How many distinct categories of operating systems exist?
Operating systems can be classified into four main categories based on their functionality and design principles. These categories are: Real-time operating systems: Designed for tasks requiring immediate and predictable response times. Single-user single-task operating systems: Handle one task at a time for a single user. Single-user multi-tasking operating systems: Allow a single user to work on multiple tasks simultaneously. Multi-user operating systems: Support multiple users working concurrently on the same system.
Which of the following is not included in a graphical user interface (GUI)?
The correct answer is command prompt. Among the options listed, the "command prompt" is not a component typically found within a graphical user interface (GUI). It refers to a text-based interface used for entering commands directly into the operating system, contrasting with the visual and interactive elements commonly associated with GUI environments.
__________ a collection of software consisting of instructions that collaborate to manage and orchestrate all interactions among computer hardware components.
The correct answer is Operating system. An operating system is indeed a collection of software that comprises a set of instructions working in collaboration to manage and oversee all interactions and operations among the various hardware components within a computer. It provides essential functionalities like memory management, task scheduling, file management, and hardware communication.
What category do icons, menus, and windows belong to?
The correct answer is Graphical user interface (GUI). Icons, menus, and windows are elements that belong to the category of graphical user interface. GUI provides users with a visual way to interact with a computer's operating system and applications, utilizing icons for quick navigation, menus for accessing commands, and windows for managing multiple tasks and application instances.
Which of the following is not a role performed by an operating system?
The correct answer is Checking for viruses. Among the options provided, the function of checking for viruses is not typically a direct role performed by the operating system. While operating systems may offer basic security features, dedicated antivirus software is more commonly responsible for detecting and preventing viruses on a computer.
_____________are software applications developed to assist users in enhancing their efficiency when performing personal tasks.
The correct answer is Application software. Application software refers to software programs that are designed to aid users in improving their productivity and effectiveness while carrying out personal tasks. These programs provide specific functionalities tailored to tasks such as word processing, spreadsheet management, multimedia editing, and more.
What does the term "defragmentation" refer to?
The correct answer is Rearranging files to occupy contiguous space. Defragmentation pertains to the process of rearranging files on a storage device such as a hard drive, so that they are placed in contiguous blocks of space. This practice aims to optimize read and write operations, enhancing the overall efficiency and speed of data access on the storage device.
The role of system software is to act as the __________ connecting the user, the application software, and the hardware of the computer.
The correct answer is interface. System software functions as an interface, serving as a bridge or intermediary that facilitates communication and interaction between the user, application software, and the underlying hardware components of the computer. It provides a layer of abstraction that simplifies the interaction between different layers of the computing environment.
What is the term for an operating system that is stored on a ROM chip within a mobile device or consumer electronic device?
The correct answer is Mobile OS. A Mobile OS is the term used to describe an operating system that is stored on a ROM chip within mobile devices or consumer electronic devices. These operating systems are specifically designed to manage and control the functionalities of mobile devices, ensuring efficient and optimized performance.
The act of rebooting a computer or mobile device while it is still powered on.
The correct answer is Warm boot. A warm boot refers to the process of restarting a computer or mobile device while it remains powered on. During a warm boot, the system reloads the operating system and essential software components without fully powering off. This type of reboot is often used to resolve minor issues or to refresh the system without the need to go through the entire startup process.
