computer and it's generation

Computer and It's GENERATION Let us first define the term computer. Computer is defined in the Oxford dictionary as "An automatic electronic apparatus for making calculations or controlling operations that are expressible in numerical or logical terms." The definition clearly categorise computer as electronic apparatus although the first computers were mechanical and electromechanical apparatus. The definition is also pointing towords the two major areas of computer application viz. data processing and computer assisted controls/operations. The another important confluence of the definition is the fact that the computer can perform only those operations/calculations which can be expressed in logical or numerical terms. Computer Generation From the early 1940's to the present, Computer scientists have been able to identify clear-cut stages in the development of computer technology. With each stage, radical change in electronics have taken place. As a resu...

Classification of computer based on their cost size and confriguration.

TYPES OF COMPUTER Computer and it's Type Computers are classified by the type of data they are desinged to process. Data may be obtained either as a result of countig of through the use of same measuring instrument. Data that are obtained by counting are called discreate data are total numbers of students in a classroom. Data that must be obtained throgh measurement are called continous data. For example, continious data are the speeds an automobile measure by speedmotor or the tempreature of a patient as masured by a thermometer. Classification of computer based on their cost size and confriguration. In this category computers are classified as micro-computer. mainfraim compute...

History of C language

. History of C Language History of C language is interesting to know. Here we are going to discuss brief history of c language. C is an imperative procedural language.C is a general-purpose language which has been closely associated with the UNIX operating system for which it was developed - since the system and most of the programs that run it are written in C. C programming language was developed in 1972 by Dennis Ritchie at bell laboratories of AT&T (American Telephone & Telegraph), located in U.S.A. C was developed at Bell Laboratories as a system programming language to implement a new operating system on a DEP PDP-11 minicomputer. The project began in 1972, and a language description was published six years later (Kernighan and Ritchie, 1978) [C is a compact terse programming language that includes data types, data separations, the ability to manipulate addresses, and uncomplicated but complete set of flow control constructions. Dennis Ritchie is known as the fo...
