Description
The operating system acts as an Interface between the user and computer hardware, OS is designed in such a way, that it is convenient to use in an efficient manner. Tasks performed by Operating System are It manages computer hardware, It controls and coordinates the computer H/W and specifies, how various resources like hardware and software can be used in an efficient manner. Users want ease of use and good performance & highly convenience. Users can share the terminals, connected to mainframe or minicomputer. Individual Users with dedicate systems such as workstations use shared resources from servers or Printers. In case of hand held devices, the operating system is designed for individual usability. Example: OS on iPhone, or any Android phone. OS is a resource allocatorManages all resourcesConflicting requests between resources are managed for efficient use◦OS is a control programControls execution of programs to prevent errors and improper use of the computerObjectives of Operating systemConvenienceEfficiencyAbility to evolveIt specifies how resources are convenient to use in an efficient manner.OS as a service routine1.Program development.Ex: Editors & Debuggers1.Program Execution2.Access I/O devices and controlling access to I/O devices3.Error detection & response4.Performance maintenance
