Status OK - The file request was successful. For example, a page or image was found and loaded properly in a browser. Some poorly developed content management systems return 200 status codes even when a file does not exist. The proper response for file not found is a 404.

Moved Permanently - The file has been moved permanently to a new location. This is the preferred method of redirecting for most pages or websites. If you are going to move an entire site to a new location you may want to test moving a file or folder first, and then if that ranks well you may want to proceed with moving the entire site. Depending on your site authority and crawl frequency it may take anywhere from a few days to a month or so for the 301 redirect to be picked up. See also: W3C HTTP 1.1 Status Code Definitions On Apache servers you can redirect URLs in a .htaccess file or via in the headers of some dynamic pages. Most web hosts run on Apache. On IIS servers you can redirect using ASP or ASP.net, or from within the internet manager.

Found - The file has been found, but is temporarily located at another URI. Generally, as it relates to SEO, it is typically best to avoid using 302 redirects. Some search engines struggle with redirect handling. Due to poor processing of 302 redirects some search engines have allowed competing businesses to hijack the listings of competitors.

Third generation (3G) wireless networks will offer faster data transfer rates than current networks. The first generation of wireless (1G) was analog cellular. The second generation (2G) is digital cellular, featuring integrated voice and data communications. So-called 2.5G networks offer incremental speed increases. 3G networks will offer dramatically improved data transfer rates, enabling new wireless applications such as streaming media.

Not Found - The server was unable to locate the URL. Some content management systems send 404 status codes when documents do exist. Ensure files that exist do give a 200 status code and requests for files that do not exist give a 404 status code. You may also want to check with your host to see if you can set up a custom 404 error page which makes it easy for site visitors to view your most popular and / or most relevant navigational options report navigational problems within your site Search engines request a robots.txt file to see what portions of your site they are allowed to crawl. Many browsers request a favicon.ico file when loading your site. While neither of these files are necessary, creating them will help keep your log files clean so you can focus on whatever other errors your site might have.

A standard compression algorithm, used in digital communications systems of the European digital hierarchy, to optimize, i.e., modify, the dynamic range of an analog signal for digitizing. Note: The wide dynamic range of speech does not lend itself well to efficient linear digital encoding. A-law encoding effectively reduces the dynamic range of the signal, thereby increasing the coding efficiency and resulting in a signal-to-distortion ratio that is superior to that obtained by linear encoding for a given number of bits.
