  Client technologies are described in the following order. Graphic terminals Citrix and FreeNX, thin clients with X Windows, thick clients with Linux and Windows, client in between with Linux, and laptops. Then follow examples of what is common to use of server machines in various concern-oriented installations. A key factor for calculating costs is the number of concurrent users and the number of servers. Centralized management of computer equipment at several schools may in practice be compared with how the operation of ICT systems is done in larger companies. Often schools have more computers than the rest of the council's activities. It can quickly lead to a doubling of the number of employees in IT services in the municipality if you do not think things through in what one chooses for client solutions in schools.
  
- Citrix is the most known product for '''grafical clients'''. The company makingthis is product was established in 1989. The first graphical clients was made for the operating system OS/2. First Windows product was launched with NT 3.51 in 1995. There are several competing products to Citrix. One of the most successful is the NX technology. Briefly, you may run applications from a server with Citrix or NX. The screen is exported over the network from a server to a graphical terminal on a thick client.

  '''Grafical clients''' have the strength that it is the same what kind of operating system running on the client. Applications on the server, you may use anyway. One can run standard office programs and client emails over an ISDN line with 64 kbps. That said, there are limitations in graphic software, whether it is used with multimedia or interactive graphics. The solution can quickly become of no practical use if a municipality distribute 30 or 50 graphic terminals at 5-6 schools with broadband with 2-8 Mbps. With this capacity one can not run interactive graphical applications. The Internet will be filled up with traffic, and Citrix client disconnects from the server machine.
