Clickipedia Functioning of CPU
The speed of a CPU is measured in Gigahertz (GHz). The Higher the value, faster is the
information processed by the CPU.
Motherboard
Motherboard is also known as the system board or main
circuit board. Many electronic components are either
attached to the motherboard or built into it.
The motherboard contains connectors or slots for attaching
additional boards, CPU, and memory.
Disk Drive Motherboard
A disk drive is used to read from and write to storage disks. Disk drives can be located internally
within the CPU box or in a separate external enclosure. Most disk drives operate in a similar
manner, spinning the disk to read and write data. The Hard Disk Drive (HDD) is the most commonly
used type of disk drive. Other types of disk drives include the Compact Disc (CD) drive, Digital
Versatile Disc (DVD) drive, and Blu-ray Disc (BD) drive.

SMPS
Switched Mode Power Supply (SMPS) is used to control power
supply. It is also known as the power supply unit of the computer.
It takes Alternating Current (AC) from a source, converts it into low
voltage Direct Current (DC), and then supplies it to other parts of the
computer. It has a switching regulator to control the output voltage
and an in-built fan to reduce heat. SMPS
Ports
A port is a slot on the motherboard where you connect various computer components, such
as a keyboard, mouse, monitor, etc. Different types of ports on the motherboard allow you to
connect both internal and external devices. Here are some common ones:
