Today we talk about how Windows is started, because Linux is also a system, you only know how to start Windows, Linux startup will be solved.

Most people have the impression that when the computer starts, Windows is started first. But if we are careful, we can observe that in the start of the computer for a few seconds, the screen is displayed a series of images, commonly known as the "Start interface." The icon for Windows is not displayed until later.

For the "Start screen", we can not, because different computers, this part of the information is not the same.

Why is it?

Because it's about the hardware of the computer. In fact, it is the computer's motherboard (mother board) that shows the "Start Screen".

Motherboard is the main part of the computer, because it is the motherboard so that our processor can run, the hard disk can be read, the disc can be played. Motherboard (English is motherboard, mainboard, abbreviation Mobo) also known as the main board, system board, logic board, motherboard, backplane, etc., is a complex electronic system such as the center of the computer or the main circuit board. As shown below:

So, when the computer starts, the following two things happen in sequence:


    1. "Start Screen"

    2. Startup of Windows


Only when Windows starts smoothly can we use a variety of applications: browsers, drawing software, games, music players, and so on.


So why must you start Windows first? Why are the programs we use, such as drawing software, not available after the launch screen?


Because, your computer needs a "big butler" software, like the orchestra commander in chief, need to command the performance of each musician. This "Big butler" software needs to manage the memory of your computer and allocate the memory reasonably to each software. It acts as a "bridge" between the hardware (memory, graphics card, optical drive, etc.) and various software that connect the computer.


This mission sounds noble and sacred, isn't it?


This "Big Butler" software is the operating system, referred to as OS, is the operating system of the first letter (operating is the meaning of English "operation", system is the meaning of English "systems"). After the course, we often use the OS as the abbreviation to refer to the operating system, please remember.


And our Windows is an operating system.


So if we summarize, the computer will perform the task in the following order:


    1. Start interface

    2. Startup of the operating system (for example, Windows)

    3. Startup of other programs (or software)


Here, we all know how Windows started, there are children's shoes said, small series you are not talking about Linux, do not worry, next time we say Linux how to start.
