Disadvantages of computer networking

Answer 1

1. Breakdowns and Possible Loss of Resources One major disadvantage of networking is the breakdown of the whole network due to an issue of the server. Such breakdowns are frequent in networks causing losses of thousands of dollars each year. Therefore once established it is vital to maintain it properly to prevent such disastrous breakdowns. The worst scenario is such breakdowns may lead to loss of important data of the server. 2. Expensive to Build Building a network is a serious business in many occasions, especially for large scale organizations. Cables and other hardware are very pricey to buy and replace. 3. Security Threats Security threats are always problems with large networks. There are hackers who are trying to steal valuable data of large companies for their own benefit. So it is necessary to take utmost care to facilitate the required security measures. 4. Bandwidth Issues In a network there are users who consume a lot more bandwidth than others. Because of this some other people may experience difficulties.

Answer 2

A computer network is hardware and software that enables computers to send data to each other electronically. Non-networked computers can't send data to each other; it is necessary for a person to physically move the data from one computer to the next. We used to use floppy disks for this purpose (and we called it "sneakernet", referring to the shoes used by the people running the floppies around the office) and now we use CDs and USB drives.

There are many advantages of computer networks. Remember that the internet is a computer network! But we're talking about disadvantages here, so here are some categories where computer networking could be a problem.

Information Security

If a computer is connected to a network, it is much easier to send any secret information stored on that computer to some other computer on the network.

Vulnerability to Remote Exploits

If a computer is on a network, not only can it send information to any other computer on the network, it is also able to receive messages from any other computer on the network. Because the people who write computer software are human and make mistakes, sometimes the software will have bugs in it that allow someone on a different computer on the network to send data to the computer with the buggy software in such a way as to attack it - make it lock up or crash, make it slow down, or even take control of it.

Rapid Spread of Computer Viruses

Computer Viruses are programs designed to take advantage of buggy software to spread copies of themselves. When computers are connected by a network, the virus can spread itself electronically, at computer speeds. Without a network, it can only spread as fast as the sneakernet can operate (as fast as people can carry disks between the computers).

Configuration Management

Sometimes (such as in medical equipment) it is important for a computer's software configuration to be predictable and stable. If a computer is connected to a network, it's easier to download and install software from the network onto the computer. This includes automatic software updates, so this can happen without any human intervention. If the new software hasn't been tested, it could cause unpredictable behavior and possibly endanger lives.

Computer Networks can Fail

Computer networks can be so powerful and useful that it is common for them to be used for more and more purposes. A network might start out as a small convenience, but later may become mission-critical - the computer can no longer do its job without a properly functioning network. If the network was originally only a convenience, there may not be any attention given to what might happen if the network were to fail, even after the network becomes indispensable. All of the computers in an office building might become completely useless if a single network component fails.
