Answer:
- Create partitions on each hard disk drives.
- Mount the partition created on each hard drive so they are accessible by the the operating system.
- Format the partitions created with a filesystem recognized by Linux.
Explanation:
Having purchased the two new SCSI hard disk drives with the controller cards for each and installed them properly, before using them for data storage and retrieval he must first use the fdisk command to create one or more partitions on each of the hard disk drives then mount any partitions created on the two hard drives so that they are accessible by the operating system before then proceeding to format any partitions created with a valid filesystem recognized by Linux.
Answer:
The solution code is written in Python 3
- digits = input("Enter 9 digits: ")
-
- multiplier = 1
- total = 0
-
- for x in digits:
- total += int(x) * multiplier
- multiplier += 1
-
- checksum = total % 11
-
- if(checksum == 10):
- print(digits + "X")
- else:
- print(digits + str(checksum))
Explanation:
Firstly, use input function to get user input for 9 digits (Line 1)
Next we can use a for-loop to estimate the summation (d1 * 1 + d2 * 2 + d3 * 3 + d4 * 4 + d5 * 5+ d6 * 6 + d7 * 7 + d8 * 8 + d9 * 9) ( Line 6-8)
Then only apply % operator to get the remainder of total and get the checksum (Line 10)
Next create if and else statement to print the digits string joined with X if checksum is 10 else join digits string with checksum value (Line 12 -15)
