Inside of the mysterious box that perches ominously on your desk is champion ofthe marvels of the modern terra firma. This marvel is also a total enigma to roughly ofthe population. This enigma is, of course, the microprocessor. To an averageobserver a microprocessor is simply a thin gather of black plastic that is foundinside of almost everything.In How Microprocessors Work they atomic number 18 defined as a computers central treat unit, usually contained on a single integrated circuit (Wyant andHammerstrom, 193). In plain English this simply means that a microprocessor isthe brain of a computer and it is only on one chip. Winn L. Rosch compares themto being an electronic combining weight of a knee-joint that when struck with theproper digital stimulus pass on act in the exact same way each time (Rosch,37).to a greater extent practically a microprocessor is multitudinous transistors squeezed onto assmall a piece of silicon as possible to do math problems as closely as poss ible.Microprocessors are made of many smaller components which all mouldtogether to make the chip work. A really good doctrine of analogy for the way the innerworkings of a chip operate arse be found in How Microprocessors Work. In theirbook, Wyant and Hammerstrom describe a microprocessor as a grinder and all ofthe inner workings of the chip as the various parts of a factory (Wyant andHammerstrom, 71-103). Basically a microprocessor give the gate be seen as a factorybecause like a factory it is sent something and is told what to do with it. Themicroprocessor factory processes info. This most basic unit of thisinformation is the tour. A bit is simply on or off. It is either a one or a zero.Bits are put into 8 bit groups called bytes. The number 8 is used because it isoffers enough combinations to encode our entire dustup (28=256). If only 4bits are used only (24=16) combinations would be possible. This is enough toencode 9 digits and some operations. (The first microprocessor s plycalculators) A half byte is called a nibble and consists of 4 bits. In the worldof computer graphics the combination of bits is easier seen. In computergraphics bits are used to make color combinations, thus with more bits more colour are possible. Eight bit graphics will display 256 colors, 16 bit willdisplay 65,536, and 24 bit graphics will display 16.7 million colors. The busunit is described as the tape drive dock because it controls data transfers, andfunctions between the individual pieces of the chip. The part of the chip that
