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])
Answer:
The answer is "Option A".
Explanation:
The Dot matrix printer is also known as an impact matrix printer. It is a multi-part form printer because it prints data on paper. This printer uses a hammer and a ribbon printer, that shapes pictures from dots. and other options are not correct, that can be described as follows:
- In option B, daisy-wheel printer prints data on printer only one side that's it is not correct.
- In option C, the Inkjet printer is capable to print data in multi-part forms, but this printer does not data in continuous forms.
- In option D, the color printer allows you to print data in color format like images, graphs, and banner. It prints data only on one side, that's why it is not correct.
Answer: D
Explanation:
It is not A or C because the "d" in "Divide" is capitalized and the d is lowercase in calling the function. Therefore the answer is D (the last choice) because numA / numB (30 / 5) equals 6.
The answer is firewall. It is a network security device that observes inbound and outbound network traffic and chooses whether to allow or block specific traffic based on a well-defined set of security rules. Firewalls have been a first line of protection in network security for over 25 years. The firewall present a barrier between measured and secured internal networks that can be trusted and untrusted outside networks, for example the Internet. A firewall can be software, hardware, or even both.
