File servers
A very fast computer with a large amount of RAM and storage space along with a fast network interface card
The network operating system software resides on this computer
Network interface cards
The network interface card (NIC) provides the physical connection between the network and the computer workstation.
Most NICs are internal with the card fitting into an expansion slot in the computer.
Three common network interface connections are Ethernet cards, Local Talk connectors and Token Ring cards
Switches
hubs provide an easy way to scale up and shorten the distance that the packets must travel to get from one node to another
they do not break up the actual network into discrete segments. That is where switches come in.
Bridges
A bridge is a device that allows you to segment a large network into two smaller, more efficient networks
Thin Coaxial Cable
Alternative to Thick Ethernet Cable
Type RG-58 / 10Base2 / “Cheapnet”
Usually black
Thickness of a pencil
More flexible than thick Ethernet
Reduced the cost of the cabling
