Answer:
b. Rubato tremolo
Explanation:
Tremolo is a modulation effect that imposes a rhythmic change in volume of sound. Once discovered in electric amplifier circuits, sound engineers and composers like the Baroque now use this low frequency oscillating modulation technique to create emotional piercing effect on their audience to maintain focus.
The low frequency tremolo can be gotten from the vibrating string in guitars, violins etc, and vocal sound, it is also produced from electronic devices created for its purpose. they are called optical tremolo.
Answer:
4. Command line interface (CLI)
Explanation:
An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.
This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.
Some examples of an operating system on computers are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM etc.
A Command line interface (CLI) refers to a text-based user interface that allow users to operate a software application or program, as well as manage and execute operating system functions by typing standard line of commands into the text-based user interface with a real-time response.
Basically, the CLI is solely text-based and as such requires a thorough knowledge and understanding of global commands, as well as administrative privileges in some cases.
<em>Hence, the operating system function which has a steeper learning curve (more difficult to learn) and can potentially break the system without careful use of its operations is the Command line interface (CLI). </em>
