Lets Know of Computer Technology - Is it Good Or Bad?

The 21st century has been the age of so many technological breakthroughs and advances, technologies aimed for one purpose and that is to make the lives of people better by helping them become more efficient in their work. One such technological breakthrough is computer technology.

Computer technology has grown in great proportions starting from a computer with a size that of a room to a small well-designed palm top computer. Computers nowadays have become an indispensable part of the lives of people, especially at work, at companies, businesses, schools, offices and even in homes.

It has made the world smaller, but has it made our world better? It would then lead us to ask whether computer technology is good or bad. Now let us try to look at first some of the bad effects. With the advent of computers and with the internet it has become easy to access pornographic sites, children are more exposed to explicit content; some students would lose focus on their studies as they play computer games. The number of obesity cases has increased and it has been attributed to too much computer activity that led to less physical activity among a number of people.

On the other side of the coin, computers have opened a whole new world of possibilities. It is now easier to gain information on world events; you can even find a job in the internet; you can spread advocacies to a vast number of people all over the world; and most importantly it is now easier to be connected with one another even if you are on the other side of the globe.

Computer technology, just like any other material on earth has been created with a common good in mind. Just like a knife, it has been made to cut and slice food to speed up cooking time for people but it can also be used to kill people, and you cannot ban the use of knives in order to stop killing. And so you can't blame computers for the problems it may have caused for it is the people who use them who caused the problem. It has disadvantages and advantages that must be taken into consideration.

But the problem is not computer technology itself; the problem resides on the people who use it. Computer technology is generally good for it can bring in a lot of good if it is used properly, but can do great harm if used unwisely.

People have choices on how they make use of earth's resources, and that choice will determine how certain materials will affect people, be it good or bad.

Dish TV Programming Channels from MPEG 4 Technology

Dish TV programming channels are aired on MPEG 4 Format. Because of this viewers of satellite televisions are getting distortion free images on their television screens. The programs are broadcasted straight away from the geosynchronous satellites directly to the viewer. This is yet another reason that has made satellite television quite popular among people.
About MPEG 4

MPEG 4 is a patented technology that was introduced at the end of the year 1998 and it soon gained immense popularity. This format is used mainly to stream internet media and later on it was introduced for streaming television signals. Today MPEG 4 is recognized as a standard video and audio coding format. MPEG 4 is quite similar to MPEG 1 and MPEG 2 since it shares several features from these two formats. New features have been added later on for make it capable for 3D rendering. The well known codecs such as DivX, Xvid and Nero Digital have now become a part of this amazing compression format.

Previously this audio video compression format was aimed mainly at low bit-rate video communication. But soon the scope of this compression technology got expanded and now it has become the primary tool for multimedia coding. This format is extremely efficient across a wide spectrum of bit-rates, which is from few Kbps up to tens of megabytes per second (Mbps). MPEG 4 is known for enhancing the efficiency of coding and it is even capable of encoding mixed media data such as audio, video and speech.

Since this amazing audio and video compression format is used for streaming television signals, therefore dish TV service providers have decided to adopt this technology to offer maximum TV viewing pleasure. For this purpose the service providers of satellite television have introduced newer receiver models that are compatible with this format. One such receiver model is ViP 622 HDTV DVR receiver.

About ViP 622 HDTV DVR receiver

This is a unique satellite TV receiver that supports both MPEG 2 and MPEG 4 technology. This is a High Definition Receiver that has two tuners named TV1 and TV2. it has a built-in 120 gigabyte hard drive that is capable of storing 100 hours of television program recording. This device allows you to operate it in two modes. One is the Single Mode and the other one is Dual Mode. In single mode you can operate its two HD tuners from a single remote and in dual mode, you can record a TV show while watching another channel.

In this receiver you will be getting two remote controls in which one is a regular infra-red based and the other one is UHF or Ultra High Frequency based. The UHF remote will allow you to control your ViP 622 HDTV DVR receiver from 200 feet irrespective of any obstruction. And the regular IR based remote is even capable of controlling your TV and VCR.

Satellite TV is all about sophisticated technologies. You are getting crystal clear picture and rich surround sound on your television set. Add a feature packed satellite receiver with that and the outcome will be something that can be described only in one word - marvelous.

Incredible of Incandescent Lights Versus LED Lights

LEDs are the latest craze when compared to incandescent lights. For one thing, they are much more energy efficient. LEDs have a much longer life span. As a result, incandescent bulbs are quickly becoming a thing of the past when it comes to performance and output. So let's shed some light on this issue - no pun intended.

LED lights originated in the 1960s and are basically a semiconductor light source or diode. When a diode is turned on, electrons recombine and thus release energy in the form of photons. In an incandescent bulb, on the other hand, a filament is heated to produce the light. The filament will eventually burn out and the bulb does get hot. LEDs can last as long as a standard transistor and they produce light through electrical activity instead of heat. The average lifespan of an incandescent bulb with continuous use is six hundred hours, while the lifespan of LED lights is approximately ten thousand hours.

Today, LED lights do a variety of jobs and can be found in all kinds of devices. Unlike fluorescent or incandescent bulbs, LEDs are able to place light in a single direction much better and smart designs can be achieved with their directional output. Strips of LED lights can be placed in staircases, hallways, on the outside of wall units, etc.
Special designs have been made specifically for outdoor use where waterproofing is a concern and outdoor applications include lighting for walkways, gardens, buildings, and even bridges. The diversity of applications can be seen in the automotive industry as replacements for traditional indicator lights and daytime running daylights. LEDs are even replacing the incandescent traffic lights.
LEDs are brighter, longer lasting, and much more energy efficient when compared to incandescent bulbs. It's no wonder they are the latest craze.

If you're looking for lighting solutions that incorporates the latest LED know-how, Sylvania, Streamlight, iLight Technologies, and Hella should be considered.
