Question

briefly discuss the key issue or issues that an OS must address: • cloud computing • mobile computing • real-time embedded systems.

Answer 1

Cloud Computing:

1. Security Issues: Cloud computing security is a major topic for concern. Continuously there are many data breaches as well as password thefts. Also we don't know about the system where our data is being stored.
2. Performance: The performance of the application as well as CPU sometimes is greatly affected while using cloud based applications. OS must recognize this.

Mobile Computing:

1. Security Issues: In mobile computing user is connected to public networks. Public networks are more vulnerable to attackers and mobile system can easily be hacked by someone.
2. Network Issue: In some areas the bandwidth is not good enough to provide a proper connection.

Real-time Embedded Systems:

1. Consistency: Real time systems are not consistent every time. Every OS must check on this.
2. Performance: The performance of real-time embedded systems decrease with time. Whenever there is an issue the OS should notify about this.
