	The whole idea of a Local Area Network is relatively recent, as it wasn't until May 22nd, 1973 at the Xerox Palo Alto Research Center (PARC) that the world's very first LAN was set up. Bob Metcalf and David Boggs were the computer scientists involved in this research, and by using an ethernet cable they were able to transfer there first packet of data between two computers on this very day. Both Metcalf and Boggs spent the next several years working on the idea of a LAN, and by 1976 they were able to connect and transfer information between over 100 computers. This is where our modern idea of a local area network was started. This relatively simple idea was the foundation of how many businesses are set up to this day, as they can easily transmit data between any computer in a building.

	Local Area Networks are most commonly referred to a group of computers connected together that are able to share information, and transfer dats amongst the networked computers. Local Area Networks are used to connect as few as two computers, which is common in households, or as many as thousands of computers in the case of businesses.

	Now as mentioned above, Local Area Networks are used very frequently in all sorts of places. In fact nearly every business and school probably has some sort of LAN set up. For example McMaster University has quite a large LAN set up throughout the campus. There are a couple of very helpful uses that this LAN provides for students. For one, because of the LAN, students are able to print from any computer in the school, without each individual computer needing its own printer. This not only saves money but also greatly reduces clutter throughout the campus.		Now as mentioned above, Local Area Networks are used very frequently in all sorts of places.

	There is one more very important idea to get a very clear picture of how a local area network works. If all the computers on a network were connected through one main ethernet cable, there would obviously be a lot of traffic and congestion on this cable, and if the network contained hundreds of computers all transmitting and receiving data there would most likely be a lot of slow down throughout the network. This is why a Bridge was created. Like a repeater, a bridge can connect several ethernet cables together to create one large network. However, unlike a repeater, the bridge is actually able to direct traffic. For example if a repeater is connecting two sets of ethernet cables together, it does not "repeat" the information to the second ethernet cable if the destination address lies within the first ethernet cable. This simple idea can decrease the amount of traffic on a network and greatly increase any slow down in the network.

	Now more recently, we have almost entirely eliminated wires within our local area network. However the basic principle of how a local area network works still remains the same. Instead of using copper wires, the information is sent through radio signals. Every computer that is able to receive information has a very tiny antenna on it that allows it to receive and decode the radio frequency to use the information. The basic idea of the repeaters and bridges still remain the same. However they also have small antennas on them, and are able to retransmit the data as needed.

-	Furthermore, when a student wants to save his or her work, they have the option of saving it on the network drive. By doing this, that student would not need to come back to the very same computer that they had been working on previously. Instead they can go to any other computer and access the network drive to retrieve there work from any computer around campus. Without having a LAN set up, it would be very difficult to have to save your work on a local drive, and than hope that the very same computer was not being used on a different day, when one wanted to retrieve there saved ~~file~~.	+	Furthermore, when a student wants to save his or her work, they have the option of saving it on the network drive.

-	On the other hand, Local ~~area networks~~ also have a very useful recreational use. Sure they can greatly increase the effectiveness of a work place or school computer, but they can also be used for gaming LAN's. Game Design students, and gamers in general are well aware of how effective a LAN can be while playing a computer game. A LAN allows dozens of players to join the same game and play against each other in nearly every game on the market today. This kind of scenario has opened the doors to local gaming LAN parties, where in many cases prizes can be awarded to the best players.	+	On the other hand, Local Area Networks also have a very useful recreational use.
