The document discusses the history and definitions of the Internet, intranets, and extranets. The Internet began in the 1960s as the ARPANET network for researchers and has grown exponentially over the decades. An intranet is a private network that connects computers within an organization, while an extranet allows selective internal information from the intranet to be accessed by outside partners and remote employees. Key differences are that the Internet is largest but least secure, an intranet is private but smaller, and an extranet provides security with limited external access. In conclusion, while each has advantages and disadvantages, the systems differ mainly in their scope and levels of access.
