Study Notes
- Operating System (OS) is a program that manages computer hardware and provides a basis for application programs
- OS acts as an intermediary between computer users and computer hardware
- Examples of widely used Operating Systems include Windows, Linux, Ubuntu, macOS, iOS, and Android
- Computer hardware includes CPU, memory, I/O devices, and resources
- I/O devices include input devices (keyboard, mouse, microphone) and output devices (monitor, speakers)
- System Software and Application Software exist in a computer system
- System Software commands or modifies computer hardware, with OS being a type of system software
- Application Software performs specific tasks for users, such as word processors, spreadsheets, compilers, text editors, and web browsers
- Users interact with software and hardware through codes; an OS simplifies this interaction
- An OS provides a seamless and easy computing experience by managing computer hardware and acting as an intermediary between users and hardware.- The text discusses types of operating systems and their functions, as well as the goals of an operating system.
- Types of operating systems include: batch, time-sharing, distributed, network, real-time, multi-programming/multi-processing, and multi-tasking.
- Operating systems act as an interface between users and hardware, allocating resources efficiently.
- Functions of the operating system include managing memory, ensuring security, and managing input/output devices.
- Goals of the operating system are to provide convenience and efficiency.
- Convenience is achieved by making it easy for users to communicate with hardware, while efficiency is achieved by managing resources effectively.
- Most operating systems aim for both convenience and efficiency.
- The text provides an introduction to operating systems, with more detailed study to follow in the lecture series.
