Data subsystem
The virtual memory subsystem and the storage subsystem are typically tightly-coupled and require careful design in a layered system due to the following interactions. Many systems allow files to be mapped into the virtual memory space of an executing process. On the other hand, the virtualmemory subsystem typically uses the storage system to provide the backing store for pages that do not currently reside in memory. Also, updates to the filesystem are sometimes buffered in physical memory before it is flushed to disk, thereby requiring careful coordination of the usage of memory between the virtual memory subsystem and the filesystem.

a computer on the whole is a system ... it has a lot of subsystems .. these subsystems are said to be the computer subsystem ... thus in simple words , a subsystem found in a computer system is said to be a "Computer Subsystem"
There are two ways of communicating with a subsystem, either by sending stimuli to the subsystem itself to be re-directed to the proper recipient inside the subsystem, or by sending stimuli directly to the recipient inside the subsystem. In the first case, an association is defined with the subsystem itself to enable stimuli sending.A subsystem can have generalizations to other subsystems, i.e., the public and protected elements in the contents of a subsystem as well as operations and receptions are also available to its heirs.A subsystem may offer a set of interfaces, i.e., for each operation defined in an interface, the subsystem offering the interface must have a matching operation, either as a feature of the subsystem itself or of a specification element.
Strength Management is an interrelated subsystem of the EPMS.
it is a subsystem that assist the circulatory system
an ideological subsystem is the ideas, beliefs, knowledge, and means of their communication that characterize a culture.
Thrashing occurs when a computer's virtual memory subsystem is in a constant state of paging, rapidly exchanging data in memory for data on disk, to the exclusion of most application-level processing. This causes performance of the computer to degrade and collapse.
The three subsystems of Culture: technological subsystem sociological subsystem ideological subsystem
No, there is usually also ROM, and some type of NOVRAM (e.g. battery backed up CMOS RAM). In some architectures I/O ports may also be mapped into the memory address space.
