Cách sử dụng
The word 'external' is used to describe things that come from outside or beyond a particular place or thing. It refers to something that is not connected to or a part of a particular thing or system. For example, if you are talking about a computer, an external hard drive is one that is not built into the computer itself, but is connected to the computer from the outside. Another example, if you are in a meeting and someone from outside of the company comes to speak, they are called an external speaker. In short, external means that it is from outside.
