Select the true statement about network protocols.

·        A protocol is a rule for transmitting data between computing devices.

·        The primary function of a protocol is to compress data to reduce storage requirements.

·        Protocols determine the best method for resolving errors with data encryption.

·        Every computer uses the same protocol to communicate, regardless of the network type.

Answer:- The correct answer is 1. A protocol is a rule for transmitting data between computing devices.

Explanation:

Network protocol is a set of standards regulating how data is passed from one device to another in a network. Protocols define such things as what the format of messages sent and received should be or how to initiate a message, indicate that it is finished being transmitted, showed where errors have occurred in transmission and know when there has been an error with lost data.

Protocols allow devices that may have completely different hardware and software to communicate by providing a universally accepted standard for data exchange. If protocols were not to be there, the devices would never understand each other’s digital language.

Some of the network protocols include TCP/IP which describes internet communication, WiFi protocol such as 8021.1g that enables wireless networking, File Transfer Protocol FTP for file transfers and Hyper Text transfer over HTTP /HTTPS for web traffic. Each has its specific role in standardizing data transfer for different types of networks and applications.

Protocols run across several layers within a network. Lower level protocols determine raw data over cables and airwaves physically transmitted while higher ones deal with the more intricate communications such as correct delivery verifications or package re-requests. Different protocols are utilized to finally establish end-to-end communication between devices.
