LINUX OPERATING SYSTEM
Section 1
Answer 1:
The five most vital services of the Operating System are:
1. Program Execution: The Operating System helps the users and the user-level
applications, with a platform to perform several operations and tasks. The OS
translates and executes the programs and data in a meaningful way by utilizing every
possible resources.
2. Resource allocation: Resource allocation is one of the most important tasks of the
Operating System. Through this process, the OS assigns and manages computational
assets in such a manner, which supports a program or process’s requirement or
performance goals. It includes utilizing the processor resources and other tangible
properties to provide the application software with a hasty and comfortable working
environment.
3. Protection: For computer systems with more than one users and concurrent execution
of multiple or multi-level processes, it is necessary for these processes to be
abstracted from the activities of each other [5].
4. Error Detection and Handling: Errors or Exceptions can occur at any time during the
session of an OS or during the execution of a process. Errors may occur in the CPU,
in memory devices or in the I/O devices. The major activities of the OS in error
handling are as follows:
 The OS keeps constant track of error occurrences at real time.
 The OS takes all needed actions to handle these errors to protect its ongoing
processes from crashing [1].
