Answer:
Job of an Operating SystemEdit
Coordination Edit
The goal of an operating system (OS) is to allow multiple applications and users to work together in fair and efficient ways.
security - prevent jobs from interfering with one another
communication - let jobs talk to one another
resource management - give jobs fair share of resources
Abstraction / Standard Services Edit
An operating system provides a set of standard services (or API) for applications to use the various system resources. Instead of forcing every application programmer to know how to write a complicated device driver just to read the CD-ROM, for instance, a modern-day operating system will simply provide a routine to access the device. This not only simplifies the job of an application programmer, but also provides the ability to manage system resources effectively and protects against malicious behavior. We will explore the trade-offs that decisions about operating system designs involve when we introduce the concept of a kernel.
