What are Metadata?

Metadata are data about data

for example lets say we have a hello.txt file which have 1 line of text “Hello World”

In this case “Hello World” are data

Metadata if this data would be:

• file size
• file format
• file created at
• filename
• file location
• created by

Other good example that i heard once:

Telephone connection

Data is the conversation itself, meaning the phone call content

Metadata:

• when was the connection
• how long was the connection
• between which numbers
• in which country or between which countries
