Answer 1

A) Modem

A modulator-demodulator, or simply modem, is a computer hardware device that converts data from a digital format into a format suitable for an analog such as telephone or radio.

Answer 2

Networking Devices for Local Area Networks

When it comes to connecting multiple network hosts and exchanging data within a local area network (LAN), there are several networking devices that can be used. These devices help facilitate communication and data transfer between devices on the same network. The options you provided are:

- Router: A router is a networking device that connects multiple networks together and directs network traffic between them. It acts as a central hub for data transmission between devices on different networks. Routers use IP addresses to determine the best path for data packets to reach their destination.

- Switch: A switch is a networking device that connects multiple devices within a LAN. It operates at the data link layer of the OSI model and uses MAC addresses to forward data packets to the appropriate destination device. Switches provide dedicated bandwidth to each connected device, allowing for efficient data transfer within the LAN.

- Hub: A hub is a basic networking device that connects multiple devices within a LAN. Unlike switches, hubs operate at the physical layer of the OSI model and simply broadcast incoming data packets to all connected devices. This means that all devices connected to a hub share the available bandwidth, which can lead to network congestion and slower data transfer speeds.

- Modem: A modem is a device that connects a computer or network to an internet service provider (ISP) and enables internet access. It converts digital data from the computer or network into analog signals that can be transmitted over telephone lines or cable lines, depending on the type of modem. Modems are typically used to connect to wide area networks (WANs) such as the internet.

- Repeater: A repeater is a networking device used to extend the range of a network by amplifying and retransmitting signals. It receives incoming signals, strengthens them, and then sends them out again to reach devices that are located further away. Repeaters are commonly used in wireless networks to improve signal strength and coverage.

Conclusion

In summary, the networking devices used to connect multiple network hosts and exchange data within a local area network (LAN) include routers, switches, hubs, modems, and repeaters. Each device serves a specific purpose in facilitating network communication and data transfer. Routers connect multiple networks together, switches connect devices within a LAN, hubs broadcast data to all connected devices, modems provide internet access, and repeaters extend the range of a network.
