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.

  a sequence of binary bits that stores data as bits

  software that enables storage of data

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

  hardware that acts as RAM and temporarily holds information

 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.

 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

  I-Pod and Hard drive

  Digital camera and mouse

  keyboard, mouse, monitor

 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?

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

  Magnetic - because it has a very large capacity

  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.

 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 ____________.

  computational

  non volatile

  powerful

#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)

  Optical

  They are all the same

  Solid state

  Magnetic

 15. Why does a laptop need secondary storage?

  To access the RAM via the monitor

  To store programs that are currently running

  To store data that the processor needs

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

  Magnetic tape

  Flash drive

  CD-RW

  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).

  Optical disk

  Magnetic tape

  Punched card

 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?
storage_cloudstorage1.png

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

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

  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.

 23. What is cloud computing?

  Downloading data to the clouds in the sky

  Storing RAM on an online server

  Storing our data offline instead of online

  Storing our data online instead of on our own hard drive

 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

 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
