This is my presentation for CST209 Advanced Computer Networking Class. This is the only way I am able to upload this, as I am apparently not intelligent enough to make it work with compressing it. I have never been able to understand compressing fully...

1. Client/Server Apps
from BIG to small
(Also Peer-to-Peer)
By Nick Weber

2. What are they? Client/Server
 Client/Server Applications go from the client side, and
send the information to a centralized server.
 Different from Peer-to-Peer
 Will discuss P2P in later slides
 Your Internet Browser is a Client/Server application!

3. Where they would work
 Typically, bigger companies will use Client/Server model
for their networking.
 Every Web browser is a Client/Server application.
 Email clients are Client/Server

4. Examples of Client/Server
Applications
 The entire Internet is a giant Client/Server App, in the
form of TCP/IP
 Web Browsers that access the Internet are Client/Server
applications too
 Email clients use this C/S method
 Network printers use this application
 A bigger example would be a company that stores all of
its’ data on a big centralized server

5. Peer to Peer (P2P applications)

6. What are they? Peer-to-Peer
 The computers share direct information with each other,
without the use of a centralized server.
 This means the computer does not lose data if another
computer crashes, like they would if they were using a
server
 This also mean less down time due to inability to
connect

7. How they work exactly (P2P)
 Rather than the centralized server of a Client/Server
application, computers connect over a network to
another computer directly.
 This converts to faster transfer times
 This also comes with more risks

8. Where they would work (P2P)
 Smaller companies might be able to make use of this
model, as well as websites that share files. Another use
for this is video or voice chat over computers.
 Schools could also make use of Peer-to-Peer software,
for computer supervision.

9. Examples of P2P Applications
 Skype uses P2P
 Bitcoin, a popular internet currency
 File sharing sites (Even illegitimate ones!)

10. Pros of Client/Server Applications
 Fast and Efficient
 Mostly cost effective
 Easy to Maintain

11. Cons of Client/Server
Applications
 Costs become higher the more clients you have
 Risk of Server crashing and losing data, time, and
money

12. Pros of Peer-to-Peer Applications
 Applications easy to install and configure
 Possibility to be faster
 No risk of server crashing and losing data
 Cheaper than Client/Server applications
 No need for System Administrator

13. Cons of Peer-to-Peer applications
 Security risks with physical security.
 Viruses are easily transferred
 Data recovery is nearly impossible
 Used for illegal purposes a lot of times

14. Conclusions
 In conclusion, it would be good to learn about both
Client/Server and Peer-to-Peer applications
 Both could help you in future careers, depending on
where you work
 Client/Server will be in bigger companies, P2P MIGHT be
in smaller companies
