Upgrading a 10BaseT network to 100BaseT is not a small process. What are the three things you need to do to accomplish this?
First, you need to make sure you have CAT 5 cable or better. This part isn't a big deal because almost all network cables installed in the past decade are at least CAT 5. Second, you must replace all the old 10BaseT NICs with 100BaseT NICs. Third, you need to replace the 10BaseT hub or switch with a 100BaseT hub or switch. Making this upgrade cost a lot in the early days of 100BaseT, so people clamored for a way to make the upgrade a little easier. This was accomplished via multispeed, auto-sensing NICs and hubs/switches.
