Hubs don’t segment a network. They just connect network segments together. So, ‘materi kuliah’ don’t allow of you use a hub in a big network.
How about router? Router can connect networks together and route packets of data from one network to another. Routers, by default, break up a broadcast domain and set all of devices on a networking segmen.
Routers can also provide packet filtering by using access lists, and when routers connect two or more networks together and use logical addressing (IP or IPv6), this called an internetwork. Last, routers use a routing table (map of internetwork) to make path selections and to forward packets to remote networks.
switches aren’t use to create internetworks and switches do not break up broadcast domains by default, switches have functionality to a network LAN. The main purpose of a switch is to make a LAN works better to optimize its performance. Providing more bandwidth for the LAN users, switch don’t forward packets to another networks as routers do. Instead, they only “switch” frames from one port to another within the switched network.
Bridges and switches???
Basicly bridge and switches do the same thing, break up the collision domain on a LAN. but its differences:
- Bridge in a network to reduce collisions within broadcast domains and to increase the number of collision domains in network.
- Bridge was used to connect the hubs to a router. The bridge breaks up collision domains, but all the hosts connected to both hubs are still crammed into the same broadcast domain.
- The bridge only created two collision domains, so each device connected to a hub is in collision domain as every other device connected to that same hub. This is actually pretty lame, but it’s still better than having one collision domain for all hosts.
