A digital computer represents all data using only two binary digits — 0 and 1. These two digits correspond directly to the two possible states of an electronic switch (OFF and ON). Groups of 0s and 1s are used to represent numbers, letters, and special characters.
PracticeAnalog signals are continuous and can take any value within a given range. Digital signals are discrete and use only specific values, typically represented by binary digits (0 and 1).
PracticeA truth table represents a Boolean function or digital logic circuit in table form. It shows how a logic circuit's output or Boolean expression responds to all the possible combinations of the inputs using logic '1' for true and logic '0' for false.
PracticeBoolean identities are mathematical expressions or equations that are always true, regardless of the values of the variables involved.
