They/you are asking the speaker to clarify what they just said.
Answer:
The answer to this question is given below in the explanation section.
Explanation:
The CPU is responsible for processing instruction. CPU instruction processing goes through three stages. Fetch, Decode, and Execute.
When the program runs, program code is copied from secondary storage into main memory. CPU's program counter set to the first instruction of the program stored in memory where the program starts executing.
When a program is being executed, it goes through fetch-decode-cycle. which repeats over and over again until reaching the STOP instruction.
The processor check which next instruction to be executed, then the processor fetches that instruction value from the memory location. once the instruction being fetched it gets decoded and executed. This instruction processing cycle repeating until the CPU finds a stop instruction.
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.
Answer:
The code to calculate the area of a circle is:
from math import pi
def circleArea(radius):
if radius > 0:
return pi * (radius ** 2)
else:
return None
if __name__ == '__main__':
radius = 5
print("Radius: {} Area: {}".format(radius,circleArea(radius)))
Explanation:
A detailed explanation of each line of code is given below.
#Define the number pi used to calculate the area
from math import pi
#We define a function that calculates the area of a circle
def circleArea(radius):
#Check if the radius is valid ( radius > 0) since there aren´t negative radius
if radius > 0:
#Compute the area formula for a circle 
return pi * (radius ** 2)
else:
#Return None if the radius is invalid
return None
#Run the function we´ve defined
if __name__ == '__main__':
#Define a radius
radius = 5
#Call the function and parse the radius through it, then print the result
print("Radius: {} Area: {}".format(radius,circleArea(radius)))
Answer:
The answer is "Option a, c, and d".
Explanation:
This command aims to define the argumentation from each entity of the file system like a disc, path, or link. It checks the usage of a measurement system, which is requested to collect the information from either the inode of the item, the description of the option as follows:
- In option a, It is used to identify the file type.
- In option c, This command is used to list all file types.
- In option d, This command is used to list all the current directories.
- In option b, It is used to describe a single entity directory.
