Installing the system-Summary of professional terms

 

Installation System terminology

The head of system installation is a bit painful, especially for those who are still blind to computer knowledge, I feel dizzy with the overwhelming professional terms alone, however, simply sum up, you will feel suddenly enlightened. Let's sum up.

I. What is an ISO file?

An ISO file is actually an image file of a CD. The recording software can directly burn an ISO file to an installable system CD. The ISO file is generally based on the ISO extension, and its file format is iso9660.

Most of the Linux installation files we downloaded are in ISO format. After downloading them to a local device, double-click the files to be opened by WinRAR. Many people regard the files as compressed packages, which is incorrect, the ISO file can be directly installed on the hard disk Without decompression.

Features of ISO files:

1) a maximum of 8 sub-directories can be included (you can use Rockridge extension to increase this limit)

2) The maximum file name is 32 characters.

3) generally, the file size cannot exceed 650 mb. The actual size can be changed based on the size of the CD or DVD.

[1] Many Linux operating systems and some Pirated Windows Installation packages on the network are released in the form of ISO files. After obtaining the corresponding ISO file, you can burn the content on the CD. The purchased and installed discs are basically the same.

2. What is an image file?

The so-called image file is actually similar to the zip package. It makes a specific series of files into a single file in a certain format, so that users can download and use it conveniently, for example, a test operating system or game. Its most important feature is that it can be identified by specific software and can be directly burned to a CD. Generally, the image file can be expanded to include more information. For example, system files, boot files, partition table information, etc. In this way, the image file can contain all the information of a partition or even a hard disk. The classic software that uses such image files is ghost, which also supports the burning function. However, it only saves the image file on the CD, in general, the recording software can directly burn the content contained in the supported image files to the CD. In fact, the image file is the "extract" of the CD ".

How to Use image files

Image files cannot be directly used. You need to decompress them using some virtual optical drive tools before using them. The principle of the virtual optical drive is the same as that of the physical optical drive. For example, if you buy a genuine disc, you can add the game disc to the physical optical drive to smoothly perform the game, the image file (ISO file, equivalent to a game disc) must be added to the virtual optical drive. After you have loaded the virtual optical drive, an additional optical drive will be added to your computer, that is, the virtual Optical Drive. Double-click the shortcut of the virtual optical drive on the desktop. You can find an icon in the lower right corner of the desktop. You can right-click the icon to perform operations and load the image file to complete game installation, after installation, you can load the required image to the game .. Daemon
Tools is a good virtual optical drive file, which can be used to directly virtualize the ISO file as a CD file. The installation of daemon tools is very simple. After copying files, the system will prompt you to install a new hardware of the virtual optical drive. You need to restart to install the software and hardware. Daemon
Tools can be automatically set to auto-start. Only a small icon is generated on the taskbar. You can click the icon and select the ISO file location from the menu to virtualize the ISO file into a CD. In fact, there are still a lot of software for extracting image files, such as Genie virtual optical drive and poweriso!

Common image file formats include:

. ISO,. Bin,. NRG,. VCD,. CIF,. FCD,. IMG,. CCD,. C2D,. DFI,. Tao,. Dao,. Cue, etc. The formats of image files supported by each recording software are different. For example, Nero supports. NRG,. ISO,. Cue, And. Easy CD creator supports. ISO,. CIF, and clonecd supports. CCD.

Formats of image files created by various software

Media descriptor image file *. MDs

Clonecd image file *. CCD

Cue-sheets image file *. Cue

Blindread image file *. BWT

Standard ISO image file *. ISO

Discjuggler image file *. CDI

Nero image file *. NRG

Instant CD/DVD image file *. PDI

Blindwrite V5/v6 image file *. b5t

Compressed ISO image *. isz

3. What is winpe?

Windows preinstallation environment (Windows PE), Windows pre-installation environment, is the minimum Win32 subsystem with limited services, based on Windows XP Professional kernel running in protected mode. It includes the minimum features required to run Windows Installer and script, connect to network sharing, automate basic processes, and perform hardware verification.

Windows pre-installation environment (Windows PE) is a minimum computer operating system designed for Windows installation. It can be used to start a computer without an operating system, partition and format a hard drive, copy a disk image, and start a Windows Installer from a network share. Windows PE can be used as a customer-oriented independent product with an appropriate authorization protocol. It is a component that integrates many windows technologies, including Windows Installer and Windows Deployment Service (Windows DS.
Windows PE 2.0 is the latest version based on Microsoft Windows Vista. The Windows PE Cd (including the ISO image CD on my hand) that most people get should be a "Windows XP opk" CD, which means Windows xp oem pre-installation kit CD. In fact, Windows XP opk CD is a 32-bit boot copy of Windows PE. That is to say, this CD is already an operating system defined by Windows PE, we can use it directly to guide the system. Let's take a look at the directory structure of this CD. The total size is 352 mb. Is it a little big? In fact, this is a copy (including at least a lot of drivers), the size is determined by the Custom production at that time, if it is a Windows
PE's 32-bit non-custom version, and its disk image is about 120 MB

4. What is a gho file?

The gho file is the image file of the ghost. Generally, after downloading an ISO image file to a local device, you will find a file with the suffix gho. At present, there are usually Yulin Mufeng, lubu jiayuan, and Computer City installation versions on the Internet. You can copy the downloaded ISO file through the Virtual optical drive, and then use the ghost

5. What is ghost?
Ghost, originally known as a ghost, is the soul of the dead, and again appeared in the world as it was before life. Generally, a ghost does not have a fixed shape and is invisible to the naked eye. It can only be seen in certain situations. Now we are talking about the ghost, which is more about the system disk, that is, the installed system. The ghost makes the system installation easier.

6. What is a virtual optical drive?

Virtual optical drive is a kind of simulation (CD/DVD-ROM) tool software, can generate and your computer installed on the optical drive function identical to the CD image, generally, an optical drive can do the same thing as a virtual optical drive. The working principle is to virtualize one or more virtual optical drives, and then store the application software and images on the optical drive on the hard disk, and generate an image file for the virtual optical drive, and then you can put this image file into the virtual optical drive for use. Therefore, when you want to start this application in the future, you do not have to put the CD in the optical drive, you don't have to wait for the drive to start slowly. Just tap the insert icon and mount the virtual disc to the virtual drive immediately for fast and convenient operation.
Common virtual optical drives include vdm and daemon tools.
