AGA = Advanced Graphic Architecture The "Custom Chips" 32 bits that are in the 1200 and 4000 and CD32. Allow (among other things) a bigger "Chip" memory  (2 Mb) display in 256 colors, the  HAM update to 262000 colors (HAM8), Hi-resolutions display modes like PAL 1280*512,  blitter is fully 32 bits, enhanced Sprites , etc ... Compatible with PAL/NTSC/VGA/MultiSynchrone  monitors or TV

AHI Amiga Driver for audio card

AMIGA see that page in french

AmigaDos, Dos Library that manage files, directories,etc ... Similar to MS-DOS 

ARexx System Script language on Amiga Allow programs intercommunicating and interfacing. Similar to Rexx 

AROS = Amiga Research OS Project  whose goal is to rewrite AmigaOS 3.1 in  C for all the kind of computers (mainly Linux and IBM PC native ). 

Assign Amiga Shell command that allow to create logical names for drives or directory. Example: assign FONTS: wb3.1:fonts 

Bitplanes  Pixels that are displayed on screen come from binary data called a "bit planes" it's a black and white image where each bit represent a black (0) or white (1) pixel.
To obtain a color image each bit plan lay on other one. So 2 bitplanes give 2 bits that can code 4 colors
00 ( color 0)      01 ( color 1)    10 (color 2)   11(color 3)
The same apply  for 3 bitplans ( 8 colors) 4 bitplans (16 colors) ...... 8 bitplans (256 colors)
Alle those bitplanes cans scroll freely and fastly independantly and be used as Dual Playfield.

Blitter = Block Image Transferrer One of the custom chip It's a graphic coprocessor like on modern graphic cards.
Can display/merge image on screen, draw lines, fill surfaces.

Blit a blitter opérations.

BOBs Blitter object Graphical objetc that apppear in front of the screen background. Create by operations of copy / masking / inserting of the Blitter. It is made with binary datas from the screen 

Bootblock Track (0 and 1) that allow floppy to be bootables (made with "c:install df0:".
 Those track always got a standard 
 format (ie are readable) even if the floppy got a protection. May contain boot virus. 

 C: Directory thta contain  the Shell  commands  . It's in SYS:/C. Similar to C:\DOS and not to C:\ from PC. See also SYS: 

C2P "Chunky To Planes" format conversion software Typically convert a PC or Mac Screen to Amiga AGA native 

Caligari24 3D Amiga Software that have been adapted to PC with the name

 CD0 : Standard name for a CD-ROM 

CD32 Amiga Game console 68020 + AGA + System 3.1 The first ever 32 bits + CD

CDTV Home Amiga 68000 + OCS with CD-ROM  intended to converge with black
 boxes like Hi-Fi or VCR 

Chip is the memory that is used by the processor AND the "Custom  Chips" of an Amiga for the graphics, sound and partillay for gadgets, windows, DMA drives buffers,
 floppy buffers, etc ... 

Chunky For that  kind of pixels the data come from sequential data block in memory
 So 1 pixel in 256 colors = 1 byte, 2 pixels 16 colors
 = 1 bytes. 

 Cinema4D An Amiga 3D Software that have been adapted on PC. 

 ClassAct Library that allow to fully configure aspects and GUI. Only work for software that have been
written with it so very similar to MUI. 

Copper An other graphical coprocessor that allow to change resolutions,size,scroll/deform screen and change colors during display. This coprocessor has programs called CopperLists associed to a Screen. 

Custom Chips Chips that have been created by the Commodore Amiga Team
 and that are on the motherboard of True Amigas. They enhance display, scrollings and DMA,audio, video and animating erformances. Customs Chips are the Blitter, Copper, Paula, Denise,
 the two CIA, Super Buster, Aikiko, Gary etc...

Screen Amiga concept of hardware windows that can be of different resolutions on a single monitor.
 Screens can be in front of each other, can be scroll down, or be bigger than screen and then folow the mouse by scrolling . It's similar to Xwindow display but the custom chips allow screenS to be on a single monitor.

ECS = Enhanced Chip Set The old "Custom Chips" that are inside the Amigas 600 and some recents A 2000 and A500 Alow among other things a bigger "Chip"  (2 Mb) and higger resolution modes like PAL 1280*512, etc ... 

EGCS a more recent version of GCC that don't come from the GNU team but from Linux community. 

Interlaced Some Screen resolution are interlaced like TV notably the PAL and NTSC ones. When interlaced display is donned in to time : first frame with odd lines, second frame with even lines.
As the global refresh rate fall down it flicker (50hz  become 25 Hz)

ENV-ARC: The directory SYS:Prefs/Env-Archive contain the backup of the system and applications settings and default icons (for files that don't have a .info) . Thta directory is copied to RAM: at boot in the directory ENV: 

Exec Library contain the kernel of Amiga OS : multitasking, memory,etc...  Exec has been written by Carl Sassenrath author of Rebol.

Extra-halfbrite False 64 colors graphical mode. Same as 32 color mode with colors 32 -63 that are darker than 32 firsts one.
See Alcatraz MegaDemo II 

Fast is the memory usable ONLY by the processor so it's faster. Because memory access aren't shared with "Custom Chips" 

Fellow Amiga emulator better for games

It was black and red blinking with esoterics messages appearing wen old Amigas crash.

HAM = Hold And Modify Amiga image format that are hardware packed (6 bits per pixel in memory give 12 bits colors on screen ) , in 4096 colors 

HAM8 same as HAM but on  AGA  chips with more than  262 000 colors  (8 bits per pixel in memory give 18 bits colors on screen )

 ..) and some drivers (scsi.device, 2nd.scsi.device,etc...)

Slow Is a part of memory that can't be used by the old version of the "Custom Chips" limited to 512 Kb but with bus acces shared with the CPU. Older  Amiga OS think it was fast Memory  but no it wasn't = True fast mem don't share memory access. 

 Software Failure A New name for the "Guru meditations"

 Windows from PC and the Finder from Macs 

YAM, AmigaMail. Similar to MsMail 

Z3 fast is memory that is in an extension card plugged in a Zorro Bus Z3. As the Amiga motherBoard can't accept more than 16Mb it was (a long time ago) the only way to extend memory beyond 16 Mb
