Study Notes
Operating System (OS) Overview
- Acts as an intermediary between a user and computer hardware
- Goals: execute user programs, make problem-solving easier, provide convenient computer use, and efficient hardware utilization
Computer System Components
- Hardware: basic computing resources (CPU, memory, I/O devices)
- Operating System: controls and coordinates hardware use among applications and users
- Application Programs: define system resource use to solve user computing problems
- Users: people, machines, or other computers
Operating System Definition
- No universally accepted definition
- Approximation: "everything a vendor ships when you order an operating system"
- Kernel: the one program running at all times on the computer, part of the operating system
Operating System Components
- Kernel: part of the operating system
- System Programs: ship with the operating system, but not part of the kernel
- Application Programs: all programs not associated with the operating system
- Middleware: software frameworks providing services to application developers (databases, multimedia, graphics), included in today’s OSes for general purpose and mobile computing
