CPUThe CPU (Central processing unit) isbasically the brain of the computer,it carrys out the instructions of acomputer program to preform theoperations of a system. The CPU ismeasured in bits and the averagespeed of a computer CPU is usually3.1 Ghz and a laptop is 2.1 Ghz.The faster the CPU the more heatwill be produced which means alarger fan is needed.
Memory RAM ROMRandom Access Memory, Read only memory,is were data is stored cannot be edited.and can be edited. Flash Memory Flash memory can be electrically erased and re-programmed.
Memory DRAM SDRAMDynamic random-access Synchronous DRAM is a muchmemory, the difference faster version of DRAM,between DRAM and RAM is running at 180MHz, dependingthat DRAM stores each bit of on your processor.data in a different capacitor.
Memory EPROM DRAMErasable Programmable Read Only Dynamic Random AccessMemory, this is a memory chip Memory, this stores every bit ofthat contains data when the data in many different capacitorscomputer is turned off. on the chip.
