Topic 1 - Introduction

Question 1

What are the 2 main aspects of a network?

Answer 1

1. Physical Connection (Wires, cables, wireless media).
2. Logical Connection (Data transportation across the physical media).

Question 2

Name 3 basic networking rules.

Answer 2

1. Use the same communication protocols.
2. Ensure data delivery is uncorrupted.
3. Determine the origin and destination of information.

Question 3

What are the 2 main types of network architecture?

Answer 3

1. Client-Server
2. Peer-to-Peer

Question 4

What is the main function of servers in a client-server network?

Answer 4

Servers provide resources and they offer centralized control over network resources like files, printers and authentication.

Question 5

What is a disadvantage of client-server architecture?

Answer 5

Server failure can render a network unusable or result in the loss of network resources.

Question 6

What is a significant advantage of peer-to-peer networks?

Answer 6

Easy to install and configure.

Question 7

What is the typical geographical scope of a LAN?

Answer 7

A small geographical area, such as a single room, building or group of buildings.

Question 8

What is a CAN?

Answer 8

• Campus Area Network
• A computer network of multiple interconnected LANs in a limited geographical area, like a corporation, government agency or university campus.

Question 9

How does a MAN differ from a LAN?

Answer 9

A MAN covers a larger geographical area than a LAN but is smaller than a WAN. It typically interconnects users with computer resources in a city.

Question 10

What is the primary characteristic of a WAN?

Answer 10

A WAN extends over a large geographical distance, typically multiple cities and countries.

Question 11

Provide 1 benefit of computer networks.

Answer 11

Computer networks enable faster, more efficient modes of communication, such as email and video conferencing.

Question 12

What is a disadvantage of peer-to-peer networks?

Answer 12

Network security applies only to a single resource at a time in peer-to-peer networks.

Question 13

Name 1 advantage of client-server architecture.

Answer 13

Centralized user accounts, security and access-controls to simplify network administration is an advantage.

Question 14

Why might an organization choose to implement a Campus Area Network (CAN)?

Answer 14

A CAN is suitable for connecting multiple buildings in a campus, providing efficient communication within a large organization or educational institution.

Question 15

What is the primary purpose of a Wide Area Network (WAN)?

Answer 15

A WAN facilitates communication and resource sharing over a vast geographical area, connecting multiple LANs or MANs across cities and countries.

Question 16

Name 1 benefit of having centralized control in a client-server network.

Answer 16

Centralized control allows for more efficient access to network resources and simplifies network administration.

Question 17

How do computers provide backup and recovery support?

Answer 17

Computer networks facilitate data backup and recovery by implementing redundancy, ensuring data is no lost in case of failures.
