On a peer-to-peer network, it is also very difficult to implement a good backup system because important documents tend to be stored on different hard disks on different computers. If you do manage to implement a good backup policy, chances are great that after a while some very important documents will not get archived because someone "accidentally" saved them to the wrong location on the network. Peer-to-peer networks also tend to become very costly over time. Since each computer that shares anything to the other computers is a psuedo server, it must be constantly on, and configured correctly. So instead of maintaining a small handful of servers, you must maintain all of the workstations as servers, and as such any downtime with any computer on the network could cause considerable loss of labor or information. The following diagram illustrates all the theoretical connections that are needed for a peer-to-peer network to operate with just 5 computers. Note that this illustration does not represent physical network connections, but the theoretical network connections the operating system needs to operate the network properly. The computer operators of a peer-to-peer network must also be well acquainted with the intricacies of running a computer in order for them to be able to do any work with the network. The users must be able to locate the different shares on the network, and be experienced enough to work through small problems, such as password problems or network mapping problems. As a side note, I have been in offices that used such complex drive mappings on a peer-to-peer network that they had a checklist showing which computers to turn in a certain order for the network to work properly. Final Words on Peer-to-peer Networks Peer-to-peer networks can be implemented with very little investment costs, but in order for the network to work properly, the users must be very experienced with computers, and strict guidelines must be implemented and followed in order for the data to remain secure and archived properly. In my experience, peer-to-peer networks tend to become more of a headache instead of a help after about 6 computers, especially if your company has a moderate employee turnover. Client-Server Networks Overview of a Client-Server Network The Client-Server network model usually consists of one or more server computers that provide services and information to a number of workstation computers. These services can consist of many different roles, including: file services, web services, email services, domain name lookup services, document version system services, Internet sharing services, etc. A great example

of the Client-Server network model is actually the World Wide Internet. On the Internet clients, or computer with web browsers, access web sites that are hosted on servers.

    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.
