Communication between the components of Linux Kernel | Case Study | 2016

In the Linux kernel structure, the I/O component, Memory management component, and Process management component communicate with each other through various mechanisms, including function calls, data structures, and system calls.

1. I/O component: The I/O component handles input and output operations, including reading and writing to files, network communication, and interacting with hardware devices. It communicates with the Memory management and Process management components using system calls and data structures. For example, when a process needs to read data from a file, it makes a system call to the I/O component, which then interacts with the Memory management component to retrieve the data from memory and return it to the requesting process.

2. Memory management component: The Memory management component manages the allocation and deallocation of system memory. It communicates with the I/O and Process management components through data structures and system calls. For example, when a process needs to allocate memory for a new data structure, it makes a system call to the Memory management component, which then allocates the required memory and returns a pointer to the requesting process.

3. Process management component: The Process management component manages the creation, scheduling, and termination of processes in the system. It communicates with the I/O and Memory management components using system calls and data structures. For example, when a process needs to create a new process, it makes a system call to the Process management component, which then allocates memory for the new process, initializes its data structures, and schedules it for execution.
