|
CPU |
Central Processing Unit The component where all data and instructions are processed. |
|
|
Input Devices |
Devices that allow data such as images, videos, text, sound to be entered into the computer system For example: Microphone, Keyboard, Mouse |
|
|
Output Devices |
Devices that allow data to be communicated from the computer system in a human-friendly form For example: Printer, Monitor, Projector |
|
|
Controller |
Sends and recess signals from all parts of the computer. The controller alsoensures that all process are taking place at the right time in the correctorder. Signals traveled part control bus. |
|
|
ALU |
The component of the CPUwhere data is processed and manipulated. Performs simple calculations on datatemporarily stored in registers, can +, - and compare proces9U9MյP |
|
|
Registers |
Where data is temporarily stored as itfaster to access from registers that from internal memory, as they are accessedso often. |
|
|
Internal Memory |
A fast, temporarystorage space in the CPU. When data from the in the registers are not activelybeing used they are moved to the internal memory. From here data can be writtento the RAM or called back to registers for further processing |
|
|
Buses |
They form simple circuits, which connect every partof the motherboard to each other. Allows data to be transferred to anywhere isthe computer. |
|
|
Cache Memory |
A fast access type of memory which is able to provide CPU with data and instructions at a much faster rate than RAM
Therefore, more Cache memory = better performance |
|
|
Clock Speed |
The speed at which a processor operates The fasterthe clock speed, the faster the fetch-decode-execute cycles are run Thereforefaster clock-speed = More info processed Also it is measuredin Hz |
|
|
Over Clocking |
Increasing clock speed. This causes CPU to use more energy and heat up, which can damage CPU lowering its lifespan |
|
|
Under Clocking |
Setting clock speed to lower than maximum. Therefore, less energy use and produces less heat- saves battery life. |
