What are the benefits of ISO files?

1.What is an ISO file.

ISO file: It is a file with ISO as the extension, which is the ISO9660 file format, a file system format on a compact disc (CD). To put it simply, it's how the data is organized on a data disc:

It is characterized by:

1) Contains up to 8 levels of subdirectories (you can increase this limit with the rockridge extension).

2) The maximum file name is 32 characters.

3) The file size should not exceed 650M

2.How to use ISO files under Linux.

Normally, the kernel of the Linux system supports the ISO9660 file format, if it is not supported you need to recompile the kernel to add support for it.

You can simply use the following command to read its contents from the path directory:

mount -t iso9660 -o loop /path

3.If you engrave it into a disc.

With disc burning software under Windows, it can do this job directly.

4.How to make an ISO file in a Linux system:

In the Linux system, we can copy the contents of the optical drive to an ISO file through the copy command, such as:

cp /dev/cdrom

ISO files need a virtual disc drive to open, and the advantage is that it is convenient to burn the disk.

You can directly drag it into a blank disc and burn it. When you open the disc after burning, you will see the unwrapped folders and files.

If it's a different compression format, it won't be automatically decompressed to a disc after burning.

1. ISO file is an image file of the CD, the burning software can directly burn the ISO file into an installable system CD, the ISO file is generally extended by ISO, and its format is ISO9660.

2. In order to enhance cross-platform and in-tolerance, ISO defines a minimum subset of common file attributes and name attributes, file names, extensions, and versions, and uses a separate system area to be compatible with future extension attributes.

3. The ISO can be "mounted" by the appropriate driver software, that is, the operating system emulates and treats it as if it were a physical disc. Most UNIX-like operating systems, including GNU Linux and Mac OS X, offer built-in functionality to mount ISOs, and Windows 8 also provides this functionality. Other software can also bury the driver into the operating system for the same purpose.

4. The ISO file only stores the user data of each sector on the disc, and the bend bridge will ignore the control head and error correction data, so it is slightly smaller than the original image of the disc media. Because the user data for each logical sector on the disc is 2,048 bytes, the size of the ISO image is based on 2,048 bytes.

ISO common systems are: information security management system (ISO27001), information technology service management system (ISO20000), quality management system (ISO9001), property service certification (GB T environmental management system (ISO14001), occupational health and safety management system (ISO45001), medical device quality management system (ISO13485) For more information, please consult Huayi Certification Center **** (referred to as Huayi certification, English abbreviation HYC), is an approved third-party certification body, (certification body approval letter: CNCA-R-2018-419), with the qualification to engage in third-party certification.

Image fileIn fact, it is a separate file, and unlike other files, it is made of multiple files through burning software or image file creation tools. Image files are widely used, and the most common application is data backup. With the popularization of broadband networks, some **** also have ISO format files**, which facilitates the production and transmission of software discs.
