Document Summary
Frontside bus: connects the cpu to the ram. Backside bus: connects the cpu o the internal memory (registers and cache) Prefetch unit: loads the next instrucion while the cpu completes the previous task. Decode unit: translates the binary code into instrucions. Control unit: tells the other components what to do and when. Alu (arithmeic logic unit): where the calculaions occur. Cache: collects instrucions and data that are being used oten. Northbridge/southbridge: processors that are intermediaries between the cpu and the peripherals and ram. Lithography: the width of circuits on the cpu. Digital cameras: ccd (charged coupled device) and cmos (complementary metal oxide semiconductor) are two types of light-sensiive diodes that digital cameras use to record photographs. Protons hit the pixels in the camera and become electrons (each light gets. The number of pixels in an image is called the resoluion a number that corresponds to the colour it picked up)
