8-bit

8-bit CPUs normally use an 8-bit data bus and a 16-bit address bus which means that their address space is limited to 64 kilobytes; this is not a "natural law", however, and thus there are exceptions.

The first widely adopted 8-bit microprocessor was the Intel 8080, being used in many hobbyist computers of the late 1970s and early 1980s, often running the CP/M operating system. The Zilog Z80 (compatible with the 8080) and the Motorola 6800 were also used in similar computers. The Z80 and the MOS Technology 6502 8-bit CPUs were widely used in home computers and game consoles of the 70s and 80s. Many 8-bit CPUs or microcontrollers are the basis of today's ubiquitous embedded systems.

16-bit: Prominent 16-bit processors include the Intel 8086, Motorola M68000, Intel 80286 and the WDC 65C816....

Address space: In computing terms, a memory address identifies a physical location in computer memory, somewhat similar to a street address in a town. The address points to the location where data is stored, just like your address points to where you live....

Kilobyte: A kilobyte (derived from the SI prefix kilo-) is a unit of information or computer storage equal to either 1024 or 1000 bytes. It is commonly abbreviated KB, kB, Kbyte, kbyte, or very informally, K or k....
