3D Graphics      3D graphics is now the norm with depth and with upto date graphics
                 chips can produce textured graphics for extra realism. Uses X/Y/Z
                 co-ordinates to produce vector graphics with colour, light sources
                 and texturing to produce life-like graphics.

8008             Intel processor introduced in April 1972.
 
8086             First 16 bit processor in x86 family, in 1978, made by Intel with 16 bit address bus
                 and 8 16-bit registers and access to 1MB of memory.

8088             New processor introducted in 1974 which was similar to the 8086 but had an 8 bit address bus. 
                 It was the first Intel processor to be used in the IBM PC.

80286            Replacement 16 bit Intel processor. Support for upto 1Mb of
                 RAM in most cases.

80386            First 32 bit Intel processor with Real and Protected modes.
                 Allowed access to Extended and Expanded RAM beyond the first
                 1Mb of earlier processors.

								 
80486            Replacement 32 bit Intel processor upto 100MHz. 
                 Some had caches, and dual-clock capabilities.

								 
8 Bit            This refers to the number of binary digits (0 or 1) the processor
                 can refer to at once. 8 bit numbers range from 0-255 (unsigned) or
                 -127 to 128 (signed). 8 bit computers include: ZX81, ZX Spectrum,
                 Commodore 64, BBC A/B etc.

16 bit           16 bit numbers can range from 0 to 65536 (64K) or -65535 to 65536. Typical
                 16 computers include Atari ST, Commodore Amiga 500, IBM AT compatible.



32 bit           32 bit numbers can range from 0 to 4.29 GB. Most modern desktop computers
                 are 32 bit including Pentium PCs, Apple Macs, Commodore Amiga 1200/4000.

                
64 bit           64 bit numbers can range from 0 to 18TB. Only very high end workstations and
                 servers use 64 bit computers including Itanium PCs, Athlon 64, Intel Core and 
                 UltraSparc unix computers.
