Getting Started with Linux Basics---learning experience

Nearly a week of basic Linux basics to learn, so I have a more comprehensive and overall understanding of Linux, through this week's study I compare Linux with Windows found that there are many special differences with Windows,linux to go to Windows, It also has a certain understanding of the instruction operation in Linux, and has learned some basic instruction operation.

A major feature of Linux is the multi-user, in Linux can create multiple users each user's permissions are different, all users of the storage is stored in the same physical hard disk, but the user and the user's storage information is also virtual isolation, that is, each user to their own resources (for example: files, Device) has specific permissions, the shell command can be quickly switch users this is very convenient compared to Windows. Linux has a modular design, our interaction with the Linux kernel is done through the shell command, in Linux I think the most characteristic is to put all the things files, feel that this is a great advantage, If you need to add special peripherals or hardware just need to put their corresponding file system into Linux can and Linux will be all the files of the modular after the more convenient to manage changes to the system is more free to add or remove some features only need to add or delete the corresponding file system can be 。 The management of Linux for all system files is implemented by the directory tree, which is different from the partition management of Windows, in Linux when we open a new program, the file system of the program will be mounted to the directory tree.

Linux uses a single-core modular design, I want to know how to communicate between modules and modules in Linux, if the core module communication efficiency is not high for the whole system is fatal, in Linux a module A is how to invoke another module B function? How does module a pass the information to module B?
