Answer:
3) A Single linked list is a sequence of elements in which every element has link to its next element in the sequence.
DATA LINK
DATA stores actual value , LINK stores address of next node
As per information given in question, letters at the even addresses are items in linked list and the odd addresses will be used as links.
Even Address Odd Address
12 (Stores 't') 13 (Used as link)
14 (Stores 'm') 15 (Used as link)
16 (Stores 'a') 17 (Used as link)
18 (Stores 'r') 19 (Used as link)
20 (Stores 's') 21 (Used as link)
Numbers represented by circle are addresses of respective nodes. Here Front or Head has address 16. Which represents the Head Node.
Following image represents the word "smart" with respective nodes and their addressing.
Numbers represented by circle are addresses of respective nodes.
The head pointer is: 20
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
Answer:
The answer is A. Second Half of the month.
Explanation:
If Im reffering right to the source. So If you doing Chapter 3 Comp. Science. Than this is right.
The data type must be the same for each item in the array.
Answer:
Following are the definition of function
double averager (const double &x) // function definition
{
static double z = 0.0; // variable declaration
static size_t c = 0;
c=c+1; // increment of c by 1
z =z+ x; // adding value
return z /c ; // return average
}
Explanation:
Following are the description of statement
- Create a function averager of double type that holds a parameter "x" of the double type .
- In this function we declared a variable "z" of a static double type that value is initialized by 0.
- The static variable is used to retain value.
- Declared a variable "c" of size_t type that holds a value 0 .
- After that increment the value of c by 1 .
- adding the value of "z" variable to the "x" and storing the result into the z variable.
- Finally return the average value
