WHAT ARE THE OTHER NETWORK DEVICES?

 NETWORK BRIDGE - A network bridge is a hardware device that can expand a local area network by connecting multiple networks or allowing more devices to connect to a single network than would normally be possible.

NETWORK CARD - A Network interface card (also known as a NIC, network card, or network interface controller) is an electronic device that connects a computer to a computer network, usually a LAN. It is considered a piece of computer hardware.

MODEM - A modem is a network device that connects your local area network (LAN) to the wide area network (WAN), also known as the internet. Most modems are connected via a phone line, coaxial cable, or optical Fiber.

TRANCEIVER - A transceiver is an electronic device which is a combination of a radio transmitter and a receiver, hence the name. It can both transmit and receive radio waves using an antenna, for communication purposes. These two related functions are often combined in a single device to reduce manufacturing costs. 

FIREWALL - a firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules.MA firewall typically establishes a barrier between a trusted network and an untrusted network, such as the internet.
