Memory Management in Operating Systems. Binding delayed until run time ssytem the process can be moved during its execution from one memory segment to another.

Input queue — collection of processes on the disk that are waiting to be brought into memory to run the program. Mansgement and physical addresses are the same in compile- time and load-time address-binding schemes; logical virtual and physical addresses differ in execution-time address-binding scheme.

Program must be brought into memory and placed within a process for it to be run. Page 4 Silberschatz, Galvin and Gagne?

Binding delayed until run time if the process sjstem be moved during its execution from one memory segment to another. Must generate relocatable code if memory location is not known at compile time.

Physical address — address seen by the memory unit. Page 4 Silberschatz, Galvin and Gagne? Input queue — collection of processes on the disk that are waiting to be brought into memory to run the program.

Must generate relocatable code if memory location is not known at compile time. User programs go through several steps before being run.
