High speed internet access, also known as broadband internet, is a high data-transmission rate internet connection. High speed internet has revolutionized the way that people utilize the internet. Before broadband internet, people spent more time downloading content than enjoying it.

The fastest that dial-up internet access can deliver downloaded files is at the rate of 56 kilobits per second. High speed internet, on the other hand, typically transmits at nine times the speed of a conventional dial-up modem. There are also broadband service packages that can transmit up to 20 Megabits per second.

Broadband internet access refers to DSL (digital subscriber line) and cable modem access. DSL is the most commonly used high speed internet, with cable running a close second in terms of popularity. There is also satellite internet access, but there is a high latency problem caused by the distance the signal must travel to and from the satellite. Currently there is also a new service called power-line internet that is being tested. This internet service may eventually allow high speed internet data to travel along standard high-voltage power lines. However, this data transmission system has several issues that will need to be resolved before the feasibility of power-line internet is determined.

High speed internet access became an extremely rapidly developing market in many regions in 2000. Studies found that broadband internet usage in the United States grew more than 24% between 2000 and 2003. One of the challenges of this age of broadband is the ability to provide high speed service to customers located in rural areas. This is because in urban areas service providers are easily able to recover the cost the new equipment required to offer broadband. For this reason, many rural inhabitants still use dial-up or ISDN, which typically delivers data at up to 128 kilobits per second.

In some markets, especially those outside of the United States, there are some internet service providers that are taking advantage of the current lack of industry definition as to what constitutes as broadband internet. Currently, the Organisation for Economic Co-operation and Development has defined high speed internet access as 256 kilobits per second in at least one direction (upload or download), though average consumer broadband speeds far exceed this rate of data transfer. Thus, some internet service providers take advantage of lacking industry standards and market lower bitrate connections as high speed.

With the innovation of high speed internet it has become possible for users to download and watch videos and music files in just minutes, if not immediately. Anyone that’s used dial-up to download these larger types of files knows the frustration of waiting hours for a download that may never even complete. Without broadband internet access, the popularity and convenience of peer-to-peer file sharing would not have been possible.

As the rate of data transmission increases, the market expects that streaming video and streaming audio services will become increasingly popular. Interestingly, video encoding formats such as MPEG-4 are making top quality video streams accessible at even lower bandwidth rates. Innovations in video formats are converging with the increasing end user bandwidth speeds to provide unprecedented video access over the internet.

As data formatting innovations combine with increasing access of high speed internet to users around the world, we will continue to see improvement in the delivery of various media types as well as improved connectivity and communication, in general, between people all around the world.

Antenna -Tell Me If The Picture Is Clear
posted by: admin in Satellite TV on 01 28th, 2009 | | No Comments »

Was it really so long ago; now it seems like another life altogether. Pieces of our lives seem to disappear at a rapid pace; and what’s even more scary is that you look around and you can’t even see a trace of the past. Even people whose economic means won’t allow them to participate in using the new gadgets; are forced to stay current, because manufacturers no longer produce the parts they need to use their old equipment.

Do you remember that time in your life. You were young, sitting in front of the TV; hopefully you were watching your favorite show, but if there were others in the room, then you had to watch what the majority wanted to see. You’re sitting there with your eyes glued to the screen; then suddenly, snow. Yes, it starts snowing on your screen. I guess the more common name for it is static; either way, you and nobody else can see the picture on the TV screen. You were asked, or maybe told, to go outside. So why are you going outside, because that’s where the pole is. And why do you need to go to the pole, because the pole has the antenna on top of it. Yes, the antenna, maybe the second most important factor between a good picture on screen and static. The most important factor, well, that would be electricity.

I can’t complain too much, our antenna was on a pole. I spent many a day in all kinds of weather, twisting and turning that pole; trying to bring the picture back to the TV screen. But some people had it worse. A lot of people had antennas on top of their homes; so every time they lost reception, they literally had to climb a ladder, to get to their antenna. So what was this marvelous piece of equipment that kept TV alive. An antenna is basically described as a group of conductors that transmit an electromagnetic field in response to EMF signals. Even though we can’t see these signals, it’s obvious they were happening, that’s why the TV reception reacted to me turning the pole. And it also makes sense that a lot of lost reception came during bad weather. Apparently the bad weather was blocking the signals from reaching the antenna, so that resulted in static on the TV screen.

Even though we don’t see a lot of those antennas, many of us grew up with, they are still around. They’ve lost their homey, nostalgic appeal and now, like everything else, they have gone high tech. You don’t have to go far to find the new breed of antenna. As you notice homes in your area, you will no longer see the old fashion antennas, but you will see these devices attached on the side and even on top of the homes. These are called satellite dishes; and these are the new antennas of today. The satellite antenna is more powerful than any of the past. They’re able to pull in signals far beyond our imagination; and provide the user with better reception and more channels then one would’ve ever thought possible for a television.

IT Focus – Careers and Redundancy
posted by: admin in Personal Tech on 01 26th, 2009 | | No Comments »

Once you have become an IT professional your life becomes consumed with IT. Long hours of programming, support or planning and irate spouses become your life.

There seems to be no way out of the IT circuit and the rule is diversify or die. What was popular today is gone tomorrow and to keep employed you are always having to surf the crest of the IT wave with the latest advances in technology, languages and software. Diversification does not mean you have to rely solely upon IT courses and books, there are other pursuits that can complement your IT career whilst providing an escape route in times of fatigue or facing vocational redundancy. Here are some ideas:

Instead of learning the latest computer language try learning a new human language. A new language such as Spanish, French, Chinese or German will give you the skills to program applications that cater for people who speak those languages. Your new human language will allow you to export your skills to other countries providing you with the ability to travel and should your skills become redundant in one country they more than likely could be utilised in another country. You could end up providing translation services for documentation or applications or even just working as a translator.

Writing articles about your job gives you skills in writing and publishing. Perhaps IT journalism is your next step, writing for an IT magazine or writing a book on a system you know well.

Courses in speaking or training could lead to a job in training IT professionals where you would probably get free training yourself in the latest products.

I have a friend who started growing lettuces on the side, I was amazed at how much he had done when he showed me tables of hydroponic lettuces growing on his 6 acre property. His philosophy was “in the future people will most likely not need Oracle but they will need food”. A radical departure, but he is beginning to pull a living from his venture and there is no need to expensively upgrade a lettuce to the latest version.
