在资源分区方式中，操作系统预先决定把哪些资源分配给某个 用户计算使用，这种方法也称为静态分配，因为分配是在程序 执行前进行的。静态资源分配易于实现，但由于它不是从程序 的实际需要出发，而是根据程序预先提出的需求来做决定，所 以容易导致系统利用率下降。

5.1.1 Resource allocation and related functions
In the partitioned resource allocation approach, the OS decides on the resources to be allocated to a program based on the number of resources and the number of programs in the system. For example, an OS may decide that a program can be allocated 1 MB of memory, 2000 disk blocks and a monitor. Such a collection of resources is referred to as a partition. In effect, a set of partitions can be predefined in the system. The resource table can have an entry for each resource partition. When a new program is to be started, an available partition is allocated to it.

System software, or systems software, is computer software designed to provide a platform to other software. Examples of system software include operating systems, computational science software, game engines, industrial automation, and software as service applications. In contrast to system software, software that allows users to do things like creating text documents, laying games, listening to music, or surfing the web is called application software.
Part A Theoretical study section
Skill one System Software------OS
Operating Systems or System Control Programs An operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs. It provides a platform (hardware abstraction layer) to run high-level system software and application software. A kernel is the core part of the operating system that defines an API for application programs (including some system software) and an interface to device drivers.
