This is the biggest piece of hardware in the system. This is where various other essential components connect onto it, such as CPU, Ram, Hard Disk drive, etc, to it. Modern mid-range mainboard usually comes with add-on component such LAN port, sound card and graphics card. As other hardware connects to the mainboard, it is important to ensure that the mainboard purchased is of high caliber and has at least the add-on component as stated in the paragraph above Central Processing Unit (CPU) This is one of the computer hardware that determines the speed of the whole system. The other determining hardware are the RAM and Hard Disk Drive. Single Core CPUs are almost obsolete and are much slower compared to their Dual Core / Quad Core counterparts. Usually a numeric figure is stated and that is the clock frequency, commonly known as the speed of the CPU. Usually the higher the clock frequency, the faster your data can be processed.
Ram Known as Random Access Memory, are memory chips where data are temporary stored. By storing the data on RAMs, the CPU is able to process the data in a shorter period which leads faster execution of the instructions and tasks assigned to the computer. Usually a numeric figure (in Gb) is stated and that is the physical size of data the RAM is able to store. Hard Disk Drive This computer hardware keeps all data permanently, unlike the RAM which will erase data if the computer is shut down. Comes in sizes of 2.5" (for laptop) and 3.5" (for Desktop) Usually a numeric figure (in Gb) is stated and comes in various capacity |
