Understanding Internet Speed and Data Units

The video tutorial explains the concept of bits per second (BPS) as a measure of network speed, detailing how bits and bytes relate to kilobytes and megabytes. It discusses the differences in unit definitions between modems and storage devices, and demonstrates how to calculate download times for files. The tutorial concludes with a practical exercise for students to test and record network speeds using online tools.

What does 'bps' stand for in network communications?

• Binary per second

• Bits per second

• Bandwidth per second

• Bytes per second

How many bytes are there in a kilobyte?

• 2048

• 1024

• 1000

• 100

What is the power of two that defines a megabyte?

• 2^20

• 2^10

• 2^30

• 2^40

What was the speed of the first modem mentioned in the video?

• 56 kbps

• 28.8 kbps

• 14.4 kbps

• 128 kbps

In modem terminology, what does 'k' in kbps stand for?

• 1000

• 100

• 10

• 1024

Why is it important to convert all units to the same type when calculating download times?

• To make the numbers smaller

• To ensure accuracy in calculations

• To simplify the process

• To avoid using a calculator

How do you convert bits per second to bytes per second?

• Multiply by 8

• Divide by 8

• Add 8

• Subtract 8

What is the approximate download time for a 1 MB file at 3600 bytes per second?

• 1 minute

• 10 minutes

• 4 minutes and 51 seconds

• 2 minutes

What should students record when testing internet speeds?

• Only ping

• Only upload speed

• Only download speed

• Ping, download speed, and upload speed

What is the purpose of setting up a Google spreadsheet for the speed test?

• To calculate average speed

• To aggregate data from different tests

• To compare with other schools

• To share results with friends
