What is the role of a server in a computer network?

To provide services to other computers

To receive and print documents only

In data communication, what is the medium?

The software installed on the sender

What is guided transmission media?

Media that uses physical path like cables

Media that uses GPS to track devices

What is the purpose of twisting the wires in a twisted pair cable?

To reduce electromagnetic interference

What is the main difference between UTP and STP cables?

STP has a metallic shield around the wires

UTP is made of plastic; STP is made of glass

UTP supports higher speed than STP

UTP has better immunity from EMI than STP

What is a “terminator” used for in coaxial cable networks?

To stop signal reflection at the end of the cable

To protect the cable from physical damage

What happens to light when it travels from a denser medium like glass to a less dense medium?

It accelerates and bends away from the normal

It accelerates and bends toward the normal

It slows down and bends toward the normal

It slows down and bends away from the normal

What does the process of refraction involve?

A light wave changing direction due to a change in speed

What is the main purpose of a modem?

Converting digital signals to analogue and vice versa

What is the function of a router in a network?

Connects multiple networks and manages best data routes

Acts as a wireless signal booster

Stores and secures data packets

What does a Hub do in a network?

Transmits signals to devices and handles one-way traffic

Converts digital data to analog

Acts as a wireless access point

What does a bus topology use to connect all devices?

Backbone cable with drop lines and taps

Circular loop connecting each device

Mesh connections between all nodes

What is one of the major disadvantages of the Bus Topology?

The network is disrupted if any cable breaks.

It is easy to add new workstations.

It uses a central hub to manage communication.

It is more expensive to maintain than a ring topology.

In Bus Topology, how does a workstation know if a message is addressed to it?

The message is broadcasted to all devices, and each workstation checks if the message is addressed to it.

The central hub checks if the workstation is the intended recipient.

Each device in the network receives all messages regardless of the destination.

The workstation receives the message only if it is part of the trunk.

Which of the following is true about a Trunk in Bus Topology?

It is a dedicated channel between two points.

It is a network switch that routes data between devices.

It is used to increase the distance covered in the network.

It is a cable that connects multiple workstations in a star topology.

What makes Bus Topology difficult to maintain?

The entire network goes down if one cable is broken.

The need to install multiple hubs and switches.

The network requires a dedicated point-to-point connection between devices.

It requires frequent upgrades to support new workstations.

Which of the following is an advantage of Star Topology over Bus Topology?

If one device goes down, the rest of the network is unaffected.

It is easier to add new devices without disrupting the network.

It uses less cabling than Bus Topology.

What is a major disadvantage of Star Topology?

The central device (hub) failure causes the entire network to go down.

It requires minimal maintenance.

It is difficult to add new workstations to the network.

In Ring Topology, how does data circulate?

The data circulates in a single direction from device to device.

The signal is passed through a central hub before reaching its destination.

Data is broadcast to all devices simultaneously.

Each device randomly chooses a path to forward the data.

Which of the following is a limitation of Ring Topology?

If one device is removed, the entire network is disrupted.

It is very easy to add new devices to the network.

It is not suitable for networks with many devices.

It uses less cabling than Star Topology.

What is the main characteristic of Mesh Topology?

Each device is connected to every other device in the network.

All devices are connected in a single line.

It uses a central hub to manage communication.

Devices are arranged in a tree-like structure.

What is a disadvantage of Mesh Topology?

It is expensive to install and maintain due to the large number of cables.

It is highly scalable and flexible.

Which of the following best describes data flow in Simplex mode?

Data flows in one direction only, like a one-way street.

Data flows in both directions simultaneously.

Data can flow in both directions, but not at the same time.

Data flows in both directions but alternates between sending and receiving.

In Half Duplex mode, what is a limitation of the devices?

They can either send or receive data, but not at the same time.

They can send and receive data simultaneously.

Data flows in one direction only, like in Simplex mode.

Data is transmitted continuously in both directions.

Which of the following is a characteristic of Half Duplex communication?

Data is transmitted one way at a time.

Data can flow simultaneously in both directions.

Devices can only send data, not receive.

The transmission speed is very fast.
