[0:04]keyboard characters conversion to its binary equivalent. This will be our topic. And there's a question here. When the keyboard letter or character is tapped by humans, then how do a computer machine can able to understand and print it on its screen? As illustrated here, every time a letter is tapped on a keyboard as input, it then directly display on the computer screen, the letter H, the letter E, the letter L and so on and so forth. That serves as input from the keyboard and output in the computer screen. Easy may it seem, but that is not really how direct and simple the computer works. You will see here the series of letters H, E, L, L, and O for the word hello. Every time a human user typed a keyboard character or letter like H, the computer needs to convert it first to its own native language called machine language or sometimes known as binary numbers, numbers that are combinations of 0s and 1s, sometimes called as switches. A switch 0 means OFF, and a switch 1 is ON. A complex combinations, and yet is native and simple for every computer machines. So if we type letter H, then it will be converted by the computer into its own language, binary 0s or 1s to understand it and it will use another conversion or method so that for us humans can understand. How? Through the ASCII TABLE, specifically hexadecimal, decimal, character, and so on and so forth. So, as we go on with this topic, we will do computations or number conversions so that we will truly understand how computers take our human keyword characters as input, then fastly do some conversion as if it is magic, and display it on screen so that we all humans can understand. Well, it is an understanding between machines and us humans, and yes, we can call it human and machine communication.
