A byte is approximately the amount of storage space it takes to store one single character (keystroke). This includes upper and lowercase letters, numerals, spaces, tabs, punctuation, line breaks, hyphens, parenthesis, underscores, mathematical symbols, etc., pretty much anything you can type.

Example: Washington would require 10 bytes because there are 10 letters.

Example: I love U 2! would require 11 bytes because there are 6 letters, 1 numeral, 3 spaces, and 1 punctuation.

A kilobyte (KB) is a unit often used to measure the size of smaller computer files.
1 KB = 1024 bytes (2¹⁰ bytes)

A megabyte (MB) is a unit often used to measure the size of larger computer files and removeable disks.
1 MB = 1024 KB's (2²⁰ bytes)

A gigabyte (GB) is a unit often used to measure the size of hard drives.
1 GB = 1024 MB's (2³⁰ bytes)

A terabyte (TB) is a unit often used to measure the size of massive hard drives.
1 TB = 1024 GB's (2⁴⁰ bytes)

1 TB = 2¹⁰ GB's = 2²⁰ MB's = 2³⁰ KB's = 2⁴⁰ bytes = (approx. 1 trillion bytes)
