              HARD DISK INFORMATION OF POST (power-on-self-test)               During the Power-On Self Test (POST) process, which occurs when a computer is starting up, you can usually access information about your hard disk by entering the system's BIOS or UEFI settings. This is typically done by pressing a specific key (like F2, F12, Delete, or Esc) as the computer boots up. Within the BIOS or UEFI settings, you can navigate to the hardware or storage section to find details about your hard disk, such as its model, capacity, and connection status. HDD and SSD drives: drive types and interfaces comparison   There are two types of drives: HDD (hard disk drive) and SSD (solid-state drive). HDD HDDs are installed in most PCs and laptops. There are several aluminum plates inside the drive. Reading and writing operations are performed due to rotation of the plates and the sensing head located at a few...

                                          CONCEPT OF BOOTING Booting Booting is basically the process of starting the computer. When the CPU is first switched on it has nothing inside the Memory. In order to start the Computer, load the Operating System into the Main Memory and then Computer is ready to take commands from the User. Learn the types of booting. What happens in the Process of Booting? Booting happens when you start the computer. This happens when we turned ON the power or the computer restarts. The system  BIOS  (Basic Input/Output System) makes the peripheral devices active. Further, it requires that the boot device loads the operating system into the main memory. Boot Devices Booting can be done either through hardware (pressing the start button) or by giving software commands. Therefore, a boot device is a device that loads the oper...

1. WINDOWS OS   The Windows operating system is primarily developed using a combination of programming languages, with C and C++ being the most commonly used languages for its core components and system-level programming.

                                       VON NEUMANN ARCHITECTURE 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 ...
