Q

Have a simple thread of control and can execute only one instruction at a time.

Study These Flashcards
A

Single-threaded processes

24
Q

Have multiple threads of execution, allowing them to perform multiple tasks concurrently within the same process

Study These Flashcards
A

Multi-threaded processes

25
Created by an existing process (parent process) through system calls like fork() or spawn(). They share some resources with the parent but have their own address space.
Child processes
26
Child processes whose parent process terminates before them. The operating system usually adopts them as its child.
Orphan Processes
27
Interact directly with the user and require immediate response.
Foreground processes
28
Run independently of user interaction and often perform tasks like system maintenance, printing, or network services
Background processes
29
Require strict deadlines and have high priority to ensure timely execution
Real-time processes
30
Do not have strict deadlines and can tolerate delays.
Non-real-time processes
31
a crucial function of an operating system that handles the allocation and deallocation of primary memory (RAM) among various processes
Memory Management
32
Maximizes the use of available memory by allocating it to processes as needed.
Efficient Utilization
33
prevents processes from accessing memory regions allocated to others, ensuring data integrity and system stability
Protection
34
Provides a simplified view of memory to processes, allowing developers to focus on their tasks without worrying about physical memory details
Abstraction
35
Enables multiple processes to share memory regions when necessary, improving resource utilization
Sharing
36
Dividing memory into smaller units for allocation to processes
Memory Partitioning
37
Temporarily moving processes from main memory to secondary storage (disk) when memory is full and bringing them back when needed
Swapping
38
creating illusion of larger memory space by using disk storage as an extension of main memory
Virtual Memory
39
Dividing both physical and virtual memory into fixed-size blocks (pages and frames) for efficient management
Paging
40
administration approach used in operating systems that divides memory into multiple-sized segments
Segmentation
41
is an operating system which first came out in 1981 and was designed to run on PC compatible computers
MS-DOS(Microsoft Disk Operating System)
