To Create A Partition

What is disk partitioning?
Disk Partitioning is the creation of one or more regions on a  hard disk or other secondary storage, so that an operating system  can manage information in each region separately.

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

Remember:

                     1 KB      = thousand bytes
                     1 MB     = million bytes
                     1 GB      = billion bytes
                     1 TB       = trillion bytes

Remember:

                     1 KB      = 1024 bytes
                     1 MB     = 1024 KB
                     1 GB      = 1024 MB
                     1 TB       = 1024 GB

EXAMPLE:
Original size/capacity = 40995 MB

P1   - 50 %             =      40995 x .50       =        20498    
P2   - 50 %             =      40995 x .50       =        20498 

Original size/capacity = 40995 MB

P1   - 25 GB           =      25 x 1024         =         25600
P2   - 25  %            =      40995 x .25      =         10249
P3   - The rest    
  

Original size/capacity = 38162 MB

P1   - 15 GB           =      15 x 1024          =        15360 
P2   - 30 %             =      38162 x .30       =        11449
P3   - 100%           

Original size/capacity = 38162 MB

P1   - 39 %            =      38162 x .39         =        14883
P2   - 11 GB           =      11 x 1024            =        11264
