BufferBusBWCache memoryCCDCCIRCCITTCGACharacterChromaChrominanceClockClock pulseCMRRAn intermediate temporary storage device used tocompensate for a difference in data rate and dataflow between two devices (also called a spooler forinterfacing a computer and a printer).A data path shared by many devices, with one ormore conductors for transmitting signals, data orpower. Also, the expansion connector built into acomputer. Boards are inserted into this connector,and all communication between the computer andthe board occurs through the computer’s bus.There are several different expansion busesavailable, including the XT, AT & Micro-Channelbuses for IBM-compatible PCs and the NuBus forthe Apple Macintosh II PC line.Bandwidth.A fast buffer memory that fits between the CPUand the slower main memory to speed up CPUrequests for data.Charge-coupled device (camera).Comité Consultatif Internationale desRadiocommunications.Comite' Consultatif Internationale de Télégraphet Téléphone. An international association thatsets worldwide standards (for example, V.21,V.22, V.22 bis).Color graphics adapter.
