Identify the correct diagram of a star network topology.

• A central node connected to multiple peripheral nodes, with no direct connections between the peripherals.

• All nodes connected in a closed loop, each node connected to two others.

• Each node connected to every other node directly.

• Nodes connected in a single line, one after another.

Two advantages of a star network topology are:

• Easy to add new devices and easy to detect faults

• All devices are directly connected to each other and uses less cable

• Difficult to manage and high cost

• Slower data transfer and complex setup

One disadvantage of a star network topology is:

• If the central hub fails, the whole network is affected.

• It is the most expensive topology to implement.

• It is the slowest network topology.

• It is difficult to add new devices.

The role of both the TCP and IP protocols in network communication is to:

• TCP ensures reliable data transmission, while IP handles addressing and routing.

• TCP handles addressing and routing, while IP ensures reliable data transmission.

• Both TCP and IP are responsible for encrypting data.

• TCP and IP are only used for wireless communication.

Which of the following are items of information found in a TCP/IP packet, apart from the Destination Address?

• Source Address, Sequence Number, Checksum

• MAC Address, File Size, Username

• Printer Name, Font Type, Page Number

• Monitor Resolution, Color Depth, Refresh Rate
