Hub

- commonly used to connect segments of a LAN. A hub contains multiple ports.
When a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

Multistation Access Unit
(MAU)
- a hub or concentrator that

connects a group of computers
('nodes' in network terminology) to a token ring local area network.

Bridges

- used to join two network segments together, it allows computers on either segment to access resources on the other - can also be used to divide large networks into smaller segments Networking Devices ...
Routers
-

networking devices used to extend or segment networks by forwarding packets from one logical network to another
- most often used in large internetworks that use the TCP/IP protocol suite and for connecting
TCP/IP hosts and local area networks (LANs) to the Internet using dedicated leased lines

Gateways

- a device used to connect networks using different protocols. - receive data from a network using one type of protocol stack, removes that protocol stack and repackages it with the protocol stack that the other network can use.

Network Interface Card
(NIC)

- a hardware card installed in a computer so it can communicate on a network.

Integrated Services Digital
Network (ISDN) Adapters
- can be used to send voice, data, audio, or video over standard telephone cabling.
- must be connected directly to a digital telephone network.
- not actually modems, since they neither modulate nor demodulate the digital ISDN signal. Networking Devices ...
Wireless Access Points
(WAPs)

- A wireless network adapter card with a transceiver sometimes called an access point, broadcasts and receives signals to and from the surrounding computers and passes back and forth between the
