: The output depends on current inputs and previous states, requiring "memory" (e.g., Flip-flops, Latches).

to store a single bit of memory. These circuits are the building blocks that allow a machine to do more than just switch—they allow it to remember and calculate. 3. The Brain: The Processor

Individual logic gates are of limited use. Their true power emerges when they are interconnected to perform useful functions. This chapter explores the next level of abstraction: . These are broadly categorized into two types: combinational and sequential.

, the most basic decision-makers in a computer. Built from microscopic switches called transistors, these gates take electrical signals (on as "1" or off as "0") and apply simple rules of logic: Only releases a signal if inputs are on. Releases a signal if at least one input is on. Flips the signal—if "on" comes in, "off" goes out. 2. The Skeleton: Digital Circuits When these gates are wired together, they form . A few gates combined can create an to do math or a

Translates the syntax tree into a generic, platform-independent language version for optimization. : The output depends on current inputs and

While there are many types of gates, most digital systems are built using seven basic types: the AND, OR, NOT, NAND, NOR, XOR, and XNOR gates. The AND gate outputs a 1 only if all its inputs are 1. The OR gate outputs a 1 if at least one input is 1. The NOT gate, or inverter, simply flips its input (1 becomes 0, and 0 becomes 1). The NAND gate is a combination of an AND gate followed by a NOT gate, producing the opposite output of an AND gate. Similarly, the NOR gate is an OR gate followed by a NOT gate. These gates are often represented by distinct schematic symbols and their behavior is formally described using a truth table, which lists all possible input combinations and their corresponding outputs.

Connects the digital core to human-operable hardware like keyboards, displays, networks, and storage drives. Summary of the Digital Abstraction Layers
