Document Summary
Computer system can be divided into four components. Cpu, memory, i/o devices, graphics card, storage. Controls and coordinates use of hardware among various applications and users to solve computing problems of users. Application programs: define how the system resources are used. A program that acts as an intermediary between a user of a computer and the computer hardware. Shared computers must keep all users happy. Users of workstations often have dedicated resources but also use resources from servers. Handheld computers are optimized for battery life and usability / resource poor. Some computers have no user interface, such as embedded computers in electronic devices and cars: os definition. Os kernel: the one program running at all times on the computer. Everything else is either a system application or application program: computer system organization. One or more cpu"s, device controllers connect common bus providing access to system memory: computer startup. Typically stored in rom or eprom, generally known as firmware.
