Explain the concept of dynamic routing.

• Dynamic routing is a static process that does not change over time.

• Dynamic routing does not consider network congestion or traffic load.

• Dynamic routing only involves a single router making decisions on packet forwarding.

• Dynamic routing involves routers exchanging routing information with each other to determine the best path for data packets to reach their destination.

How can encryption be used to secure a network?

• By leaving data unencrypted for faster access

• By using the same encryption key for all users

• By sharing encryption keys publicly

• By encoding data in a way that only authorized parties can access it.

What are the advantages of wireless networking?

• Limited security

• Inconsistent connection

• Advantages of wireless networking include mobility, easy installation, scalability, cost-effectiveness, and flexibility.

• High maintenance costs

Describe the process of setting up a wireless network.

• Configuring a wireless network requires connecting an Ethernet cable to each device

• The process involves choosing a router, connecting it to a modem, accessing router settings, configuring network name and password, and connecting devices.

• Setting up a wireless network involves connecting a printer directly to the router

• The process of setting up a wireless network includes installing a satellite dish on the roof
