Study Notes
Operating System Functions
- The main function of an operating system is to manage hardware and software resources.
- Game consoles like Atari 2600 distinguish from devices with an operating system in that they lack a separate operating system, and the games are hardcoded into the firmware.
Operating System Objectives
- A key objective of operating systems is to provide a platform for running application software.
- The operating system oversees the allocation and management of system resources such as memory, CPU time, and storage.
Early Computers and Operating Systems
- The initial purpose of operating systems in the context of early computers was to manage the computer's hardware and perform tasks such as input/output operations and memory allocation.
Software Operation
- On a device without an operating system, software operates directly on the hardware, whereas on a device with an operating system, software interacts with the operating system, which then interacts with the hardware.
- The operation of software on a game console like the Atari 2600 is distinguished from a device with an operating system in that the software is hardcoded into the firmware and does not require an operating system to run.
Program Execution
- A key function of an operating system in relation to program execution is to provide a platform for running application software and manage the allocation of system resources.
Computer Resource Management
- A primary role of an operating system in managing computer resources is to allocate and manage resources such as memory, CPU time, and storage, and provide a platform for running application software.
