Advantages of websites

The advantages of using the websites to find out the information are that the websites are mostly updated at least every day where as the books get updated very year or so. The other advantages of using the websites rather than paper base search is that the internet is available 24 hours a day where as the Libraries only open on certain times and also if you want to find out the latest news you have to wait till next day, and dread it from the news papers where as you can check the latest news on the internet as soon as it happened.

I prefer Internet to the paper based resources even if the Internet cost more money than books and newspapers. Internet can have images, writing, sounds, videos and all the other sort of attractive things where as the news papers and books can only have images and writing.

The paper base resources like books, which are linear media. The linear media is that user has to go through each page before the user can get to his destination.

The Internet is hyper media, and the user can go on the required page by clicking on the link. This is another advantage of using the Internet instead of books.

ADSL

Asymmetric Digital Subscriber Line (ADSL) is a form of DSL, a data communications technology that enables faster data transmission over copper telephone lines than a conventional modem can provide.

For conventional ADSL, downstream rates start at 256 kbit/s and typically reach 8 Mbit/s within 1.5 km (5000 ft) of the DSLAM equipped central office or remote terminal. Upstream rates start at 64 kbit/s and typically reach 256 kbit/s but can go as high as 1024 ...
