I was doing a Windows Update on my computer and an update came up under the 'Optional Hardware Updates' showing that there is an update for my Network Bus Enumerator - can someone tell me what this is and is it important for me to have this updated to the latest version?
Ok, a bus (in simple terms), carries data from one place to the next, typically a very short distance and no, they don't roam free within your computer. Dependant on the piece of Kit, there's usually 8 buses per journey.
Without any buses, your laptop wouldn't work. Provided it is a Microsoft update, brought to you via the Windows Update program, you may aswell update.
