Answer:
<u>720</u> possible PIN can be generated.
Explanation:
To calculate different number of orders of digits to create password and PIN, we calculate permutation.
Permutation is a term that means the number of methods or ways in which different numbers, alphabets, characters and objects can arranged or organized. To calculate the permutation following formula will be used:
nPr = n!/(n-r)!
there P is permutation, n is number of digits that need to be organize, r is the size of subset (Number of digits a password contains)
So in question we need to calculate
P=?
where
n= 10 (0-9 means total 10 digits)
r= 3 (PIN Consist of three digits)
So by using formula
10P3 = 10!/(10-3)!
=10!/7!
= 10x9x8x7!/7!
= 10x9x8
= 720
Answer:
It places the document in a buffer
Explanation:
Since the printer can only print a document at a time, the other document is going to be placed in a buffer.
The print buffer can be described as a location in memory that has the function of holding data that is going to be sent to a computers printer. A print job such as in this scenario may remain in the buffer because another document is to be printed first.
Sometimes a document could be put in the buffer because the computer is waiting for the printer to respond. This is just another reason why documents are placed in a buffer.
Answer:
c. recovery time objective
Explanation:
- Recovery time objective (RTO) is the maximum acceptable duration permitted between an unfortunate loss or failure and the restoration of normal operations and services.
- According to the RTO, the systems, applications or operations must be restored within a targeted time period after a disaster, to avoid unacceptable outcomes of the disruption.
-
So a business process must be recovered within this period of time.
-
It measures how much a failure affects the normal operations, applications and systems and RTO is measures in time units like seconds minutes hours or days.
- In simple words RTO refers to the time you need to restore system, applications and data.
- For instance a 2-hour RTO refers to restore and get operations or services back to running within 2 hours of the service failure or outrage.
A vocational school can also be called all of the following except a certification school.
The naming scheme that identifies the rows in a worksheet is B. 1, 2, 3.
Rows are horizontal, and they are identified by numbers in an Excel worksheet. On the other hand, columns are vertical, and they are identified by letters in the same Excel worksheet.
