Standards Protocols in Networking & Data Sharing

I. HTTP    : Hypertext Transfer Protocol

It is an application protocol for distributed, collaborative, hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web. Hypertext is a multi-linear set of objects, building a network by using logical links between the nodes. HTTP is the protocol to exchange or transfer hypertext.

II. FTP      : File Transfer Protocol

It is a standard network protocol used to transfer files from one host to another host over a TCP-based network, such as the Internet. FTP is built on a client-server architecture and uses separate control and data connections between the client and the server. FTP users may authenticate themselves using a clear-text sign-in protocol, normally in the form of a username and password, but can connect anonymously if the server is configured to allow it. For secure transmission that hides (encrypts) the username and password, and encrypts the content,

III. IP         : Internet Protocol

It is the principal communications protocol used for relaying datagrams across an internet work using the Internet Protocol Suite. Responsible for routing packets across network boundaries and has the task of delivering datagrams from the source host to the destination host solely based on the addresses. It is the primary protocol that establishes the Internet.

IV. TCP    : Transmission Control Protocol

It is one of the core protocols of the Internet Protocol Suite. Complementing the Internet Protocol (IP), and therefore the entire suite is commonly referred to as TCP/IP. TCP provides reliable, ordered delivery of a stream of octets from a program on one computer to another program on another computer. TCP is the protocol used by major Internet applications such as the World Wide Web, email, remote administration and file transfer.

V. POP3   : Post Office Protocol (version 3)

It is an application-layer Internet standard protocol used by local e-mail clients to retrieve e-mail from a remote server over a TCP/IP connection. POP and IMAP (Internet Message Access Protocol) are the two most prevalent Internet standard protocols for e-mail retrieval. Most webmail service providers such as Hotmail, Gmail and Yahoo! Mail also provide IMAP and POP3 service.

VI. SMTP : Simple Mail Transfer Protocol

It is an Internet standard for e-mail transmission across IP networks. While electronic mail servers and other mail transfer agents use SMTP to send and receive mail messages, user-level client mail applications typically only use SMTP for sending messages to a mail server for relaying.

VII. DNS   : Domain Name System

It is a hierarchical distributed naming system for computers, services, or any resource connected to the Internet or a private network. A DNS resolves queries for these names into IP addresses for the purpose of locating computer services and devices worldwide. By providing a worldwide, distributed keyword-based redirection service, the Domain Name System is an essential component of the functionality of the Internet.

VIII. Telnet :

It is a network protocol used on the Internet or local area networks to provide a bidirectional interactive text-oriented communications facility using a virtual terminal connection. User data is interspersed in-band with Telnet control information in an 8-bit byte oriented data connection over the TCP.
