Computer hardware components are the electronic and mechanical parts. Typically, the components are housed in a case. Many of the components are connected to the main circuit board of the computer, called the motherboard. The power supply provides power for most of the components. Various input devices, such as the keyboard and the mouse, and output devices such as the monitor are attached through the connectors on the case.

The major hardware components of a computer system are:

Computer case: This is the enclosure that holds all the computer components. The computer case needs to be spacious enough to allow for air ventilation to prevent overheating. It also needs to be reasonably sturdy and able to hold the components together securely.Computer motherboard: Also called the main board, the motherboard is the backbone of a computer. It connects all the computer components, directly or via special cables: the central processing unit (CPU), hard drives, memory, graphics card, and so on. Choose the motherboard that has all the slots and ports you need.

Central processing unit (CPU): This is the brains of a computer. Generally, computers with multiple CPU cores can do more in a shorter period of time. The two major manufacturers of CPUs are Intel and AMD. Demanding tasks such as video editing, photo editing, or gaming, require a powerful CPU.

Random Access Memory (RAM): Often called memory or RAM for short. The more of it your computer has, the faster it will be. Basically, RAM allows you to execute multiple programmes simultaneously without a noticeable lag or long loading times.

Graphics card: Also called Graphics processing unit (GPU) or video card, graphics card is what enables your computer to produce excellent visuals. This computer component enables the computer to display images on the monitor and typically plugs into the motherboard. Graphics cards are manufactured by either NVIDIA or Radeon.

Hard drives: This is where all you do on your computer goes when you press the save button. A hard drive is the storage unit or the permanent memory of your machine (permanent, because it does not get erased when the computer is shut down). When shopping for a data storage drive, you need to decide whether you want to get a traditional hard disk drive (HDD) or a solid state drive (SSD).

Regardless of whether you want to build your own budget or gaming computer, or to upgrade your existing desktop, you will find the right computer hardware components right here on Bob Shop.
