 The device driver is more like a driver framework, UART, IIC, SPI, SDIO, USB device/host, EMAC, MTD NAND etc. The developer can easily add low level driver and board configuration, then combined with the upper framework, he/she can use lots of features.
 
 The Component is a software concept upon RT-Thread kernel, for example a shell (finsh/msh shell), virtual file system (FAT, YAFFS, UFFS, ROM/RAM file system etc), TCP/IP protocol stack (lwIP), POSIX (thread) interface etc. One component must be a directory under RT-Thread/Components and one component can be descripted by a SConscript file (then be compiled and linked into the system).
 
-The Dyanmic Module, formerly named as User Applicaion (UA) is a dyanmic loaded module or library, it can be compiled standalone without Kernel. Each Dyanmic Module has its own object list to manage thread/semaphore/kernel object which was created or initialized inside this UA. More information about UA, please visit another [git repo](https://github.com/RT-Thread/rtthread-apps).

-The Cortex Microcontroller Software Interface Standard (CMSIS) provides a single standard across all 
-Cortex-Mx processor series vendors. It enables code re-use and code sharing across software projects 
-and reduces time-to-market for new embedded applications.
-
-CMSIS is released under the terms of the end user license agreement ("CMSIS END USER LICENCE AGREEMENT.pdf").
-Any user of the software package is bound to the terms and conditions of the end user license agreement.

-You will find the following sub-directories:
-
-Documentation           - Contains CMSIS documentation.
- 
-DSP_Lib                 - MDK project files, Examples and source files etc.. to build the 
-                          CMSIS DSP Software Library for Cortex-M0, Cortex-M3, Cortex-M4 processors.
-
-Include                 - CMSIS Core Support and CMSIS DSP Include Files.
-
-Lib                     - CMSIS DSP Libraries.
