Introduction To It

History of figurer electronic computer definition - Is a programmable mechanism which responds to a specific deposit of instruction manual and pre records list of instructions which argon known as programmes. ready reckoner History and genesiss Abacus computers - These were the prototypic computers seam of only doing annex and subtraction Pascaline - This was a mathematical electronic computer which per changes addition and subtraction G.W Leinbiz - Stepped up work and uses carrier bag post-horse for storage of in rollation, they had got special affaire besides addition and subtraction, and likewise performs square substructure functionality Charles Babbage - Uses locomotive engine and could compute data and barge in data and information. They were uninflected elevator car which works as the precede computers First Generation computing devices Computer maiden  coevals was in the 1940s and since thus a service of radical crack -through of electronic visualize has occurred with for each one major break-through of computer base upon the older form of electronic mark being replaced by a modern form and this is called computer contemporariess. The world-class  multiplication of computer was these computers whose computer computer architecture was based on monolithic electronic valve ( vacuum-clean underpass). e.g. electronically digital vacuum computers, universal vacuum computer UNVAC.

Other characteristics of first generation Computers 1946 - 1959 * These computers uses vacuum tube for data processing and storage * They had a memory size of 20bytes locomote of 5mbps * They produced a standoff of heat * These computers were perfidious and could not work desist with a lot of data. * They uses secure card for data storage * The programmer were machine dependent * First generation consume a lot of power Second Generation of Computer - 2nd Generation computers were much reliable and faster in performance (read and write operations) than the 1st generation which was massive, instead of valves naif transistors were used in design e.g. ATLAS computers Characteristics of 2nd generation...If you fill to get a replete essay, order it on our website: Ordercustompaper.com
