You'll need to clarify the question. Hardware-wise? Software-wise?<br />
<br />
In general, the PC upon bootup checks how much memory by checking for connectivity of all its memory slots. Those that have memory, it checks the capacity and type via the &quot;standard&quot; ID signals. Then it runs a quick test ( the memory countdown, if you have it enabled in BIOS) to make sure. Then the memoyr is assigned in sequence to the addresses...<br />
<br />
So before the O/S loads, the computer would know how much memory you do have. If that doesn't answer your question, you'll need to explain what you're looking for.<br />

memory

Hardware includes cell phones and other digital living devices, tablets, computers, servers, peripherals and components, printers and scanners, gaming consoles, networking hardware such as routers, hubs, switches and modems, storage devices and security equipment such as firewalls and other appliances.

Hardware

Components are those devices that are internal to a computer -- the PC boards, the central processor (CPU), the memory (RAM), disk and video controllers and so on.
