class MagicSquare():
def __init__(self,side):
self.side=side
self.two_dimension=[]
for row in range(1,side+1):
row_line=[]
for col in range(1,side+1):
row_line.append(0)
self.two_dimension.append(row_line)
def display(self):
row=0
col=int((self.side-1)/2)
for i in range(1,self.side**2+1):
self.two_dimension[row][col]=i
row-=1
col+=1
if row==-1:
row=self.side-1
if col==self.side:
col=0
if self.two_dimension[row][col]==0:
continue
else:
row+=1
if row==self.side:
row==0
for line in self.two_dimension:
for num in line:
print("{0:>3}".format(num),end=" ")
print()

The best description of a computer virus is. Someone first starts out making a malicious program, then can send it to a unexpected user. After that, when the user opens the malicious program, it can do negative things on the target. The virus first starts out in the system32, then infects a random file type for example, exe files, or dlls etc. Then random errors can pop up on the computer saying "YOUR COMPUTER IS UNDER RISK! CALL THIS NUMBER NOW! 555-555-5555" and the options of the error, can direct you to a website, that can give you another virus. To get rid of a virus, you have to ignore the popups that comes onto your computer, and get a strong antivirus like avast, or avg. Then let it scan the system. After when the scan is done, it will show up the virus, and it will give you options "to delete virus or ignore it" you would hit delete. I hope this answer helped you. Let me know if you have any more questions! Thanks!

Answer
The senders PC is using UDP protocol
Explanation
UDP is the User Datagram Protocol which is used as an alternative communication protocol to the TCP which is used primarily for establishing low latency and loss of tolerating connections between applications on the internet UDP is normally used by the programs running on different computers on a network. Its purposes is to send short messages which are datagrams. It is not much reliable because of its occasional loss of packet. Due to this packet loss the recipient is not guaranteed that the data being streamed will not get interrupted. This is because If a router on the Internet starts getting overloaded, or a packet gets corrupted due to interference or anything, the packet will be dropped unlike the TCP (Transmission control protocol)which resend the packets and keeps re sending. The UDP does not resend the packets which are dropped. Once they are dropped that all.
