The computer has experienced instant technological developments; experiencing an evolution in size and components. Computers were initially large (often taking up the space of an entire room) but with the passage of time their size reduced and the processing speed reduced from hours to fraction of a micro second. The major components of any computer include:
Central Processing Unit (CPU)
It is the brain of the computer that is responsible for interpreting codes for the operating system, these codes are received from other components, the latest CPU is currently the Intel Core i7.
The second most important part of any computer is the mother board; it is a bridge for connecting all the components.
Random Access Memory
Also known as RAM, it provides temporary memory for the computer. The more the limit of the RAM is, the faster the programs and softwares will run on your computer. RAM is also measured in GB.
Hard Disk Drive
This part stores all the information that we feed into the computer. The memory space of a hard drive is measured in GB (gigabytes).
