What is the system unit?

System unit in Computer

➢ A boxlike case that houses the computer's main hardware components. ➢ A system unit is the part of a computer that houses the primary devices that perform operations and produce results for complex calculations. ➢ It includes the motherboard, CPU, RAM and other components, as well as the case in which these devices are housed. ➢ The term system unit is generally used to differentiate between the computer itself and its peripheral devices, such as the keyboard, mouse and monitor. ➢ A system unit is also known as a chassis or a tower in layman's terms. ➢ This unit performs the majority of the functions that a computer is required to do. ➢ The system unit holds the system devices that perform calculations as requested from the input device, which can range from a microprocessor to a capacitor or system clock. ➢ Every system device has its own function. ➢ The system unit includes the electronic equipment that interacts simultaneously in order to perform calculations and transfer the results to the corresponding input and output devices.

❖ Memory:

Enables the computer to retain information.

❖ ChipsetA:
