Basics of Computer Network Administration and What You Can Do

Updated on September 7, 2016

Who is the Network Administrator?

A network administrator is basically the person who manages the computer network no matter how few or plenty the users are. Network administrators are in charge of network hardware and software maintenance. He sees to it that the servers, cables, routers and all devices are working properly. If things go wrong, he is in charge for the checking and giving solutions to problems. He also answers all queries from the network users and addresses any glitch that happens.

The most important role of a network administrator is the security of data. He has to watch out for hackers who try to manipulate your data and send virus to it. One thing more, he has to have a backup of all the data so that in cases of disaster, it won’t be a big issue. He will only recover the data from his backup and things will be back to normal in just a short while. I have experienced a lot of loss in my life and losing my files and the office files is a tragedy. My boss did not talk to me for days and we had to start retyping and redesigning forms. The most interesting part of it was we were running out of time because of a set deadline. A lesson learned, I always back up my files using flash drives, CDs or DVDs. You do not need to rely directly to the network administrator to do this job especially on files you are working on.

Basic Computer Network Troubleshooting

When your computer breaks down or have simple issues especially regarding your network, you can just check it on your own. For small networks which you installed your own, you can contact the customer support team where you bought your networking device. If your router is a Tenda Wifi Router you can contact Tenda Tech Support through their website found here: To do simple checking yourself before contacting for support, here are some basic skills you can do yourself.

1. Are you connected?

First thing to check is if you are really connected to the network. Check your cables if they are plugged in. Use the troubleshooter to check the problem and take note of the errors that will appear and that is the time you message the network administrator or technician.

2. Restart the Computer

I have tried this several times and different computer problems get solved simply by restarting the computer. Sometimes, it is just the computer itself and you need to reboot.

3. Computers that Don’t Turn On

There are times when we turn the computer off before leaving the office and it just works fine. When we get back the next morning and turn it on it just doesn’t. Check the cables especially if it is plugged in the power socket. If it is plugged in and still doesn’t turn on, listen to the sound of its fan if there is. If it is running but the monitor is still black, check if the monitor cable is plugged in properly or if it is powered on.

4. Your Computer is Invisible on the Network

Some causes of network invisibility are twisted cables, or they are eaten by insects or rats. Check for any of these and ask assistance to the technician if you see any.

5. Check Other Users if They Have the Same Problem

You are a part of the network so you are not alone. If you are having problem especially with internet signals, try asking your colleagues if you have the same situation. It might not be your computer at all and the signal is really not working for the network as a whole. Same with other errors you receive, check your companion’s computer if they are receiving similar circumstances and inform your network administrator immediately.

Computer Network Security at a Glance

An individual computer can easily be secured because when you turn it off and leave it, nobody else can steal your files unless they get inside your house or office and use your computer. In a network, especially those who have several users, files are not secured easily. Hackers can easily break in and copy your files through an open user. That is how fun and dangerous the technology is. Read on and check some tips we can give you to secure your files in the easiest way you can contribute to your network.

1. Passwords are not for public use

When creating for passwords or security keys, you might as well store it inside your head, memorize it and do not save it on your phone or write on a sticky post and post it on your wall. Be secretive when it comes to passwords and use a more complex password rather than common details about you like last names, birthdates, or initials. You may use this in a combined form for example your name then birth year and add another set of characters like your initials or your wife’s.

2. Do not share your account

Your account in the network is for you only and should not be shared to any other user or colleague. If they can’t access something through their account, you might as well advise them to talk to the administrator.

3. Do not manipulate any software

Do not install or manipulate any software installed in the system as it will affect not only your unit especially if it is from another networking device or similar to this. Always ask permission when adding and removing programs. Also, do not change a printer setting if not permitted by the administrator.

If you want to contribute in the maintenance and security of your computer network, just follow these simple tips so as not to destroy all the files including yours in the network.
