1. What is the difference between a. and a. What is the significance of Boolean functions in hardware architectures? Boolean functions play a crucial role in hardware architectures as they provide a convenient way to describe and manipulate binary data. Binary signals form the hardware's core, representing information as either a high (1) or low (0) power state. Boolean functions, rooted in Boolean mathematics, provide a means to explain the inner workings of digital circuits. These functions demonstrate…
