∙ 12y agoYour basic computer system consists of....
* Computer case -- The big metal box that everything goes into.
* Power supply -- An electrical converter which converts AC current from the outlet into DC current for the computer components.
* Motherboard -- The main board into which all other components are connected. Mounts in to the back or bottom of the computer case, plugs into the powersupply for power.
* CPU -- Central Processing Unit, the microchip 'brain' of the computer. Plugs into a special socket on the motherboard
* CPU heatsink/fan assembly -- Draws excess heat from the CPU and disperses it into the air. Attaches to the top of the CPU via a clip.
* RAM -- Primary system RAM, temporary data storage for applications that are currently being run. Plugs into special sockets on the motherboard.
* Video card -- Powers the primary output device, the monitor. Enables display devices to be plugged into the computer so that the user interface can be displayed. Plugs into a slot on the motherboard, on some systems it may be integrated into the motherboard.
That's what you need to make a computer power up.... In order to get any work done your computer will need some or all of the following
* Hard disk -- Permanent data storage used to store applications and user data between sessions. Mounts into the computer case and plugs into the power supply for power and into the motherboard via a data cable.
* Optical drive -- CD DVD CDRW drives are essential for installing new applications. Mounts into the computer case, plugs into the power supply for power, and usually uses the same type of data cable as the hard disk.
* Sound card -- Powers the audio sub-system. Plugs into an expansion slot on the motherboard, most modern motherboards have a built-in soundcard.
Note that this list does not include external peripherals such as the keyboard, mouse, monitor, which may or may not fit into someones definition of the phrase "computer system" Nor does it include any software such as the operating system.
