PCL, short for printer command language, consists of a large set of commands for controlling the Hewlett-Packard LaserJet and DeskJet families of printers, and compatible printers from other manufacturers. PCL commands are used to tell the printer where to place text or graphics on the page, which font to print, whether to print bold, italic or underlined text, and so on.

A drive is the part of the computer that takes the disks or tapes you insert into the slot and spins them to make them work. You probably have at least two different kinds of drives in your system: floppy disk drives are the ones with the little slots where you insert floppy disks; the standard type of hard disk drive comes sealed inside a case, which in turn is stuck inside your computer or inside a separate box-you never even see the disk.

A device just means any kind of component that's part of or attached to your computer. It can be located inside or outside the computer. A mouse, for example, is a device that sits outside the computer, while an internal disk drive (another device) is inside the computer. Devices need instructions on how to communicate with the printer or the rest of the computer, and sometimes those instructions aren't part of the computer's standard operating system.

To understand what defragmentation IS, a person must first understand how data files are saved onto magnetic storage disks. Whether on a floppy disk or a hard disk, data is stored in a certain format. Formatting consists of dividing a disk into organized sections so that data can be located by the computer. Formatting organizes disks into concentric rings called tracks. Tracks are divided into sectors (pie shaped wedges) in which files and parts of files are stored.

Freeware is software made available for public use by the author, and it's free. You're not under any obligation to pay for it. Freeware is usually distributed in the same places you find shareware and public domain software: on bulletin boards, at user groups, and by commercial shareware distributors.

The Desktop level is called a "level" because there is a hierarchy of different levels, kind of like different floors in a tall building. When you can actually see the Desktop, you can double-click to open folders and then you see that folder's window, right? That window is one level of the hierarchy. If you open another folder that is within that window, you go down one more level into the hierarchy. Well, the Desktop level is the very top of the hierarchy (or the root, some might say) because the first window (including the hard disk window) sits on the Desktop.

The video card, as its name indicates is the component the computer whose role is to transmit data on the screen in the control of a microprocessor dedicated and integrated into the card. It is this microprocessor that calculates the position of points on the screen and processes the texture of restitution algorithms for display complex images such as those generated by video games.
