Units of Storage 1.5 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 5 th 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
