Have you ever heard the word cordless and wondered what it means? It’s a word we see a lot in our daily lives. From phones to vacuum cleaners, many things today are called cordless. But what does this word really mean? Let’s find out.
Basic Meaning of Cordless
The word cordless means something that works without a cord. A cord is a long piece of wire that connects an electronic device to power or to another device. When something is cordless, it does not need that wire to work.
For example, a cordless phone is a phone that does not need a wire to connect to the base. You can carry it around your house easily. The phone uses a battery to work instead of a wire.
