Define and explain following Internet
protocols
1: HTTP (HYPER TEXT TRANSFER
PROTOCOL):
HTTP is protocol which allows the fetching of
resources. HTTP is a TCP/IP based
communication protocol that is used to
deliver data (html files, images files, queries
result).
2. SMTP (SIMPLE MAIL TRANSFER
PROTOCOL):
SMTP is utilized to send and get messages. It
is here and there matched with IMAP or POP3
(for instance, by means of a client level
application), which handles the recovery of
messages, while SMTP fundamentally sends
messages to the worker for sending. SMTP
can send and get mail, however lining
approaching messages is awful, so an overall
assignment to different conventions.
Proprietorship frameworks, like Gmail, have
their own mail move conventions when
utilizing their own workers, yet they actually
utilize obsolete SMTP for email. How it
works? SMTP is an uneven convention, with
numerous customers communicating with the
worker utilizing a model that got well known
during the 1980s, which is currently generally
out of the email convention. SMTP runs on
TCP/IP and tunes in on port 25.
3. POP3 (POST OFFICE PROTOCOL3):
Post Office Protocol version 3 (POP3) is a mail
protocol used to retrieve mail from a remote
server to a local email client. POP3 copies the
mail from the remote server into the local
mail client. Optionally, mail is deleted after it
is downloaded from the server. This saves
space on the server.
4. IMAP (INTERNET MESSAGE ACCESS
PROTOCOL): IMAP is a standard email
protocol that stores email messages on a mail
server and it also allows the end user or
application to view and manipulate the
messages as though they were stored locally
on the end user's computing device(s)>
5. FTP (FILE TRANFER PROTOCOL):
FTP servers are the solutions used to facilitate
file transfers across the internet. If you send
files using FTP, files are either uploaded or
downloaded to the FTP server. When you're
uploading files, the files are transferred from
a personal computer to the server.
6. TELNET:
Telnet is a protocol that allows you to connect
to remote computers (called hosts) over a
TCP/IP network (such as the internet).
Using telnet client software on your computer,
you can make a connection to a telnet server
(that is, the remote host).
7. SSL (SECURE SOCKETS LAYER)/ TLS
(TRANSPORT LAYER SECURITY):
The Secure Sockets Layer, or SSL, unique
name of the convention was created by
Netscape during the 1990s, when the
organization made the most mainstream
internet browser. SSL 1.0 has never been
delivered to the general population and there
are not kidding imperfections in SSL 2.0. SSL
3.0 was delivered in 1996, was totally
reexamined and set to the following level.
8: PING:
The Ping tool is used to test whether a
particular host is reachable across an IP
network or not. The Ping tool measures and
records the round-trip time of the packet and
any losses along the way. A Ping measures
the time it takes for packets to be sent from
the local host to a destination computer and
back.
9:TRACERT
The tracert is a Command that is used to
show several details about the path that a
packet takes from the computer or a device
you are on to whatever destination you
specify.
