Those who gives instructions to the computers are known as programmers. Computer cannot understand language as we use to communicate with each other. Computer can understand only binary language(0 and 1). Binary code is very difficult to understand since it is only in form of 0 and 1. Computer is not smart enough to do task on its own, we need to provide instructions to perform task. We use programming languages to give those instructions to the computer.
