Do you want to know what is protocol in a computer network? how many types of these are, what it means, What are its uses and what are its benefits, then you have come to the right place, after reading this article you will be able to understand the network protocol well.
There are many types of protocol and all of them have an important role in this process. This topic is quite complicated to say, but after reading this post, what do you call protocol? This will be understood as well as how the protocol works? It will also be fully known. If you are preparing for an IT exam, then questions related to protocol can be asked in it. So, let’s first know What is Protocol? Then let’s look at the rest of its aspects.
What is Protocol?
Protocol is a type of “set of rules” that are used in digital communication. The protocol itself determines how the data will be transmitted and received on the computer network. In computing, protocol is also called digital language. Without them, we cannot communicate with each other on the Internet, nor can we transfer data from one computer to another. Any file or mail we send to the Internet works according to this Internet protocol.
For example, we humans have also made many traffic rules for our organized traffic, by following which we also save our time and also maintain our safety. Similarly, some protocols are made for the systematic and safe transfer of data on the Internet network, which we also call network protocols. So overall a protocol is a set of rules and guidelines for data communication.
There are many types and their functions are also different. That is why they are defined by different names. Some of these specify communication standards and some provide complete information on the transmission process. Procedures performed by these protocols include data flow rate, data type, process nature, and device management.
How Many Types of Protocol are There?
There are several different 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 (f)
- Hypertext Transfer Protocol (HATP)
- Hypertext Transfer Protocol Secure (Hattaps)
- Telnet Protocol
- Gopher
Transmission Control Protocol (TCP)
Transmission Control Protocol (TCP) is a connection-oriented protocol that is responsible for establishing and maintaining a reliable connection between devices or systems. It does this by dividing the data into small packets, sending the packet to the destination and accepting the receipt of the packet. If a packet is lost or corrupted during transmission, TCP will resend them until they are successfully delivered.
TCP is a transport protocol, which means that it is responsible for managing the transmission of data between devices or systems. It works on the transport layer of the communication stack, and is commonly used in conjunction with the Internet Protocol (IP) to transmit data over the Internet or other networks.
Internet Protocol (IP)
Internet Protocol (IP) is a network protocol that is responsible for addressing and transmitting data packets over a network such as the Internet. It is the foundation of the Internet, and it is the primary protocol used to transmit data over the Internet or other networks.
IP works on the network layer of the communication stack, and is responsible for delivering data packets from the source device or system to the destination device or system. This is done by assigning a unique IP address for each device or system on the network, and it uses this address to route the data packet to the correct destination.
User Datagram Protocol (UDP)
User Datagram Protocol (UDP) is a Connection Less Protocol that is responsible for transmitting data packets between devices or systems. Unlike the Transmission Control Protocol (TCP), which establishes a reliable connection between a device or a system, UDP does not establish a connection and does not retransmit lost or corrupted packets. This makes it faster than TCP, but it’s less reliable.
UDP is a transportation protocol, which means that it is responsible for managing the transmission of data between devices or systems. It works on the transport layer of the communication stack, and is commonly used in conjunction with the Internet Protocol (IP) to transmit data over the Internet or other networks.
Post Office Protocol (POP)
Post office protocol (POP) is a protocol for receiving email messages from a server. It allows users to download their email to a local device, such as a computer or smartphone, and then access and manage their emailoffline.
POP is an application protocol, which means that it is specific to a particular type of application (in this case, email). It operates at the application level of the communication stack, and is used in conjunction with other protocols, such as the Simple Mail Transport Protocol (SMTP), to transmit email messages between devices or systems.
Simple Mail Transport Protocol (SMTP)
Simple Mail Transport Protocol (SMTP) is a protocol for the exchange of email messages between devices or systems. It is used to send and receive emails, and it defines the format of messages and how to transmit them.
SMTP is an application protocol, which means that it is specific to a particular type of application (in this case, email). It operates at the application level of the communication stack, and this internet message access protocol (IMAP) is meant to transmit email messages between devices or systems.
File Transfer Protocol (FTP)
File Transfer Protocol (FTP) is a protocol for transferring files between devices or systems over a network. It is commonly used to transfer files between computers over the Internet or to transfer files from the local computer to the Web server.
FTP is an application protocol, which means that it is specific to a particular type of application (in this case, file transfer). It operates on the application layer of the communication stack, and is used in conjunction with other protocols, such as the Transmission Control Protocol (TCP), to transmit files between devices or systems.
Hyper Text Transfer Protocol (HTTP)
Hypertext Transfer Protocol (HTTP) is a protocol for transmitting data over the Web. It is used to transfer HTML pages and other web-based content between Web Server and Client such as Web Browser. HTTP is the foundation of the World Wide Web, and it is the primary protocol used to transmit data over the Web.
HTTP is an application protocol, which means that it is specific to a particular type of application (in this case, the Web). It operates at the application level of the communication stack, and is used in combination with other protocols such as the Transmission Control Protocol (TCP) to transmit data over the Internet or other networks.
Hyper Text Transfer Protocol Secure (HTTPS)
Hypertext Transfer Protocol Secure (HTTPS) is a secure version of HTTP, which is the primary protocol used to transmit data over the Web. HTTPS adds an extra layer of security to communication by encrypting the data that is transmitted between the Web Server and the Client, such as a Web Browser. This helps prevent data from being intercepted and read by a third party.
HTTPS is an application protocol, which means that it is specific to a particular type of application (in this case, the Web). It operates on the application layer of the communication stack, and is used in combination with other protocols, such as transport layer security (TLS) or secure sockets layer (SSL), to provide encryption and authentication to transmit data. Internet or other networks.
Telnet Protocol
Telnet is a protocol for remotely accessing and controlling servers or other devices on a network such as the Internet. It allows users to connect to a remote device or system and execute commands as if they were physically present on the device or system.
Telnet is an application protocol, which means that it is specific to a particular type of application (in this case, Remote Access and Control).It operates at the application level of the communication stack, and is used in combination with other protocols such as the Transmission Control Protocol (TCP) to transmit data over the Internet or other networks.
Telnet is a simple and widely used protocol, and it is supported by most operating systems and devices. It allows users to remotely access and control servers or other devices from various devices such as computers, smartphones, and tablets.
Gopher
Gopher is a protocol for accessing and retrieving information over a network such as the Internet. It was developed in the early 1990s as a simple and efficient way of accessing and retrieving information from various sources such as documents, databases and directories.
Gopher is an application protocol, which means that it is specific to a particular type of application (in this case, information retrieval). It operates at the application level of the communication stack, and is used in combination with other protocols such as the Transmission Control Protocol (TCP) to transmit data over the Internet or other networks.
Gopher was one of the first protocols developed to access and retrieve information on the Internet, and was widely used in the 1990s. However, it has since been replaced by other protocols such as the World Wide Web (WWW) and FTP, which provide more advanced features and functionality.
How does the Protocol Work?
Sender and Receiver agree on specific protocols that they will use for communication. This may include configuring the device or system to use the correct protocol and specifying any required parameters or settings.
The sender encodes the data that he wants to communicate according to the rules of the protocol. This may include formatting the data in a specific way, adding a header or other meta data, and/or applying any required encryption or compression.
Sender transmits encoded data to the receiver using the communication channel specified by the protocol. This may include sending data over a network, via cable or any other means of communication.
The receiver receives the transmitted data and decodes it according to the rules of the protocol. This may include parseing data, removing any relevant meta data, and/or applying any necessary decryption or decompression.
The receiver processes the decoded data according to the specific purpose of communication. This may include storing data, displaying it to the user, or performing some other action depending on the content of the data.
If a problem occurs during communication, the protocol can specify how the device or system should handle them. This may include retransmitting lost or corrupted data, negotiating a new set of parameters, or ending communication.
When communication is complete, the protocol can specify how any resources or connections used during communication should clean the device or system.
What is the Use of the Protocol?
Protocols are used in many different contexts to facilitate communication between devices or systems. Some of the main uses of the protocol include:
Enabling interoperability: Protocols help ensure that different devices or systems can communicate with each other, even if they are not specifically designed to work together. This is especially important in situations where different devices or systems are required to transact information, but they may not be directly related or compatible with each other in other ways.
Ensuring Reliability: Protocols can help ensure that communication is reliable, even when errors or other issues arise. For example, protocols can specify how lost or corrupted data should be retransmitted, or how the device or system should interact with a new set of parameters if initial communication is not successful.
Communication Facility: Protocols can make it easier for devices or systems to communicate with each other by defining a common set of rules and conventions that they can use. This can reduce the effort and complexity involved in establishing and maintaining communication between devices or systems.
Ensure safety: Protocols can be used to secure communication between devices or systems by providing stealth(by encrypting the data so that it can only be read by the intended receiver), unity (by ensuring that the data is not tampered with), and authentication (by verifying the identity of the device communicating with each other).
Overall, the use of protocols is essential to facilitate effective communication between devices or systems in many different contexts.
Advantage of Protocol
The advantages of the protocol are as follows –
It has become very easy to exchange data through protocol.
It is through the protocol that the whole world has been able to communicate online today.
Connecting devices to any network is also possible through the protocol.
Disadvantage of Protocol
