Group 8 : TOPIC 2.1
-
- Identify device connectivity options.
Repeater
Repeaters operate in the Physical layer of the OSI
model-no means to interpret the data they retransmit.
-
-
Router
-
-
Routers can integrate LANs and WANs running at different transmission speeds and using a variety of protocols.
Hub
Hub accepts signals froma transmitting node and repeats those signals to all other connected nodes in broadcast fashion.
Because of their limited features and thefact that they merely repeat signals within a single collision domain, hubs were replaced by routers and switches.
-
Modem
-
Convert either digital signal to analog signal (modulation) and analog signal to digital (demodulation)
Bridges
Bridges are devices that connect two network segments by analysing incoming frames and makingdecisions about where to direct them based on each frame’s MAC address
-
-
Switches
-
Because they have multiple ports, switches can make better use of limited bandwidth and prove more cost efficient than bridges.
-
Switches are connectivity devices that subdivide a network into smaller logical pieces, or segments.
