It's important to regularly test the backups to ensure they can be restored in case of data loss."

22. What is the difference between a router and a modem?

Why you might get asked this: This question tests your understanding of network devices and their functions.

How to answer:

• Clearly define both router and modem.

• Explain their different roles in connecting to the internet and distributing network traffic.

Example answer:

"A modem is a device that connects your home network to your Internet Service Provider (ISP). It converts the analog signal from your ISP into a digital signal that your computer can understand. A router, on the other hand, distributes the internet connection to multiple devices within your network, creating a local network and managing traffic between devices."
