ELI5: Explain Like I'm 5

Internal field separator

Okay, so imagine you have a bunch of words on a piece of paper, like "cat dog bird" and you want to separate them from each other. You could use a comma, right? So it would be "cat, dog, bird." That comma is acting as a separator between the words.

Now, when we talk about an internal field separator, we're basically talking about a separator that's already built into your computer or device. This separator is used to separate different parts of text from each other.

So, let's say you were working on a spreadsheet with lots of data in it. You might have something like this:

Name | Age | Gender
---|---|---
Sally | 28 | Female
Tom | 35 | Male
Liam | 19 | Male

See how each bit of data is separated by a vertical line? That's called a pipe symbol ( | ) and it's an example of an internal field separator.

The computer knows that each piece of data is separated by that pipe symbol, so it can easily organize and manipulate the information.

Internal field separators can be different symbols, depending on what program you're using. Sometimes it's a comma, sometimes it's a semicolon, and sometimes it's something else entirely. But the important thing is that it helps the computer understand how the data is laid out.
