The answer to this depends upon how you define "computer network". If you are referring to the internet, you can see the history at:
http://www.davesite.com/webstation/net-history.shtml
If you are referring to local area networks (LANs), I'd like to make a case for ARCnet, which was introduced commercially by Datapoint in 1977, though we used it internally before that. ARCnet used a token-ring architecture, supported data rates of 2.5 Mbps in its initial form, and connected up to 255 computers. One advantage of ARCnet was that it permitted various types of transmission media -- twisted-pair wire, coaxial cable, and fiber optic cable -- to be mixed on the same network. If I recall correctly, we had something like 6,000 ARC networks installed in customer sites when the first Ethernet was sold to a customer. ARC, by the way, stands for "Attached Resource Computer".
You can read more about ARCnet at:

but the diagram is wrong. It shows computers connecting directly to other computers, rather than all of them being connected to hubs as ARC requires.
ARCnet is still alive, though no longer used in its original capacity as a data processing and office automation tool. See:

What is the difference between an Ethernet Address and an mac address?
Ethernet address is really not a good term to use. I think you mean a MAC address. A MAC address is given to any device that accesses the internet. Such devices include WiFi cards, modems, and routers. These are only used by networks that devices connect to, and not by websites. They can be used for filtering and identifying devices on a network.Ip (Internet Protocol) addresses are assigned to networks (one per network) by an ISP (Internet Service Provider) such as Comcast. These are sent to everything you interact with online, so that your network, rather than your computer, is identified.Now there are two kinds of Ip addresses: internal and external. Internal are used by your network to identify each device that connects to it. External Ip's are assigned by your ISP to identify you to the world. I explained the difference more in-depth in another answer, which is right here:What_is_the_difference_between_an_Ip_address_and_a_http_address

How To Use A Network Computer?
A computer network is formed whenever two or more computers are joined together so that they can share information and communicate with one another. Sometimes this is done with wires such as Ethernet cables. Other times it is done with wireless routers in the same way that a wireless internet connection is set up. It is now very common for computers to be a part of a network, and fewer and fewer of them are operating on their own every year. This ability to work together is what makes computers so powerful, and it is nearly impossible to reach their full potential if you do not use them in conjunction with others. There are a few ways in which a network computer is different than a traditional computer, however, so you need to know what to expect so that you can use it effectively.The major different between a Network Computer and a traditional computer is that the latter has a disc drive while the former does not. A computer without a disc drive is set up only to work in a network format where everything can be shared. The disc drive is used to take information from one source and put it onto the computer. This is true for programs, music, movies, games, and anything else that comes on a disc. The network computer does not need this because it can get all of that information from the other computers or from the central server itself.A Network Computer is often not as large in terms of storage space as a standard personal computer. Again, this is because of the servers and the other computers to which it is connected. There is no point in giving a computer a lot of memory when it does not need it. The computer's memory is, in essence, stored on the bank of servers. You will need to connect to the server to see it, and it will be much larger there than it could ever be on a personal computer.In order to use the network computer effectively, you just need to remember that it is a portal to the servers and the other computers. It is not meant to be used on its own. The whole basis of its existence is centered around giving you a way to look at and manipulate the information that is located within the server, the network's heart.
