Answer:
D. ARPANET was developed
Explanation:
ARPANET is an acronym for Advanced Research Projects Agency Network and it was established in 1969 by the Advanced Research Projects Agency (ARPA) of the United States Department of Defense.
ARPANET was the first wide area packet switching network for transmitting electronic data and communications between computers on a single network with a distribution functionality. The TCP/IP protocol was first implemented on the Advanced Research Projects Agency Network (ARPANET), as well as some other standard protocols such as the NCP and the 1822 protocol.
The development of ARPANET happened first in the evolution of the internet.
E-mail is an acronym for electronic mail and it was invented by Ray Tomlinson in 1971; World Wide Web was created by Tim Berners-Lee in 1990; Web 2.0 evolved in 1999.
Answer:
def sum_1k(M):
s = 0
for k in range(1, M+1):
s = s + 1.0/k
return s
def test_sum_1k():
expected_value = 1.0+1.0/2+1.0/3
computed_value = sum_1k(3)
if expected_value == computed_value:
print("Test is successful")
else:
print("Test is NOT successful")
test_sum_1k()
Explanation:
It seems the hidden part is a summation (sigma) notation that goes from 1 to M with 1/k.
- Inside the <em>sum_1k(M)</em>, iterate from 1 to M and calculate-return the sum of the expression.
- Inside the <em>test_sum_1k(),</em> calculate the <em>expected_value,</em> refers to the value that is calculated by hand and <em>computed_value,</em> refers to the value that is the result of the <em>sum_1k(3). </em>Then, compare the values and print the appropriate message
- Call the <em>test_sum_1k()</em> to see the result
