Half-adders sum two single bits. Full-adders include a carry-in bit to sum complex binary numbers.

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).

Which deliverable do you want next?

Breaks down the raw source code text into meaningful units called tokens (keywords, variable names, operators). Half-adders sum two single bits

: Stores both the data and the instructions currently being processed.

Processors only understand one thing: . This is a raw stream of binary numbers ( 00110101... ) unique to each specific CPU architecture (such as x86 or ARM). Logic gates are the fundamental building blocks of

These basic gates can be combined to create more complex gates, such as:

: Act as data selectors to forward one of multiple inputs to a single line.
