Units of Storage1.5 Types of Memory and Storage
In this lesson, you will learn:• What storage is• Learn what a byte is• Learn the common units of storage
Your iPhone has 16GB of Storage?• What does that
mean?!?!• You know that 16GB
isn’t as big as 32GB.• And 16GB is bigger
than 8GB but what does all this mean?• Let’s go back to the
beginning!
Let’s take a BYTE out of it all! • A BYTE is not a bite• A BYTE is one piece
of information• A tiny piece of
information• Let’s see…
What is a Byte?• A byte is 1 piece of
information• 1 letter in a document
is normally about 1 byte• Mr. Jennings will
demonstrate on NOTEPAD. • Notepad is a simple
widget on most computers
1 letter = 1 byte (about)• 2 letters = 2 bytes (about)• The word “byte” = 4 bytes• So a byte is 1 piece of information
What is a KB??• Think back to 5th
Grade Math• What is a km or a kg?• Km = kilometer• Kg = kilogram
• K = kilo• Kilo = 1000• Kb = 1,000 bytes• Make sense?
So what’s a MB?• MB = Megabyte• Let’s make a prediction• If KB = 1,000 bytes…• What do you think:• MB equals?
What does a megabyte equal?• If KB = 1,000 bytes• Then MB = 1,000,000 bytes (approx)• Mega = 1 million• Let’s make another prediction.
Back to the Original Question…• What does GB stand for?• GB = Gigabyte• So…• KB = 1,000 (thousand)• MB = 1,000,000 (million)• GB = 1,000,000,000 (billion)
New Kid on the Block• TB = Terabyte• Make a prediction• How much is a TB?
How much is a terabyte?• TB = 1,000,000,000,000 bytes or a 1,000 GB• Generally not available to public• That’s a lot of storage!
In this lesson, you learned:• What storage is• Learn what a byte is• Learn the common units of storage
