Difference between Porting OS and Booting OS?
I am working with raspberry Pi, and loading the OS image file by using SD card into the board.
I thought that is porting process, then what is mean by the booting process.
I have asked this question by one of my client.

Please share it.....
 

The two terms have distinctly different meanings.

Porting is the process of modifying source code to allow it to execute properly on a different platform than the software was original written.

Therefore, porting an OS implies the process of modifying the OS source code to properly run on a different platform or device.

Booting an OS is the start up or reset process required to initially load and begin execution the OS.

Boot is a shorten version of the term "bootstrap."

Similar, vaguely interchangeable but different context.

There are many ways to Boot an OS, depending on the paths of ROM and subsequent paths or ports for subsequent delegating control of execution of initialization and boot code. It could start as embedded ROM in ARM or SPI flash in PC's , thus peripheral ports are initialized differently.

So Booting is a generalized descriptive verb of initialization sequence of the OS, where Porting is more descriptive verb which includes a list of physical paths compiled to execute each stage of boot process.
