💡 Activity Solution

1️⃣ What is a bit?

• Bit: The smallest unit of information in computing; it can be 0 or 1.

2️⃣ What is a crumb?

• Crumb: A small group of 2 bits.

3️⃣ What is a nibble?

• Nibble: A group of 4 bits (half of a byte).

4️⃣ What is a byte?

• Byte: A collection of 8 bits (2 nibbles or 4 crumbs).

5️⃣ How many bits are in a byte?

• Bits in a byte: 8 bits.

6️⃣ How many crumbs are in a byte?

• Crumbs in a byte: 4 crumbs (8 bits ÷ 2 bits per crumb).

7️⃣ How many nibbles are in a byte?

• Nibbles in a byte: 2 nibbles (8 bits ÷ 4 bits per nibble).

8️⃣ How many crumbs are in a nibble?

• Crumbs in a nibble: 2 crumbs (4 bits ÷ 2 bits per crumb).

9️⃣ What is the lower nibble?

• Lower nibble: The rightmost 4 bits of a byte (least significant half).

🔟 What is the upper nibble?

• Upper nibble: The leftmost 4 bits of a byte (most significant half).

1️⃣1️⃣ What is LSB, why do we call it LSB, and what is its value?

• LSB (Least Significant Bit):
  • It’s the rightmost bit in a binary number.
  • Called “least significant” because it has the smallest weight (2⁰ = 1).
  • Its value contributes the least to the overall binary value.

1️⃣2️⃣ What is MSB, why do we call it MSB, and what is its value?

• MSB (Most Significant Bit):
  • It’s the leftmost bit in a binary number.
  • Called “most significant” because it has the highest weight (2⁷ = 128 in an 8-bit byte).
  • Its value contributes the most to the binary value, often used to indicate sign or priority.
