In DOS terminology, restarting the operating system without turning system power off is referred to as what type of boot?

Introduction / Context:
Boot terminology distinguishes between restarts that cycle power and those that do not. In DOS-era PCs, technicians commonly initiated a non-power-cycle restart to recover from software issues without completely resetting the hardware environment.

Given Data / Assumptions:

• System remains powered; only the OS and software state are reinitialized.
• Common triggers include Ctrl+Alt+Del or issuing a reboot command.
• Hardware is not fully power-cycled.

Concept / Approach:
A warm boot restarts the system without removing power, reinitializing software and many hardware registers but typically leaving power on to components. A cold boot, by contrast, follows a complete power cycle or hard reset. DOS documentation and technician jargon consistently label the former as a warm boot.

Step-by-Step Solution:

Verification / Alternative check:
Using Ctrl+Alt+Del on DOS reboots without powering off, confirming “warm boot” behavior.

Why Other Options Are Wrong:

• reboot: Generic term that does not specify warm vs cold.
• shutdown / system up: Do not denote this specific restart type in DOS jargon.
• None of the above: Incorrect because warm is the precise term.

Common Pitfalls:
Assuming all reboots are the same; documentation often requires distinguishing warm from cold for hardware initialization issues.

Final Answer:
warm
