The last piece of the networking puzzle is called a hub. A hub is a box that is used to gather groups of PCs together at a central location with 10BaseT cabling. If you're networking a small group of computers together, you may be able to get by with a hub, some 10BaseT cables, and a handful of network adapters.
Larger networks often use a thin coax "backbone" that connects a row of 10BaseT hubs together. Each hub, in turn, may connect a handful of computer together using 10BaseT cabling, which allows you to build networks of tens, hundreds, or thousands of nodes.
Like network cards, hubs are available in both standard (10Mbps) and Fast Ethernet (100Mbps) versions.
As companies rely on applications like electronic mail and database management for core business operations, computer networking becomes increasingly more important. This tutorial helps to explain Ethernet and Fast Ethernet, which are two of the most popular technologies used in networking.
