Logic Gates, Circuits, Processors, Compilers and Computers (2021) by Jan Friso Groote, Rolf Morel, Julien Schmaltz, and Adam Watkins is a modern, holistic undergraduate textbook published by Springer Nature
These circuits rely on both current inputs and previous states, introducing memory into the system.
The Control Unit look at the address in the Program Counter and fetches the binary instruction from the system's main memory (RAM). logic gates circuits processors compilers and computers pdf
High-level programs (like web browsers or video games) compiled down to machine instructions that interact with the OS to do meaningful work for the user. Conclusion
At the deepest hardware level, a computer is an elaborate network of switches. Originally, these were electromagnetic relays (mechanical), then vacuum tubes (fragile glass), and finally, the – a solid-state semiconductor device. Conclusion At the deepest hardware level, a computer

Low-level software hardcoded into the motherboard that initializes the physical parts when the computer turns on.
A Central Processing Unit (CPU), or processor, is a massive collection of combinational and sequential circuits organized to execute instructions. It is the "brain" of the computer.
: These are known as universal gates. Engineers can build any other type of logic gate using exclusively NAND or exclusively NOR gates. This makes manufacturing microchips highly efficient, as factories can repeat the same basic gate structure billions of times on a single piece of silicon. 2. Scaling Up: Digital Circuits
These add "memory" to the mix. By feeding an output back into an input (latches and flip-flops), the computer can "remember" a previous state. 3. The Brain: The Processor (CPU)
