Across
- 5. The process that occurs when a computer is powered on and loads the operating system.
- 7. An operating system that can run only one task at a time.

- 15. An operating system designed to serve real-time applications that process data as it comes in.
- 23. (Beginner’s All-purpose Symbolic Instruction Code): A high-level programming language that was widely used for early personal computers.
- 24. Tolerance The ability of a system to continue operating in the event of a failure.
- 26. A special function that handles the event caused by an interrupt.
- 28. An early operating system for IBM-compatible personal computers.

- 35. Software that is permanently stored in a computer's hardware.
- 36. A text-based user interface used to interact with software and operating systems.
- 37. A unique identifier assigned to a process in an operating system.
- 38. The method and data structure that an operating system uses to manage files on a disk.
- 39. The use of multiple computers to provide a single service, often for the purpose of fault tolerance or load balancing.
- 41. An operating system that allows multiple users to access a single system with separate accounts.
- 43. A user interface that includes graphical elements, such as windows, icons, and buttons.
- 44. An operating system that can function independently of other systems or networks.
- 46. System: A specialized computing system that performs dedicated functions within a larger system.
- 47. A small program that loads the operating system into memory when a computer starts.
- 48. The process of verifying the identity of a user or device.
- 49. An operating system designed for end-users rather than servers.
- 50. An operating system designed to manage and provide services to multiple users over a network.
- 51. An operating system designed to be used on a wide range of devices for various types of tasks.
Down
- 1. The core part of an operating system, responsible for managing system resources.
- 2. Cluster A group of servers that share the workload, providing redundancy and improving performance.
- 3. Memory that retains its data even when the power is turned off.
- 4. A background process that performs specific functions in an operating system.
- 6. The process of disabling certain interrupts so they do not interfere with a currently running process.
- 9. Adding The ability to add hardware components to a computer while the system is running.
- 10. A diagnostic testing sequence that a computer performs to check the hardware components at startup.
- 11. An operating system that can run multiple tasks (processes) simultaneously.
- 16. ID A unique identifier assigned to a process in an operating system.
- 17. A background process that performs specific functions in an operating system.
- 18. An operating system designed for one user at a time.
- 19. An abstract indicator used to access a file or other input/output resource.
- 20. The means by which a user interacts with a computer system.
- 21. A handheld device that combines computing, telephone/fax, Internet, and networking features.
- 22. A type of system or process where the outcome is predictable and repeatable.
- 23. The initial set of instructions executed when a computer is powered on or reset.
- 25. The process by which a computer continuously checks the status of an input/output device.
- 27. Driver: A program that controls a particular type of device attached to a computer.
- 29. The capability of a system to handle a growing amount of work by adding resources.
- 30. A hardware signal sent to the CPU that temporarily stops a running program and allows a special program to run.
- 32. Swapping The process of replacing computer system components without shutting down the system.
- 34. A hardware interrupt that cannot be ignored by the processor.
- 36. The physical components of a computer system, such as the processor, memory, and storage devices.
- 37. A program in execution, which includes the program code and its activity.
- 39. (Complementary Metal Oxide Semiconductor): A technology for constructing integrated circuits, often used for the computer's memory that stores BIOS settings.
- 40. A mode of operation where the operating system has unrestricted access to all system resources.
- 42. A type of interrupt that is generated by software or a specific condition in the processor.
- 45. The process of determining if a user has permission to access a particular resource.
