What is os strategies in operating system?

Answer 1

Strategies in this class address the problem of achieving commonality at the operating system interface. Again there are three approaches, which correspond to the three principal techniques:

• STANDARD OPERATING SYSTEM INTERFACES

  We may achieve portability in part by use of a standard model for the facilities provided, and a standard format for the system calls which access system services.

• PORTABLE OPERATING SYSTEMS

  We may port or retarget the operating system to the new environment (if all users agree to give up the old OS).

• INTERFACE TRANSLATION

  A bridge library may be used to translate the API presented by the OS into the form expected by the ported software.
