📚 Computer Software Types and Interrupt Handling Mechanism | 计算机软件类型与中断处理机制

Computer software forms the foundation of all computing activities, bridging the gap between hardware components and user requirements. This article explores the classification of computer software and explains how the interrupt handling mechanism enables processors to respond effectively to events from both hardware and software. These concepts are essential for CIE Computer Science candidates at both AS and A Level.

计算机软件是所有计算活动的基础，它弥合了硬件组件与用户需求之间的鸿沟。本文探讨计算机软件的分类，并解释中断处理机制如何使处理器能够有效响应来自硬件和软件的各种事件。这些概念对于参加CIE计算机科学AS和A Level考试的考生尤为重要。

1. Classification of Software | 软件的分类

Software can be broadly divided into two categories: system software and application software. System software manages the internal operations of the computer system and provides a platform for application software to run. Application software, on the other hand, enables users to carry out specific tasks such as word processing, data analysis or graphic design.

软件大致可分为两大类：系统软件和应用软件。系统软件管理计算机系统的内部运行，并为应用软件提供运行平台。而应用软件则使用户能够完成特定任务，如文字处理、数据分析或图形设计。

The following table summarises the categories and typical examples:

2. System Software | 系统软件

System software is a collection of programs designed to operate and control the hardware of a computer system. It acts as an interface between the hardware and the application software. The main components of system software are the operating system, utility programs, library programs and translators.

系统软件是用于操作和控制计算机系统硬件的一组程序的总称。它充当硬件与应用软件之间的接口。系统软件的主要组成部分包括操作系统、实用程序、库程序与翻译器。
