Study Notes
Operating System Fundamentals
- The primary purpose of an operating system is to manage computer hardware resources and provide common services to computer programs.
Kernel Functionality
- The main function of the kernel in an operating system is to manage hardware resources, such as CPU, memory, and storage, and allocate them to running programs.
Memory Management
- The primary goal of memory management in an operating system is to efficiently allocate and deallocate memory space for running programs, while preventing conflicts and crashes.
Process and Thread
- A process is an independent unit of execution that runs in its own memory space, while a thread is a single flow of execution within a process that shares memory space with other threads.
- The key difference between a process and a thread is the memory space they occupy: processes have their own memory space, while threads share it with other threads.
Multi-Threaded Approach
- The main advantage of using a multi-threaded approach in a program is that it allows for concurrent execution of multiple tasks, improving responsiveness, and overall system performance, while also enhancing user experience.
