How does a flash drive/pen drive store data?
Computer cannot understand analog signal, analog data refers to physical data like voice, radio signal, etc. We humans understand analog data but computers only understand digital data. To understand simple digital data , it has only two states as 0 or 1. Basically it corresponds to either ON state ie. 1 or OFF state ie. 0. Computers can’t be switched off entirely and hence OFF stage is represented by a low voltage (0) and ON stage is represented by a high voltage (1). Now humans have devised various techniques to interpret the data into digital form, for example one of the various forms is ASCII (American Standard Code for Information Interchange). In ASCII, Capital " A " is stored as seven binary numbers: 1000001 while small “ a ” is stored as 1100001 Question mark “ ? ” is stored as 0111111 Number “ 7 ” as 0110111 left bracket “ [ ” as 01011011 ASCII is a code which is agree...
