In information technology, a protocol is the special set of rules that end points in a telecommunication connection use when they communicate. Protocols specify interactions between the communicating entities. … Protocols are basically needed because it’s important for the receiver to UNDRSTAND the sender.

Why are protocols important?
Computers make use of protocols as well, to enable them to communicate. Devices need to communicate. … When two devices want to successfully communicate, they must agree to follow some rules about the way they will do it. These are known as protocols.
What is the use of protocol?
Communication protocols allow different network devices to communicate with each other. They are used in both analog and digital communications and can be used for important processes, ranging from transferring files between devices to accessing the internet.
Why are protocols and standards needed?
Protocols are essential for communication, authentication and error detection. … So this is why its necessary to have network standards and protocols because they are what allow different computers from different companies running different software to communicate with each-other making networking possible.
Why is communication protocols important?
Why are communication protocols important? Communication protocols help varied network devices communicate with each other. These assist in the transmission of analog and digital signals and various files and data processes from one device to another.
What are protocols needed?
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.
What is the most important protocol?
Perhaps the most important computer protocol is OSI (Open Systems Interconnection), a set of guidelines for implementing networking communications between computers. Among the most important sets of Internet protocols are TCP/IP, HTTPS, SMTP, and DNS.
How do protocols work?
Each network protocol defines rules for how its data packets must be organized. Because protocols like Internet Protocol often work together in layers, some data embedded inside a packet formatted for one protocol can be in the format of some other related protocol (a method called encapsulation).
What are the types of protocol?
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)
What is the difference between protocol and procedure?
A Protocol defines a set of Procedures or steps to be followed for the accomplishment of a given task. Procedures are task oriented. Procedures provide step-by-step instructions on how to do a task.
Are all standards protocols?
Not all standards are protocols (some govern other layers than communcation). A protocol is not a set of rules. A protocol is the thing those rules describe the rules of. This is why programs implement a protocol and comply with a standard.
What are the two types of standards?
Following are different types of standards:
- Basic standards.
- Normal standards.
- Current standards.
- Attainable (expected) standards.
- Ideal (theoretical) standards.
What is open standard protocol?
«Open Standards» are standards made available to the general public and are developed (or approved) and maintained via a collaborative and consensus driven process. «Open Standards» facilitate interoperability and data exchange among different products or services and are intended for widespread adoption.
How many types of communication protocols are there?
There are three main types of network protocols. These include network management protocols, network communication protocols and network security protocols: Communication protocols include basic data communication tools like TCP/IP and HTTP. Security protocols include HTTPS, SFTP, and SSL.
How many communication protocols are there?
There are two types of communication protocols which are classified below: Inter System Protocol. Intra System Protocol.
What are the different types of communication protocols used in PLC?
Some common protocols used in the industrial arena include:
- Modbus RTU.
- Ethernet TCP/IP.
- Modbus TCP/IP.
