- No network manager needed: all users take own responsibility
- Knowledge: users need more IT knowledge
- Easy to set up: simplest form of computer network.
- No reliance on server: no worry about break down
- Security: poor
- Backups not made centrally: have to do own
- CLIENT SERVER: used in large orgs. Has a central server. Server carries out many functions
- More expensive: servers
- Cost of set up and maintenance
- One machine more important than the rest

- If server breaks down network in unusable
- Users need little specialist knowledge as admin is performed centrally
- Back ups done centrally
