Shell是用户与操作系统交互的接口,负责接收并解释用户输入的命令;Kernel是操作系统的核心,负责管理硬件资源、进程调度等底层功能。 1. **Shell的作用**: - Shell(外壳)提供用户访问操作系统的途径,例如命令行界面(如Bash、CMD)或图形界面(如GUI)。 - 它不直接操作硬件,而是将用户指令转换为内核能理解的请求
The operating system kernel is the core component of an operating system that directly interacts with the hardware, managing memory, disk storage, and low-level networking. It provides an abstracted interface for the rest of the operating system, allowing it to read and write files and communicate...

Multiple Operating Systems refers to the practice of having more than one operating system within a single environment, allowing users to run different OSes on the same device using tools like emulators and virtual machines. AI generated definition based on: IT Manager's Handbook (Third Edition),...
Monolithic Kernel: In a monolithic kernel, the operating system behaves like a single program within a single domain where different parts (e.g., device drivers and memory management) are closely knit. Microkernel:A microkernel is a much simpler alternative that possesses only the basic services ...

当一个进程需要使用内核的服务,它其实是引用了操作系统接口中的一个函数调用。这样一个函数叫做系统调用(system call)。系统调用进入了内核;内核执行服务并返回。因此一个进程在用户空间(user space)和内核空间(kernel)之间轮流执行。 内核使用CPU的硬件保护机制来确保每个进程在用户空间执行时只能访问它自己的内存。内核...
用户模式,内核模式与系统调用/User mode, kernel mode and system call 强力的隔离需要在应用程序与操作系统之间设置一个硬边界。如果应用程序犯错了,我们不希望操作系统也跟着崩溃。相反,操作系统应该能够清理掉失败的应用程序然后运行其他应用程序。应用程序不可以修改(甚至读取)操作系统的数据结构以及指令,也不能访问其...
Before you begin setting up a dual boot Windows 10-Debian Linux system, you’ll need to know how to “image” bootable installation media, change the boot order on your PC, and allocate an empty internal storage partition (this last item is optional, as the Debian installer includes a sub...
