Final answer:
An extranet does indeed use Internet protocols to allow controlled access to a company's data by external parties. This is true and is essential for secure information sharing with a company's external stakeholders like customers and suppliers.
Step-by-step explanation:
The statement that an extranet uses Internet protocols to establish limited access to company data by the company's customers and suppliers is true. An extranet is an extension of a company's intranet that is available to users outside the company, such as customers, partners, vendors, or suppliers, but provides controlled access to company information. It is built using the same technologies as the internet, like TCP/IP protocols, and serves the purpose of facilitating secure and controlled sharing of business information.
The historical context of web technology starting with ARPANET, which led to the development of the internet as we know it, laid the groundwork for various web-based services, including the concept of an extranet. Ted Nelson's ideas of hypertext and the web contributed to how information would be interconnected on the internet, influencing how documents and data are accessed and shared, which is a crucial aspect of what extranets do today.
