Learning objectives

Learning Objectives

  • All students will be able to identify the different measure units used for storage devices.

  • Most students will be able to state each storage measure units in terms of files.

  • Some students will be able to explain the importance of knowing the measure units.


Storage measurement units

Storage measurement units

  • What is bigger 10 or 100?

  • What is bigger 10TB or 100EB?

  • Is it just enough that you know that 1 EB = 1000 PB?


Storage measurement units1

Storage Measurement Units

  • The basic measure unit used to measure stored data in a computer is a byte.

  • Bytes are also the smallest unit used and they represent one single character in a text file.

  • Any text document that has more than 1000 characters or more than 200 words aprox. will become a 1 KiloByte file.


Storage measurement units2

Storage Measurement Units

  • 1 Kilobyte (KB) is 1000 bytes

  • What do we measure in KB?


Storage measurement units3

Storage Measurement Units

  • 1 Megabyte (MB) is 1000 Kilobytes

  • What do we normally measure in MBs?


Storage measurement units4

Storage Measurement Units

  • 1 Gigabyte (GB) is 1000 Megabytes

  • What do we normally measure in GBs?


Storage measurement units5

Storage Measurement Units

  • 1 Terabyte (TB) is 1000 Gigabytes

  • What device(s) has a storage capacity of at least 1 TB?


Storage measurement units6

Storage Measurement Units

  • 1 Petabyte (PB) is 1000 Terabytes

  • 1PB = 13 Years of HD-TV Videos

  • 20 PB = The amount of data processed by Google in one day.


Storage measurement units7

Storage Measurement Units

  • 1 Exabyte (EB) is 1000 Petabytes

  • 500 Exabytes = All contents from the Internet (www)


Storage measurement units8

Storage Measurement Units

  • 1 Zettabyte(ZB) is 1000 Exabytes

  • 1 Yottabyte(YB) is 1000 Zettabytes


Rainbow group work

Rainbow Group Work

  • Each group will be given a table. Each row has a description of an specific measure unit. Write in the space provide the measure unit that fits with the description. (3 minutes)

  • Failure to complete the task in the given time will mean extra homework.

  • Red: Fernando A, Mariana L, Karina, Emilio

  • Green: Fernanda, Alexa, Mateo, Jimena

  • Blue: Aldo, Fernando G, Mariana C, Jessica

  • Yellow: MaJo, Frida, Arturo, Rafael


Rainbows

Rainbows

  • Inside the new teams, all members will discuss their results generated in the previous step and will try to reach a unified conclusion. (2 minutes)

  • Failure to complete the task in the given time will mean extra homework.

  • Rainbow 1: Fernando A, Alexa, Fernando G, Frida

  • Rainbow 2: Fernanda, Mariana L, Mariana C, Arturo

  • Rainbow 3: Aldo, Karina, Mateo, Rafael

  • Rainbow 4: MaJo, Emilio, Jimena, Jessica

Now is your turn to show what you know

Now is your turn to show what you know.

  • Individually you will answer a small quiz.

  • The main purpose of this activity is so you can know where you need to improve. (5 minutes)

  • MB

  • PB

  • KB


Quiz markscheme explain

Quiz Markscheme Explain

  • 1 marks: A limited response that indicates very little understanding of the topic.

  • 2-3 marks: A reasonable description of how the measurement units are used. Reasons are missing or not enough detailed.

  • 4 A clear detailed explanation (with reasons) of why the measurement units are important.


Reasons

Reasons

  • Can be fooled by someone telling you the computer has 1000 MB of RAM and sound a big number.

  • Can make a bad purchase if you think 100 GB is enough to download all your movies.

  • Can have trouble with CC or emails when trying to send an attached file.

  • Couldn’t differentiate between 10MB or 10 GB.


Medal and goal example

Medal and Goal example.

  • Give mark from 1 to 4 according to the markscheme
