What is thin client

Thin client

Clients are classified according to their functionality. A distinction is made in the client-server concepts in terms of the division of tasks between thin clients or lean clients, fat clients and rich clients, which are also referred to as smart clients.

The concept of thin clients

Thin clients (TC) are network computers (NC) that comply with specific hardware guidelines. The guidelines for equipping thin clients have been specified by several hardware manufacturers and include a screen resolution of at least 640 x 480 pixels, a keyboard, a computer mouse and sound capability. Hard disks are not required but are also not explicitly excluded. The operating system and the application software are located on central servers from which program updates and system administration are also carried out. As a result, system reliability is better and maintenance costs are lower. In addition, the possibility of catching viruses is relatively low. In order to better classify the performance of thin clients, they have been divided into several categories. A distinction is made between thin clients, mobile clients, hybrid clients and complex hybrid clients.

A pure thin client is a window terminal that is designed for server-based computing or for remote applications. Such a terminal is usually used stationary and is suitable for stationary office workers and teleworkers. To access the terminal server, the relevant access protocols such as Remote Desktop Protocol (RDP) or Adaptive Internet Protocol (AIP) must be installed on the thin client and the components must support X11 or terminal emulation. The remote access parameters are protected either in the Windows Terminal Server (WTS) or in the remote access device and by passwords.

The mobile thin client

The mobile client in the form of a notebook is ideal for managers and travelers as the user can access company resources and work locally. The user accesses the company server via a virtual private network (VPN).

The simple hybrid client describes a managed personal computer (PC) whose applications are processed via the company server and on which certain special applications have to be executed locally. The complex hybrid client is comparable to the simple hybrid client with the difference that it executes several applications locally and has its own local peripherals.
