Answer:
D) can access main memory at the same time as the main CPU
Explanation:
DMA is short for Direct Memory Access, these controllers allow the device to transfer data directly to and from the memory modules without interfering with CPU processes. Therefore it can access main memory at the same time as the main CPU. Thus freeing up CPU processing power for other tasks while also retrieving the data necessary.
Answer:
Option (d) is the correct answer.
Explanation:
An Array is used to store multiple variables in the memory in the continuous memory allocation on which starting index value is starting from 0 and the last index value location is size-1.
In java programming language the array.length is used to tells the size of the array so when the user wants to get the value of the last element, he needs to print the value of (array.length-1) location so the correct statement for the java programming language is to print the last element in the array named ar is--
System.out.println(ar[ar.length-1]);
No option provides the above statement, so option d (None of these) is correct while the reason behind the other option is not correct is as follows--
- Option a will prints the size of the array.
- Option b also gives the error because length is an undeclared variable.
- Option c will give the error of array bound of an exception because it begs the value of the size+1 element of the array.
Answer: True
Explanation:
Yes, the given statement is true that the due to the very low feasibility the IT (Information technology) department are not aware of the hidden backlog that basically contain projects.
The feasibility is the main factor in the IT department as it helps to study whole objective of the project and then also uncover all the strength and weakness of the project so that we can easily go through the details to make the project more efficient and reliable.
Answer:
The benefits of SSDs over HDDs include:
Faster read/write speeds. SSDs can access large files quickly.
Quicker boot times and better performance. Because the drive does not need to spin up as an HDD would, it is more responsive and provides better load performance.
Durability. ...
Power consumption. ...
Quieter. ...
Size.
