What is the purpose of DOS tools and what are the functions of DOS tools?

inspect and repair hardware, find and clean up malware; ......

A software box that integrates a lot of utilities, such as the classic Dwarven DOS Toolbox.

You can enter the DOS command plane, and you can perform system operation, restoration, and so on.

1) What is DOS? What's the use?

The most frequent contact we use the computer is the abbreviation of the English disk operating system, which means "disk operating system", as the name suggests, DOS is mainly a disk-oriented system software, to put it simply, DOS is a bridge between man and machine, is a layer of "shell" covered in the machine hardware, with DOS, we don't have to have an in-depth understanding of the hardware structure of the machine, nor do we have to memorize those boring machine commands, With just a few DOS commands that are close to natural language, we can easily complete most of the daily operations. In addition, DOS can also effectively manage various software and hardware resources, schedule them reasonably, and all software and hardware are under the monitoring and management of DOS, and carry out their work in an orderly manner.

b) MS-DOS vs. PC-DOS

We also often hear about MS-DOS and PC-DOS when using DOS, and for beginners, it can be considered that there is no big difference between the two. In fact, MS-DOS is produced by Microsoft, the world's software king, while PC-DOS is a slight modification of MS-DOS by IBM (International Business Machines Corporation), the world's computer king. Due to Microsoft's monopoly advantage in the world's software industry, its product MS-DOS has become the mainstream operating system, as for PC-DOS, although it is not necessarily inferior to MS-DOS in terms of function, MS-DOS is preconceived, and PC-DOS has never been able to shake MS-DOS even if it has tried its best.

c) DOS version.

The DOS was launched in 1981 with very basic and weak features; Launched in 1983, it mainly added the function of directory operation, which brought file management to a new level (the concept of directory and file will be introduced when explaining the internal commands of DOS); Launched in 1984, it mainly supports inch high-density floppy disks (and only low-density disks) and high-capacity hard disks; 1987 Launched the most popular DOS at present, mainly supporting inch floppy disks and networks. At this point, DOS has developed quite maturely, although the subsequent versions (the latest version of PC-DOS is the version, and the latest version of MS-DOS is constantly being launched), there are no major kernel improvements, but many practical functions have been added, such as detecting disks, removing viruses, increasing the capacity of hard disks, etc.

DOS is the most basic operating system software, and DOS is the abbreviation of Disk Operation System in English.

A DOS system is made up of a set of important programs provided by a floppy disk or hard disk. The core of the DOS system consists of three boot modules and a boot module, which are the input and output module (IOSYS), the file module (MSDOSSYS) and the command processing module (Commandcom).

The purpose of the bootloader is to load the two DOS boot modules and the memory of the two hidden hailstones when the computer starts. The main role is to manage input and output devices. It is used to manage disk files and system resources.

It is the outermost module of the entire DOS system, and its task is to interpret and execute the commands entered by the user.

Start-up of the DOS system

In order to use the DoS system on disk, the DoS system must be transferred to the internal memory of the computer, which is called the boot of the DoS system.

In addition to starting the DOS at the time of boot (this kind of startup, generally known as cold start), in the operation of the microcomputer, if for some reason, the microcomputer operation is in an endless loop or other crash situation, it is also necessary to restart the DOS. Press the (Ctrl) 10 (ALT) (DEL) key to restart the DOS. The panel of the computer with the sale of sails is equipped with a hole button, which can also be pressed to restart the DOS.
