Internal Bus
The width of a data bus and the amount of data it can physically carry. It relates to how much data a computer can transfer within itself. A simple way of thinking of it is like a motorway. The more lanes there are on the motorway, the more cars can travel on it. A bus in a computer consists of lines of data being transferred around, so the more that can be carried, the faster your computer will go.

For intercity travel there is an excellent rail network. Within large cities use public transport (metro and/or bus). To get to remote places use bus or car. Ask about family reductions and the like.
Data bus moves data inside your computer. Normal cable moves data external. Data buses are parallel and most network media is serial. Some media is also analog where as the data bus passes data digitally. There are many differences but to be more specific would depend on which 'normal cable' you are referring too.
