Answer: In operating system a code segment which accesses some shared variables or resources one at a time atomically such other no other code or process is accessing that resource or variable at the same time.
Entry section code block allows the access to the shared resource or variable and exit section code signals the termination from access to the shared resource or variable.
Explanation:
Entry and exit section codes needs to check certain properties before allowing the access and removal of access to a particular code segment.
These conditions are:
1. Bounded waiting.
2. Mutual exclusion.
3. checking thread execution status to allows other threads to enter the critical section (CS).
Answer:
Option C. The path from start to finish that passes through all the tasks that are critical to completing the project in the shortest amount of time
is the correct answer.
Explanation:
- Critical path is the term used in Project management.
- It can be known by determining the longest stretch for dependent activities and the time required for them to complete.
- A method known as "critical path method" is used for Project modelling.
- All types of projects including aerospace, software projects, engineering or plant maintenance need Critical method analysis for the modeling of project and estimation.
