Do you remember using the Internet back when you had to dial in using a modem? First you dialled, then you listened to screeching noises, and then, if you were lucky, you were connected at a snail’s pace. Worse, it was impractical to leave the connection on all the time, as it would drop out at random and have to redial every time you restarted the machine.

If you’re unlucky enough to still be using dial-up Internet access, I feel for you. Why not come and join us in the age of broadband? Broadband is revolutionary, always-on, much faster Internet access, letting you download much larger files and use the Internet whenever you want, with no waiting. If you’ve been put off broadband because you think it’s expensive, think again – the remaining dial-up ISPs like AOL are charging just as much for dial-up access as you would pay for broadband.

The biggest problem many new broadband users have, though, is confusion over what kind of broadband they should get. With that in mind, here’s a basic rundown.

DSL broadband is the most common kind. It is broadband that works over a normal phone line, as long as the telephone exchange is DSL-enabled, and can be bought either from your existing phone provider or from a dedicated ISP.

Another common kind of broadband is cable. Instead of buying it from your phone supplier, you get it from your cable TV supplier, often as part of a package deal. If you already have cable, this can be a better option for you, as it is often cheaper and faster than DSL.

Finally, if you’re stuck out in the middle of nowhere without a DSL-enabled line and with no local cable company, you should consider satellite broadband. Satellite broadband is a clever way of accessing the Internet using a normal dial-up connection to send things but a satellite to download them. While it’s not cheap and suffers in the speed stakes, it is much better than sticking with dial-up.

Do you have any website on your own? Or have you been involved in hosting a website for your company or some of your friends? Then you should have heard about the term Bandwidth and Data transfer. Often there is confusion in understanding both these terms.

Bandwidth is the capacity of the network or the server that hosts the website, to send data at a moment. It is the amount of data sent per second from the server. This count more because, if there are many websites in the server and a million hits for the sites the server should be capable of sending that much of data at that moment. If the web server that you host your website has high bandwidth then the users visiting your site would see the pages quickly.

If you refer to the bandwidth there are two numbers separated by “/”. The first number indicates the bandwidth that is allowed to send data and the second number indicates the bandwidth allowed to receive data. In most of the cases the bandwidth to send data is less than the bandwidth to receive data.

Data transfer is the amount of data that is sent by the server over a period of time. For example the monthly data transfer allowed for a particular site might be 1GB. This means that the website account is allowed to transfer data from their website for only 1GB per month.

Consider that you have a page in your website that is of size 100kb. If this page is visited 100 times per month, then the data transfer added to your account would be 10 MB due to this page alone. Hence to minimize the data transfer it is always better to minimize the file size of the web page. This can be done in many ways.

You should know that a web page contains not only text but also media content such as images, sounds, videos, and downloadable files. When you create your web page you should keep in mind that you optimizing all these files so that the page loads quickly and the data transfer is kept at the minimum. That is why most of the photos related sites have thumbnail pictures so that they can reduce the data transfer due to the main page and the user is allowed to download the actual image only if they are interested in seeing that image.

While hosting a website with a service provider most of us tend to see only the features that are available for your hosting and the web space that is provided for your plan. The cost to the web hosting company due to these are very less when compared to the cost due to data transfer.

If you know that you website is going to attract a lot of visitors to it, then you should go for an account or plan that has more data transfer per month. This would save you a lot of money. So the next time you purchase a web hosting plan keep an eye on the Data Transfer allowed for your plan.

The term bandwidth is very common these days, especially because its technology affects almost all aspects of our lives. You use bandwidth when you connect to the internet, when you use the telephone, when you watch television, and in many other activities. But what exactly is bandwidth? Read on to find out and see how it can change your life.
Bandwidth defined
The term ‘bandwidth’ refers to the amount of data or information that can be transmitted over a network in a given time, or, in much simpler terms, is a measure of how much ‘stuff’ is sent through any connection. Information sent can take many forms depending on the channel.
How bandwidth affects you
Bandwidth in internet terms is usually expressed in either bits per second (bps), kilobits per second (kbps), or megabits per second (mbps). The higher the bandwidth of your connection, the faster you can upload and download data from the internet. Dial-up connections are low speed at only about 50+ kbps, while better cable connections go from 500 kbps and up. Whether you need a connection that has bigger bandwidth depends on your purposes for using the internet. If you only use the net for text-based research purposes, you don’t need much bandwidth. A whole page of English text is only about 16,000 bits, so if your modem can move about 57,000 bits per second, you are more than covered. You may need higher bandwidth if you upload or download full-motion and full-screen video, which, depending on compression, requires roughly 10,000,000 bits-per-second. It is wise to subscribe to a high-bandwidth connection if you use the internet for pictures, graphics, music and videos.
The telephones use bandwidth, too – in fact, a bandwidth of about 3,000 ‘cycles per second’ (cps) is required for voice transmission. The bandwidth required for television broadcasting is even higher at about 6 million cps, and satellite system prevent interference by spreading television signals using bandwidth of as little as 17.5 MHz to a as much as 72 MHz.
