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

P3   - 100%                               
            

Original size/capacity = 40995 MB

P1   - 41 %             =      40995 x .41          =        16808

P2   - 10 GB           =      10 x 1024             =        10240

P3   - The rest

Example:

For example, the address 168.212.226.204 represents the 32-bit binary number 10101000.11010100.11100010.11001100.

IP Versions

The Difference Between IPv4 and IPv6 Addresses. An IP address is binary numbers but can be stored as text for human readers. For example, a 32-bit numeric address (IPv4) is written in decimal as four numbers separated by periods. ... IPv6 addresses are 128-bit IP address written in hexadecimal and separated by colons.

BINARY

- Binary describes a numbering scheme in which there are only two possible values for each digit: 0 and 1.
