Give your comments and if you feel to add any other topic add it in comments section, we can include it for our discussion.
Embedded System Basics 
Nice blog. 🙂
1. Where enums are stored?
2. What made .bss section to come into acceptance ?
1.Where enums are stored?
enums doesn’t occupy any storage space, they are datatypes link char, int…
2. What made .bss section to come into acceptance ?
In C statically-allocated variables without an explicit initializer are initialized to zero (for arithmetic types) or a null pointer (for pointer types). Implementations of C typically represent zero values and null pointer values using a bit pattern consisting solely of zero-valued bits. Hence, the bss section typically includes all uninitialized variables declared at the file level (i.e., outside of any function) as well as uninitialized local variables declared with the static keyword. An implementation may also assign statically-allocated variables initialized with a value consisting solely of zero-valued bits to the bss section

Excellent Job …….Very helpful . Thanks….
