Bandwidth refers to the amount of digital information that is transferred from one point to another. It is the transmission capacity of an electronic line such as a communications network, computer bus or computer channel. It is expressed in bits per second, bytes per second or in Hertz (cycles per second).
Whenever someone visits your Web site, the files which compose your site (graphics and HTML) are downloaded by their Web browser. Imagine that the home page (index) of your Web presence contains two images of 5,000 bytes each (5k) and another 5,000 bytes of text. If your web hosting firm allows 1 GB (gigabyte) of data transfer per month, your main page index could be viewed over 66,000 times for the allowed 1,000 megabytes of data transfer bandwidth.
Our statistics show that less than 5% of all Web sites will generate greater bandwidth usage than 1 GB monthly. However, normally, the cost of transmitting data is much higher than that of receiving. Thus most organizations tend to have more incoming bandwidth (128 kilobytes) than outgoing (64 kilobytes)
Bandwidth is a somewhat confusing and a commonly misunderstood term because in the past it has been used in many different ways. Bandwidth primarily means a measure of data transfer speeds or as a measure of space available for data to occupy. What does that have to do with you? When it comes to the Internet, bandwidth relates to the amount of information that is moved in a specific amount of time. The amount of bandwidth that is transmitted affects many aspects of online communication and conferencing such as web telephony, file sharing, videoconferencing, and webcams. We hear of the word broadband well, broadband comes from the words “broad bandwidth” and is used to describe a high-speed connection to the Internet. A broadband connection lets you instantly connect to the Internet or your corporate network at speeds many times faster than a dial-up connection.
In today's world when high connections are not only important but are gradually becoming a necessity what effect does it have on the realm of Internet technology? As the use of high speed access increases so will the need for Internet Bandwidth, because of this cables that are used to carry Internet packets are growing larger and faster as companies and individuals strive to keep up with the increasing rate of Internet use and the flow of information. Video and audio files alone use a tremendous amount of bandwidth and the problem with slow or lost data is the culprit when it comes to poor video and audio quality, therefore not giving you the results that you desire.
It is not uncommon for an Internet Service Provider (ISP) to place bandwidth restrictions on a Web page that is hosted by them. The ISP allows users to download a certain number of bits per month and when that bandwidth limit is exceeded the ISP charges the owner of that site for the additional bits that were absorbed. This is why it is not uncommon to hear of camgirls who have very popular sites being charged for additional bandwidth that was used by their viewers. The cost of the extra bandwidth doesn't make camming a cheap hobby for those girls and eventually they are forced to charge, implement affiliate links to draw in supplemental income, or eventually give up their webcam hobby.
If you have been using the Internet for a significant amount of time you have probably heard the rumor that the Internet is going to eventually run out of bandwidth. Is there any truth to this? In order to dispels this rumor you must understand a bit about the infrastructure behind the Internet. The Internet has been built on a scalable system, allowing more capacity to be added when needed. A problem that is not so easy to correct is that the routers which is a device that connects a number of local-area networks (LANs) are being bottlenecked by bandwidth. They are still operational in the megabit range, but it's not uncommon for them to be bogged by the increasing demand to reach gigabits. As the face of the Web continues to change the need hard-pressed need for more bandwidth will be ever-increasing to meet the needs of today's world. Bandwidth will be used to encompass high-tech videoconferencing, telephony, virtual reality, web cams and more.
Together broadband and bandwidth will not only change the way businesses operate but it will also change the way the average online user lives.
