What is the difference between GPT and MBR?
by Bella Martin Software engineerGPT stands for GUILD Partition table and MBR stands for
Master Boot Record. Most of the people have elementary information or no
information about it and due to this they don’t even bother but these two are
the most important architecture developed for creating partition for user to
store their stuffs. MBR is the first technology developed in the early 1980’s
for DOS compatible computer. MBR is the first 512 bytes located on the first
sector of the disk which defines the partitions on the disk and boot code for
the computer. Incase of MBR only a user can create maximum of three partitions.
Even when the disk size increases above 2TiB (240 bytes) the MBR
architecture fails. These drawbacks gives rise to the need of a new
architecture so Intel came up with its new architecture which is popularly
known as GPT and is attached with the UEFI. GPT is the acronym of GUID
Partition Table. GUID is a 128 bit numeric code used for software program to
identify the exact location of a data object on the disk space. Some of the objects that use GUID are media
files, doc files, Windows registry files etc. GUID is the acronym of Globally
Unique Identifier. GUID use hexadecimal notation of 36 characters and for a doc
file it look like this:
{23894723 – 8903 –
1232 – 2348 – 789634951026} used for a MS Word document.
·
GPT allow user to make 128 partitions on the disk space
which can be used by user for their own. The numbers of partitions depend on
the amount of space available for creating Partition entries.
·
GPT allow a user to manage disk space 2 ZiB (270
bytes) thus offer more flexibility to user. GPT is used in Windows OS computers
as well as in Macintosh computers. In GPT first block is reserved for
protective MBR for ensuring compatibility with previously disk management
utilities that are associated with used with MBR.
·
In case of MBR rules for creating partition are complex and
poorly specified so GPT is preferred in comparison to the MBR. MBR is the only
partition architecture scheme available until development of Windows server
2003. All x86 and x64 use MBR format.
What about Removable media?
Generally the removable media has only one partition or have
MBR format to create partitions. The removable media which only constitute one
partition are also categorized under new category named as “Superfloppy”. Removable
media include floppy disk drives, JAZ disk cartridges, magneto optical disk,
CD/DVD where as external hard disk which communicates through SCSI or IEEE 1394
are not categorized under removable media.
If you want more information regarding the partition
creation scheme developed for windows operating system used in the windows
operating system then you can visit Impcsupport website. They also provide online technical support 24*7 for 365 days. They also provide
reliable software solution for resolving computer problems or you can use computer maintenance tools or windows maintenance tools for enhancing
the speed and performance of your computer system.
Summary:
MBR and GPT are the two schemes developed for creating
partitions and converting disk space to user managed storage space. GPT is the
latest one which offers a user to create partitions of space greater the 2 TiB
