Answer:
we use the '!'operator to see whether some expression is false.
Answer:
MDF, IDFs
Explanation:
MDF or main distribution frame is a cable racking system in networking used to interconnect and manage information technology connecting cables from itself to multiple IDFs.
The IDF or intermediate distribution frame, on the other hand, are cable racks that holds or stacks networking devices together and connects it cables to a central MDF rack.
A scenario of this connection is IDFs mounted on various floors on a building and all connected to one MDF.
Answer:
When Microsoft switched to XML-based file formats in Office 2007, they added the 'x' to the file extensions to differentiate from the previous, incompatible formats such as dox to docx.
In other words. X is extended.
Answer:
Time taken to travel from one track to the next = 0.08ms
Initial track= 15 0
4 (15-4)*(0.08)= 0.88
40 (40-4)*(0.08)= 2.88
35 (40-35)*(0.08)= 0.4
11 (35-11)*(0.08)= 1.92
14 (14-11)*(0.08)= 0.24
7 (14-7)*(0.08)= 0.56
----------------------------------------------
Total seek time=0.88+2.88+0.4+1.92+0.24+0.56=6.88ms
Explanation:
We caculate the seek time for each request, and then add them together to find the total seek time. The final track number for the current request becomes the current track of next request, and this process is repeated till the last request is processed.
Answer:
A class is an good representation of the abstract data type as it is represented independently. For implementing a class, it is use to specify the interface for an abstract class.
Class is one of the type of abstract data type for the objects that whose behavior is basically define by the set of operations and values. It is known as abstract as, it provide an implementation independently.
When the class is using in an abstract data type, then it refers as hidden representation of the data. In this modern era, class is use for the implementation of the abstract data type.
