Home Computer Parts

Since their invention over two decades ago, personal computers have seen a rapid increase in popularity. It’s now a worldwide statistic that one in four people have a personal computer, and so it’s no wonder that home computer parts have seen a steady incline in popularity too. But what exactly goes in to a computer’s construction and how does each part work? Well here’s a look at the most common computer parts for those new to PCs.

Computer Mouse

These handy little things control the pointer on your computer screen, and they typically consist of a left and a right button. Newer mice will feature a laser guided technology, whereas older models may rely on a small rubber-coated ball. In either instance, a computer mouse can navigate around the operating system and the left button can be clicked to select particular applications. The right button will open a separate menu for an even broader range of options.

Keyboard

Another necessity for most modern PCs, a keyboard is the general source of input when using a computer. It consists of a full set of clickable keys (most commonly in ‘QWERTY’ format), as well as other functional buttons that perform certain actions when pressed. A standard keyboard is good enough for a regular PC, although there are alternate keyboards such as those designed for gaming, or those made for specific applications and processes.

Monitor

Without a computer monitor, it’s impossible to navigate around the operating system of the PC. Monitors come in a range of types and styles – with the most modern ones featuring LEDs and older ones possessing LCD and projection technologies. All Monitors require a separate power source to the central processing unit (CPU), and these power cables can be standard, or the more modern HDMI equivalent.

RAM

Moving on to the internal parts of a computer, the RAM, or random access memory, is in charge of a computer’s speed. The more RAM that a computer has, the more processes that it will be able to undertake without suffering delay. RAM can be replaced or upgraded, although it’s important to find the relevant type and size of RAM (DDR, DDR2 and so on).

Processor

A computer’s processor acts as the heart and brain. Without it, the computer won’t be usable, and with it the PC will be able to operate properly. The processor does exactly what it says on the tin; it processes. By processing information, specific tasks can be carried out within a PC. A processor is also in charge of controlling the flow of electricity to ensure that all components receive the relevant amounts in order to function correctly.
