It’s becoming increasingly clear to me as the years pass by that I actually know more than I did let’s say twenty or thirty years ago. Now most of you may be saying right now , yes you should know more than you did twenty or thirty years ago and I would agree with you 100%. But how many of us when we say that about ourselves actually believe it.

I came to this realization when I started teaching Bartending at a local college that I actually know more than most in my chosen field. The students I was teaching were approximately the same age as I was when I was a student learning the Bartending trade. The difference was now I was responding to questions that I thought everybody should know the answer to. Then I realized I was the teacher and when I was in their shoes I probably did not know the answer 30 years ago either. That is when I realized that I truly did know more than I thought I did.

During the past 30 years I learned a lot from people who had far more experience and knowledge than I possessed and through some trial and error as well got to where I am right now in my life. But it wasn’t until I started teaching others what I had learned I came to this realization.

Now you may not feel you need to teach someone else what you know is important but if you are good at something why not teach it to others. It may not have to be a school environment , it could be any setting you choose it to be. The need for mentorship , apprenticeship training , people with your experience in your field are needed to pass on their knowledge to the next generation.

There are teachers out there who have less practical experience teaching their subject than I am sure some of you reading this article have. I do not have a university education but I do have experience so it did count for something when I obtained the Bartending teaching position. By working full time in the restaurant business , teaching Bartending 1-2 nights a week gives the student not only the practical side of learning to make a drink but I can also relate to them what it is like working as late as last night on my shift in a restaurant. How much closer to the action can you get than that!

As far as the fear of speaking in front of others , talking of what you know is easier than you would imagine. Just be organized and let the class participate in the learning process rather than feel you have to talk for 3 hours. Encourage interaction and lots of questions. You have your own story that other people need to hear. Ask the student what they want out of the course you are offering.
Tell them of the money to be made or the travel involved. Highlight the positives of it because if they see you are still doing it , it’s believable. You can inspire , and open that door for someone that was up until they met you was previously shut.

You can look for an opportunity to teach others what you have learned over the years by looking at your local newspaper for openings, colleges are always interested in ideas for continuing education classes be it a whole semester or a full day course. Even advertise yourself and what you can offer. Not only is it fun but it provides an additional income as well. Most important of all though is by sharing your expertise you can make a difference in a person’s life and fulfill your own in the process.

You truly know more than you think you do. It is just time to believe it and start sharing it with others.

History

The first LAN put into service occurred in 1964 at the Livermore Laboratory to support atomic weapons research. LANs spread to the public sector in the late 1970s and were used to create high-speed links between several large central computers at one site. Of many competing systems created at this time, Ethernet and ARCNET were the most popular.

The development and proliferation of CP/M and then DOS-based personal computers meant that a single site began to have dozens or even hundreds of computers. The initial attraction of networking these was generally to share disk space and laser printers, which were both very expensive at the time. There was much enthusiasm for the concept and for several years, from about 1983 onward, computer industry pundits would regularly declare the coming year to be “the year of the LAN”.

In reality, the concept was marred by proliferation of incompatible physical layer and network protocol implementations, and confusion over how best to share resources. Typically, each vendor would have its own type of network card, cabling, protocol, and network operating system. A solution appeared with the advent of Novell NetWare which provided even-handed support for the 40 or so competing card/cable types, and a much more sophisticated operating system than most of its competitors. Netware dominated[1] the personal computer LAN business from early after its introduction in 1983 until the mid 1990s when Microsoft introduced Windows NT Advanced Server and Windows for Workgroups.

Of the competitors to NetWare, only Banyan Vines had comparable technical strengths, but Banyan never gained a secure base. Microsoft and 3Com worked together to create a simple network operating system which formed the base of 3Com’s 3+Share, Microsoft’s LAN Manager and IBM’s LAN Server. None of these were particularly successful.

In this same timeframe, Unix computer workstations from vendors such as Sun Microsystems, Hewlett-Packard, Silicon Graphics, Intergraph, NeXT and Apollo were using TCP/IP based networking. Although this market segment is now much reduced, the technologies developed in this area continue to be influential on the Internet and in both Linux and Apple Mac OS X networking—and the TCP/IP protocol has now almost completely replaced IPX, AppleTalk, NBF and other protocols used by the early PC LANs.

Technical aspects

Although switched Ethernet is now the most common data link layer protocol and IP as a network layer protocol, many different options have been used, and some continue to be popular in niche areas. Smaller LANs generally consist of a one or more switches linked to each other - often with one connected to a router, cable modem, or DSL modem for Internet access.

Larger LANs are characterized by their use of redundant links with switches using the spanning tree protocol to prevent loops, their ability to manage differing traffic types via quality of service (QoS), and to segregate traffic via VLANs. Larger LANS also contain a wide variety of network devices such as switches, firewalls, routers, load balancers, sensors and so on.[2]

LANs may have connections with other LANs via leased lines, leased services, or by ‘tunneling’ across the Internet using VPN technologies. Depending on how the connections are made, secured, and the distance involved they become a Metropolitan Area Network (MAN), a Wide Area Network (WAN), or a part of the internet.
