution in the field of computer. The transistor replace the vacuum tube
