16-bit

In computer architecture, 16-bit integers, memory addresses, or other data units are those that are at most 16 bits (2 octets) wide. Also, 16-bit CPU and ALU architectures are those that are based on registers, address buses, or data buses of that size. 16-bit is also a term given to a generation of microcomputers in which 16-bit microprocessors were the norm.

A 16-bit register can store 216 different values. The signed range of integer values that can be stored in 16 bits is -32,768 (-1 × 215) through 32,767 (215 - 1); the unsigned range is 0 through 65,535 (216 - 1). Since 216 is 65,536, a processor with 16-bit memory addresses can directly access 64 KiB of byte-addressable memory.

16-bit architecture

The MIT Whirlwind (c. 1951) was quite possibly the first-ever 16-bit computer. Other early (c. 1965–70) 16-bit computers include the IBM 1130, the HP 2100, the Data General Nova, and the DEC PDP-11. Early (c. 1973–75) multi-chip 16-bit microprocessors include the National Semiconductor IMP-16 and the Western Digital MCP-1600. Early (c. 1975–76) single-chip 16-bit microprocessors include the National Semiconductor PACE, the HP BPC, and the TI TMS9900. Other notable 16-bit processors include the Intel 8086, the Intel 80286, the WDC 65C816, and the Zilog Z8000. The Intel 8088 was program-compatible with the Intel 8086, and was 16-bit in that its registers were 16 bits long and arithmetic instructions, even though its external bus was 8 bits wide.

Bit

A bit, also known as a Shannon, is the basic unit of information in computing and digital communications. A bit can have only one of two values, and may therefore be physically implemented with a two-state device. These values are most commonly represented as either a 0or1. The term bit is a portmanteau of binary digit.

The two values can also be interpreted as logical values (true/false, yes/no), algebraic signs (+/), activation states (on/off), or any other two-valued attribute. The correspondence between these values and the physical states of the underlying storage or device is a matter of convention, and different assignments may be used even within the same device or program. The length of a binary number may be referred to as its bit-length.

In information theory, one bit is typically defined as the uncertainty of a binary random variable that is 0 or 1 with equal probability, or the information that is gained when the value of such a variable becomes known.

In quantum computing, a quantum bit or qubit is a quantum system that can exist in superposition of two classical (i.e., non-quantum) bit values.

  • Education

  • Bearys Institute of Technology, a private technical co-educational college, Mangalore, India
  • Bit (horse)

    A bit is a type of horse tack used in equestrian activities, usually made of metal or a synthetic material, and is placed in the mouth of a horse or other equid and assists a rider in communicating with the animal. It rests on the bars of the mouth in an interdental region where there are no teeth. It is held on a horse's head by means of a bridle and has reins attached for use by a rider.

    Basic types

    Although there are hundreds of design variations, the basic families of bits are defined by the way in which they use or do not use leverage. They include:

  • Direct pressure bits without leverage:
  • Snaffle bit: Uses a bit ring at the bit mouthpiece to apply direct pressure on the bars, tongue and corner of the mouth.
  • Leverage bits:
    • Curb bit: A bit that uses a type of lever called a shank that puts pressure not only on the mouth, but also on the poll and chin groove.
    • Pelham bit: A single curb bit with two sets of reins attached to rings at the mouthpiece and end of the shank. Partly combines snaffle and curb pressure.
    • Kimblewick or Kimberwicke: A hybrid design that uses a slight amount of mild curb leverage on a bit ring by use of set rein placement on the ring.
