With a page is brought into main memory only when the reference is made to a location
on that page.
provides a larger sized of virtual memory but require virtual memory which provides
multidimensional memory.
is a large kernel containing virtually the complete operating system, including,
scheduling, file system, device drivers and memory management.
is a large operating system core provides a wide range of services.

i) Multithreading is useful for application that perform a number of essentially independent tasks that do not be serialized.
ii) An example of multithreading is a database server that listens for and process numerous client request.
With only one process can execute at a time; meanwhile all other process are waiting for
the processer. With more than one process can be running simultaneously each on a
different processer.
The two central themes of modern operating system are...............
refers to the ability of multiple process (or threads) to share code, resources or data in
such a way that only one process has access to shared object at a time.
is the ability of multiple process to co-ordinate their activities by exchange of
information
Techniques can be used to resolve conflicts, such as competition for resources, and to
synchronize processes so that they can cooperate.
Can be defined as the permanent blocking of a set of processed that either complete for
system resources or communicate with each other.

i) With paging, each process is divided into relatively small, fixed-size pages.
ii) Segmentation provides for the use of pieces of varying size.
The policy segments the disks request queue into sub queues of the length N.
