###・ガード(guard)
「認証」と呼ばれることが多く、ログイン機構の種類を表す。
例えば、ECサイトの「会員」と「管理者」など。
ログイン画面の数だけguardがあるイメージのようです。
###・ガードドライバー（driver）
ログインの認証状態をどうやって管理するか。
多くの場合は、セッション認証（session)
###・プロバイダ(provider)
誰（モデル）をどんなロジック（プロバイダドライバ）でログインさせるかの認証方法。
###・モデル（model）
誰をログインさせるか。
多くの場合、ログインユーザーを管理しているテーブルに対応するモデルクラス。
###プロバイダドライバ(driver)
ログイン認証の中核となるロジック。パスワードをどのように検証し、どのような条件ならログインを許可するかなど。
以上です！
