Of the following, which is/are true about the process of swapping a page out of DRAM and into disk:You can select more than one
-
The Operating System chooses which page to move from DRAM to disk
-
The program whose page is getting swap from DRAM to disk was the program that triggered the fault.
-
The valid bit of the page that is moved from DRAM to disk is set to 1
-
The operation of swapping page will be faster if the page being replace has not been modified.
Homework Answers
Answer:
Following statements are true:
The Operating System chooses which page to move from DRAM to disk.
The program whose page is getting swap from DRAM to disk was the program that triggered the fault.
The operation of swapping page will be faster if the page being replace has not been modified.
Explanation:
The valid bit of the page that is moved from DRAM to disk is set to 1 is false because
Valid bit is an indication to say that page present in DRAM is
valid. If we bring page from disk to ram we set valid bit as
1
because the page currently is valid. When we move that page from
DRAM to disk we set it as 0 as it has become invalid now.
Please give thumbsup, if you like it. Thanks.
