Hardware also runs special server software to manage services

Local Area Network (LAN) Data Packets Client Devices Network Server Wireless Access Point Switch Hub Local Area Network (LAN)

Network Server

Web Server Database Server Logon Server File Server Print Server

Local Area Network Wide Area Network (eg the Internet) Server Farm Mail Server Firewall Web Server Client Devices

Stores large number of files for an organisation 3.1 Types of Server File Server Stores large number of files for an organisation Also controls security, such as access rights to files Finally, handles backups in case of accident or disaster

Manages queue of docs for printing 3.1 Types of Server Print Server Manages queue of docs for printing So shares load of print requests across available devices Controls access to printers for users & routes docs to devices

Installs, updates & controls access to programs 3.1 Types of Server Application Server Installs, updates & controls access to programs Includes basic applications such as word processor or email But also specialised software, such as for financial staff only

Manages security & updates to large databases 3.1 Types of Server Database Server Manages security & updates to large databases For example in a school, security means controlling access to staff So teachers update registers & office staff update financial data
