| Front | Back |
| Define kernel in an operating system | The core component of an OS that manages system resources and coordinates hardware and software communication |
| Explain multitasking in operating systems | The ability of an OS to execute multiple processes concurrently by managing CPU time and resource sharing |
| How do operating systems ensure system security | By enforcing user authentication, access controls, encryption and regular updates to protect against vulnerabilities |
| How do operating systems manage hardware through device drivers | They use device drivers to enable communication between the OS and hardware ensuring proper functionality |
| How does a file system contribute to an operating system? | It organizes, stores, retrieves, and manages data on storage devices |
| In what ways do operating systems facilitate network connectivity | They provide networking protocols, tools and services for managing connectivity, data transfer and network resources |
| Name three primary functions of an operating system | Memory management; process scheduling; and file system management |
| What are drivers in operating systems | Specialized software that allows the OS to communicate effectively with hardware devices |
| What are some common types of operating systems? | Desktop, server, mobile, embedded, and real-time operating systems |
| What does memory management do in an operating system? | It allocates and deallocates memory to various programs and processes for efficient execution |
| What does regular maintenance of an operating system include? | Routine updates, patch management, performance monitoring, and security audits |
| What is a boot loader's role in an operating system | A small program that initializes system hardware and loads the OS kernel during startup |
| What is a command line interface (CLI) in an operating system | A text based interface that allows users to interact with the system by entering commands to execute functions |
| What is a graphical user interface (GUI) in operating systems | A visual based interface that uses icons, windows and menus to facilitate user interaction with the system |
| What is an operating system? | Software that manages computer hardware and software resources and provides services for programs |
| What is process management in an operating system? | The component responsible for creating, scheduling, and terminating processes |
| What is virtualization in operating systems | The process of creating virtual instances of physical components to allow running multiple virtual OS environments on a single hardware system |
| What steps are involved in operating system installation and configuration? | Installing the OS, setting up user accounts, configuring hardware drivers, and applying updates |
