One of the most popular applications on the Internet today is electronic mail (email).All communication via TELNET is carried out through a virtual device called Network Virtual Terminal (NVT).TELNET (TErminal NETwork) is an Internet protocol that allows computer users to access computers from great distances (remote login). Through a particular user interface, the user is able to browse within the Web using a distinct URL (Uniform Resource Locator).Every email message issued from within the domain is first sent to the domain's mail server, which then directs the message to its destination.The message stays in the destination domain's mail server until the recipient requests to see their incoming mail.The local part specifies a special file, called the user mailbox, where all the incoming mail is stored for retrieval by the user agent.It establishes two connections between the linked devices: one for data transfer and one for control information (commands and responses).A client software application (Web browser) resides on the user's computer and is responsible for accessing information on the Web, and displaying it on the user's device.The domain name illustrates the computer which implements the specific SMTP server.

One of the most popular applications on the Internet today is
electronic mail (email). Messages are transferred among Internet
users through the support of a protocol called Simple Mail Transfer
Protocol (SMTP). Each domain’s local authority designates a
particular machine (mail server) within its domain to handle the
domain’s email activities. Every email message issued from within
the domain is first sent to the domain’s mail server, which then
directs the message to its destination. The message stays in the
destination domain’s mail server until the recipient requests to see
their incoming mail. SMTP uses a unique addressing system that
consists of two parts: a local part and a domain name separated by
an @ sign. The local part specifies a special file, called the user
mailbox, where all the incoming mail is stored for retrieval by the
user agent. The domain name illustrates the computer which
implements the specific SMTP server.
One standard protocol on the Internet for transferring files such as
documents, photographs, or other encoded data, is the File
Transfer Protocol (FTP). FTP is designed to deal with problems
such as different coding systems or diverse file formats. It
establishes two connections between the linked devices: one for
data transfer and one for control information (commands and
responses). The control connection has to be present throughout
the FTP session, while the data connection is present only when
there is data to be transferred.
TELNET (TErminal NETwork) is an Internet protocol that allows
computer users to access computers from great distances (remote
login). All communication via TELNET is carried out through a
virtual device called Network Virtual Terminal (NVT).

The World Wide Web (WWW), or the Web, is an application that
allows multimedia information to be shared across the Internet. It
is based on the concept of hypertext, which is a document
containing links (hyperlinks) to other documents. A hypertext
document is called a page, and a collection of closely related pages
forms a Web site. HTTP (Hypertext Transfer Protocol) is the
client-server program that is used so as to access and transfer
documents on the Web. A client software application (Web
browser) resides on the user’s computer and is responsible for
accessing information on the Web, and displaying it on the user’s
device. Through a particular user interface, the user is able to
browse within the Web using a distinct URL (Uniform Resource
Locator).
