2 L ESSON AIMS By the end of this lesson you will be able to:  Describe what a peer to peer network is  Describe what a client server network is  Discuss the differences between them

3 C LIENT AND S ERVER N ETWORKS You are working on a client and server network Your machine is a CLIENT Your documents are stored and internet access is managed through the schools SERVER You connect to a server to use its resources This can vary depending on the server Might just be to store files…

4 A SAMPLE C LIENT S ERVER NETWORK Client E-mail Server File Server Web Server

5 W HAT CAN A SERVER DO ? Servers can perform multiple roles – some are They can run email servers They can store files Control Internet Access Host Web Sites Control printing for multiple computers

6 P EER TO P EER N ETWORKS You can run a peer to peer network A peer to peer network is where each computer shares the functions/files of a network. Peer to peer networks have advantages :  Each computer has its own backing storage so does not rely on an expensive server.  No expensive server hardware or software to purchase  No complex server software to setup

7 U SES OF P EER TO P EER N ETWORKS Distributed downloading Where instead of downloading from one central location you download pieces of a file from multiple machines Can be used for legal AND illegal purposes The technology is legal! The files being shared may not be!
