What are different types of protocols?

Types of Protocols

• Transmission Control Protocol (TCP)
• Internet Protocol (IP)
• User Datagram Protocol (UDP)
• Post office Protocol (POP)
• Simple mail transport Protocol (SMTP)
• File Transfer Protocol (FTP)
• Hyper Text Transfer Protocol (HTTP)
• Hyper Text Transfer Protocol Secure (HTTPS)

Why are there so many different types of protocols?

Today, majority of the systems cannot function without being able to communicate with their surroundings. The surroundings might be made of other systems or we humans. So this need, to enable systems to communicate with each other including humans, is central to the development of all the communication protocols.

How many types of network protocols are there?

There are three main types of network protocols, including network management protocols, network communication protocols and network security protocols.

How do protocols work?

A protocol is a standard set of rules that allow electronic devices to communicate with each other. These rules include what type of data may be transmitted, what commands are used to send and receive data, and how data transfers are confirmed. If two people share the same language, they can communicate effectively.

What are the main functions of protocols?

Protocols provide us with a medium and set of rules to establish communication between different devices for the exchange of data and other services. Protocols are needed in every field like society, science & technology, Data Communication, media, etc.

How does the TCP protocol work?

TCP organizes data so that it can be transmitted between a server and a client. It guarantees the integrity of the data being communicated over a network. Before it transmits data, TCP establishes a connection between a source and its destination, which it ensures remains live until communication begins.

Which protocol is used to send and receive data over HTTP?

HTTP Protocol The HTTP protocol is based on TCP/IP or UDP /IP protocol. Before any data is sent to the receiver, a communication channel should be opened between the sender and the receiver. This is done using TCP/IP alone without any application layer, as shown in the diagram below.

What is SMTP and how does it work?

SMTP is what is used by Email servers all over the globe to communicate with each other, so that the assignment you submitted at 11:59 pm reaches your professor’s inbox within the deadline. How do their implementations differ? All the three are Application Layer Protocols, using TCP as the underlying Transport layer protocol.

What are the TCP/IP protocols and ports?

Common TCP/IP Protocols and Ports Protocol TCP/UDP Port Number Description File Transfer Protocol (FTP) (RFC 959) TCP 20/21 FTP is one of the most commonly used file transfer protocols on the Internet and within private networks.

What is the difference between a stateless protocol and FTP?

A Stateless protocol implies that the HTTP Web Server does not maintains which request had originated from which user. Hence, to give a customized service to the user, HTTP uses Cookies. FTP is Out-of-band, as it uses a separate channel to send data (Data connection), as to send control information (Control connection).
