Understanding Bytes, Bits, and Proportionality

The video tutorial covers practice problems related to proportional relationships. It begins with converting yards to miles, explaining the constant of proportionality. The tutorial then analyzes various equations to determine if they represent proportional relationships. It further explores proportional relationships using tables and equations, emphasizing the constant of proportionality. Finally, the video discusses data transmission on the internet, explaining the relationship between packets, bytes, and bits.

• 5280 yards

• 5280 yards

Which of the following equations represents a proportional relationship?

• y = 3x + 5

• y = 0.08x

• y = x^2 + 2

• y = 120 - x

If y = 5/2x, what is the value of y when x = 4?

• 8

• 6

• 12

• 10

What is the constant of proportionality in the equation y = 5/2x?

• 2

• 5/2

• 1/2

• 2/5

How many bytes are there in 2 packets if each packet contains 1500 bytes?

• 3000 bytes

• 6000 bytes

• 4500 bytes

If you have 30,000 bytes, how many packets do you have?

• 15 packets

• 20 packets

• 25 packets

• 30 packets

What is the relationship between bytes and bits?

• 1 byte = 2 bits

• 1 byte = 4 bits

• 1 byte = 16 bits

Which equation can be used to find the number of bits in a given number of packets?

• Bits = 1,000 * Packets

• Bits = 8 * Packets

• Bits = 1,500 * Packets

• Bits = 12,000 * Packets
