Question

question: 1
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?
options: 4, 8, 16, 32

Explanation:

Step1: Recall bit addressing formula

Each bit can be 0 or 1, so for \( n \) bits, the number of unique addresses is \( 2^n \).

Step2: Apply formula for \( n = 4 \)

Substitute \( n = 4 \) into \( 2^n \), we get \( 2^4 = 16 \).

Answer:

C. 16 (assuming the options are labeled as A. 4, B. 8, C. 16, D. 32)
