High-speed dial-up internet offers faster download speeds than typical dial-up, but cannot speed up all processes. Accelerator servers use compression, caching, and pop-up blockers to improve speed for dial-up users, but it still has limitations compared to broadband.
High-speed dial-up Internet service is a type of Internet service that offers faster download speeds than typical dial-up service for some web features. A high-speed connection often costs more than a regular dial-up connection, but still less than many broadband connections. Advertisers of such a service claim that in some cases it can be up to five times faster than regular dial-up service. Actually, while it can speed up some processes, it can’t speed up all processes.
High-speed dial-up service works by using a variety of different methods to make your Internet connection faster. It should be noted that bandwidth on phone lines is determined by the capacity of the phone line. Thus, the connection speed does not actually improve. Instead, the Internet Service Provider (ISP) uses shortcuts for establishing communication, compression, filtering and caching in order to make the connection faster for the user. While web pages usually load faster, the connection itself is the same as a regular dial-up connection.
The key to high-speed remote access service is in accelerator servers. These servers, used by your ISP, do several things to improve speed for dial-up users. The most common strategy employed is that of compression. Compression reduces the size of images and other types of data. In most cases, the resulting visual degradation is difficult, if not impossible, to notice, however it can make a big difference in file size, thus allowing items to load faster.
Another strategy is called caching, which means temporarily storing frequently used web page files on your computer’s hard drive. Most computers already do this to some extent. With high-speed dial-up service, however, a server will take note of the most visited sites and prioritize caching for those sites, thus reducing the time it takes to send and receive information from the main server.
The other common strategy is to use a pop-up blocker. While many ISPs and Internet browsers already have this feature, it’s also a staple of high-speed dial-up service. Pop-up ads take up a large amount of bandwidth, especially those that use Java or similar programs. Therefore, they can significantly increase the time it takes to load the desired page. Pop-up blockers help prevent this process in the first place.
Prospective subscribers should keep in mind that there are some things the high-speed connection can’t do. It cannot substantially increase speed when downloading files, such as music or large attachments. It also can’t speed up the download of many types of email or increase the speed of video streaming. Therefore, even with its advantages, there will still be some shortcomings compared to broadband.
