A Byte is the fundamental unit of digital information and corresponds to a set of 8 bits.

If a bit (0 or 1) is like a letter in a digital alphabet, a byte is like the first word that can be formed with those letters. Grouping bits into sets of 8 allows for the representation of more complex information.

For example, a single byte can represent:

• A number from 0 to 255.

• A single text character (such as the letter "A" or the symbol "%").

The byte is the standard unit for measuring file size and device storage capacity. We use its multiples to quantify data:

• Kilobyte (KB): 1,024 bytes

• Megabyte (MB): 1,024 KB

• Gigabyte (GB): 1,024 MB

• Terabyte (TB): 1,024 GB
