Network Characteristics

Question 1

What Is A Node?

Answer 1

Devices or Points With A IP Address

Question 2

What Is Peer To Peer Networking?

Answer 2

there is no central server. Instead, each workstation is loaded with the appropriate applications needed for that machine and local resources such as an attached printer folder or external hard drive can be shared.
The peer-peer network form is most commonly found in the home or a small office.

Question 3

3 Advantages?

Answer 3

1. No need for a Network operating system.
2. Doesn’t need an expensive server.
3. No need for specialist staff.

Question 4

3 Disadvantages?

Answer 4

1. Files and folders can’t be centrally backed up.
2. Files and resources aren’t centrally organised into a specific shared area.
3. Ensuring viruses aren’t introduced to the network is the responsibility of the individual.

Question 5

What Is Client Server?

Answer 5

With a client server network the files will not be stored on the hard drive of each workstation. Instead they will be stored on a specialised computer called a server. A server is designed to efficiently provide data to a remote client.

Question 6

3 Advantages Of A Client Server?

Answer 6

1. Files are stored in a central location
2. Backup And Network Security Is Managed Centrally
3. Users can access centrally located files

Question 7

Definition Of Bus Network

Answer 7

In a bus network all the workstations, servers and printers are joined to one cable

Question 8

3 Advantages?

Answer 8

1. Easy to install
2. Easy to add extra workstations
3. Best choice for temporary networks

Question 9

3 disadvantages?

Answer 9

1. Problem with central cable means the whole network goes down
2. Lots of workstations = slow data transfer
3. Low Security All workstations have access to all data

Question 10

Star Topology Definition

Answer 10

The workstations radiate out from one point in a star shape

Question 11

3 Star topology advantages?

Answer 11

1. Very Few Data Collisions - every workstation has dedicated cable to server
2. Very Reliable one workstation is down the rest will still be up
3. Good Security

Question 12

3 Disadvantages of Star Topology?

Answer 12

1. Most Expensive Server Layout
2. Installing Network needs experts
3. Server crashes no one will be able to access files

Question 13

What is a mesh topology?

Answer 13

full mesh topology, every computer in the network has a connection to each of the other computers in that network

Question 14

3 Advantages Of Mesh Topology?

Answer 14

1. It can withstand high data traffic at the same time
2. Expansion can be done without distribution
3. If one component fail the rest stay up

Question 15

3 Disadvantages Of Mesh Topology?

Answer 15

1. Connections are not fully utilised
2. Overall cost of the network is too high!
3. Setup and maintenance costs a lot and is a frustration

Question 16

Ring Topology Definition?

Answer 16

All the computers are connected to one another in a circle

Question 17

2 Advantages Of Ring Topology?

Answer 17

1. Extra computers can be added, although shutting down the network is necessary
2. Transmission of data is simple because it only travels one way

Question 18

3 Disadvantages Of Ring Topology?

Answer 18

1. If a cable breaks the network does not work
2. Data must pass through each workstation before arriving at it’s destination
3. Difficult to identify cause of problems if any occur

Question 19

What is an address?

Answer 19

The unique number ID assigned to one host or interface in a network

Question 20

What is a subnet?

Answer 20

A portion of a network that shares a particular subnet address.

Question 21

What is a subnet mask?

Answer 21

A 32 bit combination used to describe which portion of an address refers to the subnet and which part refers to the host.

Question 22

How many Bits are there in one octet?

HINT*(OCT =?)

Answer 22

8 bits

Question 23

What is IP addressing?

Answer 23

It is a unique address that identifies a computer on a network such as the Internet.

Question 24

Why is IP addressing used?

Answer 24

it allows computers to send and receive information to and from specific computers in a given network.

Question 25

What is Default Gateway?

Answer 25

it is a access point or IP router that a networked computer uses to send information to a computer in another network

Question 26

What is Default Gateway Used For?

Answer 26

The device can provide services such as file sharing, web hosting, and Internet connection sharing to the local network

Question 27

What is subnet mask?

Answer 27

A subnet mask is a number that defines a range of IP addresses that can be used in a network

Question 28

What is Subnet Mask Used For?

Answer 28

Used to identify which subnet an IP address belongs to
