Answer:
Each variable is named so it is clear which variable is being used at any time. It is important to use meaningful names for variables: ... The name given to each variable is up to the programmer, but ideally a variable name should have meaning, ie it should reflect the value that it is holding.
Variables make code more than a static set of instructions. They allow logic to occur, enabling developers to measure time, analyze data, and customize the program to the user. Variables are so important to the code that they deserve a good name that accurately describes their purpose

Extranet
An extranet acts as a shared network, disseminating information present on the intranet. That is, if a private intranet shares some of its content with other users (be they sellers, customers, etc.), this shared network is what we call the extranet.
Intranet
Today, companies are looking for tools and methods to align internal communication, reduce costs, and centralize information and files. The intranet is one of these tools, which works restricted to a specific audience, such as a company. This way, collaborators can access it with their specific username and password.
The intranet is, then, a closed and internal network, and still allows the use of more communication protocols besides HTTP. Intranet access is typically done on a local server and a local network, which we call LAN, which means Local Area Network installed within the company.
This internal network connects users, allowing information exchange, file and document management, centralizing communication between users. With this tool, you can quickly and securely and efficiently connect companies and departments.
