File Servers
When a network is based on a central file server, networked computers can share resources such as printers, and users can store their files in a secure central location. The file server offers services to all users, but each workstation on the network does its own processing. For example, if a user wanted to use a spreadsheet she would run the spreadsheet on her own PC, but would be able to save her work in her home directory on the server, and use a shared network printer.
File servers usually manage:
- user authentication through login names and passwords
- assigning rights to users (e.g. which directories they have access to)
- controlling print queues
- sending files to users
- virus scanning
- internet access
- allocation of IP addresses
- logging user actions and errors
- data backups
