 * **Keyword** || **Definition** ||
 * Desktop || A computer designed for desktop use; usually comprises, at a minimum, a central processing unit (CPU), a monitor, and a keyboard as separate units, connected by special cables. ||
 * DNS || Refers to a Domain Name Server. A dedicated server or a service within a server that provides DNS name resolution in an IP network. It turns names for Websites and network resources into numeric IP addresses. DNS servers are used in large companies, in all ISPs and within the DNS system in the Internet, a vital service that keeps the Internet working. ||
 * File Server || A high-speed computer in a network that stores the programs and data files shared by users. It acts like a remote disk drive. The difference between a file server and an application server is that the file server stores the programs and data, while the application server runs the programs and processes the data. ||
 * Server || a server is a computer system that provides services to other computing systems ”called clients” over a network. The term server can refer to hardware (such as a Sun computer system) or software (such as an RDBMS server). ||
 * FAT || An area on a hard disk or floppy disk where information is stored about the physical location of each piece of every file on the disk and about the location of unusable areas of the disk. File Allocation Table (FAT) is a partially patented file system developed by Microsoft for MS-DOS and is the primary file system for consumer versions of Microsoft Windows up to and including Windows Me. ||
 * NTFS || (NT File System) An optional file system for Windows NT, 2000 and XP operating systems. NTFS is the more advanced file system, compared to FAT32. It improves performance and is required in order to implement numerous security and administrative features in the OS. ||
 * Virtual Memory || An imaginary memory area supported by some operating systems (for example, Windows but not DOS) in conjunction with the system hardware. You can think of virtual memory as an alternate set of memory addresses. Programs use these virtual addresses rather than real addresses to store instructions and data. ||
 * Hard Drive || The primary computer storage device, which spins, reads and writes one or more fixed disk platters. ||
 * CD-ROM/RW drive || A device that holds and reads CD-ROM discs. CD-ROM drives, which today typically means a CD-RW drive that is a combo CD-ROM, CD-R and CD-RW drive, come in a variety of speeds. ||
 * Fragmentation || Refers to the condition of a disk in which files are divided into pieces scattered around the disk. Fragmentation occurs naturally when you use a disk frequently, creating, deleting, and modifying files. ||
 * Floppy || Short for floppy disk drive (FDD), a disk drive that can read and write to floppy disks. ||
