This question has many different intakes and types of answers. Ill answer the most common references. Hardware that allows computers to talk to the simplist level is a ethernet card. With an ethernet card on both computers using a crossover cable you can connect them with each other and allow them to talk. Another more popular piece of hardware that connects computers and allow them to talk is the infamous router. A router is a workstation that connects all computers together and they can share files, media, and an internet connection. If you talking on the wireless level bluetooth and adhock connections allow computers to talk.

Hope this helps!

What is a small inexpensive device that joins multiple computers together?

There are loads! USB cables with double A type connectors can, WiFi can be used either directly or indirectly via a router/hub. Serial cables can be used to do a direct transfer although it has a slow baud rate. You can use 2 network cables vis a hub, switch or router - you can also use a single network cable if its a crossover cable. You can use bluetooth, Infa-red or any other number of wireless mesiums. I've used an old parallel printer cable before! Either way - you need 3 common elements to do a transfer: - A physical connection - the hardware used to make the transfer - A logical connection - a common language (or protocol) for the physical hardware to 'talk' with and - An application connection. usually an operating system, FTP program, web browser, firmware - something to build and deconstruct the data sent over the connection

What is a an STP networking cable and what is its use?

STP stands for shielded twisted pair. when you look inside a networking cable there are six different wires these wires are "paired" and these pairs are twisted. The purpose of this is to prevent something known as cross talk. Cross talk is where the signalalong the wire experiences an electromagnetic interference induced by Eddie currents By twisting the two wires this phenomena, is cancelled out and the data can then be transmitted without interference There are a few types of networking cable commonly in use UTP (un-shielded) STP and coaxial UTP is generally a lot cheaper than STP so is used more commonly however STP cables also have a "shielding" which surrounds each twisted pair as well as a main shield "shielding" all three pairs. This provides more protection from "external" sources of interference such as power sources or strong signals. These cables are used to link computers to other computers, or computers to other parts of the network such as "switches" or "routers". The cables can be wired in different ways depending on the use. Connecting computers to each other allows you to create an "intranet" where users can easily share and exchange data, share internet links, or share software/hardware also connected to that network - Jason MEng
