Dear friend,
there is bit of difference between interrupts &traps.there are two types of interrupts 1> software interrupts 2> hardware interrupt. Trap is a kind of hardware interrupt.hardware interrupts are studied in context with microprocessors or microcontrollers.whenever a microprocessor receives an
interrupt(hardware interrupt as a Trap) it suspends its current execution and saves the address of instruction next to be executed in a special register located within microprocessor.after servicing interrupt routine microprocessor resumes it normal working.
 in  response to ur 2nd que. i would like to state u that scheduling in os is a mechanism through which  an OS(operating system) prioritizes execution of various process in the system. and a time sharing OS(minix  OS for example) allocates the equivalent time slot of its CPU cycle for each process it is executing .in order to understand concept of timesharing OS u can consider a situation of single server minix installed on it and several client workstations are requesting its service.

for answer of remaining two questions u can scroll through wikipedia of OS  .

Thanks ,
