Answer: Resolution
Explanation: The total number of pixels that can be displayed on the screen at a time is called the resolution of the screen. This resolution is normally described in the pair of numbers, such as 2560 x 1440. This means, the computer screen is 2560 pixels wide and 1440 pixels tall.
Answer:
C. FIFO
Explanation:
The first-in, first-out (FIFO) page replacement algorithm is a low-overhead algorithm that requires work on the part of the operating system. On a page fault, the frame that has been in memory the longest is replaced.
Using FIFO algorithm implies that
a page which was brought into memory first will be removed first since variable was initialized very early. it is in the set of first in pages that will be removed.
It is the simplest page replacement algorithm. The operating system keeps track of all pages in the memory in a queue, the oldest page is in the front of the queue. When a page needs to be replaced page in the front of the queue is selected for removal that is first in first out.
A memory page containing a heavily used variable that was initialized very early and is in constant use is removed, then the page replacement algorithm used is called First In First Out.
Answer:
double *prices=new double [256];
Explanation:
To allocate memory on heap we use new keyword.In the above statement an array name prices is declared and the memory allocated to it is on the heap memory.
First look at double * prices.It is a pointer this pointer is created on the stack memory which holds starting address of the array present on the heap memory of size 256..
Answer:
Fields are the components that provide structure for a table. In fact, you can't have a table without fields. ... Fields in a table store the same category of data in the same data type. For example, if you have a NAME field in a table of customers, the entries for this field are all customer names and are stored as text.
