Answer:

Differences between arrays and linked list are as following:-

Arrays store elements in contiguous memory location while the linked list does not store elements at contiguous memory location it connects nodes at different memory location.
Array has index to directly access the elements there are no indexes in linked list to directly access the elements.
Linked list contains Nodes which contains the data and the address of the next Node while the array contains only the data in the block.
Traversal over the arrays is easy while the traversal over the linked list is difficult as compared to arrays.

1. Choose in each case that it affects which of the Information security requirements (confidentiality, integrity, availability)

just olya [345]

The cases that it affects which of the Information security requirements is explained below.

<h3>What are the Information security violations of the above cases?</h3>

Someone has copied your credit card and CVV number has violated the confidentiality as this is to be known only by the owner for if the cvv is known by another person who is not the owner, it may lead to theft of the owners' funds/money.

If someone sends a message “Please come at 10 AM”, the receiver receives “Please come at 10.” and the person did miss the appointment due to the misinformation, it violates the availability. If one is not understanding a message, it is better to clarify so as to know if one will be available,

If the attacker has deleted the installed copy of the Microsoft Office application from your laptop is integrity/confidentiality. One who has integrity will not attack another's' system.

I tend to use a playstation switch. It runs out of data very quickly though, even with the unlimited plan.

What is TLB for? Why TLB? Given the following number, what is theeffective memory access time?

vodomira [7]

Answer:

A lookaside buffer translation (TLB) is a memory cache that reduces the time it takes to access a user memory place. TLB includes the most lately used page table entries.

TLB is used to overcome the issue of sizes at the time of paging. Page Table Entry (PTE) is used for framing the memory ,but it uses two references one for finding the frame number and the other for the address specified by frame number.

<u>Formula for finding effective memory access time-</u>

Effective Memory Access Time = (TLB access_time+Memory Access Time)*hit ratio + (TLB access_time+2*Memory Access Time)*(miss ratio)

Given in question,

Hit ratio = 0.90

Memory Access Time = 150ns

TLB access time= 5ns

Effective Memory Access Time = (TLB access_time+Memory Access Time)*hit ratio + (TLB access_time+2*Memory Access Time)*(miss ratio)

=(5+150) * 0.90 + (5+2*150)*(1-0.90)

=155 * 0.90 + (305*0.1)

=139.5 + 30.5

= 170ns
