THe circled answered are not quite correct.
1. The RSA algorithm is a symmetric encryption algorithm. b. an asymmetric encryption algorithm. c a firewall. d. a directory verification algorithm for journaling file systems. e none of the above 2 A worm is a virus. b. a Trojan horse c a trap door d. a self-replicating program. e. none of the above The minimum number of frames that must be allocated to a process in a system that uses demand paging is: a. always one b. determined by the computer architecture c the same as the number of pages in the logical (virtual) address space of the process equal to the number of page frames into which memory has been divided none of the above 4 Assume we have a tree structured directory. If we express the location of a file in the tree starting from the current directory, this path is often referred to as a: a absolute path b locality of reference e relative path d. search path e none of the above 5 If thrashing is occurring in a demand paged computer system, one woul to see a lot of a internal fragmentation b external fragmentation s disk activity CPU utilization c none of the aboveExplanation / Answer
Answer 1. b. an asymmetric encryption algorithm
It is an asymmetric encryption algorithm, because it works on two different keys i.e. public key and private key.
Answer 2. d. self-replicating program
A worm is self-replicating malware progarm that duplicates itself to spread to uninfected computers.
Answer 3. b. determined by computer architecture
Answer 4. c. relative path
we use absolute path which begins with the root directory and relative path which is relative to the current working directory.
Answer 5. c. disk activity
Thrashing leads low CPU utilization, and see a lots of disk activities, because page is not found multiple times and swapping occurs again and again.
