3.3 - Networking Characteristics

Question 1

What is an IP Address?

Answer 1

Unique identifier for computer systems on networks.

Question 2

What is a Default Gateway?

Answer 2

Bridge between computers and networks for data transfer.

Question 3

What is a Router?

Answer 3

Forwards messages between networks to connect to multiple devices.

Question 4

What is a Network?

Answer 4

Connections between devices which enable resources and data to be shared.

E.g: Client-Server, Peer-to-Peer.

Question 5

What is Client-Server?

Answer 5

Clients request data from server; servers provide data to clients.

Provides centralized control.

Question 6

What is Peer-to-Peer (P2P)?

Answer 6

Each computer is linked to one computer without going through a server.

Simple setup, no usernames/passwords, inexpensive.

Question 7

What is Centralized Control?

Answer 7

Network management handled by a single technician.

Question 8

What is Subnetting/Subnet Mask?

Answer 8

Dividing a physical network into smaller, manageable sub-networks.

Question 9

What is Automatic Configuration?

Answer 9

Device setup without manual intervention, simplifies connection.

Question 10

What is Manual Configuration?

Answer 10

Requires user input for device network setup.

Question 11

What is Topology?

Answer 11

Arrangement of devices and connections in a network.

Question 12

What is Star Topology?

Answer 12

Each device transfers data through a central device.

Question 13

What are the benefits of Star Topology?

Answer 13

If one cable fails, other devices are not affected; less data collision.

Question 14

What are the limitations of Star Topology?

Answer 14

Expensive installation; if the central device fails, the whole network goes down.

Question 15

What is Bus Topology?

Answer 15

All devices share a single communication line.

Question 16

What are the benefits of Bus Topology?

Answer 16

Less cable required; no specialized devices needed.

Question 17

What are the limitations of Bus Topology?

Answer 17

If bus fails, the whole network goes down; security issues due to all devices receiving packets.

Question 18

What is Mesh Topology?

Answer 18

Every device connected to every other device.

Question 19

What are the benefits of Mesh Topology?

Answer 19

Backup routes available if one cable stops working; fast communication.

Question 20

What are the limitations of Mesh Topology?

Answer 20

Very expensive; potentially difficult to install.

Question 21

What is Token Ring?

Answer 21

Every device connected to two other devices; messages move in one direction.

Question 22

What does Token Ring do?

Answer 22

Passes a message called a token around; devices add messages to the token.

Question 23

What are the benefits of Token Ring?

Answer 23

No specialized device required; no data collisions.

Question 24

What are the limitations of Token Ring?

Answer 24

One connection breaks, others cannot communicate; security issues.

Question 25

What is a Terminator?

Answer 25

Device preventing signal reflection in bus topology.

Question 26

What are Backup Routes?

Answer 26

Alternative paths for data if a connection fails.

Question 27

What is High Performance?

Answer 27

Network efficiency with minimal data collisions.
