In the backbone wiring
c. in the NICs
In the NIC. MAUs have tranceivers but aren't used on 100BASE-TX networks.
Yaesu transceivers can be bought online. You can find these transceivers on sites like Amazon, Yaesu dot com or even pilot dot com. You can find them on many of the sites that sell items like these.

An ethernet network hub can be easily found at a local electronic store like Bestbuy or Future Shop. It can also be found on eBay and Amazon at great prices.
Any ethernet cable will work. I suggest monoprice.com for cheap cables, but retailers like Bestbuy, or newegg.com might have one.

Quickest way to find out is to do a web search.
You can find a process control network located at any large or small company that uses a base computer system. It is basically an ethernet system. It allows the company to have a connected system that communicates with each other.
LAN stands for Local Area Network. It describes the kind of network you have. It is a data communications network limited to around a 1-km radius.Because the network is known to cover only a small area, optimisations can be made in the network signal protocols that permit data rates up to 100Mb/s.Ethernet, on the other hand, refers to the cabling system of the network. It is a way to interconnect computers to form a network. From "Ethernet: The Definitive Guide" by Charles Spurgeon,Quote:Metcalfe's first experimental network was called the Alto Aloha Network. In 1973 Metcalfe changed the name to "Ethernet," to make it clear that the system could support any computer-not just Altos-and to point out that his new network mechanisms had evolved well beyond the Aloha system. He chose to base the name on the word "ether" as a way of describing an essential feature of the system: the physical medium (i.e., a cable) carries bits to all stations, much the same way that the old "luminiferous ether" was once thought to propagate electromagnetic waves through space. Thus, Ethernet was born."--from "Invention of Ethernet", "Ethernet: The Definitive Guide" by Charles SpurgeonEthernet can also mean the physical hardware (the cables). There are many of these: 10Base-T, 10Base-2, 10Base-5, 10Base-F, and the like. There are also faster ones, namely 100BaseT (Fast Ethernet) and 1000BaseT (Gigabit Ethernet).You can find more info at Charles's Spurgeon's Ethernet (IEEE 802.3) website.
You don't - you'll need an Ethernet card for your computer. A regular voice/fax modem is different than a high-speed/network connection, so you need a different 'card' (with a socket that will match your cable). If you can't find a socket that your Ethernet cable fits, then you don't have an Ethernet card installed!
The Media Access Control (MAC) address is a number that identifies a computer connected to a network. To find the MAC address on an Apple Mac select About This Mac in the Apple menu (top left), then click on More Info and then on Network in the left hand pane. The MAC address will be listed under Ethernet in the lower right hand pane.
