  1. Consider the following memory Architecture of a Machine in the following Table

Virtual Address

54 bits

Page size

16K bytes

PTE size

4 bytes

Assume that there are 8 bits reserved for the Os functions(protection,valid, modified,and Hit/Miss-all overhead bits) other than required by the hardware translation algorithm.Assume 1 application exist in the system and maximum physical memory is devoted to the process,How much physical space( in bytes), is there for the application data and code ?

  1. 2^26 byte

  2. 2^40 bytes

  3. 2^38- 2^26 bytes

  4. 2^40 - 2^38 bytes
