language that can be understood by computers). These computers were limited to solving one problem at a time. Input was based on punched cards and paper tape. Output came out on print-outs. The two notable machines of this era were the UNIVAC and ENIAC machines – the UNIVAC is the first every commercial computer which was purchased in 1951 by a business – the US Census Bureau. Second Generation (1956 – 1963) – Transistors The replacement of vacuum tubes by transistors saw the advent of the second

INTEL 4004 in November‚ 1971‚ a company called Intel publicly introduced the world’s first single chip microprocessor‚ the Intel 4004 (U.S. Patent #3‚821‚715)‚ invented by Intel engineers Federico Faggin‚ Ted Hoff‚ and Stanley Mazor. After the invention of integrated circuits revolutionized computer design‚ the only place to go was down -- in size that is. The Intel 4004 chip took the integrated circuit down one step further by placing all the parts that made a computer think (i.e. central processing

2 Areas of data processing 1. Business Data processing (BDP) . Business data processing is characterized by the need to establish‚ retain‚ and process files of data for producing useful information. Generally‚ it involves a large volume of input data‚ limited arithmetical operations‚ and a relatively large volume of output. For example‚ a large retail store must maintain a record for each customer who purchases on account‚ update the balance owned on each account‚ and a periodically present a

important contributions to computer science‚ von Neumann is best known for his EDVAC (Electronic Discrete Variable Automatic Computer) which opposed the not yet released ENIAC (Electronic Numerical Integrator and Computer). Neumann’s EDVAC design was intended to resolve many of the problems created by the ENIAC’s design. The ENIAC was designed to operate in decimal‚ whereas the EDVAC was designed to work in binary. These specific types of computers had to be physically rewired in order to perform

The field of Computer Science has made tremendous innovative advances since its inception. The first digital computer‚ the ENIAC‚ was used by the Army to provide calculations in designing the hydrogen bomb. It weighed more than twenty-seven tons and measured approximately six-hundred and eighty square feet. Developments in Computer Science are occurring at a very fast rate. An example of this can be found in the area of wireless information systems. Today‚ Computer Science‚ with regard to wireless
