Bandwidth

Definition: Bandwidth has different definitions in many applications. In Radio, bandwidth is called the set of frequencies occupied by modulated waves. Related to computer website designing, bandwidth is the amount of data transferred from one web site to another web site. Thus, bandwidth is called data rate or range of a communication system. Band width definition varies in computer systems both in Analogue and Digital systems. More bandwidth is required in Wireless Internet.

Bandwidth with respect to Web Hosting:

With respect to web hosting, bandwidth is the amount of data which is transferred to a website or web server, and it is measured in terms of bytes, kilobytes and megabytes, etc. where it is necessary to measure when selecting between multiple types of web hosting such as ecommerce web hosting, managed, dedicated servers and many other web hosting services.
In web hosting, bandwidth is measured as a monthly data transfer. Many hosting companies provide bandwidth for individuals and organizations and levy a charge based on bandwidth used. A website administrator or developer needs to estimate how much bandwidth is required for his website to determine the cost.

Bandwidth by General and Advanced Web Hosting:

The type of  Web Hosting is selected based on bandwidth and web space required. For small organizations,  general web hosting is preferred -  Unix Linux web hosting, Windows Hosting, Ecommerce Hosting, Budget Hosting, Reseller Hosting and Adult Hosting. For large organizations which have huge databases and complex systems, Advanced Web Hosting is used - Managed Hosting, Dedicated Server, Colocation Hosting and Virtual and Private Servers etc.

Bandwidth with Respect to Analogue System:

In analogue signals, bandwidth is measured in terms of Hertz (cycles). The bandwidth is measured as a difference between two frequencies. As the bandwidth of the system increases, the system can transmit data more speedily and quickly in order to handle instructions.
In analogue systems, bandwidth may mean:

• The bandwidth is called the output of light source. So the distance to which the light can reach is called the bandwidth of light.
• It is called the width of frequencies when transported over some media such as fiber optic cable, and it is known as a pathway within a network.
• Bandwidth is also known as the maximum modulation frequency in a modulator.
• It may also be known as the measurement of frequencies in which some devices can operate themselves.
• It is called the data rate to transfer information form source to destination in a communication system.

Bandwidth in Digital Systems:

With respect to digital communication, bandwidth means that the rate at which symbols can be transmitted from source to destination in online business using ecommerce web hosting - more precisely the rate at which the bit can be transmitted form one system to other. Symbols which are transmitted may consist of more then one bit or multiple bits. Digital transmission is normally done through a modem which is capable of modulation and demodulation of data. Modems transform the analogue data into digital format. A modem can transmit 56 kbit /s over a telephone line while using a bandwidth of 4 kHz. Broadband systems have greater bandwidth, and can carry larger amounts of data via the cable used in broadband systems .
