Which network topology is the most resilient when nodes are offline?
Mesh
Star
Bus
Ring
What are the benefits of using a star network topology?
Uses less cable per node
If a node goes down it's unlikely to affect the rest of the network
Higher speeds and less congestion
Nodes can repeat and pass on data between them to make the network highly resilient
What are the benefits of using a mesh network topology?
Uses less cable per node
If a node goes down it's unlikely to affect the rest of the network
Higher speeds and less congestion
Nodes can repeat and pass on data between them to make the network highly resilient
Question 2: Which is a feature of a Mesh Network? (5-6)
Data can be transmitted from different devices simultaneously.
Devices are dependent on a central sever.
The network uses terminators
The Server is usually based in the middle of the network
Question 8: Which term describes the physical layout of a Network? (1-4)
Topology
Topping
Topiary
Toppology
Which layer does TCP operate on
Application
Transport
Network
Link
Which is the right order for network layers
Application Link Transport Network
Application Transport Link Network
Application Transport Network Link
Transport Link Network Application
What is meant by a data packet?
A unit of data that travels along a network
The number of error found in data when it has been transmitted
The data a computer needs to connect to a network
A connection point in a network that allows data to be shared
Which layer does IP operate on
Application
Transport
Network
Link
Which protocol is used for sending emails?
POP
IMAP
SMTP
FTP
Which of these never changes on a device
MAC address
IP address
What is an advantage of IMAP over POP
It is quicker
It can cope with more email messages
It will synchronise all devices with the users mailbox
It has more space to store old messages
Which layer splits data into packets?
Transport Layer
Application Layer
Network Layer
Link Layer
Which of the following Protocols is used for sending e-mails between servers?
