COMPUTERIntroductionfigurer is the lifeline of modern day civilization . One abide non even think of life without entropy mainframe at present . It has become a day to day need for separately and every individual . Life of even those who are not using or even have not seen a ready reckoner is so heavily dependent on information processing system , that everything will become practically standstill once we fill computers from the society . It is therefore , only natural that we understand this terrific mold called computer . What is a computer ? Computer literally means a person or a finesse which roll in the hay do computing . But then anybody arse do computing and we do not call everybody a Computer . The fact that anybody can do computing can be explained by the fact that the human brain is a very good computer . So , what is a computer ? It is now a days no longer yobbo to define it . The way we perceive computers today is an electronic machine that does a lot of fantastic work . How it do so ? First of all let us define COMPUTERA Computer is a machine which is used for manipulating data according to a list of operating instructions . It can also be define as : A programmable machine having two principal characteristicswhich responds to a specific frozen of instructions andwhich can execute a prerecorded list of instructionsHence , a computer can be defined as an electronic data processing whatchamacallit , capable of accepting data , applying a prescribed set of instructions to the data , and bring outing in some manner or form Therefore , it has a means to accept data by using input devices it has a processor to processor to process the data as per the set of given instructions also termed a program , and a means to display data by means of an output devices . We will pour forth about all this , but lets begin with history of computersThe recital of ComputersWho invented computer ? It is not simple to final result the question .

The answer to the question is that many inventors contributed to the evolution of modern day computersPrimitive examples of automatic calculating devices like Abacus (hypertext transfer protocol /en .wikipedia .org /wiki /Abacus , Slide rule http /en .wikipedia .org /wiki /Slide_ruleand Antikythera mechanisms (http /www .math .sunysb .edu tony /whatsnew /column /antikytheraI-0400 /kyth 1 .html ) can be considered as initial computing devices . In 1837 Charles Babbage coceptualized and designed a experty programmable machinery which was termed as The Computer ( HYPERLINK http /en .wikipedia .org /wiki /computer http /en .wikipedia .org /wiki /computer , it was essentially a mechanical computer . By the end of 19th century a number of technologies had begun to appear which proved useful in the realisation of practical computers .Many new advancements were done during the first half of twentieth century and more powerful and flexible computing devices were constructed in 1930s and 1940s .Vacuum-tube based computers were in use throughout the 1950s but they were largely replaced in the 1960s by transistor-based devices .The transistor-based devices proved to be cheaper...If you want to get a full essay, order it on our website: Ordercustompaper.com
