The motherboard is the primary hardware component in a computer that serves as the central hub connecting and managing other essential components like the CPU, RAM, and graphics card. It contains the computer's circuitry and chipset that directs data traffic and communication between all attached components. The motherboard also houses the BIOS that controls the boot process and loads the operating system. It provides ports and connectors for attaching peripheral devices to increase the computer's functionality.

1. An Overview of the Function of a Motherboard
This article provides an overview of the critical function of a motherboard in a computer system.
The function of a motherboard is indispensable for the operation of any computer system. Motherboards are the
primary hardware component on a computer, and perform a number of critical tasks. Following is an overview of the
function of the motherboard.
Components' Hub
A primary function of the motherboard is to serve as the base upon which a computer’s components are built. The
motherboard is, in essence, a hub that houses a number of essential components such as the Central Processing Unit
(CPU), system memory (RAM) and graphics card. The typical computer is designed with these components built onto
the motherboard.
Computer Circuitry
The motherboard is the computer’s main circuit board, bearing all the basic circuitry and components that are required
for the computer to function. It has electrical pathways called buses, which enable data to be relayed to the different
computer components as well as between them.
Data Traffic
The motherboard serves as a communications hub for all of the components that are attached to it directly or
indirectly. It is responsible for managing the traffic of information within the computer system, which it does by
means of the motherboard chipset. The function of the motherboard chipset is to direct the flow of data that the
computer components require or acquire.

2. BIOS
The motherboard has a built-in Read Only Memory (ROM), which is separate from the PC’s RAM and which
contains the computer’s Basic Input/Output System (BIOS). A key function of the BIOS is to manage the boot-up
process when you power your computer on, and load your operating system.
Peripherals
The motherboard allows for the use of external components and devices, which greatly increases the versatility of a
computer system. These include printers, keyboard devices, audio jacks, external hard drives and game controllers.
These peripherals can be connected to the computer by plugging them directly into the motherboard by means of
external ports, sockets and connectors, which are built into it.
Note: motherboards are also used in a variety of electronic devices, such as televisions, which must perform
complicated processes to operate. They fulfill similar functions in these devices.

3. How much is 1 byte, 1KB, 1MB, 1GB, 1TB , 1PB, 1EB, 1ZB, 1YB
1 byte vs 1KB vs 1MB vs 1GB vs 1TB vs 1PB vs 1EB vs 1ZB vs 1YB
The basic unit used in computer data storage is called a bit . 8 Bits is equal to 1 Byte .
Bit : A Bit is a value of either a 0 or 1.
Byte : 1 Byte = 8 Bits
Kilobyte (KB) : 1 KB = 8,192 Bits ,
1 kB = 1,024 Bytes
Megabyte (MB) 1MB =1024 KB
Gigabyte (GB) 1GB = 1024 MB
Terabyte (TB) 1TB = 1024 GB
Petabyte (PB) 1PB = 1024 TB
Exabyte (EB) 1EB = 1024 PB
Zettabyte (ZB) 1ZB = 1024 EB
