-RBAC utilizes *roles*, which contain permission rules, and *role bindings*, which grant the permissions defined in a role to a set of users.
+RBAC utilizes four kinds of Kubernetes objects:
+
+Role
+: Defines permission rules in a specific namespace.
+
+ClusterRole
+: Defines permission rules cluster-wide.
+
+RoleBinding
+: Grants the permissions defined in a role to a set of users in a specific namespace.
+
+ClusterRoleBinding
+: Grants the permissions defined in a role to a set of users cluster-wide.
+
+For more information, see [RBAC](/docs/reference/access-authn-authz/rbac/).

-RBAC 使用 *角色* (包含权限规则)和 *角色绑定* (将角色中定义的权限授予一组用户)。
+RBAC 使用四种类别的 Kubernetes 对象：
 
+- **Role**：在特定命名空间中定义权限规则。
 
+- **ClusterRole**：定义集群范围内的权限规则。
+
+- **RoleBinding**：将角色中定义的权限授予特定命名空间中的一组用户。
+
+- **ClusterRoleBinding**：将角色中定义的权限授予集群范围内的一组用户。
