Study Notes

Operating System Role

The operating system mediates between the user, applications, and the computer's hardware.
Primary duties include managing the hardware, providing an environment for applications, and facilitating user interaction.
Operating systems serve various needs - some prioritize efficiency while others optimize user convenience.

System Components

A computer system is a combination of hardware, operating system, application programs, and users.
The hardware comprises the CPU, memory, and input/output (I/O) devices.
Application programs utilize these resources to fulfill user tasks.
The operating system acts as a controller, managing the hardware and mediating resource use among various application programs and multiple users.

User Perspectives

Users interact with the operating system differently depending on the interface.
For a single user PC system, ease of use is prioritized over resource utilization.
Users sharing resources on mainframes or minicomputers require operating systems that prioritize efficient resource utilization.
Workstations necessitate operating systems that balance individual usability and resource management, as users share resources like networks and servers.
Mobile computers like smartphones and tablets emphasize user experience and mobile connectivity, often replacing desktop and laptop computers for everyday use.
