Types of Internet Protocols

By

Internet protocols are different types of Internet connections for different things on the World Wide Web. They help in the retrieval, transfer, exchange and downloading of files, or information on the Internet. Without these protocols, the Internet would not be, as we know it today because many browsers would not work without the permission of these protocols. There are different types of Internet protocols each serving a different purpose. These are

1. Electronic mail transfer protocol
This protocol allows for the use and availability of email, it is what the post office is to letters. It consists of three other protocols that make transfer and access of the emails; these are the simple mail transfer protocol (SMTP), the Internet message access protocol (IMAP) and the Post office protocol 3 (POP3). The IMAP and POP3 are the protocols that allow you to receive emails while the SMTP is used when sending emails hence the "transfer" part. These three protocols are embedded in most web browsers.

2. NNTP
This protocol is used as a server of Usenet forums that are dedicated to organizational forums that have different topics of discussion. These forums are broken down to topics, subjects or genres. This protocol offers a platform where they can be discussed and views exchanged.

3. File retrieval protocols
As the name suggest, this protocols allow you to retrieve information from the Internet to the computer or from the computer to the Internet. Though it is now redundant, you could use it to view the files if you knew the name of the file or properties about it.

4. FTP (File Transfer Protocol)
The file transfer protocol is a protocol that allows you to move one file from your computer to another on the Internet. You can also log on to a computer remotely and access the files in it with authority from the other computer. This protocol also allows downloading of applications from the Internet.

5. Telnet
This protocol allows you to access a remote computer. It works in such a way you are able to view files on the other computer as if you were there by telneting into a specific file or application in the remote computer and you are able to see what is on the computer. It is a darling with many hackers.

6. Gopher
Gopher allows you to know a few details about a file, application or a description of a file before you download it. These files could be on a remote computer and gopher allows you to view these files in a hierarchical manner and delivers them to you when you search them on the server.

7. HTTP
This protocol allows web servers to show and display all the aspects of a webpage. They form the first part of every web address such that all web pages or website. This protocol makes it easy for the file transfer protocol to do its work.
