LCD monitors or Liquid Crystal Display monitors are replacing the old CRT or Cathode Ray Tube screens and are far superior in a vast majority of applications.
There are several advantages of LCD Monitors over the old CRT Displays. While LCD Monitors are compact and lightweight and consume less power approximately 20W whereas the CRT monitors are bulky and heavy consuming upto 150W. An LCD Monitor produces perfectly sharp images with perfect image geometry whereas in CRT the sharpness is limited and it tends to blur more at high brightness and with the aging of the tubes and suffers from geometric distortions.
LCD monitors have a consistent tonal scale and can display text with excellent contrast whereas the CRT monitors display strong bright areas which can cause other regions of the picture to dim and also has poor text contrast because of limited bandwidth.
LCD monitors do not normally flicker whereas a faint flicker can always be observed in a CRT monitor.
There are also some inherent disadvantages of LCD monitors over that of the CRT monitors. The contrast or the color changes with the viewing angle in a LCD monitor whereas in a CRT monitor it is always a consistent image irrespective of viewing angle. LCD monitors may cause motion blur and has a poor black on dark images. Whereas the CRT monitors usually portray motion well and also has good black contrast.
When viewing photos or videos on a LCD monitor it may appear flat and the peak brightness is limited by the back light. A CRT monitor displays movies/video/photos with a sparkle and life to images with very high peak brightness.
If LCD Monitor screens are damaged, it may develop stuck pixels whereas no such pixel based problems are present.
In LCD the natural interface would be digital e.g. DVI interface and the image can be sub-optimal with analog interface whereas CRT’s are naturally suited to analog interface.
On the basis of image-quality LCD monitor is best suited for technical/CAD applications and office uses such as large, detailed text-based but -non-critical color graphics while CRT still has the upper hand for high-end photography or art work and for television displays.
Unlike CRTs that are actively displaying the light through coated phosphors, an LCD actually takes white light and filters it to get the desired colors. To do this for each given pixel there are three sub pixels one for red, green and blue light. When the sub-pixel is off, the filter will block that particular color of light. When the sub-pixel is on, it will open the filter to let a desired amount of light through.
Today, many businesses use remote computer technology to either monitor their employees or sharing files and other important information. Remote computer technology is also used to keep tab on employees’ performance. But, before we discuss the benefits of using remote computer technology, let’s first understand this concept. When you access a computer from a distant location through a network connection, you are using remote computer technology. In other words, a computer that you can easily access from any other location by using an Internet connection is called a remote computer.
Automation is actually a process wherein the repetitive tasks that we do are being done by automated machineries such as robots and computers while communication technology refers to the methods and techniques that we use to send and receive messages across distances.
Most people will tell you that the only way to walk out of a casino a Millionaire is to walk in a Billionaire, but the fact is this is not the truth. It is only the easiest way to do it.
Are you as amazed by Computer Technology as I am? Everything from your smart phone to the GE PLC shows the progression of technological advancement over the previous decades. For instance the GE Fanuc series of component parts is the latest in a long line up of Computer Technology component parts that demonstrate this great advance in technology. So what can we expect in the future years in regard to even further computer advancement? It’s very difficult to gauge what will happen in the upcoming years but I think that we can safely assume that technology will continue to move forward at a rapid rate. We all know how amazing the advancements in Computer Technology of 10 over the previous 50 years. For instance the concept of a personal computer would’ve been foreign to someone in the 1950s and yet is extremely common today. So what can we expect than 50 years time that would be unimaginable today? Will smart phones play an even larger role in our lives than they currently do? I think that this is one area that we can definitely bank on as smart phones have become indispensable to those who use them. I think that we can also safely assume that technology as a whole will play a larger part of people’s day to day lives in the future because suddenly the trend has been heading this way for the last few decades. 50 years ago if very few people came into contact with computers now almost everyone is in constant contact with them so this trend will likely continue.
Since the dawn of the internet there have been several different mediums that have made communication even more and more convenient. Today, these mediums span over the internet alone as software and hardware utilize internet capacity in order to generate communication over large geographical spans, no longer limited to particular locations. As long as your computer is capable and has internet access then you are good to go.
NASA has always been in the forefront of ground breaking technology for many years now, and they are not slowing down anytime soon. Even as the United States economy has shrunk the budget of the agency, it has not let this challenge to get in the way of progress. NASAs missions include various trips into space and specifically the Russian controlled space station. Ever since the agency came into existence, they have focused on astronaut safety before anything else. The value of life amongst the agency is high, and no mission’s goal precedes it. There have been accidents in the past where brave astronauts have lost their lives. We have even seen instances where civilians on missions have lost their lives like in the case of shuttle Columbia. In order to maintain the health of its astronauts, the agency strives to both develop and adopt technology that helps it monitor the health of its astronauts.
Do you think you’ve already seen everything on our planet? And traveling even to the remotest parts of our world doesn’t excite you anymore, and then space tourism is the way to go for you. No, I’m not kidding, space tourism is an option increasingly being chosen by travelers. The only drawback is that they are somewhat unique in terms of costs involved and timing. Many people believe that buying tickets to travel to space and back is a futuristic idea and still only a concept.
NASA on Friday said fear of failure should not hold back its mission to test the boundaries of human space exploration, as the agency marked the 25th anniversary of the Challenger disaster. Seven crew members died aboard Challenger on January 28, 1986, when a booster rocket failed 73 seconds after liftoff, triggering an explosion of the space shuttles fuel tank.
Communications is very important now days, many people are seeking for ways on how to reach their loved ones who are thousand miles away. Before, the only way to communicate with our loved ones across other country is through our post mails, we write them letters on a piece of paper and enclosed it on an envelope and send it on post office for stamps and delivery. This process usually takes days, weeks or even months depending on the location of the destination.
