The System Unit is one of a computer's four main hardware components. It is normally a rectangular container that houses other important hardware components. Random Access Memory (RAM), Compact Disc-Read Only Memory (CD-ROM), Hard disk drive, Motherboard, Fan, Processor or Central Processing Unit (CPU), Power Supply, and Expansion cards are some of the components in the system unit. The system unit, also known as a "tower" or "chassis," is the main part of a desktop computer.

System Unit

Motherboard- It is the main circuit board of the computer. It is a thin plate that houses the processor, memory, hard drive and optical drive connectors, video and audio expansion cards, and connections to your computer's ports (such as USB ports). Any component of the machine is connected to the motherboard, either directly or indirectly.​

Motherboard

The central processing unit (CPU), also known as a processor, is found on the motherboard inside the computer case. It is often referred to as the computer's brain, and its role is to execute commands.​

CPU

Random Access Memory - The primary memory of a computer system's main purpose is to temporarily store data. It enables the CPU to quickly access data due to the fact that data is accessed at random (in no specific order). Because of its ability to allow random access to data, it also speeds up the computer's operations.

RAM

Hard disk drive - Your applications, documents, and other files are stored on the hard drive. The data is saved even though you turn off the device or unplug it because the hard drive is long-term storage.​

Hard Disk Drive

Power Supply Unit - A computer's power supply unit transforms power from a wall outlet to the form of power needed by the computer. It supplies power to the motherboard and other components through cables.

Power Supply Unit

Expansion Cards - It is a printed circuit board that can be inserted into an electrical connector, or expansion slot on a computer's motherboard ​

Expansion Card

Computer Fan - Another part within the computer system unit is a fan. The fan also circulates cool air through the heat sinks of different devices, including processors and chipsets.

Computer Fan

Computer Data Cables - The data cable connects the hard drive to the motherboard and vice versa. SATA and IDE data cables are the two most common types of data cables.

Remember

• It is important to keep in mind the different safety measures before installing computer hardware and software components. Following safety procedures protects us from injuries such as electrical hazards, heat, chemicals, and infection, for job-related occupational safety and health purposes.

• Understanding the components of a system unit and its functions is vital in order to find out what the problem is if the computer stops working. You must also be familiar with electronic devices in order to understand basic machine troubleshooting.
