Data The information a system stores and processes. DC Direct current. A voltage or current that does not fluctuate periodically with time. Default Value A pre programmed value to be used if you fail to set your own. DHCP Dynamic Host Configuration Protocol A protocol used to automatically acquire parameters required for the communication, such as IP address. The sender of IP address is called a DHCP server, and the receiver is called a DHCP client. DIMM Dual-in-line memory module. Disk A spinning platter of magnetic data storage media. If the platter is very stiff it is a hard drive, if it is highly flexible it is a floppy disk, if it is a floppy disk in a hard housing with a shutter it is commonly called a diskette. Disk Drive The hardware which spins the disk and has the heads and control circuitry for reading and writing the data on the disk. Diskette A floppy disk in a hard housing with a shutter. DMA Direct Memory Access. Special circuitry for memory to memory transfers of data which do not require CPU action. DMI Desktop Management Interface. A standard that provides PC management applications with a common method of locally or remotely querying and configuring PC computer systems, hardware and software components, and peripherals. DNS Domain Name System A function to control the association between the IP address and the name assigned to the computer. 80 If you do not know the IP address but if you know the computer name, you can still communicate to that computer. DOS Disk Operating System (MS-DOS is a Microsoft Disk Operating System). Driver A computer program which converts application and operating system commands to external devices into the exact form required by a specific brand and model of device in order to produce the desired results from that particular equipment. DVMT Dynamic Video Memory Technology A video memory architecture that increases the efficiency of the motherboard by using innovative memory utilization and direct AGP. ECP Extended Capability Port. A set of standards for high speed data communication and interconnection between electronic devices. Encryption Key (Network Key) Data encryption key used to encrypt message text and for computing message integrity checks. Data encryption protects data from unauthorized viewing. This device uses the same encryption key to encode and decode the data, and the identical encryption key is required between the sender and receiver. ESD Electro-Static Discharge. The sudden discharge of electricity from a static charge which has built-up slowly. Example: the shock you get from a doorknob on a dry day or the sparks you get from brushing hair on a dry day. Extended Memory All memory more than the 640KB recognized by MS-DOS as system memory. FCC Federal Communication Commission. Floppy Disk A spinning platter of magnetic data storage media which is highly flexible. GB Gigabyte.
