A case that contains electronic components of the computer used to process data
Sometimes called a System board, is the main circuit board of the system unit
Is a small piece of semi-conducting material, usually silicon, on which integrated circuts are etched
Central Processing Unit interprets and carries out the basic instructions that operate a computer
Is a Chip with two or more seperate processor cores. Two common multi-core processors are dual-core and quad-core
Component of a processor that directs and coordinates most of the operations in the computer.
Arithmetic and Logic Unit - does all mathematical calculations and makes all logical decisions
The system clock is an important part of the processor that keeps time for the computer. Much like the heart in a human body, the system clock helps coordinate the actions the computer takes. The faster the clock, the more the system can do in a period of time.
The pace at which the computer processes information is regulated by the system clock. Modern system clocks tick at a rate of 1-4 gigahertz (billions of ticks each second).
A system in which numbers are represented using only the digits 0 and 1.
In binary (computer language), a bit represents a zero or one.
A byte is another word for character; generally represented by 8 bits.
System or process by which the products or results of learning are stored for future use
Data that will be lost when the computer or device is not powered.
Memory that is not lost when the computer is turned off. An example is the read-only memory that contains start-up instructions and other critical information.
Random Access Memory (RAM) is volatile memory that is used by the computer to store instructions for running programs and any data currently needed by those programs. It is the main memory of a computer and is the one most commonly referenced when reading a computer's specs.
ROM is short for read only memory and indicates that the memory in question is non-volatile and cannot be changed under normal use. ROM memory is fixed at the time of its production and can only be read from and seldom, if ever, changed. In certain cases, certain types of ROM may be re-flashed, but this is not a common task. For this reason, the instructions stored on a ROM chip such as a computer's BIOS are often called firmware.
small circuit board with RAM chips on both sides
slots on the motherboard that hold memory module
(computer science) RAM memory that is set aside as a specialized buffer storage that is continually updated
Cache that helps speed the processes of a computer by storing frequently used instructions and data
built into the processor
separate chip from CPU containing more memory than level 1 cache, but is slightly slower
(Read only memory) a chip on the motherboard that is prerecorded with and permanently stores the set of instructions that the computer uses when you turn in on; permanent
nonvolatile storage that can be electrically erased and programmed anew
Complementary Metal Oxide Semiconductor
the amount of time it takes the processor to read data, instructions, and information from memory
1 billionth of a second
is a socket on the motherboard that can hold an adapter card
A printed circuit board that you can insert into a computer to give it added capabilities
device that can be attached to or used with a computer
converts electronic information into the text, images, movies, and animations that are displayed on a computer screen.
enhances the sound-generating capabilities of a personal computer
A board that plugs into your computer to allow it to display graphics.
Is a removable flash memory device
(computer science) computer circuit consisting of the hardware and associated circuitry that links one device with another (especially a computer and a hard disk drive or other peripherals)
Short for Universal Serial Bus, an external bus standard that supports data transfer rates of 12 Mbps. A single USB port can be used to connect up to 127 peripheral devices, such as mice, modems, and keyboards
similar to a USB port that can connect multiple types of devices
allows you to plug in printers and diskdrives
device used to connect multiple external devices to a laptop computer
A means of converting a laptop computer to a desktop computer.
A collection of wires through which data is transmitted from one part of a computer to another.. The internal bus that connects all the internal computer components to the CPU and main memory. Every bus has a clock speed measured in MHz. A fast bus allows data to be transferred faster, which makes applications run faster
part of the motherboard and connects to the processor of the main memory
