Management Information Systems

Notes the Internet. This is a mechanism to broadcast news, called articles, from your local host to
the world. The news servers are not common in India; unfortunately, to read news you
may need to set up a server in your local host, and that takes quite a lot of memory (you
will have to reserve about half a Gigabyte for it). If you do not have full Internet connectivity,
you can subscribe to a mailing list. What you have to do is to send your name to some
server, and every day you will receive an e-mail containing news concerning the topic
you have subscribed to. There are news groups and mailing list about anything you can
imagine, from computers to research, sports, politics, etc.
5. WWW: The official description describes the World-Wide Web as a “wide-area *hypermedia*
information retrieval initiative aiming to give universal access to a large universe of
documents”. The operation of the Web relies on hypertext as its means of interacting with
users. Hypertext is basically the same as regular text - it can be stored, read, searched, or
edited - with an important exception: hypertext contains connections within the text to
other documents.

Example: By clicking here you can get to the next document, while clicking in this place
will take you back to the Internet page.
