Address range which can be represented in 20 bit binary data.

Answer:

                                                   In Binary                                                       In hexadecimal

 

Minimum possible number   0000 0000 0000 0000 0000                              0000

Maximum possible number 1111 1111 1111 1111 1111                                         FFFF

In c any hexadecimal number statr with 0x 0r 0X

So, address range   will be 0x0000 to 0xFFFF

It is 1MB memory range.

Note.

2^10 = 1KB

2^20 = 1MB

2^30 = 1GB  

Where 10, 20, 30 are number of bit.
