Focusing on what hardware(things really) is used to setup networks in different places.
Bridges
Used to divide a network
Ethernet networks
Hubs
They basically just act as repeaters for Ethernet signals
With hubs we find that one message gets sent to everybody but only picked up and used by the intended receiver
Switches
Associates ports w/ mac address of whatever is plugged into that port. Reads the source/destination in the Ethernet frame header to create that association.
This is much better because now the whole network doesn't get spammed like with hubs. Also the collision domain lies between the switch and the host connected now.
LAN Segment w/ Routers
If we have two subnets next to each other: routers allow comms between the two.
VLAN
VLANs themselves are similar to subnets but really act as subnets for routers.
