The Operating system monitor uses 32000 Bytes. Three users are using an editor. The editor is shared and uses 40000 Bytes. User 1 is editing a 24000 Byte file. User 2 is editing a 16000 Byte file, user 3 is editing a 12000-byte file. Assume that a SEGMENTED memory allocation scheme is used and the loading is in the order Monitor, Editor, User 1, User2 User3. Be sure to relocate in the correct order.

1. Complete the memory allocation table above. Be sure to show all addresses.

2. Can internal fragmentation occur? Why or why not.

3. Find the physical flat addresses corresponding to the following logical addresses:

Relative address 10000 in editor ___________________________.

Relative Address 4000 in User 2 ___________________________.

4. Find the program name and Relative address for the following physical flat addresses.

80000 Program ________________ Rel. Address _________________.

15000 Program ________________ Rel. Address _________________.

125000 Program ________________ Rel. Address _________________.

5. Give the values in the Base and Limit registers for:

Editor: Base ___________________ Limit ________________,

User 3: Base __________________ Limit ________________.
