Computer: OS Vocabulary Worksheet

Explanation
The operating system is responsible for managing and controlling the hardware components of a computer, including the CPU. It acts as an interface between the user and the computer, allowing them to interact with the hardware and run applications. The BIOS (Basic Input/Output System) is a firmware that initializes the hardware during the boot-up process, but it does not directly control the CPU's communication with other components. DOS (Disk Operating System) is an older operating system that primarily manages disk operations. Graphics, on the other hand, refers to the visual display on the computer and is not directly related to the CPU's communication with other hardware components.

Explanation
The correct answer is "user friendly" because it refers to a computer that is easy to operate. This term is commonly used to describe software or hardware that has a simple and intuitive interface, making it accessible and understandable for users with varying levels of technical expertise. It implies that the computer system is designed with the user's convenience and ease of use in mind, allowing for a smoother and more enjoyable user experience.

Explanation
The BIOS (Basic Input/Output System) is responsible for waking up the computer and reminding it what to do. It is a firmware that is stored on a chip on the motherboard. When the computer is turned on, the BIOS initializes and performs a series of tests to ensure that all hardware components are functioning correctly. It then loads the operating system into memory and hands over control to it. In this way, the BIOS acts as a mediator between the hardware and the operating system, providing essential instructions for the computer's startup process.

Explanation
The essential part of the operating system is stored on ROM because it contains the fundamental instructions and functions required for the system to boot up and perform basic operations. This part is crucial for the system to function properly and cannot be modified or upgraded by the user. Storing it on ROM ensures that it remains intact and accessible every time the system is powered on.

Explanation
The correct answer is "Hard Drive" because the important, but non-essential, parts of the operating system are typically stored on the computer's hard drive. The hard drive is a non-volatile storage device that allows the operating system to be installed and run on the computer. It stores the necessary files and data for the operating system to function properly, including system files, drivers, and software applications. Without a hard drive, the operating system would not be able to load and run on the computer.

Explanation
Disk-based Operating System (DOS) is the correct answer because it was one of the earliest and most widely used operating systems for personal computers. It was developed by Microsoft and was commonly used in the 1980s and 1990s. DOS allowed users to interact with their computer through a command-line interface, and it was primarily used for running applications and managing files on disk storage. Although it has been largely replaced by more advanced operating systems like Windows, the term DOS is still used to refer to this type of operating system.

Explanation
Windows is the most common operating system for PCs because it is widely used and has a large market share. It is developed by Microsoft and offers a user-friendly interface, a wide range of software compatibility, and regular updates and support. Windows has become the standard operating system for many businesses and individuals due to its ease of use, extensive software library, and compatibility with a variety of hardware devices.

Explanation
As technology advances, operating systems need to be upgraded in order to keep up with the latest advancements and to ensure compatibility with new hardware and software. Upgrades are necessary to improve performance, enhance security, fix bugs, and introduce new features that can enhance the user experience. Therefore, the correct answer is "upgraded".

Explanation
System 8 is an example of a Macintosh operating system. Macintosh operating systems are specifically designed for Apple Macintosh computers. System 8 was released by Apple in 1997 and was the eighth major release of the Mac OS. It introduced several new features and improvements, including a redesigned interface, enhanced networking capabilities, and improved performance. System 8 was a significant upgrade from previous versions and was well-received by Mac users at the time.

Explanation
A Graphical User Interface uses graphics to help the user navigate within the computer system. Graphics, such as icons, menus, and buttons, provide visual representations of different functions and options available to the user. These graphical elements make the interface more intuitive and user-friendly, allowing users to interact with the system by simply clicking or tapping on the visual elements rather than typing commands or codes. Therefore, graphics play an essential role in facilitating user navigation within a Graphical User Interface.
