- Requirement, time, place, reason, etc are the factors that is known by owner of information for availability facility.
- Therefore, the statement is true.
Answer:
<em>The programming language is not stated;</em>
<em>However, the program written in Python is as follows</em>
def solveEquation(x,y,z):
result = z - y + 2 * x
print(result)
x = float(input("x = "))
y = float(input("y = "))
z = float(input("z = "))
print(solveEquation(x,y,z))
Explanation:
This line defines the function solveEquation
def solveEquation(x,y,z):
This line calculates the expression in the question
result = z - y + 2 * x
This line returns the result of the above expression
print(result)
The next three lines prompts user for x, y and z
x = float(input("x = "))
y = float(input("y = "))
z = float(input("z = "))
This line prints the result of the expression
print(solveEquation(x,y,z))
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>
Answer:
Quick Communication & Correspondence
Explanation:
Another main advantage of using computers in the education field is the improvement in the quality of teaching-learning process and communication between students & teachers. For this, they use Microsoft PowerPoint to prepare electronic presentations about their lectures.
