<u>The first tools that analyzed and extracted data from floppy disks and hard disks were MS-DOS tools for </u><u>IBM</u><u> PC file systems</u>. A file system is a structured representation of data and a set of metadata describing this data. The file system of the IBM supports stream input/output and storage management, providing a structure over all information stored in the system. A floppy disk consists of a thin plastic disk coated with magnetic material (it was designed by IBM in the early 1970s). A hard disk is fixed on the system unit. It is made up of several circular disks called platters. MS-DOS (Microsoft Disk Operating System) is a licensed operating system for use on microcomputers from various manufacturers.
Answer:
count_p = 0
count_n = 0
total = 0
while True:
number = int(input("Enter an integer, the input ends if it is 0: "))
if number == 0:
break
else:
total += number
if number > 0:
count_p += 1
elif number < 0:
count_n += 1
print("The number of positives is: " + str(count_p))
print("The number of negatives is: " + str(count_n))
print("The total is: " + str(total))
print("The average is: " + str(total / (count_p + count_n)))
Explanation:
Initialize the variables, count_p represens the number of positives, count_n represents the number of negatives, and total represents the total of the numbers
Create a while loop iterates until the user enters 0. If the number is not 0, then add it to the total. If the number is greater than 0, increase count_p by 1. If the number is smaller than 0, increase count_n by 1.
When the loop is done, print the count_p, count_n, total, and average
Answer:
Each variable is named so it is clear which variable is being used at any time. It is important to use meaningful names for variables: ... The name given to each variable is up to the programmer, but ideally a variable name should have meaning, ie it should reflect the value that it is holding.
Variables make code more than a static set of instructions. They allow logic to occur, enabling developers to measure time, analyze data, and customize the program to the user. Variables are so important to the code that they deserve a good name that accurately describes their purpose
Explanation:
An information system is crucial to the success of a business. Itemized below are five benefits of operating an information system in a business.
<h3>What are the benefits of an Information System?</h3>
