Computer Hardware

Whether you are a neophyte or experienced tech person, you have come to the right place to know everything about computer hardware in the UK. In today’s era of technology, anyone living in the UK is far behind the time if they don’t know how a computer works. There are plenty of interesting and knowledgeable facts out there that a regular user of a computer should know. Your computing experience is the product of your interactions with hardware and software.

What is Computer Hardware?

Computer hardware in the UK is a collective term used to describe every physical component of any digital computer. The term hardware specifies the tangible factors of a computing gadget from software, which consists of written guidelines that tell physical components what to do. These hardware gears have been particularly designed over the ages to perform their exclusive functions with different levels of speed, capacity, and ability.

Categories of Computer Hardware

Computer hardware can be broadly classified into internal (installed inside) and external (connected to the outside) components.

Internal Components

These are some common hardware components that you will always find inside the modern computer’s case.

1. Motherboard

2. Central Processing Unit (CPU)

3. Graphics Processing Unit (GPU)

4. Random Access Memory (RAM)

5. Read-Only Memory (ROM)

6. Network Interface Card (NIC)

7. Hard Drive (HDD)

8. Optical Drive

9. Heat Sink

10. Universal Serial Bus Ports (USB)

11. Power Supply Unit

These apparatuses collectively store or process the commands given by the operating system (OS) or any program.

External Components

These components are also termed peripheral components. Such components are usually connected to control the input or output of a computer. These components are monitor, keyboard, speakers, printers, scanners, stylus pens, joysticks, and many others. All these hardware gears are designed to either delivered directives to the software or render the outcomes from their execution.

Now we briefly define some important components of computer hardware.

  1. Motherboard: It is the main circuit board, also known as a main board. The motherboard is the backbone of the computer’s central communication system. It is a point through which all other internal and external components are connected. The motherboard holds components such as RAM, CPU, graphics and Sound card, etc.

  2. CPU: The Central processing unit known as CPU is responsible for all processing of data and turning an input into an output.

  • Monitor: It is a display screen from which a user can see what he/she is doing and how things are going. It can be an external monitor or built-in touchscreen.
  1. RAM: Random-access memory is the main memory of a computer where currently running OS, programs and data are kept. It is much quicker than other kinds of storage. RAM is a volatile memory it means that data only remains there when the computer is on and lost when the system is off.

  2. SSD: It is a type of non-volatile capacity gadget that stores diligent information on solid-state flash memory. SSD comprises a flash controller and NAND. SSDs utilize flash-based memory, which is essentially speedier than conventional mechanical hard disks. Since they’re nonmechanical, SSDs utilize less power, which suggests longer battery life when they’re built into tablet computers.

  3. Graphics card: Dependable for rendering illustrations in a computer and anticipating data onto a screen, a design card points to evacuate the handling strain from the processor or RAM.

  4. Removable drives: Any type of capacity gadget that can be evacuated from a computer where the framework is running, counting USB cards and optical discs, such as compact plates (CDs), Blu-ray discs, and DVDs.

Auxiliary Hardware

Auxiliary computer hardware devices are used for output, input, and data storage, together with an adapter that aids one type of device to communicate with another. They include an onboard complimentary metal-oxide-semiconductors and battery-powered semiconductor chip which regulates hardware settings, time and date system along with data storage.

Hardware vs Software

Hardware denotes the physical aspects of a computing device that are required to store and run the software. The hardware is the conveyance system for the written directives given by the software. The software lets the user relationship with the hardware, ordering it to accomplish tasks.

On the other hand, the software is imperceptible, comprises the OS, programs, and applications that need to be installed on the computer. Nevertheless, virtual keyboards on mobile devices or laptop computers are also taken as software because they are virtual. Wicked software (malware), such as viruses, worms, trojan horses, and spyware can harm software, but hardware is not affected by them.


Conclusively, the software and hardware are inter-depend to enable a computer to generate useful output. Thus, the software must be designed to work suitably with the hardware.
