Variant Types Of Computer Networks

A computer network is the practice of linking two or more computing devices together to exchange information. Networks are built with a mix of hardware
and software. This network is to share services and communicate via a communication link.

A computer network is very useful in a business. Most companies have over time more of a team and is often very beneficial to the network for all computers in the office. Local Area Network (LAN) equipment to your company. It’s about sharing and exchange different types of information as possible. If there are networks of computers, you hear these reasons.

There are different types of computer networks. A computer can be as simple as connecting two computers or a computer and a printer, or it can be very complex, connecting millions of computers and peripherals. Here is a list of different types of equipment.

The smallest type of network is a Personal Area Network (PAN). This type of computer network to connect a computer to a series of devices. These devices may include, but are not limited to, printers, PDAs and phones. Typically, these are very close to a computer. a Local Area Network (LAN) is a network of small geographical used.

How Do Viruses And Worms Affect Your Computer

Also, unlike viruses that most commonly infect an individual computer, the worms usually attack a computer network. A computer network functions by using a collection of servers and routers. This is what the internet is comprised of. A server is like a PC but has more speed and storage and a router is a server with specialized functions, it directs traffic through the network.
PC Security – Worm Viruses, Deadliest of All

A virus attacks the unit used to run programs on the computer called the central processing unit or CPU for short. It does this by running programs and being constantly busy, so that none of the functions you select can be opened. Similarly, this is how a worm functions on a network. The routers rely on memory and processing time (similar to the CPU functions). These are attacked and as a result the network drastically slows down.

Worms carry payloads which are comprised of other types of malware, backdoor installations or spyware. Spyware is a monitoring program that can keep an eye on activities on your computer and backdoor programs set up hidden access points used by hackers to steal your information or send spam.

My Doom sent out at the beginning of 2004, was the fastest spreading worm to date. The worm came in the form of an email with the message “andy; I’m just doing my job, nothing personal, sorry.”

Although the culprit was never found, its intended victim is thought to have been a software company called Santa Cruz Operation or SCO for short.

When a person opened this email, the worm was programmed to overwhelm SCO’s website with traffic. The worm spread through the internet and caused a massive slow down.

For the individual computer, the worm’s payload is more serious because it allows ports to be opened on the computer where hackers have access to steal or delete information. In addition, a payload may come with a program to attack your antivirus software and disable it.

De worming

Using firewalls will help protect your computer. Firewalls reduce traffic and hide your computer. In this state, you are less likely to be attacked by worms spread over the network.

Be careful not to open suspicious emails and if you don’t know the person or get and unexpected email don’t open it. If you find your computer is slow and reboots by itself or the internet is sluggish, you may have been infected. Try running antivirus software to check it out. If that doesn’t work, try to manually removing the virus. Information as to how this is done can be found on the internet.

Pc Enclosures Protecting Computers On Factory Floors

With the price of standard computers dropping, this puts computers in the reach of everyone, most homes have at least 1 computer and 1 laptop, with the low cost and availability businesses are now using them to monitor and control the production on factory floors.

However we all know that the standard computer is best suited in an air conditioned office, so as soon as they are introduced to factory floors that are dusty, dirty and full of grease, problems occur, with lost data and this can result in lost production time.

To combat this, some companies either build custom offices on the factory floor at a cost of thousands to have an area that is safe and free from relevant dust contamination or they purchase special industrial computer cabients that offer a safe protective environment for the computer to run without being effected by any dust, grime or fluid that is in the surrounding area. The computer enclosure is a more affordable solution, as it can be relocated if the production line is increased or reduced, were as the office would have to be demolished and rebuilt!

Industrial computer cabinets are cooled depending upon the application and the extreme temperatures, there are solutions to cool an enclosure to -30 degrees and there are solutions to heat the enclosure to +60 degrees Celsius. Air cooling units are also available, however they have moving parts than do wear out over time, there are options to maintain a ambient temperature inside the cabinet even if the external temperature range is to variable.

One solution to use in large temperature ranges, is a cooling tube, these run on compressed air and once fitted to the industrial computer cabinet, are set to the desired internal temperature, for example 20 degree Celsius and it does not effect the hardware if the external temperature drops to -20 degrees or 140 degrees Celsius, as the internal temperature is a steady 20 degree C. These cooling tubes have no moving parts, so there is nothing to wear out and they will certainly pay for themselves.

This is why many general manufacturers such as Ford Motors, Vauxhall, Paccar Trucks, and SCA Hygiene use computer enclosures, to protect their computer hardware and to help control production.
