At the lowest level, computers operate using electricity. Logic gates are the fundamental building blocks of digital systems. They take one or more binary inputs (0 or 1, representing low and high voltage) and produce a single binary output based on logical rules. : Outputs 1 only if all inputs are 1. OR Gate : Outputs 1 if at least one input is 1. NOT Gate : Inverts the input (1 becomes 0, 0 becomes 1).

Every second, a 3 GHz processor repeats this cycle 3 billion times:

Checks the tokens against the grammatical rules of the language and builds an Abstract Syntax Tree (AST). logic gates circuits processors compilers and computers pdf

When you connect multiple logic gates together, you create . These are divided into two main categories: combinational circuits and sequential circuits. Combinational Logic Circuits

The magic of computing lies in abstraction. A software developer does not need to think about individual transistors or logic gates when writing code. Conversely, an electrical engineer designing a logic circuit does not need to know what application software will run on it. At the lowest level, computers operate using electricity

RAM organizes millions/billions of memory cells into an array.

With just these three (plus NAND, NOR, XOR, etc.), you can build anything. : Outputs 1 only if all inputs are 1

Writing in assembly is tedious, error-prone, and not portable. Compilers allow:

Most modern computers follow the Von Neumann architecture framework, which relies on four main pillars: A Central Processing Unit (CPU).
