List two advantages of using a wireless network over a wired network.

• Less interference from other devices

• Mobility and easier installation

• More secure data transmission

• Faster speed and lower latency

Explain the concept of packet switching in data networks.

• Packet switching involves sending data in a continuous stream without any division.

• Packet switching ensures that all packets follow the same route to the destination.

• Packet switching requires a dedicated point-to-point connection for data transmission.

• Packet switching involves breaking down data into packets, each with a header containing destination information. These packets are then sent independently across the network and reassembled at the destination.

What is the role of DNS in networking?
