Ethernet
The most widely used technology for local area networks (LANs). Standard
ethernet runs at 10 Mb/s, 100 Mb/s or 1000 Mb/s. It balances speed, price,
ease of installation and availability.
ETRN
ETRN (Extended Turn) is an extension to the Simple Mail Transfer Protocol
(SMTP) that allows an SMTP server to send a request to another SMTP
server to send any email messages it has. Typically, SMTP is used with two
other protocols, Post Office Protocol 3 (POP3) or Internet Message Access
Protocol (IMAP), to request messages from a server; SMTP by itself cannot
request mail to be sent.
ETRN is designed for use by anyone who is traveling and wants to access
their email. ETRN can only be used with Internet service providers (ISPs)
that support ETRN.
Extended Simple Mail Transfer Protocol (ESMTP)
The Extended Simple Mail Transfer Protocol specifies extensions to the
original SMTP protocol for sending email that supports graphics, audio and
video files, and text in various national languages. ESMTP provides the
capability for a client email program to inquire of a server email program
about which capabilities it supports and then communicate accordingly.
File sharing
The public or private sharing of computer data or space in a network with
various levels of access privileges.
File Transfer Protocol (FTP)
A standard Internet protocol and a way to exchange files between computers
connected to the Internet. FTP is an application protocol that uses TCP/IP
protocols. FTP is commonly used to transfer Web page files from the
computer that was used to create the files to the computer that acts as the
server for these files. It is also used to download programs and other files to
your computer from other servers.
Using FTP, you can update—delete, rename, move and copy—files at a
server. You need to log on to an FTP server. However, publicly available files
are easily accessed using anonymous FTP.
