1. An aplications software package does not communicate directly with the hardware, whereas an operating system is a set of programs that lies between applications software and the computer hardware.
2. The supervisor program is the most important operating system program because it controls the entire operating system and loads into memory other operating system programs from disk storage only as needed.
3. A resident program is the program most of which remains in memory, whereas a non-resident program is the program which is loaded into memory.
4. An operating system has three main functions: (1) manage the computer's resources, such as the central processing unit, memory, disk drives, and printers, (2) establish a user interface, and (3) execute and provide services for applications software.
1. The main difference between application software and operating system is that an operating system works as the interface between the user and the hardware while the application software is a program that performs a specific task.
2. Because the supervisor controls the entire operating system and loads into memory other operating system programs from disk only as needed.
3. The resident (supervisor program) remains in memory. The supervisor controls the entire operating system and loads into memory other operating system programs (called nonresident) from disk storage only as needed.
4. An operating system has 3 main functions:
1) manage the computer's resources
2) establish a user interface
3) execute and provide services for applicatiions software.
