Document Summary
Motherboard - central circuit board which connects all components. Clock speed is number of these operations it can perform per second (mhz, ghz) Ram random access memory; any data anywhere can be accessed anytime (unlike hard discs, cd-roms, digital tape, etc. ) Hard drive non-volatile storage device for digital data. Generally is fixed (non-removable) media (unlike flash drives, floppy drives, etc. ) Expansion cards printed circuit board that can be inserted into slot on motherboard to add functionality, such as video, graphics, sound etc. Instructions run when system is first powered on (booting up) to prepare for other applications to run. Bits all data represented by binary numbers: 8 bits = 1 byte of data. 8 bit, 11khz mono audio file = 11kb/sec. 8 bit, 22khz mono audio file = 22kb/sec. 8 bit, 11khz stereo audio file = 22kb/sec. 16bit, 22khz, mono audio file = 44kb/sec. 16bit, 22khz, stereo audio file = 88kb/sec. 16bit, 44khz, stereo audio file = 176kb/sec.
