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
