Functions of an Operating System

Operating systems (OS) = Manage hardware resources and provide a user interface Device drivers = Enable communication between hardware and OS Firmware = Control a device's basic functions Utility software = Tools for system maintenance and optimization

Boot loaders = Initialize the OS during startup System software = Intermediary between hardware and users Application software = Runs on the platform provided by system software Low-level languages = Interact with hardware at a basic level

Manage hardware resources = Allocate memory, CPU time, and peripheral devices efficiently Provide a user interface = Offer an environment for users to interact with the computer Optimize system performance = Enhance the efficiency and speed of system operations Handle errors and security = Ensure system stability and protect against threats

<p>Prevents unauthorized access to programs and data using passwords = Security Production of dumps, traces, error messages, and other debugging methods = Error-detecting Aids Detect and handle errors during program execution = Error-detecting Aids Improve overall efficiency and speed of the computer system = Optimize system performance</p> Signup and view all the answers

<p>Software applications designed for system management and control = System programs Developed using specialized programming languages and techniques = System programming Categorized as system software, e.g., compilers and operating systems = System programs Perform specific tasks related to system management and control = System programs</p> Signup and view all the answers

<p>Operating system performs file management = File Management Deciding resource allocation and de-allocation = File Management Handles file operations such as read/write = File Management Manages how resources are allocated among users or processes = File Management</p> Signup and view all the answers

<p>Provides services needed by application programs to run = Support application software Includes file management and memory operations = Support application software Handles input/output operations for applications = Support application software Optimizes system performance for running application programs = Support application software</p> Signup and view all the answers

<p>Improve overall efficiency and speed of the computer system = Optimize system performance Allocate resources efficiently for better performance = Optimize system performance Enhance memory management for faster processing = Optimize system performance Schedule processes effectively through algorithms = Optimize system performance</p> Signup and view all the answers
