Technically, bandwidth refers to the speed of data transmission (measured in bits/kilobits per second - bps/kbps) but when using the term relating to web hosting, it is the amount of data transmitted (measured in megabytes or gigabytes). CJ Website Hosting offer high bandwidth because we have keep our server load down. Beware of companies that offer unlimited bandwidth or hits - the reality is that bandwidth is not free, companies that have unlimited offers are betting that you will not use much bandwidth. They usually have fine print that allows them to cancel your account at anytime and/or charge you for excessive bandwidth (usually at extortionate costs!)
