Computers are incredibly powerful machines, capable of performing amazing feats like playing
competitive chess, serving thousands of web pages, or making millions of complex calculations in less
than a few seconds. But deep down, computers are actually pretty dumb. Computers can only do exactly
what we humans tell them to do. W e tell computers how to behave using computer programs, which are
just sets of instructions for the computers to follow . Without programs, computers can’t do anything at
all!
