Hubs also often come with a BNC and/or AUI connector to allow connection to legacy 10BASE2 or 10BASE5 network segments. The availability of low-priced network switches has largely rendered hubs obsolete but they are still seen in older installations and more specialized applications.
[http://en.wikipedia.org/wiki/Network_hub More on MediaWikiWikipedia...]
=== Network Switch ===
The term Network switch does not generally encompass unintelligent or passive network devices such as hubs and repeaters.
The first Ethernet switch was introduced by Kalpana in 1989. [http://en.wikipedia.org/wiki/Ethernet_Switch More on MediaWiki Wikipedia ...]
=== Network Router ===
A router (pronounced /'rautər/ in the USA, pronounced /'ru:tər/ in the UK, or either pronunciation in Australia) is a computer whose software and hardware are usually tailored to the tasks of routing and forwarding information. [http://en.wikipedia.org/wiki/Router More on MediaWiki Wikipedia ...]

* Show active sockets, interfaces, and routing information
* Connect to hosts on your local network
* Connect to hosts on different networks with specific routes/gateways
* Connect to the Internet - Default Gateway
Sysconfig network configuration
* To start the the program:
** click on the menu bar "system->Administration->Network"

* Note that the repository for the NetworkManager source code has been moved from cvs to subversion (svn). Details can be found [http://www.gnome.org/projects/NetworkManager/developers/ here].
===NetworkManager===
** A service daemon that attempts to keep an active network connection available at all times.
** makes networking configuration and setup painless and automatics as possible.

* NetworkManager Administration
** Check the service daemon status
[root@fc9 ~]# service NetworkManager status
NetworkManager (pid 2239) is running...
** Stop the service daemon (Don't do this if you are connected to the system remotely. If you do, you will get cut off.)
[root@fc9 ~]# service NetworkManager stop
Stopping NetworkManager daemon: [ OK ]
** Start he service daemon
[root@fc9 ~]# service NetworkManager start
Setting network parameters... [ OK ]
Starting NetworkManager daemon: [ OK ]
