本站所有文章都是我[公众号：小林 coding](https://mp.weixin.qq.com/s/FYH1I8CRsuXDSybSGY_AFA)的原创文章，内容包含图解计算机网络、操作系统、计算机组成、数据库，共 1000 张图 + 50 万字，破除晦涩难懂的计算机基础知识，让天下没有难懂的八股文（口嗨一下，大家不要当真哈哈）！🚀

曾经我也苦恼于那些晦涩难弄的计算机基础知识，但在我啃了一本又一本的书，看了一个又一个的视频后，终于对这些“家伙”有了认识。我想着，这世界上肯定有一些朋友也跟我有一样的苦恼，为此下决心，用图解 + 通熟易懂的讲解来帮助大家理解，利用工作之余，坚持输出图解文章两年之久，这才有了今天的网站！
