An intranet is described as a private network that uses the same protocols as the Internet but is only accessible to employees of an organization. Similarities between the two include the use of TCP/IP and ability to access via web browsers. Differences are around access, users, information type, and security. The document also outlines the history and services of both the Internet and intranets, and discusses advantages and disadvantages of using the Internet in libraries.
