1. 程序：
程序，顾名思义，就是程序员用编程语言开发的一组简单的指令，可以准确地自动化、收集、管理、计算、分析数据和信息的处理。
2. 数据：
顾名思义，数据是由计算机处理并存储在文件或文件夹中的信息，转换为便于移动或处理的形式，可以是文本文档、图像、音频剪辑等形式。
程序和数据的区别：
| Program | Data |
|---|---|
| Programs are collection of software instructions understandable by CPU. | Data are information stored in computer hard disc. |
| Programs goes to CPU, then according to these instructions CPU take decision regarding which pins on CPU are turned on or off. | Data does not go into CPU as instructions, instead used by programs to execute certain processes. |
| It is used to provide expected output whenever executed by computer. | It is used to help organization in effectively determining cause of problems that occurred. |
| Programs helps in decision making purpose. | Data does not help in any decision making purpose. |
| Types of programs include word processors, game programs, graphic programs, data base systems, etc. | Types of data includes personal data, transactional data, web data, sensor data, etc. |
| Programs are important for computer as it make computer active and therefore computer without program are considered dump box. | Data are important for computer and how will they perform as computer process depends upon type of data. |
| Programs are not simple and hard to understand. | Data are simple and easy to understand. |
| Programs are used to speed up input and output processes in machine. | Data are used to establish baseline and help one to visualize relationship among what is happening in different locations, departments and systems. |
| Different languages of program can be C, C++, Java, Pascal, Python, etc. | Different forms of data can be images, text documents, audio clips, software programs, Boolean data, etc. |
