- 7. Peer to Peer Advantages Easy to install No server needed Each user has control No administrators needed Disadvantages Security & backups must be applied individually Many passwords needed Reduced password security Reduced machine performance No central control Networking Concepts – Eric Vanderburg ©2005
- 8. Client Server Advantages Centralized Disadvantages security & backups Faster access Single password Better password security Central point of failure Administrator required Server and server software required Networking Concepts – Eric Vanderburg ©2005
- 9. Models Centralized Computing Easy to backup, Good security, low cost Slow network, fewer options Distributed Computing Quick access, multiple uses Virus susceptibility, backup difficulty, file sync Collaborative Computing Project RC5 & OGR (http://www.distributed.net) Seti@Home (http://setiathome.ssl.berkeley.edu/) Networking Concepts – Eric Vanderburg ©2005
