Protocol is a set of rules that governs the communication between devices in a computer network. The protocol determines the format and sequence of the data packets that are sent between the devices.
Protocols can be classified into two categories:
– LAN Protocols: These are the protocols that are used for communication within a Local Area Network (LAN). The most common LAN protocol is Ethernet.
– WAN Protocols: These are the protocols that are used for communication over a Wide Area Network (WAN). The most common WAN protocol is the Point-to-Point Protocol (PPP).
There are many different protocols that can be used in a computer network. Some of the most common protocols are:
– TCP/IP: The TCP/IP protocol is the most common protocol for communication on the Internet. It is a suite of protocols that includes the Transmission Control Protocol (TCP) and the Internet Protocol (IP).
– Ethernet: Ethernet is the most common LAN protocol. It is a standard protocol that is used to transmit data packets over a LAN.
– HTTP: The Hypertext Transfer Protocol (HTTP) is the protocol that is used to transmit data over the World Wide Web.
– FTP: The File Transfer Protocol (FTP) is a protocol that is used to transfer files between devices on a network.
– DNS: The Domain Name System (DNS) is a protocol that is used to map domain names to IP addresses.

WHAT IS protocols in computer networks?
A protocol is a set of rules that govern how computers communicate with each other over a network. They are essentially the language of networking, and allow devices to talk to each other in a standardized way.
There are many different kinds of protocols, but some of the most common ones include:
– Transmission Control Protocol/Internet Protocol (TCP/IP): This is the standard protocol used for communication over the internet.
– Hypertext Transfer Protocol (HTTP): This is the protocol used for communication between web browsers and web servers.
– Simple Network Management Protocol (SNMP): This is a protocol used for managing network devices.
Each protocol has its own set of rules, which can be quite complex. However, by understanding the basics of how protocols work, you can greatly improve your understanding of networking as a whole.
What is protocol and it types?
What is Protocol?
Protocol is a set of rules that governs the interactions between two or more devices in a communication network.
Protocols are essential for communication networks to function. They define the format and order of messages that are sent between devices, as well as the actions that should be taken in response to specific messages.
There are a variety of different protocols that can be used in communication networks. The most common protocols are:
– Transmission Control Protocol (TCP)
– Internet Protocol (IP)
– Hypertext Transfer Protocol (HTTP)
Transmission Control Protocol (TCP)
TCP is a connection-oriented protocol that ensures the reliability of data transmission between two devices. It establishes a connection between the devices, and then ensures that all messages sent between them are received and accurately interpreted.
If a message is lost or corrupted during transmission, TCP will automatically retransmit it. This ensures that data is always delivered accurately and reliably.
Internet Protocol (IP)
IP is a connectionless protocol that provides a way to deliver packets of data between devices on a network. It does not guarantee the delivery of packets, or the order in which they are delivered.
However, IP is a very efficient protocol, and is the backbone of the Internet. It is used to deliver packets of data between routers, and is responsible for the vast majority of data transmission on the Internet.
Hypertext Transfer Protocol (HTTP)
HTTP is a protocol that is used to transfer data between a web server and a web browser. It defines the format of messages that are sent between the devices, as well as the actions that should be taken in response to specific messages.
HTTP is used to transfer both text and multimedia content between devices. It is the most common protocol for transferring data over the Internet, and is responsible for the majority of web traffic.
What protocol means?
Today, most of our communication is digital. We send text messages, emails, and WhatsApp messages. We use the internet for banking, shopping, and researching. And all of this communication happens thanks to protocols.
But what do protocols actually do? And what do they mean for you and your online life?
Protocols are a set of rules that govern how computers communicate with each other. They determine the format of the messages, the order in which they are sent, and the way in which they are interpreted.
Protocols are essential for communication on the internet. They ensure that all messages are sent and received correctly, regardless of the type of computer or operating system involved.
Without protocols, the internet would be a mess. Messages would be sent in random order, and interpretation would be a total guesswork.
Protocols are also essential for security. By using standard protocols, computer systems can be sure that messages are being sent and received by the correct parties, and that no malicious messages are being intercepted.
There are a variety of different protocols, each designed for a specific task. The most common protocols are HTTP, TCP, and UDP.
HTTP is used for web browsing and downloading files. TCP is used for transferring data between two devices, and UDP is used for streaming video and audio.
There are also a range of secure protocols, such as HTTPS and SSH, which are used for banking, shopping, and other sensitive activities.
So, next time you go online, take a moment to appreciate the protocols that are making it all possible. Without them, the internet would be a very different place!
WHAT IS protocols and example?
Protocols are a set of rules that govern how communication takes place between devices on a network. By using protocols, devices can communicate with each other regardless of their manufacturer or operating system.
One of the most common protocols is TCP/IP, which is used to connect devices to the internet. TCP/IP is a suite of protocols that includes the Transmission Control Protocol (TCP) and the Internet Protocol (IP). TCP provides a reliable connection between devices, while IP handles the actual delivery of data.
Other common protocols include the Hypertext Transport Protocol (HTTP), which is used to transfer web pages and other content, and the Simple Mail Transfer Protocol (SMTP), which is used to send and receive email.
Protocols can be implemented in a number of ways, including as a stand-alone protocol stack, as part of a larger protocol suite, or as part of an operating system. Protocol stacks are used to provide an interface between devices and the network, while protocol suites provide a collection of related protocols that can be used together. Operating systems include a number of built-in protocols that allow devices to communicate with each other and with the network.
Protocols can also be implemented in firmware or software. Firmware is a type of software that is embedded in a device, while software is a type of application that is installed on a device.
Protocols are used to provide a common language that devices can use to communicate with each other. By using protocols, devices can exchange data regardless of their manufacturer or operating system.
What are the 7 protocols?
There are seven main computer networking protocols that are used in most cases. The protocols are: Transmission Control Protocol/Internet Protocol (TCP/IP), File Transfer Protocol (FTP), Simple Mail Transfer Protocol (SMTP), Hypertext Transfer Protocol (HTTP), Secure Shell (SSH), Telnet, and Domain Name System (DNS).
TCP/IP is the most common protocol and is the foundation of the Internet. FTP is used to transfer files between computers, SMTP is used for sending email, HTTP is used for browsing the web, SSH is used for secure communication, Telnet is used for logging in to remote computers, and DNS is used to map domain names to IP addresses.
What is the role of a protocol?
A protocol is a set of rules that govern how communication takes place between devices on a network. The role of a protocol is to ensure that all devices on the network can communicate with each other effectively.
Protocols can be implemented in a number of ways, including as a set of rules that are embedded in hardware, as software that runs on a specific device, or as a set of standards that are published and maintained by a standards organization.
Protocols are used in a variety of networking applications, including local area networks (LANs), wide area networks (WANs), and the internet. Some of the most common protocols include the Transmission Control Protocol (TCP) and the Internet Protocol (IP), which are used to transmit data over the internet.
Protocols can be used to facilitate a variety of communications tasks, including:
– Communicating between two devices
– Transferring data between devices
– Establishing a connection between devices
– Providing information about the status of a connection between devices
– Resolving conflicts between devices
What are the 4 types of protocol?
There are four types of protocol: control, data, management, and presentation.
Control protocol is responsible for ensuring that messages are correctly formatted and sequenced, and that all packets are delivered. It also manages the flow of traffic between devices.
Data protocol handles the transmission and receipt of data packets.
Management protocol provides functions such as addressing, error detection and correction, and flow control.
Presentation protocol manages the translation of data between devices with different encoding formats.
