Disk partitioning is the generic name given to each division present in a single physical unit of data storage that can be a key factor when Buying a Laptop Online. A hard disk partition is a logical division in a storage unit (such as a hard drive or flash drive). There are different partitioning schemes for the distribution of partitions on a disk.

The most popular and widespread are MBR (Master Boot Record) and GPT (GUID Partition Table). Partitions to hold data must have a file system. The unallocated space on a disk is not a partition, therefore, cannot have a file system.

Optical discs (DVD, CD) use other partitions called UDF (Universal Disc Format), which allows you to add files and folders. This is why they are used by most software packet writing and recording programs known as optical drives. This file system is mandatory units for DVD but also allowed for some (CD).

In Windows, the recognized partitions are identified with a letter followed by a two-point sign (eg C : \). virtually all types of magnetic disks and flash drives can be partitioned.

On UNIX and UNIX-like systems, data partitions are mounted on one and the same hierarchical tree, in which they’re mounted through a folder, a process that only the superuser (root) can perform.

However, to be able to use more partitions on a single disk, extended partitions are needed, which can contain an unlimited number of logical partitions within. It is necessary to note that only the primary and logical partition can contain a file system itself .

Partition Types

The format or file system partitions (eg NTFS ) should not be confused with the partition type (eg, Primary partition), because it actually does not directly have much to do. Regardless of the file system of a partition (FAT , ext3 , NTFS , etc), there are 3 different types of partitions:

Primary partition: there can be only 4 of these or 3 primary and one extended. It depends on a partition table. A fully formatted physical disk is actually a primary partition spanning the entire disk space and has a file system.

With this type of partition, virtually any operating system can detect and assign a unit as long as the operating system recognizes the format (file system). Extended partition: Also known as secondary partition, it is another type of partition that acts as a primary partition, used to contain multiple logical drives inside. It was designed to break the limitation of 4 primary partitions on a single physical disk. Always take note before buying laptop online that you must understand where it will be use.
