How to understand Linux partitions, how to divide them, and which version should beginners use?

The primary partition is in ext4 format and the other is in swap partition format.

1. Linux requires at least two partitions, the main partition is ext4 format, and the other is swap partition format.

2. The new version of Linux generally needs 3 partitions when installing

The first is the boot partition, which is used to install boot information such as UEFI and other boot information, usually in ext2 and ext4 format;

The second is to install the ext4 partition where the system and files are stored.

The third is a swap partition dedicated to exchanging data with memory and being used as a cache.

3. The mode of Linux management files is different from Windows, it is the folder mode, in the Linux system, the new hard disk is also mounted to the main partition in the form of folders, instead of using the partition mode of Windows, usually you can only see the ext4 partition, and you can not see the Linux boot partition and the swap partition.

1. Boot partition: mount point boot, partition format ext4, within 500M.

3. Home directory: mount point, partition format ext4, size about 20 40g.

4. Home directory: mount point home, partition format ext4, all the remaining space.

ext2 and ext3 are more commonly used, but the latest ubuntu is already using ext4. That's what I use. On the other hand, there are some embedded Linux systems that commonly use JFFS and YAFFS file systems.

Moreover, Linux supports almost all file system types (i.e., classified types) that you knowIncluding FAT32, NTFS, etc., which are commonly used under Windows.

Two of the first is the basic type (not in the score).

One is the extension type * (which can be in points).

1. ext2: is the standard file system in GNU Linux. This is one of the most widely used file systems in Linux, it is specially designed for Linux, has extremely fast speeds and minimal CPU usage, and can be used both for standard block devices and for removable storage devices such as floppy disks.

2. ext3: ext3 is a log file system, the biggest feature is: it will completely record the write action of the entire disk on a certain area of the disk, so that it can be traced back when necessary.

When a process is interrupted, the system can directly backtrack and restructure the interrupted part based on these records, which is quite fast.

3. Linux swap: It is a swap file system in Linux that is specially used for swapping partitions. Linux uses the entire partition as the swap space, and the swap partition is usually twice the main memory, and when the memory is insufficient, Linux will write part of the data to the swap partition.

4. VFAT: also known as long file name system, this is a Linux file system compatible with Windows system, supports long file name, and can be used as a partition for exchanging files between Windows and Linux.

Linux is the hottest operating system in 1999, and its disk partition format is completely different from other operating systems, there are two types. One is the Linux Native primary partition and the other is the Linux Swap swap partition. The security and stability of these two partition formats are excellent, and when combined with the Linux operating system, the chances of crashes are greatly reduced.

However, the only operating system that supports this partition format is Linux.

The primary partition is either ext3 or ext4

It also depends on what Linux you use.

CentOS Redhat generally uses ext3 ext4

Linux file system formats are quite complex and diverse, such as ext, ext2, ext3, ext4, jsf, xfs, reiserfs, etc.

In general, most of the Linux root partition file systems use ext3 and ext4, which you can choose when installing.
