A computer program is a group of instructions that performs a specific task when executed, or ran, by a computer.
so what sort of “tasks” do programs do?
Have you ever printed something onto a sheet paper? Read something on a computer screen? Used a microphone? Listened to sound through computer speakers? Printers, screens, microphones, speakers; those are all ‘devices’.
Most computer devices require programs to function properly. Without programs, we wouldn’t be able to use our computers.
