Most computers are not directly connected to the Internet.They connected to the smaller networks that connect through GATEWAYS to the internet BACK BONE. That is why the internet is sometimes called “NETWORK OF NETWORKS”

The internet Architecture Board(IAB)-which is concerned with the technical and policy-making issues.

COMMUNICATING ON THE INTERNET  ELECTRONIC

MAIL or e-mail is an efficient and inexpensive way to send and receive messages and documents around the world within minutes, via Internet. Anyone with an e-mail account can send messages to other users of the Internet and to many network connected to the Internet through gateways. Most email programs also permit users to attach data files and program files to messages.

E-mail is not a live connection between the sender of the message and the receiver. There is always some delay between the time the messages is sent and the time it arrives. This delay is there due to the store-and- forward system on which e-mail works. When a message is sent, the computer passes it to a POST OFFICE SERVER, which identifies the destination address and passes it through the internet to MAIL SERVER , where the message is stored until the recipient opens his mail . E-mail programs generally combine the following features: A text editor for writing an editing messages. An address book for storing names and E-mail addresses. Ability to transfer out bound messages to the post office server. Ability to receive inbound messages from the E-mail server. A message manager that organizes and stores sent and received messages.
