When you established social links, your social media site profile may eliminate almost any generic symbol throughout the list of contacts and the Individuals Pane with profile pic the contact may have placed. Thus, the Users Pane would be exchanged with profile image of the contact while establishing the social connections.
Answer:
In Python:
import os.path
from os import path
fname = input("Filename: ")
if path.exists(fname):
with open(fname) as file_in:
lines = []
for line in file_in:
lines.append(line.rstrip('\n'))
f = open("stat.txt","r+")
f.truncate(0)
f = open("stat.txt", "a")
f.write("Names\tTotal\tSubjects\tAverage\n")
for i in range(len(lines)):
rowsum = 0; count = 0
nm = lines[i].split()
for j in nm:
if (j.isdecimal()):
count+=1
rowsum+=int(j)
average = rowsum/count
f.write(nm[0]+"\t %3d\t %2d\t\t %.2f\n" % (rowsum, count, average))
f.close()
else:
print("File does not exist")

Explanation: Functional requirement is the requirement in the operating system that gives the description of the functioning and specific action that is done by system.
Thus, receiving the data rapidly is not the form of functional requirement as it does not specifies any function that is to be done and receiving of data is already being done and at faster rate in future.
Performance requirement is the factor that is required for defining that how well a system should perform the function.So, reviving data at rapid rate is performance requirement.So, the statement given is false.
