What is a DOS laptop?
Ever heard about DOS based laptops? Well, I doubt most of you have heard about it. DOS or Microsoft Disk Operating System is one of the simplest operating systems, that certainly most of us would ever ask for.Â
 It was created by Microsoft back on August 12, 1981, when people were not so familiar with computers. At that time computers were just upgraded from hard-wired to punch cards and then, after that, magnetic tapes to carry out specific computations.
 When the instructions to control a computer were transferred onto a disc drive, such as a floppy disc or an internal HDD, it was considered as cutting-edge technology. DOS is also used to refer to a group of command-line disc operating systems.Â
 Early computers, such as the Commodore 64, Atari 800, and Apple II, all had disc operating systems, such as Commodore Business Machines DOS, Atari DOS, and Apple DOS. DOS/360 was an operating system for IBM mainframes that debuted in 1966, although it is unrelated to the 8086-based DOS of the 1980s.
 To use MS-DOS, users must memorize and understand the command. However, to address this issue, MS-DOS was eventually superseded by GUI (Graphical User Interface) operating systems like Windows. And therefore as of December 31, 2001, Microsoft no longer supported the DOS operating system.
 Anyways, still today in this intricate society where specifications and latest computing features are prioritized, there are many people who are still interested in DOS computers. DOS laptops are still famous among programmers and hackers.Â
 Today, the DOS laptop is primarily utilized for three purposes, legacy bus software support, vintage DOS games, and embedded systems. While there is a lot of DOS abandon ware accessible, there isn't a lot of commercial software being created nowadays.
 Due to its simple design and low memory and CPU needs, MS-DOS is still used in embedded x86 systems. However, some recent products have moved to the still-maintained open-source alternative Free DOS. Microsoft released the source code for MS-DOS 1.25 and 2.0 on GitHub in 2018.
 When we consider all of the goods on the market, the dos laptop price varies. When it comes to laptops, the Lenovo Ideapad 330-15ARR (81D2008WIN) Laptop (AMD Quad Core Ryzen 5/8 GB/1 TB/DOS), and HP 240 G7 (1S5F1PA) Laptop (Core i3 10th Gen/4 GB/1 TB/DOS) are somewhat more expensive. On the other hand, when it comes to budget laptops, the HP 245 G7 (7GZ75PA) Laptop (AMD Dual Core A6/4 GB/1 TB/DOS) is somewhat cheaper, that costs $277.65 USD.
 Dos-based laptops feature only a character-based interface system where all commands are entered in the text at the command-line prompt. It is basically a disk operating system that can manage a computer's files, I/O system, and its memory.Â
 Disk operating systems were crucial in the early development of personal computing. Today, some 55 years after their original invention, they are regarded as one of the most important types of operating systems in computer history.
