Stands for delta channel and is a 16Kbps circuit-switched channel. Used to manage control signals.
To connect a series of devices, one after the other. When signals are transmitted on a daisy chain, they go to the first device, then to the second, and so on, until termination is reached.
A type of computer that maintains information records that can be added, deleted, changed, or searched. Database servers play a major role in most companies and on the Internet.
The reorganization of data on a hard disk to optimize performance.
To convert an analog signal back to digital data. This is typically done on the receiving end of a computer transmission using standard phone service.
To prevent a user from using other permissions to access a resource. It is far stronger in its effects than simply not giving them permissions.
Manages the dialog between the sender and receiver. It consists of managing the transfer of data, determining whether an acknowledgment is required, and determining the appropriate responses to the sender.
Uses the archive bit to determine which files have changed since the last normal backup. Files that have changed are backed up. The archive bit is not reset until the next normal backup. If you have to restore data, you need only your last full backup and your last differential tape.
A digital signaling method used to transmit data over regular phone lines at speeds up to 6Mbps. DSL uses Asynchronous Transfer Mode to pass data in fixed-size cells.
Based on the same technology as the CD-ROM, DVDs use a much smaller laser and are able to copy many times more the amount of data. DVDs can hold at least 4.7GB of data and as much as 8.5GB.
Deutsch Industrie Norm-a German standards organization.
DMA enables a device to transfer data directly to RAM without using the attention of the processor for the entire transfer period. The result is a faster and more direct method of data transfer.
Uses a hierarchical database to logically organize the network resources. This model scales well to small, medium, or large enterprise networks.
Manages floppy and hard disks. It can be a separate piece of hardware, or it can be integrated with the hard drive.
The process of creating logical disks from a physical disk. You can then format the logical disks and use them to store data.
Sharing the task of processing instructions between a server and a client CPU.
Logically groups computers, users, and groups into a domain. Users log on to the domain and have access to any resources within the domain to which their user account has permission.
A system that resolves domain names to IP addresses by using a domain name database.
An operating system developed by Microsoft. DOS predominantly uses command lines to manage the operating system, applications, and files.
The name that is used to describe the software that makes up the DOS user interface.
A DOS utility that enables the user to customize settings for DOS and add key commands for DOS.
Measures the distance, in millimeters, between two dots of the same color on the monitor.
Software that shows a particular operating system (Windows 2000, for instance) how to access and interact properly with a specific device (an HP Color LaserJet 4000, for instance). Each piece of hardware therefore may require a different driver for every operating system it is installed in.
A set of tiny switches attached to a circuit board that are manually configured to alter the function of a chip for a specific computer or application.
Having two or more operating systems on your computer. At system startup, you can select which operating system you will boot.
Automates the assignment of IP configuration information.
Automates the assignment of IP configurations.
