前端和后端分別是什么？
從技術(shù)工具來看： 前端：常見的 html5、JavaScript、jQuery... 后端：spring、tomcet、JVM，MySQL...
畢竟，如果這個問題問一個老后端，他掰掰手指可以給你羅列出一堆的名詞來，比如設(shè)計模式、數(shù)據(jù)庫優(yōu)化、框架、JVM、網(wǎng)絡(luò)編程......
從簡單描述來看： 前端：入門簡單，先易后難，做出來的頁面容易有成就感 后端：入門難，深入枯燥還難，整天看代碼很難
前端項目與后端項目是兩個項目，放在兩個不同的服務(wù)器，需要獨立部署，兩個不同的工程，兩個不同的代碼庫，不同的開發(fā)人員。
說到服務(wù)器，那可以了解下這個IP段，會給大家?guī)頍o限的想象
