Internet, Extranet, Intranet and WWW

• The Internet is a network of networks that is
  worldwide. That is, it is an INTERnational
  NETwork
• Use the same protocol for communications. It is
  called TCP/IP (Telecommunication
  Protocol/Internet Protocol).
• A communications facility that allows users'
  computers, called client computers, to send
  e-mail messages to other users' computers
  anywhere in the world. It allows client computers
  to access information (text, pictures, sounds,
  etc.) stored on service computers, called
  servers, anywhere in the world.
• The most used Internet facility is e-mail which
  not only enables people to send and receive
  personal and business messages, but also to take
  part in electronic discussions using newsgroups
  and lists.

10
Intranet

• Used by many companies and organizations to
  deliver private corporate information to internal
  users
• Uses Internet applications - primarily World Wide
  Web and E-mail, but also other applications such
  as FTP (File Transfer Protocol)
• work the same way they do on the World Wide Web
• You do need "Firewalls" that allow employees to
  venture out onto the Net, but prevent
  unauthorized users from coming in

11
Extranet

• An Extranet is an extension of a company's
  Intranet out onto the Internet. It allows the
  sharing of a company's data and/or operations
  with partners, customers, suppliers, and vendors.
  Such facilities receive very careful attention to
  security, and they are becoming an increasingly
  important means of delivering services and
  communicating efficiently.

Extranet
13
Important Concepts (Benjamin 1998)

• The Extranet is a derivative of both the Intranet
  and the Internet
• Its purpose is to allow both internal (mobile
  workers) and external (customers) populations
  access to the computer based information.
• Security is of utmost concern, as information is
  leaving the confines of the firm and being
  floated through the hands of those outside of the
  firm

World Wide Web

• WWW or the Web is the World Wide Web. It consists
  of a network of computers which provide Web pages
  to Internet users. These pages consist of
  hypertext which includes text (and pictures) to
  provide information along with links to other Web
  pages. Users access these pages using a browser
  which uses the addresses of the links to connect
  to and download the pages.
• Sometimes it is considered to be synonymous with
  the Internet when it is actually just a part of
  it.

15
Discussion Group

• As part of this discussion group, you will be
  placed on a distribution list (e.g., the
  art-glass_at_rivendell.com ). When you (or anyone
  for that matter) sends an E-mail to the group,
  everyone on the distribution list sees your note
  and is able to respond to your questions or learn
  from answers that you supply.

16
Newsgroup

• If subscribing to a mailing list is like joining
  a club, using newsgroups is like perusing a
  public bulletin board. If you want to ask advice
  about your computer, your love life, or your next
  vacation in Italy, without having to sign up for
  a mailing list or make small talk in a chat
  session, the best place to turn is to Usenet
  newsgroups. Usenet is a worldwide network of
  computers set up to transmit messages to
  newsgroups. There is no official Usenet governing
  body or organization--the servers on the network
  are administered by volunteers.

17

• Unlike mailing lists and chats, newsgroups allow
  readers to choose which topics they want to read.
  They don't clutter your mailbox, and they are
  neatly organized by topic. You post your message,
  other people read it and reply, and their
  messages get added below yours. Alternatively,
  people start new topics of their own a topic and
  its related responses are called a thread.

ICQ (I seek you)

• ICQ 2000b is the latest release of ICQ ("I seek
  you"), the popular instant-messaging program that
  lets you communicate with friends and colleagues
  in real time. To seek out a friend on the ICQ
  network, simply enter his or her ICQ number,
  name, nickname, or email address. Once your
  contact list is set up, you'll be notified when
  your friends are online so that you can chat
  send instant messages, files, and URLs play
  games or just hang out. (Download.com
