transmitting and receiving data; a PC chipset provides the electronic interfaces between all subsystems. CMOS (complementary metal-oxide semiconductor) CMOS is a widely used type of semiconductor, which features high speed and low power consumption. PCs usually contain a small amount of battery-powered CMOS memory to retain the date, time, and system setup parameters. COM In MS-DOS system, the name of a serial communications port. DOS supports four serial ports.
ECC Memory (error correcting code memory) A type of memory that contains special circuitry for testing the accuracy of data and correcting the errors on the fly. IDE (Integrated Drive Electronics) A type of disk-drive interface widely used to connect hard disks, CD-ROMs and tape drives to a PC, in which the controller electronics is integrated into the drive itself, eliminating the need for a separate adapter card. The IDE interface is known as the ATA (AT Attachment) specification.
PCI (Peripheral Component Interconnect) A local bus standard developed by Intel that first appeared on PCs in late 1993. PCI provides plug and play capability and allows IRQs to be shared. The PCI controller can exchange data with the system's CPU either 32 bits or 64 bits at a time. PnP (Plug and Play) A set of specifications that allows a PC to configure itself automatically to work with peripherals.
