Imagine your school is planning to store all students' digital projects. You have to choose between a USB flash drive, a CD, and an external hard drive. Which device would you recommend and why, considering storage capacity and ease of use?
CD, because it is the oldest technology.
USB flash drive, because it is small and has moderate storage.
External hard drive, because it has the largest storage and is portable.
None, because all are the same.
Your friend wants to save a video game that is 50 GB in size. He has a DVD (4.7 GB), a USB flash drive (64 GB), and a floppy disk (1.44 MB). Which device should he use and why?
DVD, because it is cheap.
USB flash drive, because it has enough space.
Floppy disk, because it is easy to carry.
None, because none can store the game.
Suppose you are designing a computer for a space mission where weight and size are very important. Which storage device would you choose and what is your reasoning?
Hard disk drive, because it is cheap.
Solid state drive, because it is light and has no moving parts.
CD, because it is flat.
Magnetic tape, because it is old.
You are given a list of storage devices: Blu-ray disc, SD card, and cloud storage. If you need to access your files from anywhere in the world, which would you choose and why?
Blu-ray disc, because it is durable.
SD card, because it is small.
Cloud storage, because it can be accessed from anywhere with internet.
None, because all are the same.
A school wants to back up all its computers every week. They are considering using magnetic tapes or external hard drives. Which would you recommend and why?
Magnetic tapes, because they are fast.
External hard drives, because they are faster and easier to use.
Magnetic tapes, because they are small.
None, because both are outdated.
Imagine you have a choice between storing your photos on your phone’s internal memory or on a cloud service. What factors would you consider to make your decision, and which would you choose?
Internal memory, because it is always available.
Cloud service, because it can be accessed from any device and is safer if the phone is lost.
Internal memory, because it is faster.
Cloud service, because it is free.
You are tasked with explaining to your class how data is stored on a hard disk drive. Which explanation best uses reasoning and evidence?
Data is stored using light.
Data is stored magnetically on spinning disks, and a read/write head changes the magnetism to represent data.
Data is stored in the cloud.
Data is stored using electricity.
A company wants to store huge amounts of data for many years. Should they use SSDs, magnetic tapes, or DVDs? Explain your reasoning.
SSDs, because they are fast.
Magnetic tapes, because they are reliable for long-term storage and can store large amounts.
DVDs, because they are cheap.
SSDs, because they are new.
If you had to compare the storage capacities of a floppy disk, a CD, and a Blu-ray disc, how would you rank them from smallest to largest and why?
CD < Floppy disk < Blu-ray disc, because CDs are smaller than floppy disks.
Floppy disk < CD < Blu-ray disc, because floppy disks have the least and Blu-ray discs have the most storage.
Blu-ray disc < CD < Floppy disk, because Blu-ray discs are older.
Floppy disk < Blu-ray disc < CD, because CDs are the largest.
You are planning to store a large video project. You have a choice between a 32 GB SD card, a 500 GB external hard drive, and a 4.7 GB DVD. Which would you choose and why?
32 GB SD card, because it is small.
500 GB external hard drive, because it has the most space.
4.7 GB DVD, because it is cheap.
32 GB SD card, because it is fast.
Suppose you want to keep your schoolwork safe from being lost if your computer breaks. Which storage method would you use and why?
Only save on your computer.
Use both an external hard drive and cloud storage for backup.
Only use a USB flash drive.
Only use a CD.
Your teacher asks you to explain how data is stored in a solid state drive (SSD). Which explanation shows strategic thinking?
Data is stored using magnets.
Data is stored in microchips using electrical charges, which makes SSDs fast and durable.
Data is stored on spinning disks.
Data is stored in the cloud.
Imagine you are inventing a new storage device for the future. What features would you include to make it better than current devices, and why?
Make it bigger.
Make it faster, more durable, and able to store more data in a smaller space.
Make it heavier.
Make it more colorful.
A friend wants to know why cloud storage is becoming more popular. What is the best explanation using reasoning and evidence?
Because it is new.
Because it allows access from anywhere, is easy to share, and doesn’t require physical devices.
Because it is expensive.
Because it is slow.
You are comparing the future of storage technology. Which trend do you think will be most important and why?
Making devices larger.
Increasing storage capacity while making devices smaller and faster.
Using more CDs.
Making devices heavier.
If you had to store a backup of your computer for 10 years, which device would you choose and why?
Floppy disk, because it is old.
Magnetic tape, because it is reliable for long-term storage.
USB flash drive, because it is small.
CD, because it is shiny.
Suppose you are explaining to your class how data is stored on a CD. Which explanation uses reasoning and evidence?
Data is stored using magnets.
Data is stored using tiny bumps and flat areas that a laser reads as 1s and 0s.
Data is stored in the cloud.
Data is stored using electricity.
You are asked to compare the advantages and disadvantages of using cloud storage versus USB flash drives for school projects. What would you say?
Cloud storage is always better.
Cloud storage can be accessed anywhere but needs internet; USB flash drives are portable but can be lost.
USB flash drives are always better.
Both are the same.
If you could invent a new way to store data in the future, what problem would you try to solve and how?
Make storage devices heavier.
Make storage devices that never lose data, even if dropped or exposed to water.
Make storage devices slower.
Make storage devices more expensive.
A company wants to store important records for 50 years. Which storage method would you recommend and why?
USB flash drive, because it is small.
Magnetic tape, because it is proven to last a long time and is reliable for archiving.
CD, because it is shiny.
Hard disk drive, because it is fast.
