Basics of Computer Science Fundamental Concept A computer is basically a programmable machine capable to perform arithmetic and logical operations automatically and sequentially. It is also known as a data processor, as it can store, process, and retrieve data as per the wish of the user. Data processing involves the following three activities − Input of data Manipulation/processing of data Giving output (i.e. management of output result) In computer system, data is arranged orderly and systematically. The term “computer” is derived from a Latin term “compute,” which means ‘to calculate.’ Initially, the computer system had been designed to calculate; it was intended to be a computing device. However, over a period of time, this device technically advanced; at present, it can perform a wide range of desirable works apart from data processing. Major Functions of Computer System Following are the core functions of a computer system − A computer accepts the command and/or data as inp...
