Question

(d) Which of the following is not managed by operating system?
(i) Memory usage
(i) 1/0 management
(iii) Security​

Answer 1

Answer:

Memory usage is the right answer

Answer 2

iv) None of the above

(i) Memory usage: Operating systems typically manage memory usage by allocating and deallocating memory resources for running applications. This includes managing virtual memory, swapping data in and out of memory, and ensuring that applications do not exceed the available memory limits.

(ii) 1/0 management: Input/output (I/O) operations are managed by the operating system, including reading from and writing to storage devices, network interfaces, and other peripherals. The operating system also provides mechanisms for error handling and recovery in case of I/O failures.

(iii) Security: Operating systems provide various security mechanisms, such as access controls, authentication, encryption, and firewalls, to protect the system and its users from malicious attacks and unauthorized access. However, the level of security provided by an operating system may not be sufficient in all cases, and additional security measures may need to be implemented at the application or user level.
