Background of the Study
Computer has been defined by different people in different ways computer is the study of a device that accepts information (in the form of digitalized data) and manipulates it for some result based on a program or sequence of instructions on how the data is to be processed. Complex computers also include the means for storing data (including the program, which is also a form of data) for some necessary duration. A computer is a study of a programmable machine. The two principal characteristics of a computer are: It responds to a specific set of instructions in a well-defined manner and it can execute a prerecorded list of instructions (a program).
According to john von neuman, computer is a study of a integrated set of agorithm and data structure which is capable of storing and executing programme. Computer as a study of an electronic device that stores and manipulates information. Unlike a calculator, it is able to store a program and retrieve information from its memory. Most computers today are digital, which means they perform operations with quantities represented electronically as digits. computer is a study of a device that can be instructed to carry out an arbitrary set of arithmetic or logical operations automatically. The ability of computers to follow generalized sequences of operations, called programs, enable them to perform a wide range of tasks.
