Computer Networking Technology Continues To Speed Forward

Who remembers the Commodore 64? Released to the public in the early 1980s, the Commodore 64 was the most popular computer on the market for a number of years. In fact, it is still the highest-selling single computer system to this day, with an estimated 17 million-plus units sold.

The Commodore 64 featured revolutionary graphics and sound for a machine of its time, and for that reason was widely popular for playing games. It also had a built-in data recorder known for its slow processing times and little storage space. While a floppy disk attachment was eventually released, it did little to increase storage capacity.

The networking capability of the Commodore 64 and other early single-user computer units during that time was minimal. A dial-up modem soon became available, which allowed users to connect with public bulletin boards to access early online games. This also enabled users to chat and message each other, basically setting the stage for what is known today as the Internet.

Computer Networking

Development of computer networking technologies and early versions of the Internet began in the late 1950s, and were in use by the military and science communities by the following decade.

During the early days, machines with the same capabilities as today's desktop computers were so large they required multiple floors in order to operate. The compact size of today's computers can be credited to the development and evolution of the microprocessor, which allows communication to take place at lightning speeds through conveniently small devices.

Networking Becomes the Norm

In the 21st century, computer networking has become part of our everyday lives. The Internet has been in widespread use for around 20 years, allowing us to instant message each other, send large documents, share photographs and have the equivalent of a world-class library at our fingertips. These things have all become routine in our high-tech world.

Whats Behind the Network?

Simply put, a computer network consists of multiple computers that interconnect. A Local Area Network (LAN) is a computer network residing in one locale, such as a building, an office or a campus. A Wide Area Network (WAN) is a computer network that is spread throughout a large geographical area. The Internet can be considered the largest WAN on earth!

The actual connections and cabling within computer networks often go overlooked. This is not the glamorous side of computing by any stretch, but it is a networks lifeline. When networking was in its infancy, information transfer was very slow due to the fact that only one piece of information could be transferred at a time. This could also be attributed to the limitations of the cabling, which was basically telephone wire at that point.

With the advent of packet transfer technology, multiple pieces of information were able to be switched back and forth simultaneously. This revolutionized the speed at which computer networks operate. Along with the computing technology came an upgrade in the actual network connections; the cabling.

We now have Cat5e bulk cable, which provide an amazing amount of bandwidth for information transfer compared to original network cabling. And for jobs requiring faster speeds, Cat6 bulk cable provides even more bandwidth. Fiber cable is used in the largest and fastest networks.

Just like networking, technology is not slowing down. Weve come a long way in the last 20 years of personal computing. The prospect of what's to come is exciting to ponder.

Know What is Running on Your Computer and How This Information Can Help Speed Up Your PC

One of the things that happens to many Windows users is that their computers end up slowing down over time. Much of this is attributed to virus issues, malware problems, and registry errors. There are programs to deal with each one of those. One problem that a user causes on their own is not knowing what programs are running on their computer at all times.

To find out what programs are currently open and running, the easiest way is to hit Control + Alt + Delete. Push these and hold all three down at the same time until you see a dialogue box come up. In that box click on "Processes". This brings up a list of the applications and programs that you are currently running.

Before you do anything be careful that you don't accidentally shut something off that is actually needed to keep Windows running properly. If you do shut something off, you will have to reboot to fix the problem.

Sort the programs by their ram usage to see what the biggest computer speed hogs are on your machine.

You might notice quite a few applications are in your active RAM that you aren't currently using. Some of the usual ones are Microsoft Office running in the background or the iTunes Updater. You can end these processes to free up some RAM since you don't need these things running all the time.

Another important reason to look to see what is running is because something viruses and malware will show up here. You can see them open and running while using your computer. Many have become smarter about not showing up in this list but some still do. At times these can also be caught by looking at your bandwidth to see if these programs are sending or receiving data.

Once you understand what is going on with your machine, you will be able to maintain it much easier and help it run more efficiently.
