Explanation:
Data security is essential to protecting unwanted people from having access to ones data, malicious attack should also be prevented and unusual behavior should be monitored.
Data security has many facets such as threat nature, the nature of intruders, and cryptography. Furthermore, data integrity means that unauthorized users should not be able to modify any data without the owner's permission. Also, the statement that a common category of intruders are driven by determined attempts to make money; for example: bank programmers attempting to steal from the bank they work for is correct.
It should be no noted that rats gnawing backup tapes cannot prevent data loss. Therefore, the correct option is D
The importance of the 8 functions of an operating system
Answer:
Explanation:
Important functions of an operating System:
Security –
The operating system uses password protection to protect user data and similar other techniques. it also prevents unauthorized access to programs and user data.
Control over system performance –
Monitors overall system health to help improve performance. records the response time between service requests and system response to have a complete view of the system health. This can help improve performance by providing important information needed to troubleshoot problems.
Job accounting –
Operating system Keeps track of time and resources used by various tasks and users, this information can be used to track resource usage for a particular user or group of user.
Error detecting aids –
Operating system constantly monitors the system to detect errors and avoid the malfunctioning of computer system.
Coordination between other software and users –
Operating systems also coordinate and assign interpreters, compilers, assemblers and other software to the various users of the computer systems.
Memory Management –
The operating system manages the Primary Memory or Main Memory. Main memory is made up of a large array of bytes or words where each byte or word is assigned a certain address. Main memory is a fast storage and it can be accessed directly by the CPU. For a program to be executed, it should be first loaded in the main memory. An Operating System performs the following activities for memory management:
It keeps tracks of primary memory, i.e., which bytes of memory are used by which user program. The memory addresses that have already been allocated and the memory addresses of the memory that has not yet been used. In multi programming, the OS decides the order in which process are granted access to memory, and for how long. It Allocates the memory to a process when the process requests it and deallocates the memory when the process has terminated or is performing an I/O operation.
Processor Management –
In a multi programming environment, the OS decides the order in which processes have access to the processor, and how much processing time each process has. This function of OS is called process scheduling. An Operating System performs the following activities for processor management.
Keeps tracks of the status of processes. The program which perform this task is known as traffic controller. Allocates the CPU that is processor to a process. De-allocates processor when a process is no more required.
Device Management –
An OS manages device communication via their respective drivers. It performs the following activities for device management. Keeps tracks of all devices connected to system. designates a program responsible for every device known as the Input/Output controller. Decides which process gets access to a certain device and for how long. Allocates devices in an effective and efficient way. Deallocates devices when they are no longer required.
File Management –
A file system is organized into directories for efficient or easy navigation and usage. These directories may contain other directories and other files. An Operating System carries out the following file management activities. It keeps track of where information is stored, user access settings and status of every file and more… These facilities are collectively known as the file system.

Write a Python program square_root.py that asks a user for an integer n greater or equal to 1. The program should then print the square root of all the odd numbers between 1 and n (Including n if n is odd). Print the square roots rounded up with no more than two digits after the decimal point.
Answer:
import math
n = int(input("Enter n: "))
for number in range(1, n+1):
if number % 2 == 1:
print("{:.2f}".format(math.sqrt(number)), end=" ")
Explanation:
In order to calculate the square roots of the numbers, import math. Note that math.sqrt() calculates and gives the square root of the given number as a parameter
Ask the user to enter the n
Create a for loop that iterates from 1 to n+1 (Since n is included, you need to write n+1)
Inside the loop, check whether the number is odd or not using the if structure and modulo. If the number is odd, calculate its square root using the math.sqrt() and print the result with two digits after the decimal

It is common for people to name directories as dir1, dir2, and so on. When there are ten or more directories, the operating system displays them in dictionary order, as dir1, dir10, dir11, dir12, dir2, dir3, and so on. That is irritating, and it is easy to fix. Provide a comparator that compares strings that end in digit sequences in a way that makes sense to a human. First compare the part before the digit as strings, and then compare the numeric values of the digits.

Your dashboard should show the sum and average as two separate columns. If you use measure names as the column field, what should you use for the marks
Answer:
Hence the answer is a sum.
Explanation:
Here the statement shows that the dashboard should show the sum and average as two separate columns if we name measure names because the column field then for marks we'll use the sum. Since the sum displays the sum of the values of all the fields, which refers to the marks of the person.
Therefore the answer is a sum.
If we use measure names as the column field, we should use "the sum".
A set of cells that are support equipment on about a similar vertical line, is considered as a column.
Usually, the name of the user or a client represents a field column, while the total and sometimes even averaging columns in our dashboards or screen are different.When using a summation of total summary, perhaps the column field (title), as well as its amount and averaging marking, are indicated.The preceding reply is thus right.
