Boolean algebra is the absolute mathematical foundation of all digital electronics and computer systems. Developed by mathematician George Boole in the mid-19th century, it's a branch of algebra where the variables can only have one of two possible values: TRUE or FALSE, often represented as 1 or 0. This binary nature makes it perfectly suited for representing the state of electronic circuits: a 1 can represent a high voltage (e.g., 5V), and a 0 can represent a low voltage (e.g., 0V). Unlike regular algebra which deals with numbers, Boolean algebra deals with logical operations. The three basic operations are: AND: Output is 1 only if all inputs are 1. (A ∧ B) OR: Output is 1 if at least one input is 1. (A ∨ B) NOT:* Output is the inverse of the input. If input is 1, output is 0. (¬A)These simple operations, when combined, allow us to design the complex logic circuits that form the backbone of everything from a simple calculator to a supercomputer.

In Palampur (as described in economics textbooks), non-farming activities include: - Dairy farming (milk collection, selling) - Small-scale manufacturing (carpentry, handicrafts) - Shopkeeping (general stores, cloth merchants) - Transport services (rickshaws, trucks, tongas) These provide income beyond agriculture.
