  (回答：算法分析是通过检查算法的时间和空间需求来评估算法的效率和复杂性的过程。这有助于确定特定任务的最佳算法，并使开发人员能够优化他们的代码。)

• 2.35. A server is a computer or system that provides resources, services, and data to other computers, known as clients, over a network. Servers can host websites, manage databases, store files, and run applications.
  (回答：服务器是一台计算机或系统，通过网络向其他计算机（称为客户端）提供资源、服务和数据。服务器可以托管网站、管理数据库、存储文件和运行应用程序。)

• 2.36. The main difference between a compiler and an interpreter is how they process high-level programming languages. A compiler translates the entire program into machine code before execution, while an interpreter translates and executes the program line by line during runtime.
  (回答：编译器和解释器之间的主要区别在于它们如何处理高级编程语言。编译器在执行前将整个程序翻译成机器代码，而解释器在运行时逐行翻译和执行程序。)
