I'm in charge of some of the technical training at our programming company. That includes getting some of the project managers up to speed with basic information technology.
I bought a university Management Information Systems textbook, and I was very surprised to find a long discussion about network topologies:
- Star topology networks and how they require a central host computer
- Ring networks, and how they send a token around a ring
- Bus networks, and how they must always be terminated both ends
- Tree networks which had workstations at the bottom level of the network, minicomputers in the middle, and servers at the top.
This information seems extremely out-of-date for a book that was published in 2012. As I understand networks, the text applies very much to coaxial cable networks (especially ring and bus).
However, these days twisted pair Ethernet (with the occasional wireless router) is used for office networks almost exclusively. The only relevant topology seems to be tree.
Is information about these network topologies still relevant, and if it is, how does it still apply?
