The "POST" primarily focuses on checking essential hardware components such as the CPU (Central Processing Unit), RAM (Random Access Memory), motherboard, graphics card, keyboard, and other critical components. It ensures that these components are op
erational and that the computer can proceed to the next stage of the boot process, which involves loading the operating system.

The hard drive capacity check typically occurs later in the boot process when the BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface) is accessed. The BIOS/UEFI is responsible for initializing and configuring hardware components, and it often includes a component that identifies the attached storage devices, including hard drives, solid-state drives, and other storage media.

During the BIOS/UEFI initialization, the system may display a summary screen or provide access to a setup utility where you can view information about the connected storage devices, including their capacity, model, and other relevant details. This information is displayed as part of the system information and configuration options provided by the BIOS/UEFI.

The exact location and timing of the hard drive capacity check within the boot process can vary based on the specific motherboard, BIOS/UEFI version, and system configuration. Typically, it occurs after the POST but before the operating system is loaded.

The von Neumann architecture—also known as the von Neumann model or Princeton architecture—is a computer architecture based on a 1945 description by John von Neumann, and by others, in the First Draft of a Report on the EDVAC. The document describes a design architecture for an electronic digital computer with these components: A processing unit with both an arithmetic logic unit and processor registers A control unit that includes an instruction register and a program counter. Memory that stores data and instructions External mass storage Input and output mechanisms The term "von Neumann architecture" has evolved to refer to any stored-program computer in which an instruction fetch and a data operation cannot occur at the same time (since they share a common bus). This is referred to as the von Neumann bottleneck, which often limits the performance of the corresponding system. The design of a von Neumann architecture machine is simpler than in a Harvard architecture machine—...
