Computer Monitors

Computers and the Internet have changed and continue to change the world. The computer is the vehicle that is introducing the world to technological advancements and medical and social achievements. Computer monitors are the windows of this new world and they continue to improve in quality and performance. The computer monitor of ten years ago is not the same visual display unit it is now, but it’s still a piece of electrical equipment which can display a wide range of images from the video output of different computers, without creating a permanent record. The display device used to display images today is a thin film transistor liquid crystal display also known as TFT-LCD. The older monitors used a CRT or cathode ray tube.


Measuring computer monitors is a bit confusing. The measurement is based on the CRT television method, which was used when round picture tubes were popular.

They were circular, so they only needed a diameter measurement to describe the tube size. When CRT tubes were manufactured as rectangles this method was still used, so the distance between two opposite corners is given as the screen size, even though it does not take into account the aspect ratios differences of monitors with the same diagonal size. The shape of a diagonal area decreases as it becomes less square, so the measurement system is a not accurate, in terms of square inches for monitors with the same diagonal size. Another issue with screen size is the size of the imaging element, which is distorted by media advertising campaigns. Viewable size is more important than measuring the image element size, which can be hidden behind the case’s shroud.


Image technology continues to improve. TFT-LCDs are the most popular monitors, the old passive LCDs had a slow response time and the contrast was poor. They started to be replaced in the mid 1990s. Other types of visual displays include the Penetron and the Plasma Display along with the old CRT.


The LCD is light, compact and rugged and there is no geometric distortion, but it has a low contrast ratio, uneven back lighting and slow response times, which can cause ghosting. The Penetron Military Aircraft Display has high contrast ratios and is extremely sharp, although there are only four color displays. The Plasma also has high contrast ratios and a high speed response, excellent color and a low black level, but it has lower resolution on a large screen and there is a noticeable flicker when the display is viewed close range.


Today’s computer monitors can display an infinite number of colors by continuously changing the intensities in the RBG color space, which is the red, green and blue analog video signals. New connectors are replacing both analog and digital signals with digital only video signals, which have integrated data and video connections. Other new features include multiple monitor capabilities, which can show the identical image called mirroring and extension monitoring, which shows different images but it does require extra hardware and software support. There’s no doubt than computer monitors will continue to improve in quality as well as functionality. The touchscreen technology is opening the doors for another giant leap in the virtual display industry.

This is a pretty amazing idea, as once upon a time people consideration that this could be completed only with the use of a television set. Much momentum has been gained with space communications, and this is truthfully what a lot of people would prefer.

Watching satellite TV on your computer is distant improved than using a television set, as that will require the installation of a dish or antenna. This procedure could prove to be extremely lengthy and as well complicated. With the PC, all one wants is a card to install the viewing software or PC satellite TV software, and a sound card, with a high-speed broadband link.

Setting up a dish will as well prove to be extremely luxurious for most families, what with the cables and extra operating cost for equipment.

The extra drawback with the dishes is that they will have to be placed in the right way, consequently that the signals are ideal. It has to be placed consequently that bad climate conditions will not involve the transmissions and viewing knowledge.

To watch satellite TV on your PC, you will have two options to do consequently. First here will be the hardware choice, the PCTV cards and the extra software choice, PC satellite TV software. The satellite TV signals can be decoded and received with the aid of the PCTV cards. This has to be installed on the motherboard of the PC. A USB port can be used to attach the outdoor cards. The software choice is simpler as it now requires you to run the installation completing file.

A good Internet link is wanted for equally options. If you desire the TV feeds to be of high quality, then the Internet link has to be at slightest 512 kbps. The pictures will be sharper and improved if broadband is used, although a dial up link can be used for this reason. While shopping for PCTV cards, you will as well have to check if the necessities of installation are met by your PC.

It will be particular that here are sure configurations necessary for the PC such as the memory and RAM.

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.
