STANDARDS AND PROTOCOLS

 In computer networks, different devices need to communicate with each other. A protocol is a set of rules that govern how this communication happens. A protocol includes the format of the data being sent, the meaning of each part of the data, and the timing of when the data is sent.

The format of the data refers to the order in which the data is presented. For example, a protocol might say that the first part of the data is the sender's address, the second part is the receiver's address, and the rest is the message being sent.

The meaning of each part of the data refers to what that part of the data represents. For example, an address might identify the final destination of the message or the route to take to get there.

Timing refers to when the data should be sent and how fast it can be sent. If data is sent too quickly for the receiver to process, some of the data might be lost.

Overall, protocols help ensure that devices can communicate with each other effectively and efficiently.

Standards are rules that equipment makers and service providers follow to ensure that their products can work together and communicate with each other. These rules help create fair competition and make it easier for people and organizations to connect and share information. There are two types of data communication standards: de facto (based on what is commonly used) and de jure (based on laws and regulations).

Standards are important because they provide a common framework for communication and interoperability between different equipment manufacturers and service providers. They ensure that products and services are compatible with each other, allowing for smooth and efficient communication and data transfer. This can be especially important in industries such as telecommunications and information technology, where the ability to connect and communicate with others is essential.

There are two main types of data communication standards: de facto and de jure. De facto standards are established through common use and market acceptance. They are not formally recognized by any official organization or government agency, but rather emerge naturally as a result of widespread adoption by industry players. Examples of de facto standards include the QWERTY keyboard layout and the USB port.

De jure standards, on the other hand, are established through formal regulation or legislation by government agencies or standards organizations. These standards are legally binding and are enforced by law. Examples of de jure standards include the 802.11 family of wireless networking standards, which are developed and maintained by the Institute of Electrical and Electronics Engineers (IEEE), and the International Telecommunication Union (ITU) standards for telecommunications.

Overall, standards play an important role in ensuring that different systems and technologies can work together seamlessly, regardless of the manufacturer or service provider. They are essential for creating a fair and competitive marketplace, and for enabling international communication and collaboration.
