COMn - The device names for the serial ports on your system. control panel - The part of the system that contains indicators and controls, such as the power button and power indicator. controller - A chip or expansion card that controls the transfer of data between the processor and memory or between the processor and a peripheral device. coprocessor - A chip that relieves the system's processor of specific processing tasks. A math coprocessor, for example, handles numeric processing. CPU - Central processing unit. See processor. DC - Direct current. DDR - Double-data rate. A technology in memory modules that potentially doubles the data rate by transferring data on both the rising and falling pulses of a clock cycle. device driver - A program that allows the operating system or some other program to interface correctly with a peripheral. DHCP - Dynamic Host Configuration Protocol. A method of automatically assigning an IP address to a client system. diagnostics - A comprehensive set of tests for your system. DIMM - Dual in-line memory module. See also memory module. DNS - Domain Name System. A method of translating Internet domain names, such as www.example.com, into IP addresses, such as 208.77.188.166. DRAM - Dynamic random-access memory. A system's RAM is usually made up entirely of DRAM chips. driver - See device driver. DVD - Digital versatile disc or digital video disc. ECC - Error checking and correction. EMI - Electromagnetic interference. ERA - Embedded remote access. ERA allows you to perform remote, or "out-ofband," server management on your network server using a remote access controller. ESD - Electrostatic discharge. ESM - Embedded server management. expansion bus - Your system contains an expansion bus that allows the processor to communicate with controllers for peripherals, such as NICs. expansion card - An add-in card, such as a NIC or SCSI adapter, that plugs into an expansion-card connector on the system board. An expansion card adds some specialized function to the system by providing an interface between the expansion bus and a peripheral. 2
