Errors

In computer jargon, an error is referred to as a bug . In case you are interested in the origin of this word, the story goes that when operating the first large-scale digital computer, called the Mark I, an error was traced to a moth that had found its way into the hardware. Incidentally, the Mark I (circa 1944) had 750,000 parts, was 51 feet long, and weighed over 5 tons. How about putting that on your desktop? It also executed about one instruction every 6 seconds, as compared to over 200 million instructions per second for a Pentium!

Errors can be grouped into three types based on when they occur — design time, compile time, or runtime.
