Two Questions
Is there another word for mesh?
e.g mesh topology
If the ISA bus on a AT system in 16 bit then how much bits is an ISA bus on an ATX system?
From what I know ISA only provides 8 or 16 bits, right?
Thanks in advance!

It is a 16-bit bus, but it does accept 8-bit cards.
If you can get your hands on some motherboards, you will instantly see the difference in AT and ATX-- AT has a larger connection for the keyboard, and that keyboard connector is the ONLY connector physically integrated onto the board. Serial, parallel, USB, video, game and mouse connectors are usually attached with small ribbon cables. Not all of those connections will necessarily exist either.
With ATX you will find most of those items on the back of the board (some boards include so many features that they don't fit, so the lesser used ones --game and serial-- are ribboned). Anything that isn't attached is likely very new technology or older stuff (again, game and serial) that is essentially superceded by USB.
As for mesh, I don't think you will see that on Core.. I hadn't heard of it until a couple weeks myself, and the way it was diagrammed just confused me with another topology (I won't say which, so as to save you from the same). Mesh is also very expensive to deploy over anything but the tiniest of networks (each machine is connected directly to every other machine-- that is a lot of NICs to purchase!). For example, to add a single machine to an existing 3 user LAN requires 3 NICs in the new PC, plus three more NICs to connect the other machines to it. However this setup means there is no single point of vulernability to the LAN.
The only time you'll really see an 8 bit ISA card/slot is on very ancient machines. The standard was origingally developed as an 8 bit standard then improved to 16 bit later.

The main reason I love ATX is because I don't have to deal with expansion cards sitting right over the CPU.
