10 Basic Things You Should Know About Hardware


The essential components of a computer are referred to as computer hardware. It alludes to computer systems, particularly those containing a central processing unit. Computer technicians should be familiar with the fundamental parts of computer hardware, including the motherboard, power supply, keyboard, mouse, and monitor, and how to operate each component from a hardware shop near me. 

The physical parts of a computer are referred to as computer hardware. Desktop, laptop, and tablet computers are examples of personal computers (PCs), electronic gadgets that process information using microchips. Since a computer consists of numerous hardware parts, they must cooperate and rely on one another in order to operate effectively. The fundamental parts of computer hardware Dubai include the following: 

  • CPU (Central Processing Unit)  
  • Motherboard 
  • RAM (Random Access Memory) 
  • Hard disc drive/solid-state drive (HDD/SSD) 
  • PSU (Power Supply Unit) 
  • GPU (Graphics Processing Unit) 
  • Tower/Case Computer 
  • Computer Display¬†
  • CD/Blu-ray Optical Drive


The CPU interacts with the other parts of a personal computer and manages the computing processes. Because of its intricate design, a computer’s CPU could be one of the most challenging components. A computer technician may begin by inspecting the fan and clearing out any dust or dirt from the computer’s interior if the CPU is having problems. Checking that power supply cables function is another task a computer technician might perform. A CPU cannot operate correctly without a signal from the power source. 


All other components are connected to and supported by the motherboard, which also serves as a channel for power, data, and connections to peripherals like a mouse or printer. It determines, among other things, how data is transferred and the kind of screen or monitor to use. The CPU, RAM, and auxiliary storage components like hard drives are all housed within. 

Random Access Memory (RAM)

When a user runs a computer application, data is temporarily stored in RAM while the program is using it. A technician may be able to determine the type of RAM in a computer, repair it if it is damaged, and find issues with data copying between locations in memory. 

Array Port For Video Graphics 

A video input commonly used on PC monitors is called a video graphics array (VGA) port. Verifying that there isn’t a loose connection, a defective cable, or a broken display is one step in troubleshooting a VGA port. Compressed air can also be sprayed inside the VGA port by a computer expert to ensure it’s dust-free. 

Power Source 

All of a computer system’s parts are powered by a power source. Typically, a power cord is used to connect a computer tower to an electrical outlet. A technician can diagnose the power supply by turning off the computer, unplugging and separating the power supply, or trying a different cord or socket. 

Coolant Fan 

A computer’s system to prevent overheating uses cooling fans. Many computers contain more than one cooling fan to aid customers who use their computers intensively, such as when streaming video or playing games. A computer expert might need to repair the cooling fan if a user detects their computer overheating. The blades may be examined for damage and cleared of foreign objects. A technician’s standard method of troubleshooting may involve replacing computer fans. 

Hard Drive 

On a computer system, files, programs, and other types of data are stored on hard drives, which are data storage devices. They use hard discs, which are magnetically coated discs used to store digital versions of information. A computer technician can suspect a corrupt hard disc when a hard drive dies. They might apply data recovery software or swap out the hard drive to fix the computer. 


A computer monitor is a piece of technology that shows the user what programs are currently running on their computer. Some computer technicians may put on anti-static gloves when handling computer monitors to reduce static electricity. They could also try unplugging the monitor from the computer and using a different power cord to diagnose the problem. 


This device uses ink to create copies of text or images on paper. Computer technicians may be adept at diagnosing issues across various brands and printers, including popular ones like laser or inkjet from hardware shop Dubai. Printers can be serviced by computer technicians, who may also check if the equipment is receiving electricity. Additionally, they might verify if the paper tray is loaded and prepared for printing. Any toner or ink cartridges may be changed out or refilled by technicians. 

Laptop Mouse 

An input device is used to manipulate a computer monitor’s cursor; a computer mouse can be wired or wireless. A wireless computer mouse has no physical connection to a computer system, while a USB port on a computer is connected by a cord to a wired computer mouse. Instead, a wireless mouse uses Bluetooth technology to interact with an adapter that is often plugged into a free USB port and powered by its batteries. 


Computer specifications are a general term for the type of installed hardware. You are not required to be skilled in computer construction. Instead, knowing what the hardware performs will enable you to solve problems. The mouse, keyboard, and monitor are the main focal points. Therefore, even if your computer has everything, it will be useless without peripherals. A piece of physical hardware is all that a peripheral is. It enables a user to communicate with a computer.
