introduce the concept of memory. Their output depends not only on the current input but also on the history of past inputs, or the "state." This state is stored using a special circuit called a flip-flop . A flip-flop is a simple one-bit memory cell that can be built from a handful of logic gates. By combining combinational logic with flip-flops, we can build far more powerful circuits that can store data and move through a sequence of steps. These include registers (a bank of flip-flops for storing multi-bit values), counters (which cycle through a sequence of states), and more complex state machines. Sequential circuits are the fundamental building blocks of memory and control logic within a computer.

The underlying open and close their physical transistors, manipulating electrical charges to produce the final calculation. Conclusion

The processor operates in a continuous loop governed by the system clock:

The compiler breaks the raw text of the source code into a stream of meaningful units called tokens (such as keywords, variable names, and operators).

Act as digital switches. They select one out of several input lines and forward it to a single output line based on control signals.

The fundamental units of digital memory. A flip-flop (such as the D flip-flop or JK flip-flop) can store a single bit of data indefinitely as long as power is maintained.
