A normal computer: It includes devices from tiny pacemakers, to the much larger servers that host your websites and participate in the stock market. A supercomputer: These are built to do a certain task that requires something done really, really fast. They’re heavy-duty things that have a ton of RAM, processors, and all sorts of awesome, up-to-date tech. However, to do everyday tasks, or even some very demanding ones, you don’t need a supercomputer.
