  1. Various Types of Network Protocols

  2. Table of Contents • Network Protocol • TCP (Transmission Control Protocol) • IP (Internet Protocol) • UDP (User Datagram Protocol) • FTP (File Transfer Protocol) • POP (Post Office Protocol) • SMTP (Simple Mail Transfer Protocol) • HTTP (Hypertext Transfer Protocol) • HTTPS (Hypertext Transfer Protocol Secure) • Telnet • Gopher

  3. Network Protocol • A set of rules that has been established to specify the way in which data need to be transmitted between various devices in a network, is referred to as a network protocol. It lets devices that are connected with each other communicate, despite the differences that exist in their structure, internal processes or design. Network protocols play an important part in digital communications. • Various devices can interact with each other due to network protocols that ensure that predetermined rules exist in the software and hardware of these devices. In the absence of network protocols, neither a WAN (Wide Area Network) nor a LAN (Local Area Network) can function properly. • The various types of network protocols will be mentioned in the following slides.

  4. TCP (Transmission Control Protocol) • TCP is the abbreviation for Transmission Control Protocol. It is a very popular communication protocol that is meant for communicating over a network. Any message is divided by it into series of packets, which get sent from a source to the destination. At the destination these get reassembled.

  6. IP (Internet Protocol) • IP is the abbreviation for Internet Protocol. It is used as an addressing protocol. It is usually used along with the Transmission Control Protocol. TCP/IP is one of the most popular protocols for connecting networks. • The IP refers to a set of rules that exists for routing packets of data as well as for addressing them. This enables them to be transmitted across networks and ensures that they reach the correct destination. IP information is present in each data packet, which helps routers to send these data packets to their destination. • Every website on the Internet has an IP address. These websites are made accessible by web hosting companies through the service of web hosting. The most efficient web hosting services globally are usually referred to as the “Best Windows Shared Hosting”, the “Best Linux Dedicated Hosting” the “Top Cloud Hosting” etc.

  7. UDP (User Datagram Protocol) • UDP is the abbreviation for User Datagram Protocol, and it is a core component of the Internet Protocol suite. UDP enables applications to send messages, which are referred to as datagrams, to the hosts on an IP network. A User Datagram Protocol uses a connectionless communication model that has a minimum amount of protocol mechanisms. A UDP aids in creating such links between various applications, which are loss-tolerant and have low latency.

  8. FTP (File Transfer Protocol • FTP is the abbreviation for File Transfer Protocol, and it serves as a standard communication protocol for transferring files from a server to a client, over a network. It is built on the architecture of a client-server model.

  9. POP (Post Office Protocol) • POP is the abbreviation for Post Office Protocol. It is an application-layer Internet standard protocol. E-mail clients use it for retrieving e-mails from a mail server. POP3 i.e. POP version 3 is used most commonly.

  10. SMTP (Simple Mail Transfer Protocol) • SMTP is the abbreviation for Simple Mail Transfer Protocol. It is an Internet standard communication protocol for the transmission of electronic mail. SMTP is used by mail servers and by other message transfer agents for sending and receiving mail messages.

  11. HTTP (Hypertext Transfer Protocol) • HTTP is the abbreviation for Hypertext Transfer Protocol. It is used for transferring a hypertext between two systems or among multiple systems. It is an application layer protocol that is meant for collaborative, distributed information systems of hypermedia. HTTP acts as a request-response protocol in the client-server model.

  12. HTTPS (Hypertext Transfer Protocol Secure) • HTTPS is the abbreviation for Hypertext Transfer Protocol Secure, and it is an extension of HTTP (Hypertext Transfer Protocol). It is used extensively on the Internet, and is meant to ensure secure communication over a computer network. The communication protocol in it is encrypted with the aid of TLS (Transport Layer Security). Hence, it is also referred to as HTTP over TLS.

  13. Telnet • Telnet refers to an application protocol, which is used on the Internet or in LAN (Local Area Network). A bidirectional, interactive communication facility that is text-oriented is provided by it with the aid of a virtual terminal connection.

  14. Gopher • Gopher is a communication protocol that is meant for searching and distributing, as well as for retrieving documents in IP networks.
