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.
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).
Why do the spelling and grammar checkers in Word miss some errors?
Answer must include 3-5 sentences
Answer:
Word dose not always catch misspellings why? Its because its a computer program. the program has to run through algorithms (millions a second) and that makes a large margin for error. it could also be the fact that the misspelling is very uncommon so it dose not recognize it.

Which lines of code will assign the discriminant the value b2−4ac? Select 2 options.
discriminant = bb - 4ac
discriminant = b * b - 4 * a * c
discriminant = b ^ 2 - 4ac
discriminant = b ** 2 - 4 * a * c
discriminant = b ^ 2 - 4 * a * c
Answer:
discriminant = b * b - 4 * a * c
discriminant = b ** 2 - 4 * a * c
Explanation:
The operands are correct and in the right order (for python).
** is the operand for squaring something.
* is the operand for multiplying something.
- is the operand for subtracting something.
Let's take a look at these examples individually.
discriminant = bb - 4ac. You have to use the * sign so the computer understands that you're trying to multiply two objects together.
discriminant = b * b - 4 * a * c. This example works because it's using the * where it's appropriate.
discriminant = b ^ 2 - 4ac. In python we don't use the ^ sign. To use exponents, we use **. Also, there is no * sign in between 4, a, and c.
discriminant = b ** 2 - 4 * a * c. This example works because it uses the ** and * sign where appropriate.
discriminant = b ^ 2 - 4 * a * c. This example uses the ^ sign and python does not support it.
Help, please! I will mark as brainliest
Answer:
Change line 7 to:
for( int i=0; i < names.length; i++)
Last element in the array is one less than the length, ie:
stArr1.length - 1
To print every other value, you replace index++ with index += 2
Explanation:
Not only should you change the <= into <, but also i should start at 0, not 1. The first element of an array has index 0.

How do you skip the drawing steps in turtle graphics and just get the result? Thank you.
Answer:
Turtle graphics is a popular way for introducing programming to kids. It was part of the original Logo programming language developed by Wally Feurzig and Seymour Papert in 1966.
Imagine a robotic turtle starting at (0, 0) in the x-y plane. Give it the command turtle.forward(15), and it moves (on-screen!) 15 pixels in the direction it is facing, drawing a line as it moves. Give it the command turtle.left(25), and it rotates in-place 25 degrees clockwise.
By combining together these and similar commands, intricate shapes and pictures can easily be drawn.
The turtle module is an extended reimplementation of the same-named module from the Python standard distribution up to version Python 2.5.
It tries to keep the merits of the old turtle module and to be (nearly) 100% compatible with it. This means in the first place to enable the learning programmer to use all the commands, classes and methods interactively when using the module from within IDLE run with the -n switch.
The turtle module provides turtle graphics primitives, in both object-oriented and procedure-oriented ways. Because it uses tkinter for the underlying graphics, it needs a version of Python installed with Tk support.
The object-oriented interface uses essentially two+two classes:
The TurtleScreen class defines graphics windows as a playground for the drawing turtles. Its constructor needs a tkinter.Canvas or a ScrolledCanvas as argument. It should be used when turtle is used as part of some application.
The function Screen() returns a singleton object of a TurtleScreen subclass. This function should be used when turtle is used as a standalone tool for doing graphics. As a singleton object, inheriting from its class is not possible.
All methods of TurtleScreen/Screen also exist as functions, i.e. as part of the procedure-oriented interface.
RawTurtle (alias: RawPen) defines Turtle objects which draw on a TurtleScreen. Its constructor needs a Canvas, ScrolledCanvas or TurtleScreen as argument, so the RawTurtle objects know where to draw.
Derived from RawTurtle is the subclass Turtle (alias: Pen), which draws on “the” Screen instance which is automatically created, if not already present.
All methods of RawTurtle/Turtle also exist as functions, i.e. part of the procedure-oriented interface.
The procedural interface provides functions which are derived from the methods of the classes Screen and Turtle. They have the same names as the corresponding methods. A screen object is automatically created whenever a function derived from a Screen method is called. An (unnamed) turtle object is automatically created whenever any of the functions derived from a Turtle method is called.
To use multiple turtles on a screen one has to use the object-oriented interface.
Note In the following documentation the argument list for functions is given. Methods, of course, have the additional first argument self which is omitted here.

Explanation:
The position of a runner in a race is a type of analog data. The runner’s position is tracked using sensors. Which of the following best describes how the position of the runner is represented digitally?
A
The position of the runner is determined by calculating the time difference between the start and the end of the race and making an estimation based on the runner’s average speed.
B
The position of the runner is measured and rounded to either 0 or 1 depending on whether the runner is closer to the starting line or closer to the finish line.
C
The position of the runner is predicted using a model based on performance data captured from previous races.
D
The position of the runner is sampled at regular intervals to approximate the real-word position, and a sequence of bits is used to represent each sample.
Answer:
D. The position of the runner is sampled at regular intervals to approximate the real-word position, and a sequence of bits is used to represent each sample.
Explanation:
C was wrong for me :(
Introduction:
The runner position is detected by sensors in a race. It is very difficult to keep track of every racer position manually therefore computer program are used to keep exact recordings.
Explanation:
The data is sometimes recorded manually and is in analog form which is converted in to digital form.
Conclusion:
The correct answer is D. The position of the runner is sampled at regular intervals to approximate the real-word position, and a sequence of bits is used to represent each sample.

If you need to modify a features in a part created using the Mirror tool, you can make the change in the original feature and the feature on the other side of the mirror plane will be modified automatically.
Select Answer
False
True
Answer:
The answer to this question is given below in the explanation section.
Explanation:
The correct answer to this question is TRUE.
Because when you are designing something and drawing anything and it is symmetric in shape and half of the part is created, then if you use mirror features, then the other half part will get created automatically.
If you need to modify the features in the original part of the drawing or design then the other side of the mirror plane will be modified automatically.
Because whatever you will make changes in the original part of the design, then the other part that is created by using mirror features will get modified automatically.
