Well you can have a look at the book named "Intel® 64 and IA-32 Architectures Software Developer's Manual, Volume 3A"
What do you want to do after knowing this ?
[I then began to program a operating system]
alt+delete+control is proected mode.
CPU protection Memory protection I/O protection Dual mode protection. Research more about these and maybe you will get where you are going.
yes...yes it is
the property protection is available on the properties page. at this stage you do not need property protection because the robbing mode is disabled.
No, the service mode on A jandy or pentair system, is just that for service the whole system is shut down in service and the equipment can only be turned on manually. So in other words the "freeze" protection has been turned off in the service mode.
define and explain hardware protectoin
The distinction between kernel mode and user mode provides a rudimentary form of protection in the following manner: Certain instructions could be executed only when the CPU is in kernel mode. Similarly, hardware devices could be accessed only when the program is executing in kernel mode. Control over when interrupts could be enabled or disabled is also possible only when the CPU is in kernel mode. Consequently, the CPU has very limited capability when executing in user mode, thereby enforcing protection of critical resources.
It will conduct electricity when the voltage across its terminals reaches a certain value. Once the over voltage is extinguished, the protection diode becomes an open circuit again. Therefore, you need to connect a protection diode between both wires to be protected (differential mode) and from each wire to ground (common mode). Protection diodes are primary protection devices (fast reacting), but they cannot handle too much current. That is why they need to be used with secondary protection devices (fuses and gas arrestors) to provide better protection.
Windows NT uses protection mechanism called rings provides by the process to implement separation between the user mode and kernel mode.
This is to prevent damage. You may have something not connected correctly or parts that are not compatible.
A shorted output, bad output transistor. need more info.
Just try to restart the system in safe mode and download any antivirus.
