On a mainframe computer, what is the equivalent of a "bus"?

Bus
Channel
Car
Stream

Correct Answer

A. Channel

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.

Which of the following is/are true of Linux?

Cannot be installed on a Windows computer
Cannot be installed on a Macbook
Cannot modify the source code for profit
Cannot use Mozilla Firefox

Correct Answer

A. Cannot modify the source code for profit

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.
