check the priority

They are either handled based on priority or put in queue as they come. CHeck the answer.

Deadlock will occur.To overcome from this problem process scheduling algorithm is used.

They are handled based on priority ,highest priority interrupt will be executed. there are basically two modes of execution Privilege mode and user mode. In Privilege mode only previlege instructions will be executed.when multiple interrupts occur processor check for the priority and handled accordingly.

Actually all the jobs are processed by following a specific scheduling algorthim. So when multiple interrupts occur at the same time then CPU handles these tasks according to the priority.

There are some schedulling algorithms?to control the?multiple interrupts?so many os ?mostly used priority based algorithm in this each process alloted with their priorities in that time they will execute.

If not used any algorithms tat may lead to deadlock state.

Just a note: In user mode, only non-privileged instructions are available. In privileged mode _all_ instructions are available. Thus the user mode has access to a subset of the CPU's available instructions while privileged mode has access to the whole instruction set.

The operating system runs in privileged mode so that it can set values for things such as the TLB or the memory access registers. User processes can call into the system through standard traps; interrupt handlers also run in privileged mode so that they can interact with ports and/or drivers at a very low level.
