Comment:
readability, typos, formatting.

- Debian Edu is an awesome Debian Blend that just works out-of-the-box. Their developers have been working for years and have burned lots of neurons developing it for you. Even though, some work is still necessary to make it work at your place. To succeed, make sure you take enough time to read and understand the following page to bring your Debian Edu network up and running. You actually need few knowledge so let's begin acquiring it!
+ Debian Edu is an awesome Debian Blend that just works ''out-of-the-box'' once you learn what it can do, and how to use it. Their developers have been working for years and have burned lots of neurons developing it for you. Even so, some work is still necessary to make it work at your place. To succeed, make sure you take enough time to read and understand the following page to bring your Debian Edu network up and running. You need a little technical knowledge, so let's begin acquiring it!

  '''Gateway'''<<BR>>
- It is a node on a TCP/IP network that serves as an access point to another network. Most of the people with Internet connection at home have a modem router that serves as a gateway to the Internet. On medium to large intranets it will more commonly be a router that in turn receives routed traffic from another router.<<BR>>

- '''WARNING:''' be aware that on a Debian Edu network this gateway must be able to serve using "class A" ip's (typically 10.0.0.1 or similar). At home you will normally use "class C" (typically 192.168.1.1 or similar). Normally those routers are more expensive because they are sold under a "business brand". As an alternative, it is possible to use dd-wrt on suitable hardware like (for example)the Linksys WRT54GL router.

  '''Network Switch'''<<BR>>
- It's a computer networking device used to connect devices on a network. It is capable to send specific packets to the specific hosts that requested them.<<BR>>

  '''Main server (Tjener)'''<<BR>>
- The main server or Tjener (which is the norwegian word for server) contains information about users as well as their files and it runs most of the services in a Debian Edu network. Even though, most services can easily be moved to a different machine if necessary. '''There must be only one main-server in the network. You can install both a main-server and an LTSP server on the same machine.'''

  '''LTSP server'''<<BR>>
  An LTSP server is a powerful machine that does most of the work by running all the processes and serving the result to the thin clients that are connected to it through a switch. It also provides the file system for diskless workstations.<<BR>>
  It provides file central storage, central user authentication and generally they do not offer any services to the rest of the network. There can be multiple LTSP servers in the network and they possibly may be used to share printers.

  '''Thin client'''<<BR>>
- A thin client is a computer terminal with a monitor, mouse and keyboard that can be an old weak machine (A 133Mhz Pentium I is enough) without even hard disk. Ideally the network card should be bootable (by PXE or Etherboot) but, if not, older cards can be obtained for just a few Euro. Alternatively you can boot them using a Bootdisk. It's function is to draw the result of the thin-client server computation and to provide mouse and keyboard input.

  '''Workstation'''<<BR>>
- It is regular computer where applications are installed and run locally. It allows faster startup times and access to local devices such as CD-writers but has a big maintenance cost as any workstation's operative system and software must be installed, maintained and configured individually.

  '''Diskless Workstation'''<<BR>>
  It is a solution between a thin client and a workstation. It boots from the network, mounts its root file system from its next-server, and runs all applications on the local hardware. You can think about it like a regular workstation with a very long hard drive cable. '''NOTE:''' Diskless workstations are also marketed using the term "!LowFat Clients" or "Halfthin Clients" or "stateless workstations".
