Storage management is performed in the first layer. It allocates the main memory space for the process, and reserves a part of the process (page) on a 512K drum when the main memory runs out. On the first layer, the process does not need to consider whether it runs on the drum or in main memory; the first layer software guarantees that when a page needs to be accessed, the page must be in memory.

Layer 2 handles communication between the process and the operator console. At layer 2, you can think of each process as having its own operator console. Layer 3 manages I / O devices and cache-related information flows. At layer 3, each process deals with abstract I / O devices with good characteristics, without having to consider the physical details of external devices. The fourth layer is the user layer. User processes need not consider details such as processes, memory, console, or I / O devices. The system operator process resides in layer 5.
