What are Program threats in operating systems?
Program threats in operating systems refer to vulnerabilities that can be exploited by malicious actors to compromise the integrity, confidentiality, or availability of software applications. Common examples include buffer overflow attacks, where excess data overwrites memory, and code injection attacks, where harmful code is inserted to manipulate program execution. These threats can lead to unauthorized access, data breaches, and service disruptions, necessitating robust security measures to mitigate risks. Effective programming practices and regular updates are essential to protect against such threats.

1. List five services provided by an operating system. Explain how each provides convenience to the users. Explain also in which cases it would be impossible for user-level programs to provide these services.
Answer:
1. Program execution - the operating system will schedule on behalf of the user. This service could not be handled by the user because you need access to the hardware.
2. I/O operations - This makes it easy for users to access I/O streams. This means the user does not need to know the physical access of data in the machine. If there were not interface provided the user could not do this on their own.
3. File-system manipulation - This means the user does not need to worry about accessing and updating the file system table. Such access is best handled by the operating system because of this complexity.
4. Communications - in the case of memory mapping this is extremely beneficial for the OS to handle access and control to memory regions. The user could not in this case access such a system to share the map.
5. Error detection - If there is some error on one of the lower levels the user is notified so that they can take action. If there is no memory left on the heap for instance. The user could not do this because it is simply too much work for the user.
What is time sharing operating system?
Time-sharing is sharing a computing resource among many users by means of multiprogramming and multi-tasking. Its introduction in the 1960s, and emergence as the prominent model of computing in the 1970s, represents a major technological shift in the history of computing. By allowing a large number of users to interact concurrently with a single computer, time-sharing dramatically lowered the cost of providing computing capability, made it possible for individuals and organizations to use a computer without owning one, and promoted the interactive use of computers and the development of new interactive applications.

What are the characteristics of effective 360 degree feedback systems?
First, effective 360 feedback systems should be linked to an organization's leadership competency model. In turn, this competency model should be linked to the organization's mission, vision, and strategy. In this way you can ensure the leader behaviors you are reinforcing are linked to the success of your organization. Second, 360 feedback should be used for developmental purposes only. If you use 360 feedback for evaluative purposes, people may game the system by giving their friends high ratings in return for high ratings from their friends, or people may be incentivized to give their peers low ratings to look better by comparison. Third, 360 feedback should be coupled with action planning, coaching, and training to support those leaders going through the program. Nothing is more demoralizing than getting feedback that you need to improve upon a skill and having no idea how to go about developing that skill, so leaders should be provided with ample support once they have received their feedback report. Finally, be sure to be open and honest when designing and communicating the purpose of the program. Participation from all ranks in the organization during the planning phase will not only increase buy in and participation in the program, it will increase the quality of the tool as well.
