What does a modem do in a computer network?

• Converts digital signals to analog and vice versa

• Distributes data within a network

• Connects LANs using bridges

• Provides wireless connectivity

What is the typical transmission speed of dial-up modems?

• 100 kilobits per second

• 60 kilobits per second

• 1 megabit per second

• 10 megabits per second

What does ADSL stand for?

• Asymmetric Digital Subscriber Line

• Advanced Digital Signal Line

• Analog Data Subscriber Line

• Automated Digital Service Line

Why is ADSL considered 'asymmetric'?

• It uses both fiber-optic and copper cables

• It has faster downloading speeds than uploading speeds

• It connects multiple devices simultaneously

• It provides equal upload and download speeds

What is the main advantage of ADSL modems over dial-up modems?

• They allow telephone conversations and internet traffic simultaneously.

• They are cheaper than dial-up modems.

• They require less power to operate.

• They provide faster download speeds only at night.

What is the primary function of a hub in a network?

• To connect different LANs using different protocols.

• To take a data packet and broadcast it to every computer in the network.

• To encrypt data packets for secure transmission.

• To store data packets temporarily.

How does a switch differ from a hub in terms of data distribution?

• A switch encrypts data packets before sending them.

• A switch sends data packets to the appropriate computer(s) only.

• A switch broadcasts data packets to all computers in the network.

• A switch stores data packets for future use.

What is a MAC address used for in a network?

• To encrypt data packets.

• To uniquely identify each device or computer on a network.

• To store data packets temporarily.

• To connect different LANs.

What is the purpose of a bridge in a network?

• To connect different LANs that use the same protocol.

• To encrypt data packets for secure transmission.

• To broadcast data packets to all computers in the network.

• To temporarily store data packets.

What is the primary function of a router in a network?

• To connect computers directly to the internet

• To route data packets between different networks

• To store data packets temporarily

• To provide power to network devices
