A thin client is a simple computer with basic hardware. In networking, these are used as access points for a user, using the resources of a central server.The simplicity of the hardware means that for many users the cost of allowing them access to the system is reduced. Since they are all connected to a central server, all the resources are managed centrally and it is easier to control access permissions to sensitive data. Finally, it means that problems are easier to track down - if there is a problem at one machine it should be easy to solve since we are working with simpler hardware.
