16-bit
From Free net encyclopedia
Prominent 16-bit processors include the Intel 8086, Motorola 68000, Intel 80286 and the WDC 65C816. The Motorola 68000 was 16-bit in that its data buses were 16 bits long; however, it was 32-bit in that the general purpose registers were 32 bits long and most arithmetic instructions supported 32-bit arithmetic, and 24-bit in that addresses were 24 bits long.
A 16-bit integer can store <math>2^{16}</math> (or 65536) unique values. In an unsigned representation, these values are the integers between 0 and 65535; using two's complement, possible values range from −32768 to 32767.
16-bit processors have been almost entirely supplanted in the personal computer industry, but remain in use in a wide variety of embedded applications.de:16-Bit-Architektur it:16 bit es:16 bits he:16 ביט pl:Architektura 16-bitowa sk:16-bitový zh:16位元
