Q & A

What is the purpose of the disclaimer at the beginning of the lesson?

The disclaimer clarifies that the author does not claim ownership of the materials used in the lesson, which belong to their original creators. It also specifies that these materials are used solely for educational purposes.

What is the main objective of the lesson on installing and configuring computer systems?

The main objective is for at least 80% of the students to be able to describe the function of the motherboard, identify the different parts of motherboards, and understand their functions.

What is the significance of the motherboard in a computer system?

The motherboard is considered the backbone or spine of a computer because all other components are either directly or indirectly connected to it.

What are some alternative names for a motherboard?

A motherboard can also be referred to as the main board, system board, planar board, or logic board.

What are the key components that a motherboard holds in a computer system?

A motherboard holds crucial electronic components such as the central processing unit (CPU) and memory, and provides connectors for peripherals.

What is the function of the back panel on a motherboard?

The back panel allows for the connection of external devices like monitors, speakers, keyboards, and mice.

What is the difference between a serial port and a parallel port?

A serial port is intended for serial type mice and older cameras, while a parallel port, also known as a printer port, is for older model printers and has 25 bits.

What does a USB port provide and what types of devices can it connect?

A USB port provides a high-speed serial interface used with almost all devices, including printers, pen drives, cell phones, and other portable computer attachments.

What is the purpose of the PS2 port on a motherboard?

The PS2 port is used for low-speed serial connections and is commonly dedicated to keyboards and mice.

Why is the power port considered the most important port on a motherboard?

The power port connects the computer to the main source of electricity, making it functional.

What is the function of the audio port on a motherboard?

The audio port is intended for plugging in speakers or a headset, and it is also used for microphone connections.

What does LAN stand for and how is it used in computer systems?

LAN stands for Local Area Network. It is a physical interface often used for terminating twisted pair type cables to connect computers onto local area networks, specifically using Ethernet.

What is the significance of the RJ45 connector in networking?

The RJ45 connector is a standardized networking interface used for Ethernet networks, providing a way to connect devices within a local area network.
