DOS is a program, so it's software. Hardware is the physical machine parts.
DOS
There is nothing called lenovo DOS OS. DOS is the operating system which can be loaded in lenovo hardware..
Who told you? Windows uses more resources than DOS.. As we know that DOS can support less hardware than Windows and BIOS is the controlling system for integrated hardware, hence we can easily understand the utilization of DOS and Windows..
Access the hardware directly: possible in DOS, not possible in Windows.
It is a computer operating system, therefore it is a software. No.
the very basic os --MS-DOS allows uers to directly have access to hardware
MS-DOS was initially released in 1981 for the Intel 8086 and 8088 based processors. There are no software requirements for MS-DOS as it is a stand-alone operating system. MS-DOS is compatible with x86 systems.

POST stands for Power On Self Test.. It examines all the hardware and settings for optimize working at the time of boot..
Disk Operating System (DOS) can be considered stable for its intended use, particularly in legacy systems or specific applications that require a lightweight operating environment. However, its stability can be impacted by hardware compatibility and the limitations of its single-tasking architecture. For modern computing needs, DOS may not be suitable, as it lacks support for contemporary hardware and software advancements. Overall, while stable within its niche, it may not meet the demands of current technology environments.
That'd be software installed directly onto a piece of hardware which is the operating code for that piece of hardware. For example, a hardware RAID controller might have firmware on it that controls its operation.
