Can a monitor display 2 inputs at once?
No. All monitors with more than one HDMI input can only present one input at a time. This is done with some sort of switch or switches commonly called the monitor input select switch. There is no way for any monitor to display two video pictures simultaneously.
What causes a CPU to overheat?
As electricity passes through the CPU or gets blocked inside, it gets turned into heat energy. While a processor in a high-performance workstation may run hot due to heavy use, a processor in a regular computer that overheats is almost always a sign of a malfunctioning system.
Why is it important that the CPU can be interrupted?
Interrupts are important because they give the user better control over the computer. Without interrupts, a user may have to wait for a given application to have a higher priority over the CPU to be ran. This ensures that the CPU will deal with the process immediately.
What happens when a CPU receives an interrupt?
When an interrupt occurs, it causes the CPU to stop executing the current program. The control then passes to a special piece of code called an Interrupt Handler or Interrupt Service Routine. The interrupt handler will process the interrupt and resume the interrupted program.
Can interrupts run on multiple CPU cores at the same time?
If that processor has more than one CPU can the interrupts run on different cpu cores at the same time. There is always a hierarchy of interrupt signals. The highest priority one is the first seen by the CPU and acted upon.
Can two interrupts be serviced at the same time?
Two interrupts cannot be serviced at the same time: at least some key portion of the actions of servicing an interrupt is necessarily serialized: the portion when the CPU acknowledges the interrupt and dispatches a handler.
How do I switch between two computers with the same keyboard?
A “KVM (Keyboard, Video, Mouse) switch” is used so two computers share the same keyboard/mouse and monitor. There is a button on the KVM you press to switch between computers. The monitor only needs to use one input.
How does a computer decide which interrupt goes through first?
Historically, this is dealt with by some piece of hardware (perhaps called an “interrupt controller”) which multiplexes the interrupt lines and makes a decision about which interrupt gets through, based on some priority scheme (perhaps programmable, or else fixed).
