Answer:
C. 2^16
Explanation:
In Computer Networking, there are five (5) classes of IP addresses, these include;
- Class A
- Class B
- Class C
- Class D
- Class E
The various classes of IP address are represented by the value of their first octet. The first octet value of Class B is 128-191 with a subnet mask of 16.
Hence, from the IP address 149.130.x.y where x and y are 8-bit numbers. The x and y equals 16-bit numbers.
Thus, 2^16 devices can connect to the Wellesley network before we run out of IP addresses.
Here is a Python program:
tmp = input().split(' ')
c = tmp[0]; s = tmp[1]
ans=0
for i in range(len(s)):
if s[i] == c: ans+=1
# the ans variable stores the number of occurrences
print(ans)
