Free Bachelor of Science in Computer Science : Network Fundamentals Questions and Answers

Question 1

When is it necessary for a computer to possess an IP address?

Accepted Answer

Connecting to a Wi-Fi hotspot

Answer

An IP (Internet Protocol) address is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. To connect to a Wi-Fi hotspot, which is part of a network, a computer needs an IP address to send and receive data packets. Playing media from a hard drive is a local operation and does not require network connectivity or an IP address.

Question 2

What is another term that can refer to a home computer network

Accepted Answer

LAN

Answer

A home computer network is commonly referred to as a Local Area Network (LAN). A LAN connects devices within a limited geographical area, such as a home, office building, or school. This allows devices like computers, printers, and smart devices to share resources and communicate with each other efficiently.

Question 3

What do peripherals primarily encompass?

Accepted Answer

devices connected to a computer system to add functionality.

Answer

Peripherals are external devices that connect to a computer system to expand its capabilities or add specific functionalities. Examples include keyboards, mice, printers, scanners, and external hard drives. They are not essential for the core operation of the computer but enhance its utility and user interaction, making the system more versatile.

Question 4

What is the simplest device in a computer network that solely connects computers and lacks any additional functions?

Accepted Answer

Hub

Answer

A hub is the simplest device in a computer network used to connect multiple devices. It operates by broadcasting all incoming data packets to every connected port, without distinguishing between recipients. This makes it less efficient and less secure than a switch, which learns device addresses and forwards data only to the intended destination.

Question 5

Which of the following pairs share the most similarities?

Accepted Answer

Hub & Switch

Answer

Hubs and switches share the most similarities as they both serve to connect multiple devices within a local area network (LAN). Both act as central connection points, allowing computers to communicate. However, a switch is a more intelligent version of a hub, as it can direct data to specific devices, whereas a hub simply broadcasts data to all connected devices.
