Want to know what hardware is in your computer? Become a computer pro with our quick guide to these essential components and their roles. Quite simply, computer hardware is the physical components that a computer system requires to function.
It encompasses everything with a circuit board that operates within a PC or laptop;
including the motherboard, graphics card, CPU (Central Processing Unit), ventilation fans, webcam, power supply, and so on. Although the design of hardware differs between desktop PCs and laptops due to their differences in size, the same core components will be found in both. Without hardware, there would be no way of running the essential software that makes computers so useful.
Software is defined as the virtual programs that run on your computer; that is, operating system, internet browser, word-processing documents, etc.
Although a computer can function only when both hardware and software are working together, the speed of a system will largely rely on the hardware used.
When building up a new computer, or simply replacing old parts, you may need to know the specific hardware in your computer. The purpose of this guide is therefore to help you understand the inner-workings of your computer.

The motherboard is in the middle of what makes the PC work. It stays the CPU and is the hub where all the other computer components go. The mother board acts as the brain; allocating power where needed, connecting and connecting to all other components - making it one of the most important pieces of hardware in a computer.
When choosing a motherboard, it is important to consider what hardware holes the motherboard provides. It is important to check how many USB ports, how many distances (USB 2.0, 3.0, 3.1), and which display ports are used (HDMI, DVI, RGB) and how many each. The holes in the motherboard will also help you specify which hardware will work with your computer, such as what type of RAM and graphics card you can use.
Although the motherboard is just one piece of rotation, it is home to one of the most important pieces of hardware: the processor.

The CPU (Central Processing Unit or Processor) is responsible for processing all information in programs run by your computer. ‘Clock speed’, or the speed at which the processor processes information, is measured in gigahertz (GHz). This means that a processor that advertises high GHz ratings will probably work faster than a processor specified in the same product format with the same age.

Random Access Memory, or RAM, hardware available on the motherboard memory. The role of RAM is to temporarily store in-flight information created by programs and to do so in a way that makes this data more accessible. Tasks that require random memory can be; provide graphic design images, edited video or photos, perform multiple tasks with multiple applications open (for example, playing a game on one screen and discussing Discord on another).

A hard drive is a storage device that is responsible for storing permanent and temporary data. This data comes in many different forms, but is actually anything that is stored or stored on a computer: for example, computer programs, family photos, operating system, word processing documents, and more. There are two different types of storage devices: traditional hard disk drive (HDD) and new solid state drives (SSD). Hard disk drives work by writing binary data to rotating magnetic disks called platters that rotate at high speeds, while hard drives store data through chip memory flash flash.

Especially in 3D rendering, the GPU does exactly what its name implies and processes large amounts of explicit data. You will find that your computer graphics card has at least one GPU. Contrary to the basic power of on-board images provided by PC motherboards, dedicated photo cards work with the motherboard with an extended slot to work almost exclusively in explicit delivery. This also means you can upgrade your photo card if you want to get more performance on your PC. Not only this, but modern GPUs carry a wider load of integration beyond just providing, making them an extension to a central processing unit.

The power supply unit, often abbreviated as a PSU, does more than just power your computer. It is the place where power enters your system from an external power source and is supplied to the mother board on the hardware of each component. Not all operating power is equally efficient yet, and without a proper wattage PSU your system will fail to work. A modern computer will usually need a PSU rated between 500W - 850W to power all the hardware, although the size of the PSU will depend entirely on the power consumption of the system. Computers used for more complex tasks such as image processing or games will require more powerful components and thus will need a larger PSU to meet this additional need. Without the right amount of power, the components will not be able to function properly and the computer may have a crash or simply fail to start. It is recommended that you have more power than to cover the use of your system. Not only do you guard against system failures, but you prove yourself in the future against the need for a new PSU as you upgrade to more powerful PC components. Understanding your computer and hardware components can be very helpful when it comes time to upgrade or modify any components, or when building a computer. In the event of a problem with the internal operation of your computer, you will better understand the importance of each component, the need for it to be in good working order and how to solve any problems.
