12 - Secondary Storage

 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.
External Hard Drive. These are hard drives similar to the type that 
is installed within a desktop computer or laptop computer. ...

Solid State Drive (SSD) ...

Network Attached Storage (NAS) ...

USB Thumb Drive Or Flash Drive. ...

Optical Drive (CD/ DVD) ...


  Variable Storage

  Cloud Storage

  Window Storage

  Software 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?
Hard drive
flash media
"thumb" drive
memory stick
digital camera
removable hard drive
back-up tape
PDA (Palm, Windows Mobile, etc)
Cell phone

  keyboard, mouse, monitor

  I-Pod and Hard drive

  CD-Rom, cellphone, Monitor

  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?

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

  Magnetic - because it has a very large capacity

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

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

 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 ____________.



  non volatile


 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)


  Fuel State

  Solid State


 7. The online company TechHamper is producing a free e-book to distribute to its customers about the latest technology items. Which of the following reasons are valid for why a CD-ROM might be best?
==Advantages of Opitcal Storage=====

#1 Cheap to Produce

#2 Expensive to Produce

#3 Portable

#4 Enough capacity for something like an e-book

#5 Can easily be read by other devices (e.g. computers)

#6 Read-only (cannot write over it)

#7 Massive capacity for storage

#8 No moving parts / reliable and robust





 8. Secondary storage is defined as long-term and non-volatile storage of data and files. What are the characteristics of secondary storage devices that should be considered when selecting a device?
#1 Capacity Size

#2 Smooth feel

#3 Speed

#4 Portability

#5 Response to 'voice interaction'

#6 Durability

#7 Reliability

#8 Cost
