Turbo c compiler is based on Dos operating system which is based on 8085 microprocessors. In 8085 microprocessor actual physical address is represented in 20 bit. But there are not any pointers which can point 20 bit address. Considering simplicity of calculations, access to actual physical address, security etc. c has introduced three type of pointer i.e. near, far and huge pointer.
