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>
The technological tools that can be considered important for storing critical files are battery backup systems and drives. These devices can be used to store data and supply energy.
<h3>Battery backup systems</h3>
A home battery backup system is a device used to keep the electrical system working in the event when the electrical source goes down.
In computation, there are three major classes of batteries systems: Lead-Acid, Nickel-Cadmium, and Lithium-Ion.
An uninterruptible power supply (UPS) can be considered as a battery backup supply capable of charging when the power is on.

Question
Student presentation concepts from another source
Letitia - a step-by-step process of breaking down glucose into energy
Mana - repeating process of the steps of the cell division, going from interphase to division, and back to interphase.
Paul - a series of organisms that show similar characteristics and compare them to those that do not
Which best describes the SmartArt graphic layout each student should use?
Answer:
Letitia would use a process, Maria would use a cycle, and Paul would use a relationship.
Explanation:
Letita's assignment requires her to show how glucose can be broken down into energy, this requires a series of steps in s linear fashion, meaning it would be best suited to a process-style diagram.
Marta's project involves showing the steps of the cell cycle: the clue is in the name. This process is not linear, and instead repeats itself, meaning it fits to a cycle diagram (i.e. a circular diagram)
Paul is comparing and contrasting different organisms. Therefore, he should use a relationship diagram to show shared characteristics as well as features that differ.
Explanation:
By default, SSH opens port 22.
However, this can be arbitrarily changed. So if port 22 does not work, it is necessary to check the exact/new port number.
The random number generator (data analysis tool) requires you to copy paste special value in order to create static random value(s) is a false statement.
<h3>What is the meaning of random number?</h3>
A random number is a pick of a number made seemingly at random from a certain distribution such that the distribution is reproduced when a large collection of these numbers is chosen. Such numbers must almost always be independent in order to prevent relationships between succeeding numbers.
Therefore, a hardware or software algorithm known as a random number generator produces numbers at random from a finite or infinite distribution. Pseudo-random number generators and real random number generators are the two primary varieties of random number generators.
