Chips and motherboard

  1. 1. CHIPS AND MOTHERBOARD<br />
  2. 2. A chip is also called an integrated circuit. Generally it is a small, thin piece of silicon onto which the transistors making up the microprocessor have been etched. A chip might be as large as an inch on a side and can contain tens of millions of transistors. <br />
  3. 3. A microprocessor (alsoknown as CPU) is a complete computationenginethatisfabricatedon a single chip. <br />Thefirstmicroprocessorwasthe Intel 4004, introduced in 1971. <br />Allitcould do wasadd and subtract. Itcouldonlyworkwith 4 bits at a time.<br />Thisisthe Intel 8080, thefirstmicroprocessorfor a home computer. <br />Itwasintroduced in 1974 and couldworkwith 8 bits at a time.<br />
  4. 4. A microprocessordoesthreethings:- Usingits ALU (Arithmetic/LogicUnit) themicroprocessor can performmathematicaloperationslikeaddition, subtraction, multiplication and division.- A microprocessor can move data fromonememorylocationtoanother.- A microprocessor can makedecisions and jumptoanother set of instructionsbasedonthosedecisions.<br />
  5. 5. Thisis a ROM chip. On a PC the ROM chip iscalledthe BIOS (Basic Input Output System). Whenthecomputerstarts, themicroprocessorexecutestheinstructionsitfinds in the BIOS. <br />Thisis a RAM chip. RAM contains bytes of informationthatthemicroprocessor can readorwrite. <br />Oneproblemwithtoday’s RAM chips isthattheyforgeteverything once thepowergoes off. Thatiswhythecomputerneeds ROM.<br />
  6. 6. Whenyoutakethe case off of a computeryou can see a piece of equipmentthattiesallthecomponentstogether. <br />It’sthemotherboard, thatallowsalltheparts of thecomputertoreceivepower and communicatewithoneanother.<br />Thisis a graphiccard. <br />Likethemotherboard,itis a printedcircuitthathouses a processor and a RAM. <br />
