<h3>What is file?</h3>
A file is a computer system container for storing data. Files used in computers are similar in characteristics to paper documents used in libraries and office files. There are different types of files like text files, data files, folders, binary and graphic files and these different types of files store different types of data. A computer's operating system can store files on optical discs, hard drives, or other types of storage devices.
In most operating systems, a file must have a unique name within a specific directory. However, when creating a file name, some characters are considered illegal and therefore cannot be used. A file name consists of a name with an extension, also known as a file extension. The file extension is the two to four characters after the period of the full file name.

Similarly, when the all the broadcasters in one location are each trying to send messages to different receivers at another given location, there would be potential for network congestion and it would be difficult to send information through the network
When there is need for priority service the presence of a network layer is needed in the network
However, when the above functions performed by the network layer is not required, then, the network layer can be excluded, such as the communication between layers 4 - 7 of the OSI model
