Answer:
See explaination
Explanation:
Please check below for the code for first_word.py file which will print first word of an input file stuff.txt. So the open function will open file in read mode. We had maintained a count variable so that we can skip printing first word of first line. Also the command line.strip() checks whether string is empty or not so that we will not get index error while calling split function over line to get first word.
#!/usr/local/bin/python
stuff = open("stuff.txt", "r");
count = 0;
for line in stuff:
count+=1;
if (count>1 and line.strip()):
print(line.split(maxsplit=1)[0])
From the code you posted, there is no function call to vendingMachine()
Try at the top of your code:
print ("hello")
vendingMachine()
def vendingMachine():

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 engineer will need to set the distance to 130 for the static link so that it becomes a floating static route.
<h3>What is Floating static routes?</h3>
This is known to be a static routes that is said to have a kind of administrative distance that is also known to be bigger than the administrative distance of any other static route or dynamic routes.
Note that the value 130 stands for the next most logical value, nd as such it is to know that the right route comes first in the steps for administrative distance.
