Commonly known as computer programs -these, are the instructions for the computer’s tasks.
Like paper programs, (which we get before the start of performances, like Concert Shows, a Graduation or Stage Plays.
Software are a way to communicate to the computer user, about the computer’s ongoing performances. Computer software, like paper programs could be considered the same idea in this instance. Much more detailed than paper programs, software contains all the necessary parts that make the whole show.
The "stage" is the CPU, Ram, Hard drive.
The public enjoys the performance through the computer display, the performers are the programs
themselves.
Because computers can execute muti-millions of instructions per second; millions+ of performers and performances have to be coordinated in a way that makes the computer run without declaring any software errors, glitches, bugs, or unwanted features.
