Networks & Topologies

What is a computer network?

• A device that stores data permanently.
• A standalone computer that operates independently.
• A type of software used for programming.
• A system that connects computers to share resources and information.

Which of the following is an advantage of wired networks?

• Higher security compared to wireless networks.
• Easier to set up than wireless networks.
• More portable than wireless networks.
• Less expensive to install than wireless networks.

What is one disadvantage of wireless networks?

• They are not suitable for mobile devices.
• They require more physical cables than wired networks.
• They are always faster than wired networks.
• They can be less secure than wired networks.

What is one advantage of wireless networks over wired networks?

• Greater mobility for users.
• They are always more reliable.
• They require no power supply.
• They are less susceptible to interference.

In a star topology, how are devices connected?

• Randomly without a specific structure.
• In a circular pattern.
• In a straight line to each other.
• Through a central hub or switch.

What is a key benefit of computer networks?

• They enable resource sharing among multiple users.
• They eliminate the need for any hardware.
• They make all devices completely independent.
• They are always faster than standalone systems.

Which of the following best describes a bus topology?

• All devices share a single communication line.
• Each device connects to a central node.
• Devices are arranged in a circular layout.
• Devices are connected in a star formation.

What is a disadvantage of using a star topology?

• Devices can communicate directly with each other without a hub.
• It is the most cost-effective topology.
• It requires less cabling than other topologies.
• If the central hub fails, the entire network goes down.

Which of the following is a common use for computer networks?

• Creating a backup on a single computer.
• Running applications without any internet connection.
• Storing software on a single device only.
• Connecting multiple computers to share files and printers.

What does a wireless network use to connect devices?

• Radio waves or infrared signals.
• Physical cables like Ethernet.
• Optical fibres exclusively.
• Satellite signals only.
