CMOS (Complementary Metal-Oxide-Semiconductor) is a way of constructing integrated circuits. The technology is used today in microprocessors‚ microcontrollers‚ static RAM‚ and other digital circuits. CMOS utilizes transistors to store information in a volatile manner‚ but is sometimes thought of as non-volatile due to the common use of a battery to maintain the power to the chip‚ and recent changes to using EEPROM technology. In a personal computer‚ the CMOS is mainly used to store settings for

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 unit‚ memory‚ input and output controls) on one small chip.

is the lack of competitors in the industry due to the current financial crisis. Circuit city has long been a direct competitor with Best Buy and one that Best Buy would need to seriously evaluate until recently. Circuit City has faced serious financial losses over the last year. According to Bigcharts.com‚ Circuit City’s stock price has dropped from $16.52 in May 2007 to $.31 in October 2008. Unfortunately‚ Circuit City will not be able to continue to operate with the losses they have faced. According

GENERATION OF COMPUTERS The term generation indicates the type of technology used in the computer construction. As new technology was emerging‚ it was being used in the making of computer. The new technology improved the speed‚ accuracy and storage capacity of the computers. Different technologies have been used for computers in different times. Therefore‚ computers can be divided into five generations depending upon the technologies used. These are: First Generation (1940 - 1956) Second
