3]GLOSSARY 3]AMIGADOS The Amiga's Disk Operating System. Derived from TRIPOS at Cambridge University. 3]AUTOCONFIG The ability of the system to automatically recognise external devices, such as hard disks and RAM expansion units. 3]ALERT A system message displayed when there is a serious problem. 3]AUDIO CONNECTOR What is used to connect audio equipment to the Amiga. 3]BAUD RATE The speed that information is passed through the serial port. (Usually by Modem). 3]BIT-MAP A rectangular array of pixels which represents an area of memory. 3]BLITTER From "BLT" or "BLock Transfer", part of the AGNES CHIP which can manipulate lines and rectangular parts of graphic images. 3]BOBS See SPRITES 3]BOOT From the expression "to pull yourself up by the bootstraps", it means to start up the computer from scratch. A COLD boot is turning on the computer by the power switch , while a WARM boot is what you do when you press CTRL-A-A. 3]BUS Hardware which connects the CPU, the memory, the co-processors, the disk drives and other devices. 3]CLI Command Line Interface. A way of using the Amiga by using the keyboard. 3]CLIPBOARD A place where you store parts of a file that you CUT or COPY. 3]COLOUR PALETTE The range of colours available to you. 3]COMMAND An instruction you give directly to the computer. 3]CO-PROCESSOR The Amiga has 3 custom Co-processors: Agnes = Animation Co-processor chip which contains the Blitter and the Copper and handles many of the Amiga's graphic functions. Denise = Video Co-processor chip which assists in screen control functions. Paula = Audio Co-processor chip which handles the digital to analog sound conversion for up to four voices, plus many of the input/ output tasks. E.G. such as disk control, mouse and joystick. The ENHANCED CHIP SET allows the co-processors to access 1 Megabyte of CHIP RAM which means greater graphic capabilities. 3]CPU The 68000 chip, which decodes and executes instructions. 3]CURSOR KEYS The four keyboard keys with arrows on them that allow you to move the cursor on the screen. 3]DMA DIRECT MEMORY ACCESS - a way of reading or writing information directly, rather than through CPU intervention. Devices that use this are faster than those that don't. 3]DRAWER Just like a desk drawer. A directory on disk which stores files (programs) in it. 3]DEVICE NAME A unique name given to a device. E.G. DF0: = Disk drive number one. (The internal drive). 3]EXEC Routines of the Operating System which control input/output, interrupt management and multitasking. 3]EXTENDED SELECTION A way of selecting more than one icon at a time. Hold the SHIFT key down while selecting the icons. 3]FILE A file is a collection of data in the form of a program, text (such as a letter typed with a word processor) or a graphics image etc. 3]FONT All the characters that make up a particular typeface, these can be in many different Point sizes. The default system font of the Amiga is Topaz 8. 3]FREEWARE/SHAREWARE/PUBLIC DOMAIN FREEWARE is Public Domain software which the author has made available for everyone to use. SHAREWARE is similar, except that the author wants to keep the copyright and there exists a moral obligation on you to send him a donation if you consistantly use the software. PUBLIC DOMAIN is the same as FREEWARE. 3]GADGET Used in the workbench or custom programs to swap screens, resize screens move windows etc. E.G. Back to Front, Close, Drag, Ghost. 3]GENLOCK A hardware device which combines and synchronises the graphics of the Amiga with those from an external video source. E.G. A video camera or a TV. 3]GIGABYTE A thousand Megabytes. 3]HIGHLIGHT You normally HIGHLIGHT something to show that it is selected. 3]HOLD AND MODIFY (HAM) A way in which all 4096 possible colours can be present on screen simultaneously. 3]ICON A visual representation of some device or object such as a disk, program, drawer, etc. 3]IFF INTERCHANGE FILE FORMAT (or IFF) is a file standard developed by Electronic Arts to assist with the interchange of graphic and sound files among programs, so that you can load graphic images from one program to another. 3]ILBM INTERLEAVED BIT MAP (or ILBM) is One of the formats supported by the IFF standard. 3]INITIALIZE (Also called FORMATTING). Prepares a blank disk so that it can be used by the Amiga. 3]INTERLACE A way of changing a 640X200 screen into a 640X400, it doubles the number of horizontal lines by scanning each second line in two passes of the screen. 3]INTUITION The part of the Operating system which provides for the graphic use of gadgets, menus, requestors and icons. 3]KILOBYTE 1,000 bytes. (one thousand bytes). 3]MEGABYTE  1,000,000 bytes. (one million bytes). 3]MEMORY (FAST, CHIP and SLOW) The first 512K of memory, which is shared by both the CPU and the 3 co-processors is called CHIP RAM. All expansion memory beyond the first 512K is referred to as fast because it is not accessed by the co-processors and so so is not shared by the CPU. With the Enhanced Chip Set an additional 512k can be used as CHIP RAM, givving 1 MEGABYTE of CHIP memory. 3]MENU A list of items to choose from. Usually in the form of menus that are pulled down from the top of the screen with the right mouse button. 3]MIDI MUSICAL INSTRUMENT DIGITAL INTERFACE. This is the standard for connecting electronic instruments digitally. The Amiga does not have a built-in MIDI, but the Audio chip can drive a MIDI interface. 3]MODEM (MOdulator - DEModulator) A device for communicating with other computers over the phone lines. 3]MOUSE Allows you to manipulate the pointer on screen with a minimum of fuss. 3]MULTITASKING The ability to run or operate more than one program or function at a time. The Amiga excels in it's multitasking capabilities. 3]PIXEL (PIcture - ELement) These are the tiny dots that make up the screen. The normal screen has 640 X 200 of them. 3]POINTER The small arrow that moves on the screen when you move the mouse. 3]PORT An outlet on the computer to allow for communication between the computer and external devices. E.G. Joystick Port, Serial Port, Parallel Port. 3]PROTECT TAB The small plastic tab on a disk that can make the disk WRITE PROTECTED, so that it cannot have programs written or erased from. If it's open, the disk is protected. 3]RAM RANDOM ACCESS MEMORY. Memory that is used by the computer to store and manipulate data in any form. 3]RGB MONITOR The 1084s is an RGB analog and digital monitor which is able to display an unlimited number of colours. 3]RESOLUTION The number of horizontal and vertical pixels on screen at any time. Possible combinations are 320X200; 320X400; 640X200; 640X400 and HAM. 3]ROM READ ONLY MEMORY. Memory that cannot be written to, but only read from. ROMS are permanently encoded Integrated Circuits (IC's) 3]ROOT DIRECTORY The main or top directory on a disk. 3]68000/68020 The Amiga uses a 68000 MOTOROLA, the same as the Macintosh and Atari's. 3]SPRITE An example is the pointer. 3]SYNTAX The format or grammar you use for giving instructions to the computer. 3]T.V. MODULATOR Lets the Amiga be used on a U.H.F. television, also has a Composite Video output for monitors or video recorders. 3]VDU / CRT VIDEO DISPLAY UNIT or CATHODE RAY TUBE is the screen you look at, and works by shooting streams of electrons rapidly at the phosphor on the inside surface of the screen. 3]VOLUME NAME The unique name given to a disk. 3]WORKBENCH A disk based operating system for the Amiga, which has all the neccessary information to allow you to use the computer.for the Amiga to work.
