The three main components of the CPU are:
                                                                                                      Memory Unit
                      Arithmetic Logic Unit (ALU): It performs all mathematical and logical
                     operations.
                      Control Unit (CU): It manages and directs the processor’s operations.           Control Unit
                      Memory Unit (MU): It stores data and instructions.

                                                                                                          ALU

                    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.

                  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:
