Assume we are dealing with a system that places programs in memory following a first-fit dynamic partitioning scheme. At some point in time, we have just loaded a program that needed 48 MB, and memory is as depicted below (not to scale). Shaded (blue) regions are full, blanks are holes (with sizes in megabytes as indicated); the cross-hatched region is the location of the most recently loaded program, it is at least 48 MB in size. Show, on the memory diagram, where the following sequence of new programs will be positioned and the resultant holes. The programs require in order 32MB, 7 MB, 10 MB, 5 MB, and 35 MB of memory. Show memory at each modification.  

A risk with ___________ is the possibility of starvation for longer processes, as long as there is a steady supply of shorter processes.

In the dynamic partitioning technique of memory management, the placement algorithm that scans memory from the beginning of memory and chooses the next available block that is large enough to satisfy the request is called
