computer with a zip drive to take work home. All of these computers are networked together, with no central server. The secretary uses the zip drive through the network to backup important documents, and also uses the ink jet printer on the accountant's computer to print out fliers. The accountant uses the laser printer on the secretary's computer to print out checks, accesses some important documents on the secretary's computer, and backs up the accounting data on the zip drive on the owners computer. The owner uses both printers on the other computers, and accesses important documents on the secretary's computer. All of the computers share Internet access through the secretary's computer. All of this gets done with no passwords or user names since all the shared devices use no access control, or other type of security measure. Also in order for the accountant's computer and the owner's computer to be able to read the companies important documents, the secretary's computer must be turned on first. The Benefits of a Peer-to-peer Network Peer-to-peer networks are very cheap to implement because more than likely the Operating System software you have installed on your computers should have the ability to share items with other computers on the network, even though the feature may be limited. Nearly all of the most popular desktop Operating Systems have this feature, including Microsoft Windows and Apple's Mac OS, as well as Unix like OS es, such as Linux and the BSD s. So the only cost will be the networking hardware (cards, wiring, hubs or switches), and the labor to configure the workstations for this type of network sharing.

Even though a peer-to-peer network is very cost effective up front, there are a number of downsides you must consider before implementing this type of network. Without a central server, it is very difficult, or nearly impossible to secure this type of network in any way. You can implement passwords on each different network share, but in order for the network to usable, the exact same username and password must be entered into each computer acting as a server. Thus, to change a password for a user could literally take hours of work, especially if the network consists of computers located in different buildings or different floors. Because of this, what usually happens with peer-to-peer networks is that passwords are implemented to begin with, but after time, either everyone starts using the exact same username and password, or the passwords end up becoming blank, or the network shares are configured to allow anyone access without a username or password. In any of these cases, security is pretty much non-existent, which can become a huge problem, especially if your network has access to the Internet.

    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.
