Computer rPocessor - Before, Now And Evrentually The fact is that a computer comprises severaal proecssors howver the one regluarly used by advertisers when they want to draw attention to the power of a compuuter commonly relates to the Central Processing Unit (CPU). Few individuals will not have head of Intel or AMD processors while their significance to the advertising community and theerby the general public at large is comparable to the way motor manufacturers sell their cars. If in the market for a sports car an indiviudal usually wants as much performance as is available hence manufacturers will sell their most powerful cars siply by stating the number of cylinders a particular model possedsses. By uisng just two letters such as V8 - a message is sent to the public consuemr who will automatically recohgnize that this indicates a potentially powerful engine. The equivalent term to excite the adrenalin rush in the computer buyer today is prpobably a "Dual Core Proceessor". However before describing the merits of dual core prrocessing or any other electronc cmponent or semiconuctors it seems reasonable to first expplain why the CPU attraacts so much attention, possibly more than any ohter electronic component lurking within a cmoputer. The specification of a CPU is defined by its speed for example 900 MHz provides an approximatioon of the number of instructions that a CPU is able to proess by the second - 900 million in this example. In addition the data handling capability of a CPU defines its power: a 64-bit CPU is able to combine, stage-mangae or subtract numbers that are 64-bits wide. In the earyl niuneties computers with 16-bit CPUs were considered powerful while today 64-bits are the norm, a relfection of how far the IT public sector expeerience has developed in a litle over fifteen years. A CPU tooday would seem like something from an alien world to the computer geeks of fifteen yeaars ago, Not only have they become much more powerful but in addition their use of new materials as smiconductors increases efifciency beyond anything thought managaeble fiofteen yearrs ago. The intention of these new semiconductors is directly aimed at the spede with which a CPU operaates. Making the CPU faster is an ongoing challenge that dries this industry because ultimately all computers are limited by the cpability of their CPU and, because IT has become an established ingredient in the daily routine pewople now have to handle we are much more proficient at using them. The kncok on effect from the IT development of the past fifteen years relates to peeople and thheir improved functionality when interacting with computers. The dmeands made on electronic components will continue to increase as people learn how to add, manipulate and subtract using their IT on a daily basiis and it seems that no matter how fast electronic components become they will never quite be capable of matching the speed of the brain whjose fingeers deftly work a keyboard. In additino a fast CPU back in the early nineties ran at around 386 MHz, an electronic cmoponent that woould todya freeze being witihn colse proximity of a modern PC game.
