Bleed refers to any element on a page that is printed beyond the edge of the paper. Whenever you see anything (text, graphics, photographs) that is printed right up to the edge of the paper, it was actually printed onto larger paper over the margin guidelines, and the paper was trimmed.

Information that is digital is information represented by numbers (digits) or more broadly, information that can be measured in discreet, exact values. The opposite term is analog, which describes information represented along a continuous range, where there are an infinite number of possible values. Trite as it may be, the best way to understand the difference between digital and analog is to compare a digital clock to a traditional round clock with hands.

A bug is a problem in software or hardware; to debug is to diagnose and correct said problem. Software programs inevitably develop bugs due to mistakes in planning or simply from accidentally typing the wrong command. Before a program can run properly, all bugs have to be found and corrected. A debugger is an application developed for the specific purpose of finding these problems; it lets the programmer run the program one step at a time so that she can see exactly where the mistake occurs.

(Dual In-line Memory Module) A small PRINTED CIRCUIT BOARD with RAM chips mounted on both sides and a single edge connector, via which it can be plugged into a computer MOTHER BOARAD. DIMM differs from a SIMM in that the chips on either side have separate pins on the edge connector, permitting a wider 128-bit data path for faster access to the memory; hence they tend to be used in more expensive systems like servers.

clock cycle The basic unit of timing within a computer system, consisting of one of the stream of regular pulses generated by the SYSTEM CLOCK. Most of a computer's components, in particular its processor, bus and memory systems, operate in strict step with the clock, so the number of clock cycles their various actions occupy is of crucial importance to a computer designer.

Boot Record: A set of crucial data written on the BOOTSECTOR of a HARDDISK or FLOPPYDISK that contains the information required by the INITIAL PROGRAM LOADER to locate a copy of the operating system on the disk and load it into memory. Damage to the boot record can prevent the computer from booting from that disk, and render the disk's other contents inaccessible; many disk repair utilities work by preserving and restoring backup copies of the boot record. Some types of VIRUS hide themselves within the boot record.

Sometimes, like in a school computer lab or in an office, you need to hook up several computers to one printer, or several computers need to connect to one file server, or maybe you have several devices (such as a scanner and a CD-ROM player) that you need to hook into one computer. Well, the only way to connect all these devices together, since there is only one port, or connecting place, on the back of the computer, is to connect each object (each device) to the next one in line, making a daisy chain.

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.

Desktop publishing (DTP) is the process of creating printed documents that look professionally produced, using page layout software running on a personal computer, along with a high-quality, yet affordable, printer. To publish something with the traditional method, you would send typed or handwritten text to a typesetter, who would turn it into typeset text called "galleys," which took a couple of days. If there were corrections, it took another couple of days to get those back. If you didn't know how to layout the pages yourself, you'd take the galleys to a print shop, along with your art (illustrations and photographs).

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.
