Consequently, all early computers had a serial ALU that operated on one data bit at a time although they often presented a wider word size to programmers. The first computer to have multiple parallel discrete single-bit ALU circuits was the 1951 Whirlwind I, which employed sixteen such "math units" to enable it to operate on 16-bit words.

The carry flag is set according to this addition, and subtract with carry computes a+not(b)+C, while subtract without carry acts as if the carry bit were set. The result is that the carry bit is set if a≥b, and clear if a<b. The System/360, [3] ARM, POWER/PowerPC, 6502, MSP430, COP8, Am29000, i960, and 88000 processors use this convention.
A collection of computers and other devices connected by communications channels, e.g. by Ethernet or wireless networking. network interface controller. Also LAN card or network card. [6] network on a chip (NOC) A computer network on a single semiconductor chip, connecting processing elements, fixed-function hardware, or even memories and caches.
Computer hardware and software standards are technical standards instituted for compatibility and interoperability between software, systems, platforms and devices. Hardware [ edit ]
Minimal instruction set computer (MISC) is a central processing unit (CPU) architecture, usually in the form of a microprocessor, with a very small number of basic operations and corresponding opcodes, together forming an instruction set. Such sets are commonly stack-based rather than register-based to reduce the size of operand specifiers.
A common example is the Data General Nova, which was a 16-bit design that performed 16-bit math as a series of four 4-bit operations. 4-bits was the word size of a widely available single-chip ALU and thus allowed for inexpensive implementation. Using the definition being applied to the 68000, the Nova would be a 4-bit computer, or 4/16.
