The correct answer is: Scanner
The scanner is a piece of technology which unlike the printer is an input device which basically scans the top-view of any flat surface (usually paper but is definitely not limited to it) introduced in its effective range using light. The data scanned is then transfered to the Central Processing Unit for futher processing. The processed image can then be outputted and seen on the monitor's display. Once available for printing, the Central Processing Unit will just send the processed image into the printer ad voila, your scanned image is now printed in a piece of paper!
Today, scanners come with printers as a bundle. It is a perfect combination since the printer will just print the image anyway.
Answer:
A. computers will be replaced by new technology
Answer:
from socket import *
hostname = input('Enter the host to be scanned: ')
ip_add = gethostbyname(hostname)
connections = [ ]
for i in range(133, 136):
s = socket(AF_INET, SOCK_STREAM)
conn = s.connect_ex((ip_add, i))
print(conn)
connections.append(conn)
if 0 in connections:
print ('Host is online')
s.close()
else:
print ('system is unreachable')
Explanation:
The python source code above scans for all the available range of ports in the provided hostname, if any port is available, the host is online else the program print the error message "system is unreachable.
Answer:
The correct answer to the following question will be Option D (Subtractive method
).
Explanation:
- This approach essentially requests a participant to construct two activities that are already in almost every way similar, except for a mental process that is assumed to also be included in any of the activities although omitted in another.
- This method will be much more valuable when deciding the period for phonemic awareness, despite text-string identification.
The other three options are not related to the given scenario. So that Option D is the right answer.
