It's possible for a program (or 'process' as its technically called) to do not just one task but several tasks simultaneously. Each of these tasks are called 'theads of execution' or 'threads' for short.
Of course, unless your system has several processors, this notion of several threads running simultaneously is an illusion because a single core processor can only do one thing at a time. The operating system creates this illusion by switching between the different theads according to certain rules but this generally happens so fast that the user of the program is unaware of it.
