计算机科学：
计算机科学可以被称为对计算机以及计算概念的研究。它基本上是研究与程序形式的数据交互的过程。它通过使用各种算法来处理信息。因此，计算机科学涉及对硬件和软件以及网络和互联网等其他组件的研究。计算机科学的硬件部分研究计算机的基本设计及其工作过程。计算机科学的软件部分涉及编程概念和语言的研究。计算机科学还涉及操作系统和编译器。
数据科学：
数据科学基本上是一个通过使用各种科学方法、算法和过程从数据中提取信息和知识的领域。因此，它可以被定义为各种数学工具、算法、统计和机器学习技术的组合，从而用于从数据中找到有助于决策过程的隐藏模式和见解。数据科学处理结构化和非结构化数据。它与数据挖掘和大数据都有关。数据科学涉及研究历史趋势，从而利用其结论重新定义当前趋势并预测未来趋势。
