Network hubs are a staple in small networks, server farms and workgroups.  The 24 port hub is the biggest of these network hubs and allows 24 Ethernet connections with a single box.  Many 24 port hubs are stackable to allow more than one network hub to be chained together within the same network.

The word Hub is sometimes used by manufactures instead of words like Repeater and Switch even though network hubs and repeaters are the same but switches are not.  Switches play a more active roll than their passive hub cousins.  They allow the passing of data between specific devices and computers connected to the switch.  For instance, one computer can send data to another computer on the switch without sending it to the others that may be connected or causing any interference to other devices on the network switch.  If your 24 port Ethernet hub is actually a 24 port switch you will have this added advantage but a clever hacker could connect two ports on the switch in a loop and cause a network crash which will not happen with a hub since the all devices on a network hub share the same data and cannot be looped.

24 port hubs can do some things that only  a much more expensive 24 port switch can do an inexpensive one cannot.  Any network hub can copy all their traffic and repeat it to multiple receptors and this feature is called port mirroring on a switch but is only available on very high end switches.  The main advantage of hubs over switches is their affordability.

Most 24 port hubs are used to create a Local Area Network (LAN) in small to medium sized businesses.  This allows all the computer users in the business to share information in a closed environment that is productive but still safe from outside intrusion.  Whatever your reasons for needing a 24 port hub, you are sure not to be disappointed and neither will your wallet if you choose one over a 24 port switch.

Many manufacturers make 24 port hubs.
