This article mainly shows you "what are the reasons why linux needs partitioning", the content is simple and easy to understand, and the organization is clear. I hope it can help you solve your doubts. Let Xiaobian lead you to study and learn "what are the reasons why linux needs partitioning".

Linux partition reasons: 1, partition can prevent data loss, once the partition is not damaged, users will lose all data;2, partition can increase disk space efficiency;3, partition can separate user data from system data, can avoid user data filling the entire disk.

Operating environment: Linux 7.3 system, Dell G3 computer.

Why Linux should be partitioned

Partitioning is the division of a hard disk drive into logical drives. Partitioning is the use of contiguous blocks of hard disk as a separate magnetic hard disk. A partition table is an index of hard disk partitions, and partition information is written into the partition table.

What are the benefits of Linux partitioning?

Data loss prevention: If the system has only one partition, the user will lose all data if the partition is damaged.

Increase disk space efficiency: You can format partitions with different block sizes. If there are many 1K files and the disk partition block size is 4K, then each file stored will waste 3K space. In this case, we need to take the average of these file sizes for block size division.

Avoid System Suspends: Separating user data from system data prevents user data from filling up the disk and causing system suspends.

What are Linux partition formats?

Ext2 is the standard file system in GNU/Linux. This is the most widely used file system in Linux, it is designed specifically for Linux, with extremely fast speed and very small CPU usage, can be used in both standard block devices, but also applied to removable storage devices such as floppy disks.

Ext3: Ext3 is a log file system, the biggest feature is that it will record the entire disk write action completely on a certain area of the disk, so that it can be traced back when necessary. When a process is interrupted, the system can trace back directly from these records and reorganize the interrupted part, which is quite fast.

Linux Swap: It is a Swap file system in Linux that is specifically used to swap partitions. Linux uses this entire partition as swap space. Generally, the swap partition in this Swap format is twice as large as the main memory. When there is not enough memory, Linux will write some data to the swap partition.

4, VFAT: also known as the long file name system, this is a Linux file system compatible with Windows systems, support long file names, can be used as Windows and Linux file exchange partition.
