Lesson: ASCII Code

ASCII Code is a universal standard utilized in computing. The acronym ASCII means American Standard Code for Information Interchange. When you press a keyboard key, an interrupt signal is sent to the computer’s processor, which prioritizes your action and memorizes the sequence of each keystroke as a preference. The position of alphanumeric characters is predetermined by ASCII. With each keystroke a byte of memory is devoured.  (Count eight bits [0,1] to a byte.) When you type ‘shift A’, it translates to 01000001 and ‘lowercase a’ is 0110001. These zero and one sequences are the way your computer understands your preferences.
