07 - Practice Test

1. Without storage we wouldn't be able to go back to the data/information we have! Storage has changed vastly through the ages. Define a storage device.

hardware that acts as RAM and temporarily holds information

software that enables storage of data

a piece of computer equipment on which information can be stored.

a sequence of binary bits that stores data as bits

2. Developments in the field of storage are progressing every day. There is talk of 'embedded storage chips' becoming common place. Can you name one more type of storage that is not on the below list.

Variable Storage

Cloud Storage

Software Storage

Window Storage

3. A storage device is sometimes defined as devices used to store data in binary format (used for processing later). Which of the following in the list is NOT a storage device?

CD-Rom, cellphone, Monitor

keyboard, mouse, monitor

I-Pod and Hard drive

Digital camera and mouse

4. Three types of storage we commonly look at are 1. Optical 2. Magnetic and 3. Solid State. What would you use for storing images in a digital camera and why?

Solid State - because it is not affected by the camera moving around a lot

None of these options would be suitable for a digital camera.

Optical (DVD/CD) - because it is cheap and portable and can be read by most computers

Magnetic - because it has a very large capacity

5. Most computer systems require secondary storage (this is different from Main Memory and RAM) in order to store files (like the operating system) even when the system is 'off'. This is referred to as ____________.

volatile

non volatile

powerful

computational

6. An E-Book reader would be best off using a particular type of storage for the following reasons. What type of storage is this likely to be referring to?

#1 Fast access

#2 No moving parts / robust (can be moved around a lot with no damage)

#3 Small / sufficiently lightweight

#4 low power (would allow for extended battery life)

Magnetic

Fuel State

Optical

Solid State

7. Serial data access is faster than direct data access.

TRUE

FALSE

8. CD-ROMS can record data over and over again.

TRUE

FALSE

9. What type of storage device would a mobile phone have?

Optical Drive

Flash Memory

Cartridges

HDD

10. Which device would you use to store large amounts of data in your home computer?

Flash memory

Optical disk

Hard Drive

Magnetic tape

11. Which type of optical media has the greatest storage capacity?

DVD-ROM

CD-ROM

They are all the same

Blu-ray Disc

12. What is the name given to copies of data or program files?

Backups

Extras

Stores

Programs

13. Floppy discs can store huge amounts of data.

TRUE

FALSE

14. Which of the following types of storage is the most durable?

Optical

They are all the same

Solid state

Magnetic

15. Why does a laptop need secondary storage?

To store data that the processor needs

To access the RAM via the monitor

To store data, files, and software when the power if turned off (for future use)

To store programs that are currently running

16. Which of the following is an example of Write Once, Read Many (WORM) storage media type?

Magnetic tape

CD-RW

Flash drive

BD-R

17. A type of storage device with no moving parts that uses memory chips instead of magnetic platters is commonly referred to as a Solid-State Drive (SSD).

TRUE

FALSE

18. What would be the most suitable device to transfer a file from home to school?

USB Flash drive

Hard drive

Zip disk

Magnetic tape

19. Fill in the blanks.

_____ (of the following options) has the greatest capacity (greatest amount of storage)

25 GB

1.44 MB

4.7 GB

1 GB

20. Which of the following has the highest data density?

Hard disk

Floppy disk

DVD

21. Which of the following storage devices recording is done by burning tiny pits on a circular disk?

Punched card

Magnetic tape

Floppy Disk

Optical disk

22. Cloud storage is evolving to fight hackers! A decentralized cloud provides more security to any individual or company’s data, as it is not controlled by a single entity. How does this help stop the manipulation/deletion of data?

Cloud storage keeps data in 'high' shelves - out of the reach of hackers.

Data is kept under lockdown. No one, including the user, can access it easily.

Cloud storage is far more cheap than other options, and this helps security

All movements of data are tracked so it is impossible to manipulate or delete data without the user’s permission

23. What is cloud computing?

Storing our data offline instead of online

Storing our data online instead of on our own hard drive

Downloading data to the clouds in the sky

Storing RAM on an online server

24. What are the advantages of cloud computing?

1) You can access your files wherever you are if there is an internet connection and a 
device that you can view and edit them on

2)It will provide you with a faster internet speed 

3)It may save money as there is no cost to maintain the storage i.e. Administration costs

None

25. What are the disadvantages of cloud computing?

1) The occasional downtime - You will not be able to access any of your
applications, server or data from the cloud 

2) You can only control and manage the data and 
applications 

3) Data is vulnerable as cloud storage is a
public service

26. Is the following statement true or false…

An example of a storage device is a hard drive.

True

False

27. What are the advantages of private cloud storage?

1) Efficiency and control as the private cloud storage is hosted either
 on site or a privately hosted environment 

2) High level of customisation (you can choose the infrastructure with specific 
storage and networking characteristics, so the system meets your individual 
needs perfectly) 


3) Has a greater level of security compared to public cloud 
storage as all data is saved and managed on servers in which 
no other company has access to
