 What is tears on the computer?


 Today, working on computers is so easy to see children as experts. When you change your computer, after some time you see the operating system on the screen and you start your work. But do you have this question when you lie on your PC?

When we turn on a computer before we call the desktop, the user's friendly graphical user interface (GUI) appears on the screen, there are many things. So today we find that secret action is being done behind the computer

Computer hardware is powered When you press the Power button, the computer provides electricity to its components - motherboard, CPU, hard disk, solid state drive, graphics processor, and everything in the computer.

 The part of the power supply hardware is known as SMPS.


 Within a typical desktop PC, it looks like a box on the corner of the case, and it is connected to the AC power cord.

Load CPU, UEFI or BIOS Now when there is electricity, the CPU launched itself a small program, which is usually stored on the mother's chip.

  In the past, the PC is called a BIOS (Basic Input / Output System) some loads. But now on the advanced PC, CPU instead installs the UEFI (unified Extensible Firmware interface) firmware. This is the oldest alternative to the old-style BIOS. But, to make it more astray, some PC manufacturers still say as their UEFI software "BIOS".

BIOS Is Computer In Hindi? And how does this work?

UEFI or BIOS test and hardware initially Motherboard boos or UEFI firmware burden settings from any particular location - traditionally, a memory that is backed up by the CMOS battery. If you change some low-level settings in your BIOS or UEFI settings screen, it's stored on your custom settings.

CPU operates UEFI or BIOS, which tests your system's hardware and includes CPU. For example, if there is no rim in your computer, it will cross the boot process and show you an error. It is known as Post (Power on Self Test).

During this process you can see the PC Builder logo on your screen, and you'll press F10, F2 or other buttons to access your BIOS or UEFI settings screen here. However, now many advanced PC users are fast enough to ignore the user and they need to access their UEFI settings screen from the Windows boot option menu.


UEFI can do much to just start the hardware; it's actually a small operating system. For example, Intel CPU has an Intel Management Engine. It offers many features, including Intel's active management technology, which allows remote PC management to be allowed.


UEFI or BIOS handles your responsibility on boot device After testing and launching your hardware, you will be responsible for booting your computer to UEFI or BIOS.


To boot your operating system, find UEFI or BIOS searches for "boot device", it's usually a solid state drive for your computer's hard disk or solid state drive, but sometimes it's also CD, DVD D, USB drive or a network location may also be. .


You can create these boot devices from the BIOS setup screen.


 If you have a lot of boot devices, UEFI or BIOS tries to put them in your startup process. For example, if your system has the first boot device in the optical drive and you have inserted the bootable DVD into your computer's optical drive, then you can start the optical drive DVD on your hard drive. Will try to boot


Traditionally, the BIOS is looking at an MBR (master boot record), which is in the special boot sector at the start of a disk. The MBR code loads the rest of the operating system that is called "boot loader." The BIOS processes the boot loader, which takes from there and starts operating the original operating system - Windows or Linux.

The computer with UEFIs can still use this old-style MBG boot procedure to boot the operating system, but they usually use EIFI capable. They are not safe at the beginning of the disk, instead they are safe on distribution of EFI systems.


In any way, these two principles are the same: BIOS or UEFI finds a storage device on your system or in an MBR or by distributing EFI system so that it can see and run a small program.



 If there is no boot device, the boot-up process fails, and you will see such a wrong message on your display.


On the modern PC, the UEFI firmware is usually a safe boot
