There's one major distinction between an intranet and the Internet: The Internet is an open, public space, while an intranet is designed to be a private space. An intranet may be accessible from the Internet, but as a rule it's protected by a password and accessible only to employees or other authorized users. From within a company, an intranet server may respond much more quickly than a typical Web site. This is because the public Internet is at the mercy of traffic spikes, server breakdowns and other problems that may slow the network. Within a company, however, users have much more bandwidth and network hardware may be more reliable. This makes it easier to serve high-bandwidth content, such as audio and video, over an intranet.
Difference between Tacit knowledge and Explicit Knowledge
Tacit knowledge is the knowing of things without knowing how you know; explicit knowledge is the knowing of things that you can explain. For example, most people can speak grammatically without being able to explain the rules of grammar. This is Tacit knowledge. Explicit knowledge is that answer to 2X2. In Project Management, Tacit Knowledge is the knowledge your co-worker knows, but isn't codified or written down; while Explicit Knowledge deals with knowledge that is written down and structured. For example, your co-worker knows how to fix Word when it chokes on an important document; but she is the only one. This is the Tacit Knowledge that Project Management tries to root out and codify. Once that knowledge is written down and saved somewhere it becomes explicit. http://wiki.answers.com/Q/What_are_the_difference_between_tacit_and_explicit_knowledge
