CPU box is consists of various hardware components present inside it. The hardware inside
the CPU box are Memory and Storage Devices, Main Circuit (Motherboard), Power Controller
(SMPS), Processor, Ports, Cards etc.
The three main components of the CPU are:
• ALU (Arithmetic Logic Unit): Performs mathematical and logical operations.
• CU (Control Unit): Directs all the operations of a processor.
• Memory Unit: Stores data and instructions.
Info Byte
The speed of a CPU is measured in Hertz (Hz). The higher the value, the faster the
information is processed by the CPU.
Motherboard
The motherboard is sometimes called the system board or main
circuit board. It lies inside the CPU, to which all the hardware devices
are connected. Many electronic components are attached to the
motherboard or are built into it.
The motherboard contains the connectors or slots for attaching additional boards, the CPU and
memory. The chips that are attached on the motherboard are known as the ‘Motherboard Chipset’
SMPS
Switched Mode Power Supply (SMPS) is an electric regulator component
that receives electricity from the main power supply and then supplies
appropriate power to the other components of the computer. It takes the
required amount of electricity from mains or UPS and converts the AC
current into DC current with required voltage.
It has a switching regulator which controls the output voltage. It also has an in-built fan to
reduce the heat.
Disk Drive
A disk drive is an internal hardware component of the computer system that is used to read
and write on storage disks. Disk drives can either be located internally within a CPU box or in a
separate box that is external to the CPU box. Most disk drives work in a similar fashion. They spin
the disk for reading and writing data on the disk. The hard disk drive is the most commonly used
disk drive. Some other types of disk drives are Compact Disk (CD) drives, Digital Versatile Disk
(DVD) drives, and Blu-ray Disk (BD) drives.
