1. (21%) Suppose we have 10 applications each of 100K size and we have RAM equal to 512K and OS of size 20K.

Can two applications run in the memory at the same time in the mono programming environment (which means only one program can run at a time, slide #3 )? Why?

Can two applications run in the memory at the same time in the swapping environment (slide #8) ? Why?

Can two applications run in the memory at the same time in the virtual memory (paging) environment (slide #13) ? Why?

2. (24%) (a) (12%) Repeat all the three parts of Q1 now assuming that each application is of size 400K.

(b) (12%) Repeat all the three parts of Q1 now assuming that each application is of size 800K.
