What Is Dialup? What Is Fibre Optic? What Is ISDN? What Is ADSL?

Dialup the slow but yet annoying connection speed some of us had to experience and some of us still do

Dialup is when a modem is used to connect to the wall socket via a cable using a 66-45 cable to connect to the internet.

You require an internal modem for this connection or an external modem, most PCs still come with internal modems and some businesss still use dialup connections for when users go home and use VPN to connect to the companys servers.

What is fibre optic?

This has also been known as the speed of light, up to the gigabytes. This fibre optic cable has a bundle of glass threads, which have the ability of sending messages modulated onto light wave.

Fibre optic cables have a much greater bandwidth than metal cables. They have less interference, are much thinner and lighter than metal wires. The data is transmitted digitally not analogically.

Fibre optic is very expensive to install as well as being fragile.

What is ISDN?

Meaning integrated services digital network, a standard to send video, voice and data over a digital telephone line. IDSN connection speeds are from 64Kbps

There are two types of ISDN are basic rate interface and primary rate interface.

Basic Rate: Has two B channels consisting of 6Kbps and one D channel for transmitting

Primary Rate: Has 23 B channels and a single D channel.

What is ADSL?

Meaning asymmetric digital subscriber line, this is the most common type of internet world wide in todays society. This allows more data to be sent across existing copper telephone lines.

ADSL requires a specific modem as now has the capability of wireless as well as Ethernet.

ADSL connection is from 1.5Mbps to 9 Mbps when receiving data. When sending data it can connection up to 16Kpbs to 640kbs

Changing Channel - The Growing Popularity Of Broadband Television

What do you like watching on television? Whether you prefer talent shows, reality TV, movies or sports, you can find a channel for everything nowadays.

Although the age-old concept of watching the TV as a family may have changed over the years, many of us remain glued to our sets as we catch up on soap operas and award-winning documentaries.

And now more of us are making use of our broadband connections in order to watch television. With the rise of video-sharing websites such as YouTube and the introduction of applications that will allow you to watch programs from a certain channel, we now have a greater degree of choice in both what we watch and when we watch it.

Internet television has seen huge advances and growing popularity since it was launched, and now more television stations around the world are making use of the trend, combined with the growing popularity of cheap broadband in order to capture viewers.

And with more of us making use of the internet in our everyday lives, we have been given the chance to escape the sofa and watch programmes we've missed without the use of expensive set-top boxes.

With a wide range of subjects available for viewing, from sporting events to political debates, it has never been easier to access up-to-date information and programmes at times that suit us, all from the comfort of our laptops.

And as technology becomes more advanced, both online and offline, internet television continues to develop, with some services offering features such as user interaction whilst viewing programs - without covering up the screen with annoying pop-ups and disrupting the viewing experience

So now, as well as viewing high-quality videos on a full screen, viewers can now not only search for biographies on actors, information on places seen on screen, but also jump to certain parts of scenes by using keywords.

In order to make the most of such services, it is advisable to make sure your connection is up-to-speed through use of a broadband speed test.

As technology develops, more of us are making use of affordable computers and laptops, cheaper broadband and a wide range of online services. And as more of us turn to watching television online, could this perhaps be a turning point for 'couch potatoes'?

Looking for better broadband? Perform a broadband speed test and compare cheap broadband providers to find a deal that suits you.

3G EV-DO or How the Internet Got Its Wings!

The Internet, as most people know it, is history.

It just seems like yesterday the Internet was just one big mass of wires and cables; a glorified file sharing warehouse with more than a few too many lines sticking out. One enormous LAN party that just got out of hand, causing a ruckus and spilling out down the block and around the world; creating too many millionaires for no good reason and causing too many sleepless nights surfing the neon pink.

The Internet quietly crept into every facet of our lives... no subject or topic was left unexplored in this binary medium. Suddenly, there it was, the authority on everything. Our lives encyclopedia-ed to death by bits and bites.

But the Internet has always been perceived as a connected medium; tied together by cables, servers and networks. Until now that is, because now everything has changed. And it's about time, the Internet has been tied to the ground for far too long, it's time for liberation. Independence Day. Bring it on!

The Internet is going Wireless -- for real this time.

There were a few false starts; you can Bluetooth yourself silly, but you won't get much further than 30 feet or so. The BlackBerry is great but a little limiting. And Wi-Fi services have been around for a long while but those were not really convenient, if you have to find something; it's not convenient. Finding a 'hot spot' is the space age equivalent of finding a 'needle in a haystack'; takes way too much time.

What changes things, what has finally given the Internet its liberation?

Verizon Wireless 3G EV-DO (evolution-data optimized) and other companies offering similar services around the world. This new technology will change how we view and use the world wide web. Verizon Wireless began commercial operations in Oct. of 2003 and is now expanding to over 125 million US consumers by the end of 2005.

With download speeds of 400 to 700 kbps and bursts up to 2 Mbps, 3G has really given us wireless Internet this time. It has or will turn the Internet into a truly wireless system that's devoid of any cables or lines and really make it omnipotent. It will be everywhere. No space within our biosphere will be without the Internet very soon.

For now Verizon Wireless or 3G is mainly located in the USA but this will quickly change as other 3G companies and systems start up to fulfill the demand. Wi-Fi may play a role too but will it go the way of the 'Beta'?

However, this wireless universe could not be possible without one other key element. The one element that also helped give the Internet its wings. The answer might or might not surprise you. What really gave the Internet its groove? Can you guess? Give up?

Finally, we come to the last element of this brand new liberated Internet -- the little notebook computer. Don't underestimate the power of this great little revolutionary device, it is doing for the Internet what the cell phone did for the phone industry -- making it wireless, portable, and accessible anywhere.

It could even be argued that it was the little notebook computer that gave the Internet its freedom. Finally cutting the cable and freeing the web, once and for all.

Once we had a portable computer that we could tuck under our arm and take anywhere; we naturally wanted to take the Internet along with it. After all, a computer without the Internet is like having Mickey Mouse without Disneyland -- a real downer -- any kid can tell you that!

Once the notebook or laptop computer gained in popularity, the demand for a wireless Internet grew right along with it. The portability factor being a strong selling point for both the notebook and the Internet.

Likewise, in order to take full advantage of each of them; for business operations, for personal communications, for emailing, for web surfing... a wireless portable Internet was the obvious next step. They compliment each other perfectly and one is not completely whole without the other.

Technology has created this unholy trinity (the Internet, wireless connections and the notebook computer) to fulfill our need for a portable communication system that we can take and access anywhere. Until now, the Internet was limited, tied to cables and wires...it never really got off the ground!

But watch out; the cables are cut, the training wheels are off, the bells are starting to ring real fast and this child has found its groove.

Every time a notebook opens, the Internet gets its wings!
