Bus that transmits data at very high speeds; designed to support video and 3D graphics. An AGP bus is twice as fast as a PCI bus and supports video and 3D graphics.
You are watching: ________ is the binary code most widely used on microcomputers.
Part of the CPU that performs arithmetic operations and logical operations and controls the speed of those operations. Arithmetic operations are the fundmental math operations: addition, subtraction, multiplication, and division. Logical operations are comparisons such as “equal to,” “greater than,” or “less than.”
Binary code used on microcomputers. Besides having more conventional characters, the Extended ASCII version includes such characters as math symbols and Greek letters. Important because: ASCII is the binary code most widely used in microcomputers.
A two-state system used for data representation in computers; has only two digits-0 and 1. Important because: in the computer, 0 can be represented by electrical current being off and 1 by the current being on. All data and program instructions that go into the computer are represented in terms of these binary numbers.
Short for “binary digit,” which is either a 0 or a 1 in the binary system of data representation in computer systems. Important because: the bit is the fundamental element of all data and information processed and stored in a computer system.
Also called bus line; electrical data roadway through which bits are transmitted within the CPU and between the CPU and other components of the motherboard. Important because: a bus resembles a multilane highway: the more lanes it has, the faster the bits can be transferred.
Group of 8 bits. Important because: a byte represents one character, digit, or other value. It is the basic unit used to measure the storage capacity of main memory and secondary storage devices (kilobytes and megabytes).
Special high-speed memory area on a chip that the CPU can access quickly. It temporarily stores instructions and data that the processor is likely to use frequently. Cache speeds up processing.
Also called a microchip; consists of millions of micro-miniature integrated electronic circuits printed on a tiny piece of silicon. Silicon is an element widely found in sand that has desirable electrical (or “semiconducting”) properties. Important because: made small computers possible.
Groups of interconnected chips on the motherboard that control the flow of information between the microprocessor and other system components connected to the motherboard. Important because: the chipset determines what types of processors, memory, and video-card ports will work on the same motherboard. It also establishes the types of multimedia, storage, network, and other hardware the motherboard supports.
The processor; it follows the instructions of the software (program) to manipulate data into information. The CPU consists of two parts – (1) the control unit and (2) the arithmetic/logic unit (ALU), both of which contain registers, or high-speed storage areas. All are linked by a kind of electronic “roadway” called a bus. Important because: the CPU is the “brain” of the computer.
Network standard for linking all devices in a local area network (LAN). Important because: It”s commonly used to connect microprocomputers, cable modems, and printers. (To use Ethernet, the computer must have an Ethernet network interface card, and special Ethernet cables are required.
Secondary storage medium; thin but rigid metal, glass, or ceramic platter covered with a substance that allows data to be stored in the form of magnetized spots. Hard disks are tightly sealed within an enclosed hard-disk-drive unit to prevent any foreign matter from getting inside. Data may be recorded on both sides of the disk platters.
