Q & A

What is the primary function of a computer motherboard?

The primary function of a computer motherboard is to serve as the main circuit board that interconnects and assembles various components of the computer system, providing the necessary connections and sockets for these components.

Why is it important to select a compatible motherboard for a computer system?

It is important to select a compatible motherboard to ensure that it supports the microprocessor, main memory (RAM), and other components intended for use in the computer system, thereby guaranteeing optimal performance and functionality.

What is a circuit board and how does it relate to a computer motherboard?

A circuit board, also known as a printed circuit board (PCB), is an electronic component used in almost all electronic devices, including computers. A motherboard is a type of circuit board specifically designed for interconnecting various electronic components within a computer system.

What role does the microprocessor or CPU play in a computer system?

The microprocessor, also known as the Central Processing Unit (CPU), is considered the brain of the computer. It provides the processing power necessary for the computer to perform various operations and is installed into a specific socket on the motherboard.

How is the CPU protected from damage caused by excessive heat?

The CPU is protected from damage caused by excessive heat by mounting a special heatsink on top of the processor chip. The miniature fan of the heatsink provides adequate ventilation and helps to cool down the processor chip.

What is RAM and how is it connected to the motherboard?

RAM, or Random Access Memory, is considered the main memory of the computer and is also called primary memory. It is connected to the motherboard through specific DIMM slots, which firmly hold the RAM modules in place.

What is the purpose of the hard disk in a computer system and how is it connected to the motherboard?

The hard disk serves as the secondary or permanent memory of the computer, storing data even when the computer is powered off. It is connected to the motherboard using a SATA connection cable for data transfer and is also connected to the power supply unit for power.

What are expansion slots and why are they important on a motherboard?

Expansion slots, also known as peripheral component interconnect (PCI) slots, are connection ports on the motherboard where expansion cards can be installed to add additional features and functionality to the computer system, such as graphics processing, sound processing, and network connectivity.

What are the roles of the North Bridge and South Bridge controller chips in a motherboard?

In older motherboards, the North Bridge controller chip connects the processor with the main memory (RAM), while the South Bridge chip provides an interface for connecting various external peripheral input and output devices. In modern motherboards, these functionalities have been integrated into the microprocessor or are handled by a single Platform Controller Hub (PCH) chip.

What are input and output interfaces on a motherboard and what devices do they connect?

Input and output interfaces on a motherboard are connectivity options provided on the rear section of the motherboard. These ports are used to connect various input and output devices such as keyboards, mice, monitors, speakers, printers, and other peripherals.
