CHKDSK (Check Disk) An MS-DOS command that gives you information such as disk space, files, and directories on your hard disk drive. COM Port COM is a logical device name used to designate the computer serial ports. Pointing devices, modems, and infrared modules can be connected to COM ports. Each COM port is configured to use a different IRQ and address assignment. CPU (Central Processing Unit) The CPU, sometimes called "Processor," actually functions as the "brain" of the computer. It interprets and executes program commands and processes all the data stored in memory. Currently, there are socket 7, slot 1, and slot 2 CPUs. Intel Pentium Processors fit on socket 7, Intel Pentium II fit on slot 1, and Intel Xeon fit on slot 2. FDISK (Fixed Disk Setup Program) An MS-DOS program used to partition the hard disk drive. FDISK is required to setup a new non-RAID hard disk drive before formatting and installing an operating system. IDE (Integrated Drive Electronics) IDE devices integrate the drive control circuitry directly on the drive itself, eliminating the need for a separate adapter card (in the case for SCSI devices). UltraDMA/33 IDE devices can achieve up to 33MB/Sec transfer. LPT Port (Line Printer Port) Logical device name reserved by DOS for computer parallel ports. Each LPT port is configured to use a different IRQ and address assignment. PCI Bus (Peripheral Component Interconnect Local Bus) PCI bus is a specification that defines a 32-bit data bus interface. PCI is a standard widely used by expansion card manufacturers. V. Appendix Glossary 40 AP3000 Hardware Reference Guide
