Introduction To It

invoice of computer electronic computer definition - Is a programmable apparatus which responds to a specific set of instructions and pre records inclination of instructions which argon known as programmes. data processor History and genesiss Abacus computers - These were the first computers seam of only doing increase and subtraction Pascaline - This was a mathematical calculator which per changes addition and subtraction G.W Leinbiz - Stepped up cognitive process and uses carrier bag card for computer storage of in sortingation, they had got special map besides addition and subtraction, and also performs square substructure functionality Charles Babbage - Uses engine and could compute data and store data and information. They were uninflected machine which works as the present computers First Generation Computers Computer maiden  coevals was in the 1940s and since thus a service of radical break -through of electronic visualize has occurred with e ach(prenominal) major break-through of computer based upon the older form of electronic design being replaced by a modern form and this is called computer generations. The world-class generation of computer was these computers whose computer computer architecture was based on massive electronic valve (vacuum tube). e.g. electronically digital vacuum computers, universal vacuum computer UNVAC.

Other characteristics of 1st generation Computers 1946 - 1959 * These computers uses vacuum tube for data processing and storage * They had a memory size of 20bytes speed of 5mbps * They produced a sess of heat * These computers were treacherous and could not work fast with a lot of data. * They uses punch card for! data storage * The software engineer were machine dependent * First generation consume a lot of power Second Generation of Computer - second Generation computers were more reliable and faster in exploit (read and write operations) than the 1st generation which was massive, instead of valves wide-eyed transistors were utilize in design e.g. ATLAS computers Characteristics of 2nd generation...If you need to contain a full essay, order it on our website: OrderEssay.net
