Answer:
Evaluate and compare free and commercial versions of the antivirus software provided at the link above. Based on the information you learned in this Unit, what differences, if any, are significant enough to warrant considering paying for the software versus using the free version (for a typical home user, if the specific annual costs were not a major consideration)? What is “missing” from the personal/home/base level subscription that you might want?
Explanation:
Answer:
A) 2.56 ms
B) 128 μs
Explanation:
Time for Bus cycles = 500 ns
Transfer of bus control = 250 ns
I/0 device data transfer rate = 50 KB/s
Data are transferred at : 1 byte at a time
A) Determine how long the device tie up the bus when transferring a block of 128 bytes
Block size to be transferred = 128 bytes
Bandwidth = 50 KB/s
data transfer = (Block size ) / ( Bandwidth)
= ( 128 * 8 ) / ( 50 * 10^3 * 8 )
= ( 1024 ) / ( 50 * 10^3 * 8 )
= 2.56 ms
To determine the actual transfer time we have to add up the transfer time for the bus control in both directions :
2.56 ms + 500 ns = 2.56 ms. this is because 500 ns is not a significant value
B) cycle stealing mode
In this mode each byte is transferred at a time and The total transfer time needed for the bus control in both directions will be double the total time i.e 2 * 500 ns = 1000 ns. because additional control time of 250 ns is required at both ends
since 1 byte is transferred at a time , 1 byte will be transferred in 1 μs
128 bytes = 128 * 1 μs = 128 μs
Answer:
The correct option for the given question is option(B) i.e dot operator
Explanation:
Structure are collection of different datatypes member element .
Let us consider the example of structure
Struct test
{
int age ;
char name[45];
};
Here test is an "structure" which member is age of "integer" type and name of "String" type.if we have to access the member of structure,firstly we create structure variable name then after that we use dot operator which is also known as member access operator that access the members of structure.
struct test op;// structure variable name
op.age=12; // access the member age
For example
Following is the code in c language :
#include <stdio.h> // header file
struct test // structure declaration
{
int age ;
char name[45];
};
int main() // main function
{
struct test op;// structure variable name
op.age=12; // access the member age
printf("%d",op.age);
return 0;
}
Output:12
so correct answer is "dot operator"
In the above scenario, The way to solve the problem is to would contact tech support.
<h3>Whom would you contact first, and why?</h3>
I would also contact the number that is saved on my student ID for help as they will known about such problems.
The resources available to still read my detailed notes that I wrote, that tells the step by step way to quick fix it or contact the instructor to let them know of the current situation.
Therefore, In the above scenario, The way to solve the problem is to would contact tech support.
