Bandwidth optimization is one of many concerns webmasters deal with when hosting web content. Since most web hosts charge by bandwidth used or have an account limit on bandwidth, a prudent webmaster will squeeze and compress their files as much as possible without affecting the content's integrity. Lately, most web hosts are offering unlimited bandwidth. Reductions in bandwidth usage are measured in negabytes, a unit akin to other "negative" units such as negawatts, negavolts, negajoules, negameters, and negagrams. Even the simplest bandwidth optimization techniques can reduce bandwidth costs significantly. Owners of extremely high-volume web services are especially diligent, and have been known to employ extreme techniques to save a few bytes per page. For example, many staple pages are highly optimized - with whitespace and line breaks removed, unneeded quotes removed around HTML attributes, and images compressed to the limit while maintaining clarity.
