|
Central Processing Unit (CPU)
|
The main component of the computer. It carries out all the processing by fetching and executing instructions.
|
|
|
Clock speed
|
The speed at which the processor carries out instructions, measured in Megahertz (MHz) or Gigahertz (GHz).
|
|
|
Fetch-Execute cycle
|
The process by which programs are run on a computer. The processor repeatedly fetches the instructions of the program from memory and executes them.
|
|
|
Cache
|
High speed memory in the CPU that is used to store a copy of frequently used instructions and data. Faster access speed than main memory. Used to improve CPU performance.
|
|
|
Dual-Core /Quad-Core
|
A CPU that contains multiple processor components (cores) that can operate independently to process more than one task at a time.
|
|
|
Control Unit
|
The control unit works with the CPU to control the flow of data within the system.
|
|
|
Arithmetic and Logic Unit (ALU)
|
a CPU component that performs mathematical calculations on data stored in the register area
|
|
|
Random Access memory (RAM)
|
Main memory of a computer that stores data, applications and the operating system whilst in use. When the power is turned off RAM loses its data.
|
|
|
bus unit
|
a network of circuitry that connects all the other major components together, accepts data, and sends data through the input and output bus sections
|
|
|
clock doubling
|
running the CPU at a multiple of the system clock frequency
|
|
|
decode unit
|
decodes instructions and data and transmits the data to other areas in an understandable format
|
|
|
Dual Independent Bus
|
a bus system architecture in which one bus connects to the main memory and the other connects to the L2 cache
|
|
|
instruction set
|
a set of basic commands that control the processor
|
|
|
overclocking
|
forcing a processor (CPU) to operate at faster than its approved speed
|
|
|
registers
|
small pockets of memory, within the CPU, that are used to temporarily store data which is being processed by the CPU
|
|
|
register unit
|
a CPU component containing many separate, smaller storage units known as registers
|
