A hub sends packets to all connected nodes and it has no intelligence.
Advantages:
Its very cheap
No set up needed
Disadvantages:
Many collisions
Very inefficient
Generates lots of redundant traffic

A switch= inspects packets to see where they are going also uses LAN's
Advantages:
Very few collisions
Increased performance/efficiency
Disadvantage: can be hard to set up

A router=Internet connectivity device its very intelligent! it connects networks together on the internet. It also connects networks to the internet. Routers broadcast connectivity information to each other, they can also automatically find alternative paths through a network. It selects the best path for each packet based on knowledge of a network.
Pieces of network hardware:
A bridge network is a device that filters data traffic at a network boundary. Bridges reduce the amount of traffic on a local area network (LAN) by dividing it into two segments. The advantage is it's cheap, easy, doesn't require routing to work. These virtual bridges can calculate and choose the shortest path for data, prevent network loops, and other useful stuff. The disadvantages are it doesn't support routing (so both networks form one large broadcast domain and see each others traffic), and most bridges don't support any kind of traffic filtering. Bridges aren't much used any more on physical LANS, but are important on virtual LANS and in wireless. Those bridges are much "smarter" than the old physical ones, and the ability to manage an entire virtual LAN as a single network is important. |

In computer networks, a proxy server is a server (a computer system or an application) that acts as an intermediary for requests from clients seeking resources from other servers.
Advantages:
Hidden IP Address
Reduction of Load
Control Over Services
Security
Speedy Internet Access
Disadvantages:
Additional Investment

A file server is a device which controls access to separately stored files, as part of a multi-user system.
Backup Server is an Open Server-based utility that handles all dumps and loads for SQL Server releases 10.0 and later. Backup Server provides flexible syntax for the dump and load commands and eliminates the need for the console program.
A print server, or printer server, is a device that connects printers to client computers over a network. It accepts print jobs from the computers and sends the jobs to the appropriate printers, queuing the jobs locally to accommodate the fact that work may arrive more quickly than the printer can actually handle it.
A network interface is the point of interconnection between a computer and a private or public network. A network interface is generally a network interface card (NIC), but does not have to have a physical form.
