What is the core of the operating system and why is it so important?

BingMag.com What is the core of the operating system and why is it so important?

If you are a little familiar with the concepts of phone or computer software, you are probably familiar with the term kernel or the core of the Linux operating system. Android is one of the operating systems that uses the Linux kernel. In fact, it's an integral part of Android smartphones, but what exactly is the core of the operating system and why is it so important? For the operating system belonging to the Unix-like family. But what about the kernel or kernel of the operating system? What role does this kernel play in computers and other gadgets? Here's how.

In very simple terms, the operating system kernel controls key components such as the processor, system memory, network, and so on. It is also responsible for managing all the processes and tasks that are running on the smartphone. This means that when you open an application, the kernel is responsible for loading it into memory, creating the required processes, and running it. When the application needs memory, the operating system kernel allocates the required amount of memory.

A closer look at the operating system kernel

All operating systems Advanced people use something called a kernel. For example, we can mention Windows, macOS, iOS and of course Android. Among these operating systems, only Android uses the Linux kernel. Windows is based on a proprietary kernel, and Apple operating systems such as macOS and iOS also use a proprietary kernel called Darwin.

There are also a number of Unix-like cores from projects such as FreeBSD, OpenBSD and NetBSD. We should even mention a low-power kernel from Arm, called mbed OS.

The Linux kernel is a very complex piece of software with millions of lines of code. This kernel contains the necessary code to support various drivers as well as various architectures such as ARM, x86, RISC-V and others. When this kernel is prepared for a particular gadget (such as a phone), parts of its code are not used, but eventually, even if these parts are removed, you will still encounter very complex software.

Nuclear versus integrated core

Since Linux is based on an integrated kernel, you need to find a way to Enable and disable different parts of the kernel depending on user needs. This can be done during compilation by a system that allows the kernel to be set up and configured. Some configurations do more than just enable or disable a specific partition; in fact, they can change the behavior of the kernel as well. This feature is very important when developing and changing the hardware features of smartphones.

How does Android use Linux?

In appearance, Android is a good launcher that runs various applications and games. But behind the scenes of this user interface are several complex systems and frameworks. Applications must use the libraries and frameworks available on Android to perform tasks such as sending notifications, location access, fonts, SSL, and more. contract. As we said, this kernel, in addition to process management, contains code for all the different chipset architectures and hardware drivers. Examples include drivers for cameras, Bluetooth, WiFi, flash memory, USB, and audio.

How do phone makers change the core of the operating system?

Depending on the range The vast range of Android phones, the core of the operating system in each of these phones are somewhat different from each other. Mobile phone manufacturers need to work with chipmakers to get the core of the operating system ready for the best possible handsets. As a result, most of the time, some of the core kernel features are discarded and new drivers are added instead.

In this context, we can refer to how CPU cores are used. As you probably know, not all processor cores perform the same function, and some are used for heavy-duty tasks, while others that are low-power perform light-duty tasks. But in the meantime, smartphone makers can manipulate the core parameters of the operating system to provide better performance, for example, in exchange for more power consumption, or not use all the chip power to increase battery life.

However, the companies in question sometimes make the wrong decisions. Some of them greatly reduce the chip's power to increase battery life, which is protested by users. For example, the OnePlus 9 Pro does not use all of its chip power to increase battery life, and in recent years some companies have faced a lot of margins due to the manipulation of CPU performance to benchmark fraud.

Android and The Future of Using the Linux Core

One of the downsides of Linux success is the speed with which it can change. That's why there are special versions of the Linux kernel that have been supported for many years. Using these cores, Android prepares new cores called ACKs, which include dedicated sections of the operating system.

With Android 11, the process of integrating the core Android core and removing specific parts of the chip began. By doing this, handset makers no longer have to touch the core for different handsets, which makes their software preparation process easier. A number of Android 12-based handsets take advantage of this feature.

Thanks to this approach, Google can more easily update the Android kernel for different companies, which leads to increased security. On the other hand, we should mention the potential of this approach to increase the number of years that the phones in question receive updates.
