location and we need to take some of the information within our intranet and make it available through theInternet to that partner organization. To do this, we could establish an extranet that is connected to the Internet. We implement controls on the extranet to make sure that this partner organization over here can only access the information that we want it to. Any other devices that are not part of the extranet--they don't belong to the authorized partner corporation-- would not be allowed to access the resources within my extranet. The Internet is a large public network, while intranet is a private network that uses Internet technologies but is only available to users within a particular organization.An extranet is a private network that is made available to authorized external users but not to the general public. Summary 10:39-10:52 That's it for this lesson. In this lesson, we introduced you to many different networking terms. We talked about addressing, we talked about LANs, we talked about MANs, we talked about WANs. We also talked about the Internet, we talked about intranets, and finally, we ended this lesson by talking about extranets. A network is a group of computers that can share information through their interconnections. A network is made up of the following components: Computers (often called nodes or hosts ) Transmission media—a path for electrical signals between devices Network interfaces—devices that send and receive electrical signals Protocols—rules or standards that describe how hosts communicate and exchange data Despite the costs of implementation and maintenance, networks actually save organizations money by allowing them to: Consolidate (centralize) data storage Share peripheral devices like printers

Increase internal and external communications Increase productivity and collaboration There are several ways to classify networks. The following table lists several ways to describe a network: Type Classification Description Host Role Peer-to-Peer In a peer-to-peer network, each host can provide network resources to other hosts or access resources located on other hosts. Each host is in charge of controlling access to those resources. Advantages of peer-to-peer networks include the following: Easy implementation Inexpensive Disadvantages of peer-to-peer networks include the following: Difficult to expand (not scalable) Difficult to support Lack centralized control No centralized storage Client-Server In a client-server network, hosts have specific roles. For example, some hosts are assigned server roles, which allow them to provide network resources to other hosts. Other hosts are assigned client roles, which allow them to consume network resources. Advantages of client-server networks include the following: Easy to expand (scalable) Easy to support Centralized services Easy to back up Disadvantages of client-server networks include the following: Expensive server operating systems Extensive advanced planning required Geography Personal Area Network (PAN) A personal area network

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
