      Open-source software

      Open-source software is computer software that is available to the general public in source code form. If a person has enough knowledge about computers and computer programming, he or she can change the program's source code. The source code is like a set of directions that show the program how to operate. People change the codes so that the program will operate in a way that will meet their needs. Sometimes changing the code will make the program run faster. Or it will take problems out of the program. These problems can cause a computer program to shut down. People who change the source code of a computer program share these programs with each other on the Internet. Programmers enjoy being able to improve computer programs on their own. They enjoy being able to ask other people on the Internet for help with their programs. Working together, people can improve computer programs for the good of the group.

      开源软件

      开源软件是一种公开源代码的计算机软件。如果一个人有足够的计算机或者计算机编程知识,他或她就能改变程序的源代码。源代码就是一组指令显示程序如何操作。人们改变编码,使程序以他们想要的方式来运行。有时候改变程序代码会使程序运行更快,或者解决程序中的问题。这些问题可能引起程序关闭。改变计算机程序源代码的人在因特网上与他人共享这些修改过的程序。程序员们乐于自己去改善程序,他们在因特网上寻求关于程序的帮助。在一起工作,人们可以提高计算机程序的集团利益。
