What is Andriod
First of all, it is necessary to know that Android is not an mobile phone but an operating system developed by Google. The Android operating system is an operating system based on the Linux kernel, or it can also be said that it is a form or version of the Linux operating system that is customized by making Linux.
Learn more about Android Linux, which is an open source and free operating system, the main part of which is called Kernel, and the Android operating system has been created. Android is primarily designed with mobile devices in mind, so that we can do many things in our mobiles just like our computers.
The way we mostly use Windows in desktop or laptop computers, the same way Android comes for mobile and this is the most used in mobile. Android was initially launched only for mobile but as its market grew, Google started launching Android on other devices like TV, SmartWatch etc. The special thing about the Android operating system is that it is a free and open source operating system, that is, we do not have to pay separately for this, it comes with our mobile and anyone can see its source code.

Open-source is said to be software whose source code is open to all, that is, anyone whose source code can be seen and anyone can improve according to their own. A great example of this is the Xiaomi mobile phone in which you must have seen MIUI. MIUI is built by customizing Android's source code.
What is Linux kernel?
The kernel is the main part of the operating system. It is the part that interacts directly with the hardware to a great extent. It has a specific system software for each hardware called a driver.
In simple words, if we talk about our desktop, then there are many hardware components in it, like processors, RAM, GPU, in addition to this, many hardware components are connected in it, in a similar way, you can do all these things in your mobile too. Get to see Now we need a system that allows the application software to use the entire hardware resources correctly, and access all these resources to the software correctly.
Suppose you have to type a letter, then you will open the AMSword, then this software would like it to use my keyboard, now I have one to give this software access to the keyboard hardware There should be authority which can grant this permission to him. Now if there is a need to save the typed letter, then this software will also need permission to use the hard disk. If you want to take a hard copy from the printer, then this software also needs permission so that it can fully use the printer hardversion

This is the whole permission or the controlling authority, it is the colonel. Actually the kernel is a software that is a part of the operating system, which acts as a bridge between our hardware and software, and the hardware that the application software needs is a request to the kernel and the kernel makes that software Allows to use those hardware according to its request.

Why is Android so used?
Android is a great operating system. There are many reasons why it is great, as it is an open-source operating system based on linux kernal. Android has been very effective since the beginning, from above there is also a lot of developers for it, which keeps developing new apps for it.
One of the biggest reasons for Android OS to be popular is that mobile phones based on it are very cheap and bo also with very good and amazing features while its competitor Apple iPhone is very expensive and another reason for its popularity. It is that it has reached the market much earlier, while Windows Phone was launched much later.
But it is not at all that Android has its own merits. There are many flaws in this, as the hardware updates of every smartphone and customized according to the company, the latest updates do not reach all devices. Due to which the old devices go bad and waste over time.
