Paging and Segmentation are memory management techniques used by operating systems.

• Paging divides memory into fixed-size pages and stores them in physical memory.

• Segmentation divides memory into logical segments and stores them in physical memory.

• Both techniques allow for efficient use of memory and protection of memory from unauthorized access.

• Examples of operating systems that use paging and segmentation include Wind

Run time mapping between pages and frames is the process of mapping virtual memory pages to physical memory frames during program execution.

• During program execution, the operating system maps virtual memory pages to physical memory frames to ensure efficient memory management.

• This mapping is done dynamically and can change as the program runs.

• The mapping is maintained in a page table, which is used by the operating sys...read more

Critical section is a part of code that must not be executed by more than one thread at a time.

• It is used in multi-threaded programming to avoid race conditions.

• It is usually protected by locks or semaphores.

• Examples include updating shared variables or accessing shared resources.

• It is important for ensuring data consistency and preventing deadlocks.

Code for critical section in C/Java/C++

• Use mutex or semaphore to protect critical section

• In C/C++, use pthread_mutex_lock() and pthread_mutex_unlock()

• In Java, use synchronized keyword

• In C++, use std::mutex and std::lock_guard

• Ensure only one thread can access critical section at a time

Explanation of how sorting and searching complexities are derived.

• Sorting and searching algorithms have different complexities depending on the algorithm used.

• Sorting algorithms can be classified as O(n^2) or O(n log n) depending on the algorithm used.

• Searching algorithms can be classified as O(n) or O(log n) depending on the algorithm used.

• Complexities are derived by analyzing the number of operations required to comp...read more

An abstract class is a class that cannot be instantiated and is used as a base class for other classes.

• An abstract class can have abstract and non-abstract methods.

• Abstract methods have no implementation and must be implemented by the derived classes.

• An abstract class can have constructors and fields.

• An example of an abstract class is the Shape class, where the methods like area() and perimeter() are abstract and must ...read more
