A公司是一家生产空调的企业，其在国内空调行业名列前茅，在某些地区市场上还处于领先地位。A公司始终牢记"质量第一"的企业生存之道，对产品的生产采取了极为苛刻的质量标准，从源头上严把质量关。该公司每年花费大量的资金用于生产一线员工的培训，不断提高一线员工的质量意识和技能。并且对生产的每批空调都进行抽检，以确保产品能够符合相应的质量标准和使用性能。与此同时，对销售的产品提供完善的售后服务（三包服务），得到消费者的一致认可。要求：（1）从质量管理的角度简述质量成本的类型，并判断该公司为了保证质量付出的成本有哪些。（2）大多数的现代质量管理方法试图在生产过程中保证质量而不是在生产完成或提供服务之后检查货物和服务。全面质量管理（TQM）是一项很受欢迎的质量鉴证技术。试简述TQM的要点。

WLANs are increasingly popular because they enable cost-effective connections among people, applications and data that were not possible, or not cost-effective, in the past.
