计算机科学（Computer Science，缩写CS）是系统性研究信息与计算的理论基础以及它们在计算机系统中如何实现与应用的实用技术的学科。它通常被形容为对那些创造、描述以及转换信息的算法处理的系统研究。
计算机科学包含很多分支领域：有些强调特定结果的计算，比如计算机图形学；而有些是探讨计算问题的性质，比如计算复杂性理论；还有一些领域专注于怎样实现计算，比如编程语言理论是研究描述计算的方法，而程序设计是应用特定的编程语言解决特定的计算问题，人机交互则是专注于怎样使计算机和计算变得有用、好用，以及随时随地为人所用。

与计算机工程的区别
一、概念区别
计算机工程（Computer Engineering）就是研究计算机如何运作并且做到更快捷更精准。其主要包括两方面：计算机软件与硬件工程。计算机工程学学生通过学习数学、物理、计算机科学相关课程，分析设计和研发计算机软件与硬件（计算机芯片、电路板、调制调节器和打印机）。
计算机科学（Computer Science，有时缩写为CS）是系统性研究信息与计算的理论基础以及它们在计算机系统中如何实现与应用的实用技术的学科。
二、研究领域
计算机科学研究领域比计算机工程更为广泛。包括：计算机制图、数据处理、数据库建设、信息技术、网站设计建设与管理、游戏设计、计算机编程
三、计算机科学属于理科，倾向于理论性；计算机工程学属于工科，更趋向于应用。
