LP 1

Question 1

is the way a network is arranged, including the physical or logical description of how links and nodes are set up to relate to each other.

Answer 1

Network topology

Question 2

two categories in the network topology

Answer 2

1. Physical network topology
2. Logical network topology

Question 3

Types of Network Topology

Answer 3

• Mesh Topology
• Bus Topology
• Ring Topology
• Tree Topology
• Hybrid Topology

Question 4

consists software and hardware that is used to send and receive data from one device to another.

Answer 4

computer network

Question 5

OSI Model stands for?

Answer 5

Open System interconnection model

Question 6

defines how data is transferred from one computer to another computer.

Answer 6

OSI Model (Open System interconnection model)

Question 7

A ________ topology is an intricate and elaborate structure of point-to-point connections where the nodes are interconnected.

Answer 7

Mesh Topology

Question 8

A _________ topology orients all the devices on a network along a single cable running in a single direction from one end of the network to the other—which is why it’s sometimes called a “line topology” or “backbone topology.”

Answer 8

Bus topology

Question 9

______ topology is where nodes are arranged in a circle. can travel through the ring network in either one direction or both directions, with each device having exactly two neighbors.

Answer 9

Ring Topology

Question 10

a _________ topology has a parent-child hierarchy to how the nodes are connected. Those connected to the central hub are connected linearly to other nodes, so two connected nodes only share one mutual connection. (topology is a combination of a star network topology and a bus topology)

Answer 10

Tree Topology

Question 11

__________ topologies combine two or more different topology structures—the tree topology is a good example, integrating the bus and star layouts.

Answer 11

Hybrid Topology

Question 12

A ____________ is a piece of hardware that acts as the interface for a computer to a network. This way, computers can communicate across a network.

Answer 12

network adapter

Question 13

It is a system where each computer listens to the cable before sending anything through the network.

Answer 13

Ethernet

Question 14

receives the data from network layer

Answer 14

Data link layer

Question 15

How to Troubleshoot a Network

(7 STEPS to troubleshoot)

Answer 15

1. Check hardware
2. Use ipconfig
3. Use ping and tracert
4. Perform a DNS check
5. Contact the ISP check
6. Check on virus and malware protection
7. Review database logo

Question 16

different codes used to indicate the differs types of shielding:

Answer 16

• U/UTP - Unshielded cable, unshielded twisted pairs
• F/UTP - Foil shielded cable, unshielded twisted pairs
• U/FTP - Unshielded cable, foil shielded twisted pairs
• S/FTP - braided shielded cable, foil shielded twisted pairs

Where: TP = twisted pair, U = unshielded, F = foil shielded, S = braided shielding.

Question 17

2 types of ethernet cables

Answer 17

STRANDED CABLE
SOLID CABLE

Question 18

This type of wire is more flexible and it is more applicable for Ethernet cables where the cable may be moved - often it is idea for patch leads at desks or general connections to PCs, etc where some movement may be needed and expected.

Answer 18

Stranded cable

Question 19

is not as flexible as the stranded type, but it is also more durable. This makes it best for use in permanent installations like cable installations under floors, embedded in walls and the like.

Answer 19

Solid cable

Question 20

It is a method of transferring data packets from source to destination.

Answer 20

Routing

Question 21

converts these binary sequences into signals and transfer it through a transmission media such as cables etc.

Answer 21

Physical Layer

Question 22

receives the data from network layer.

Answer 22

Data link layer

Question 23

is to receive the data segments from transport layer and transfer them from one computer to another computer on different network.

Answer 23

Network layer

Question 24

Builds on the network layer in order to provide data transport from a process on a source system machine to a process on a destination system

Answer 24

Transport layer

Question 25

is to setup and maintain the connection between different systems.

Answer 25

Session Layer

Question 26

receives the data from top most layer which is application layer.

Answer 26

Presentation Layer

Question 27

is used by computer applications such as google chrome, outlook, FireFox, Skype etc.

Answer 27

Application layer
