Plasma TVs – Pros and Cons

Are the Plasma and LCD TV the same? Actually they are not, and very different in many ways. Pricing is a key factor but there are other things as well. We will mainly focus on the features of the Plasma TV, which will also help us understand LCD televisions. The good thing about Plasma TVs is that they have a better contrast ratio resulting in better representation of color. They are also better at rendering the color deep black, resulting in better picture that is aided by better color depth. The increased response time and superior motion tracking results in very little lag in fast moving images. Plasmas also come in bigger sizes than LCDs and cost less as well. With all these good points, the Plasma TV seems to be the obvious choice for consumers. Well, not quite. If you accidentally leave your screen paused for a long time an effect known as burn-in can occur. The image that was paused leaves an impression on the screen. In addition to this, Plasmas consume more power and produce more heat making them less environmentally friendly. They also suffer from screen glare so the room cannot be well lit if you are to enjoy the image. Finally, mounting a Plasma TV on your wall can be quite an effort as it is very heavy, requiring a lot of support to...

Use of Environmental Technology

Technology has gone through several phases of usefulness. Initially, technology was used to fulfill needs, in order to ease the load and now, it is used to provide luxury. This refers to technology in any area where humans and equipment interact. Over the years, the use of technology has meant the destruction of the environment, either by plundering natural resources or by pollution caused by the byproducts of manufacturing and the disposal of garbage. This has led to a move towards greener technologies. Mostly spearheaded by recycling efforts and reclaimable energy, the movement is gathering pace. Many companies that produce electrical goods like mobile phones and computers are resorting to reusing or recycling material in their manufacturing process. This has benefits on many levels such as being cost effective, using less natural resources and producing less pollution. Reclaimable energy is becoming more of a necessity as many businesses are fighting to keep operating costs down. The use of solar energy and natural heating and cooling methods as well as natural lighting methods are helping both businesses and the environment. However, none of these methods is 100 percent effective, as technology to support this does not exist. Recycled products still have to use a fair amount of natural resources and reclaimable energy has to be propped up with more traditional methods as sometimes they just do not have enough juice....

The Benefits and Disadvantages of ITIL

The Information Technology Infrastructure Library (ITIL) is a set of concepts developed by the UK government’s Central Computer and Telecommunications Agency (CCTA) to standardize IT management practices. Initially published in 1989, it has gone through a few iterations, namely ITIL v1, ITIL v2 and ITIL v3, its most recent version released in 2007. The current version is comprised of five volumes that focus on Service Management. As with any type of guidelines, there are proponents and opponents who constantly argue about ITIL. The proponents argue that ITIL offers many cost saving measures, which in the current context of the recession makes enormous economic sense. It also helps to organize and manage IT departments. The biggest factor in its favor is that ITIL has been implemented in various parts of the world and has been proved to work. However, there are many disadvantages to these guidelines as well. One problem is the perception that it is the “be-all and end-all” of IT solutions. This is worrying as ITIL is not yet fully comprehensive. It is also stuck to rigidly by IT managers where it has been implemented. This has caused dissention among lower ranked IT employees who are of the view that certain rules should be bent and that other techniques should be given a chance to have an optimum management system in place. The fact that the ITIL’s lack...

How 3D TV Technology Works

The future lies in 3D. The runaway success of James Cameron’s hit movie Avatar has brought the thrill of 3D back to the masses. As usual, when one person has put in the hard work and brought technology into the limelight there are plenty of people who find ways to capitalize on it. The latest endeavor on those lines is to bring 3D to the television unit in your home. While there are many methods in which this feat can be achieved, this article focuses on three LCD-based technologies that we are likely to see vying for our attention. Philips has been pioneering research in Lenticular viewing to bring 3D to your home. This technology is available right now and uses a lens attached in front of the TV to achieve the 3D effect. So, what is the advantage? You do not have to wear those silly glasses to watch a program in 3D. What is the disadvantage then? You have to sit in a particular spot directly in front of the TV to get the full effect, which means that not more than two to three people can enjoy this technology at a time. Hyundai seems to have the most feasible idea, where TV supports 2D and 3D viewing. You will however, have to wear polarized glasses to see anything in 3D. This LCD TV is expected to...

The Difference Between Hackers and Crackers

When the issue of IT security is raised, two words come to mind – Hackers and Viruses. This article concerns the former. The term “hacker” has become the widely used term for anyone who breaks into a system. However, the term should be used appropriately as it describes a person with “honorable” intentions as opposed to a “cracker” who is up to no good. True hackers are basically puzzle solvers. They see security systems as challenges to be overcome and set about getting through its defenses. They are technically well-versed and enjoy breaking into and infiltrating systems just because they want to and not for malicious reasons. In essence, they embody the quote attributed to the famous English mountaineer George Mallory, who in reply to the question “Why did you climb Mt. Everest?” replied, “Because it’s there”. Hackers break into systems to expose their vulnerabilities and thereafter document the process so that others can learn from them. This actually benefits the IT community as security holes that are undiscovered can be blocked due to these findings. Hackers engage in their activities mainly for the challenge and also for the credibility gained from their peers for beating the system. Crackers on the other hand do not have any honorable intentions at all. Looked down upon by the hacking community, they engage in activities like stealing credit card details, destroying data...
