This means that a laptop that comes from the factory with 4GB of memory, likely has two 2GB memory modules installed. To upgrade to 8GB, you can’t just buy 4GB of RAM. You’ll need to remove the existing two 2GB modules and replace them with two 4GB modules, which forces you discard, or try to sell the now-useless 2GB modules.
