Since dial-up Internet connection is very slow and you can not literally do your work comfortably with it, a dial-up accelerator almost became a complement to dial-up internet. These accelerators increase the speed of a dial-up connection considerably. But have you ever thought about how this accelerator works?
Dial-up accelerator uses the technique called Prefetching majorly. When you visit a web site and download a page, these pages are recorded and stored in the form of files. While you work on the page, the dial-up accelerator looks at the page and finds all the links it has to any pages. When the accelerator finds any links to the page, it downloads each of these links. These links are stored in your hard disk. When you try to visit the page you have visited already or the page to which links are stored, they are downloaded instantly. This is because, your dial-up doesn't need to download the webpage again and it just retrieves the page stored in your hard disk. This decreases the time of download very much and it also saves the energy.
Dial-up accelerator caches frequently visited and recently visited documents which means that it stores the pages and images and when you try to open the page at a later time, it just needs to open already stored web page and this will be done at a faster rate.
A dial-up accelerator compresses the documents to a smaller size. For this, the accelerator reduces the quality of images and font and sends only data which is changed since it was last viewed.
Some dial-up accelerators filters the ads and stop them from displaying. This saves a lot of time as the ads on a web page take more time to load and slows the whole process of opening a web page. They also block unwanted pop-ups from appearing, thus decreasing the time taken to open a web page.
Some accelerators stop the images from displaying as they also take a long time to load and appear. But if you want to see the images, you can change the settings and can view them. Thus you can block the unwanted images and ads and view only certain images and ads you want to see.
By following the techniques said above, a dial up accelerator increases the internet speed considerably.
