Why can’t the Linux kernel be developed in C?

The Linux kernel is developed using C language because: 1. C language is a high-level language, but closer to the bottom layer of hardware and operating system; 2. C language is widely used in system-level programming. And it has good portability and efficiency; 3. The kernel design is based on hardware platform minimization, which requires compact storage space and fast execution speed. C language can meet this requirement and is easier to maintain and write than assembly language.

The operating system of this tutorial: Linux5.18.14 system, Dell G3 computer.

The Linux kernel is the core of an operating system, responsible for managing computer hardware and software resources, providing interfaces to application programs, and performing necessary system tasks.

Due to its importance and complexity, C language is used to develop the Linux kernel instead of other high-level programming languages ​​for the following reasons:

1. C language is a high-level language, but closer to the underlying hardware and operating system. This means that C language has the ability to directly access the underlying resources of the operating system.

2. C language is widely used in system-level programming and has good portability and efficiency.

3. The kernel design is based on hardware platform minimization, which requires compact storage space and fast execution speed. C language can meet this requirement and is easier to maintain and write than assembly language.

Therefore, C language has become one of the mainstream kernel development languages. It is not accurate to say that C language cannot be used to develop the Linux kernel, because the Linux kernel is developed using C language.

The functions of the Linux kernel include:

1. Run and control all hardware devices on the computer

2. Manage processes (run applications)

3. Provides a user interface that allows users to interact with the operating system

4. Allocates and manages system resources such as memory, disk space, and network bandwidth

5. Provides security measures to protect Computers protected from unauthorized access, malware, and other threats
