• Partitioning- is typically the first step of preparing a newly manufactured disk, before any files or directories have been created 

Remember:

                       1KB = Thousand bytes = 1024 bytes

                       1MB = Million bytes = 1024 KB

                       1GB = Billion bytes = 1024 MB

                       1TB =Trillion bytes = 1024 GB

Examples: Original size/capacity = 40995 MB

P1 - 50% = 40995 x .50 = 20498
P2 - 25% = 40995 x .25 = 10249
P3 - 75% = 40995 x .75 = 30746

P1 - 25GB = 25 x 1024 = 25600

P2 - 41% = 40995 x 41 = 16808
