What is a far pointer? Where we use it?

[chinmay.sahoo]

A far pointer is a four byte pointer that used to access the main memory of the system. It can access the code and data segment, just by modifying the offset you can modify the address.

Far pointer is a pointer variable. It is just like near pointer. But if we use large memory models, then we can use these far pointers. Because these far pointers occupy 4 bytes of memory.
