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

1. Define Modulation Modulation process of putting information onto a high-frequency carrier for transmission. 2. What is carrier frequency? In essence‚ then the transmission takes place at the high frequency (the carrier) which has been modified to “carry” the lower-frequency information. 3. Describe the two reasons that modulation is used for communications transmission. The modulated stage accepts two inputs‚ the carrier and the information (intelligence) signal. 4

1. Rationale of the study Our new technology the energy transfer wherein energy can be transferred from a source to a load via coupled magnetic resonance in the non radiative near field that can be used in some equipment that used in some electric energy as a source like the electric vehicles (EVs). We can use this energy transfer as a charger to EVs by microwave beams and laser beams to realize the remote energy supply using directional antenna. However when there is a obstruction in the path

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

Second Generation Computers (1956-1963) The computers built in the 1950s and 1960s are considered the 2nd generation computers. These computers make use of the transistors invented by Bell Telephone laboratories and they had many of the same components as the modern-day computer. For instance‚ 2nd generation computers typically had a printer‚ some sort of tape or disk storage‚ operating systems‚ stored programs‚ as well as some sort of memory. These computers were also generally more reliable

Introduction: Computer Generations History of development of computers down the years is referred as Computer Generations. A generation refers to research and development done to improve the performance of computers. It also refers to the new technical breakthroughs and advancements in computers. A generation has significantly decreased the size of computers and increased the performance. With the increase in speed‚ power and memory and decrease in size‚ each generation has brought down the cost
