One advantage of Binary Search Algorithm:
Compared to Linear search it is much faster because linear search starts its searching right from the first value but binary searches for something by splitting the array in two again and again and again.
One disadvantage of Binary Search Algorithm:
Have to be sorted, unlike linear search that doesn't have to be.
Computer Chips. / SILICON. This is just an educated guess
The answer is Multitasking. NOS (Network Operating System) has the ability to execute more than one program at a time. It allows different programs to operate on the CPU, effectively giving each program a virtual copy of the CPU while preventing the program from directly manipulating the hardware. The NOS switches the CPU time from one task to another in order to create the idea that several tasks are being executed at the same time, but in reality, only one program is being executed.
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.
