The next context of signaling takes special circuits and logical gates, and combines them to provide new processing power for our computer. The computer needs to keep data and lots of it. So we need to design a way of saving and retrieving data. This must work so the data is kept unchanged, unless we specify that the data is to be changed (written to) by signaling with a special signal.
This context is circuits to hold data (relatively indefinitely) and allow access to the data in the computer. This signaling is developed from logical gates. It is also used on a larger scale than the circuits for logical comparisons or the mathematical processes. Most logical comparisons and all mathematical processes are done in the Arithmetic Logic Unit (ALU) while the data we are saving is spread quite widely on chip-sets and in various parts and peripherals that contain memory of their own. Variations of this context include memory, caches, and registers that each hold data with different kinds of accessibility to the processes of the computer.
