Question: 1

Question

Suppose we used an Internet Addressing protocol that used 4 bits to encode a single address. How many devices would be supported on the Internet? How many unique addresses would there be?

4

8

16

32

Answer 1

If we use 4 bits to encode a single address, we can calculate the number of unique addresses that can be created using the formula \(2^n\), where \(n\) is the number of bits.

In this case, \(n = 4\):

\[ 2^4 = 16 \]

So, with 4 bits, you can support 16 unique addresses.

Thus, the answer is 16.
