Assuming that the speed of the response is very important, but efficient use of memory is not as important, is an array or linked list more appropriate to use and why?
Please upvote if you are able to understand this and if there is any query do mention it in the comment section.
An array is more appropriate to use. As when it comes to accessing, an array can be accessed more easily and at a faster rate if compared with a linked list. As effiecient use of memory is not important, then speed can be achieved using an array.

1. Which implementation would you use to implement very dense polynomials of degree up to 100. (Array/Linked List) 2. Which implementation would you use on a stack that requires frequent operations of push and pop and whose size is guaranteed to stay below 50. (Array/Linked List)
Consider a method called insertElement(string element, int position) in an array-based list data structure. The purpose of this method is to insert an element (of type string) in the array at the given position within the array. This methods works fine for small array-based lists, but is very inefficient for large lists. Briefly explain why the same function is more efficient when implemented using a singly linked list.
Which of the following versions of the polynomial class implementation provides the most space efficient representation for polynomials with a large degree and very few terms, for example: 10x+ x200. Recall that the degree of the polynomial is the largest exponent of the term with a non-zero coefficient. SELECT THE SINGLE BEST ANSWER A static array-based implementation, where only the coefficients are stored in the array, and the exponent of each term is the index of the coefficient in the...
For the efficient memory management and to avoid errors modern systems uses secondary memory as a part of the main memory known as a virtual memory. When a computer system is running serval programs at the same time, the main memory often becomes exhausted. In such circumstances instead of closing some programs the operating system use the secondary memory as part of the main memory to store some data. In short virtual memory is an elegant interaction of hardware exceptions,...
PROBLEM TWO Because memory compaction is time consuming, the operating system designer must be clever in deciding how to assign processes to memory (how to plug the holes). When it is time to load or swap a process into main memory, and if there is more than one free block of memory of sufficient size, en the operating system must decide which free block to allocate (Don't worry... most stuffs will be discussed in chapter four of this course :))....
Caches are important to providing a high-performance memory hierarchy to processors. Below is a list of 32-bit memory address references, given as word addresses. 3, 180, 43, 2, 191, 88, 190, 14, 181, 44, 186, 253 For each of these references, identify the binary address, the tag, and the index given a direct-mapped cache with two-word blocks and a total size of 8 blocks. Also list if each reference is a hit or a miss, assuming the cache is initially...
Why are arrays important? Can you describe a situation during the design of a script where an array can be helpful? When would arrays be more appropriate to use than a database? What situations would a database be more appropriate to use than an array? Do arrays have any advantages over using a database?
Caches are important to providing a high-performance memory hierarchy to processors. Below is a list of memory address references, given as word addresses (in decimal, the byte-offset bits have been excluded from addresses). 1, 4, 8, 5, 20, 17, 4, 56, 9, 10, 43, 5, 6, 9, 17 For each of these references, identify the binary address, the tag, and the index given a direct-mapped cache with two-word blocks (two words per block) and a total size of 8 blocks....
5.2 Caches are important to providing a high-performance memory hierarchy to processors. Below is a list of 32-bit memory address references, given as word addresses. 3, 180, 43, 2, 191, 88, 190, 14, 181, 44, 186, 253 5.2.6 The formula shown in Section 5.3 shows the typical method to index a direct-mapped cache, specifically (Block address) modulo (Number of blocks in the cache). Assuming a 32-bit address and 1024 blocks in the cache, consider a diff erent
a. Tonda is testing a new lawnmower model that should be very fuel-efficient. They are still testing, but specifications from the engineers claim that the mower should run from between 5 hours to 8 hours on a single gallon of gas. What would be an appropriate distribution for modeling this and what would be the probability that the mower will last longer than 7 hours? b. Tonda has now completed some testing and found that most of the time, mowers...
