What is the difference in meaning between and or do they have same meaning?

"And" and "or" are completely different in meaning. They are conjunctions, which means they connect words, phrases, or clauses.

Here's the breakdown:

And:

* Indicates that both things are true. For example, "I like apples and oranges." This means you like both apples and oranges.

* Adds to the previous information. It's often used to build on a statement.

Or:

* Indicates that at least one of the things is true. For example, "You can have apple or orange." This means you can choose either apple or orange, but not necessarily both.

* Offers an alternative. It suggests a choice between two or more options.

Here are some examples:

* And: "I went to the store and bought some milk."

* Or: "Do you want coffee or tea?"

In summary: "And" means both things are true, while "or" means at least one thing is true.
