Question

consider this sequence of bits: 1011111111010001111111101 how many bytes long is that sequence of bits? choose 1 answer: 24 12 3 4

Explanation:

Step1: Count the number of bits

The bit sequence is "1011111111010001111111101". Let's count the bits: Let's go through each character. The length of the bit string: Let's count: 1,0,1,1,1,1,1,1,1,1,0,1,0,0,0,1,1,1,1,1,1,1,0,1. Wait, wait, maybe I miscounted. Wait, let's do it properly. Let's write the sequence: "1011111111010001111111101". Let's count the digits:

1 (1), 0 (2), 1 (3), 1 (4), 1 (5), 1 (6), 1 (7), 1 (8), 1 (9), 1 (10), 0 (11), 1 (12), 0 (13), 0 (14), 0 (15), 1 (16), 1 (17), 1 (18), 1 (19), 1 (20), 1 (21), 1 (22), 0 (23), 1 (24). Wait, that's 24 bits? Wait no, wait the original sequence: Let me check again. Wait the user's image: "1011111111010001111111101" – let's count the characters:

1,0,1,1,1,1,1,1,1,1,0,1,0,0,0,1,1,1,1,1,1,1,0,1. Wait, that's 24 characters? Wait no, wait 1 (1), 0 (2), 1 (3), 1 (4), 1 (5), 1 (6), 1 (7), 1 (8), 1 (9), 1 (10), 0 (11), 1 (12), 0 (13), 0 (14), 0 (15), 1 (16), 1 (17), 1 (18), 1 (19), 1 (20), 1 (21), 1 (22), 0 (23), 1 (24). So 24 bits. But 1 byte is 8 bits. So to find the number of bytes, we divide the number of bits by 8.

Step2: Calculate bytes

Number of bits = 24. Number of bytes = 24 / 8 = 3? Wait, no, wait maybe I miscounted the bits. Wait let's re-express the sequence: "1011111111010001111111101" – let's count the length:

Let's write it as a string: "1011111111010001111111101"

Let's count the characters:

1 (1), 0 (2), 1 (3), 1 (4), 1 (5), 1 (6), 1 (7), 1 (8), 1 (9), 1 (10), 0 (11), 1 (12), 0 (13), 0 (14), 0 (15), 1 (16), 1 (17), 1 (18), 1 (19), 1 (20), 1 (21), 1 (22), 0 (23), 1 (24). So 24 bits. Then 24 bits / 8 bits per byte = 3 bytes? Wait but the options include 3. Wait but maybe I made a mistake. Wait let's check again. Wait the sequence: "1011111111010001111111101" – let's count the digits:

Wait 1,0,1,1,1,1,1,1,1,1 (10), 0,1,0,0,0 (15), 1,1,1,1,1,1,1,0,1 (24). Yes, 24 bits. So 24 / 8 = 3. So the answer is 3? Wait but the options: 24, 12, 3, 4. Wait 24 bits is 3 bytes (since 1 byte = 8 bits). So 24 / 8 = 3. So the correct answer is 3. Wait but let's confirm: 8 bits = 1 byte. So 24 bits: 24 ÷ 8 = 3. So the number of bytes is 3.

Answer:

3
