Explanation / Answer

1) ---Trap

A mechanism by which other modules,such as I/O and memory, may interrupt the normal sequencing of the processor is called Trap.

2)-----Multi-programming

A mode of operation that provides for the interleaved execution of two or more computer programs by a single processor is called Multi-programming.

3) ----Virtual address

Virtual address is a memory location in virtual memory that is on disk and at some times in main memory.

4) -----Monolithic kernel

A large kernal containing virtually the complete operating system, including scheduling,file system,,device drivers and memory management is called Monolithic kernel
