Operating System Questions And Answers Quiz

Explanation
On a mainframe computer, a "bus" is equivalent to a "channel". A bus is a communication pathway that allows data to be transferred between different components of a computer system. Similarly, a channel on a mainframe computer is a high-speed pathway that connects the central processing unit (CPU) to other devices, such as storage devices or input/output devices. It facilitates the transfer of data and instructions between the CPU and these peripheral devices. Therefore, in the context of a mainframe computer, a channel is the most appropriate equivalent to a bus.

Explanation
A "protocol" refers to a set of rules that governs the behavior and communication between different entities or systems. It outlines the specific procedures, formats, and conventions that need to be followed in order to ensure smooth and standardized interactions. These rules help in establishing a common understanding and facilitate efficient and reliable communication between parties involved.

Explanation
Linux is an operating system that can be loaded and executed from a USB flash drive. This means that users can run Linux on any computer by simply plugging in the USB drive, without the need for installation or modification of the computer's existing operating system. This feature makes Linux highly portable and convenient for users who want to use their own operating system on different computers.

Explanation
Linux is the correct answer because it is an open-source operating system. Open-source refers to software that is freely available for anyone to use, modify, and distribute. Linux is developed collaboratively by a community of programmers and is known for its stability, security, and customization options. In contrast, Microsoft Windows and Mac OS are proprietary operating systems, meaning they are owned and controlled by their respective companies and their source code is not freely available.

Explanation
Linux is an open-source operating system, which means that its source code is freely available and can be modified by anyone. However, the answer states that Linux cannot modify the source code for profit. This is because the GNU General Public License (GPL), which governs Linux, requires that any modifications made to the source code must be made freely available to others. Therefore, while individuals can modify the source code for personal use or non-profit purposes, they cannot do so with the intention of making a profit from it.
