Answer:
Top down design
Explanation:
Top-down design is an approach that is used to break down the problem into the smaller subpart so that it can be manageable into more clear form.
C programming is the example of a top-down approach while C++ is the example of the bottom-up approach.
The advantages of the top-down design approach are:
1) easy to manage
2) easy to find the error
3) easy to debug
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.
