计算机基础教育在大学教学内容和教学目标上已发生重大变革，特别是针对文、理科的学生，缺乏工科学生的思维训练，该课程不仅让学生全面了解计算机和计算机应用技能，还要培养学生的计算思维能力，即培养学生用计算机解决问题的方法解决其他专业领域中的问题的能力和将计算机应用拓展到其他专业领域，并因此产生用计算机的新技术解决现实生活中尚未解决的问题的能力。本书主要内容包括计算机基础与计算思维、Windows 7 操作系统、程序设计与软件开发基础、Office 2013 办公软件的使用、计算机网络与信息安全、多媒体技术和数据库技术基础等内容。本书适合作为各类高等院校非计算机专业计算机基础课程的教材。

本书是一本系统地介绍计算机工作原理、培养学生计算机应用技能和计算思维能力的大学计算机基础课程的教材。

计算机基础教育是大学新生入学以后所接触到的第一门计算机学科知识教育，是大学基础课程之一，对于引导学生深入了解计算机常识、熟悉计算机应用、培养计算思维、助力专业技能教育以及衔接后续信息技术课程等均具有非常重要的意义。为进一步推动高等学校计算机基础教育的发展，教育部高等学校大学计算机课程教学指导委员会发布了《大学计算机基础课程教学基本要求》（简称《基本要求》）。《基本要求》提出了“宽专融”的课程体系，它也将“大学计算机”这门通识型课程设置为必修课程。本书是一本系统地介绍计算机工作原理、培养学生计算机应用技能和计算思维能力的大学计算机基础课程的教材。本书共分7 章，第1 章介绍了计算机基础相关知识和计算思维的概念；第2 章介绍了Windows 7 操作系统；第3 章介绍了程序设计与软件开发基础，包括程序设计、算法与数据结构基本概念以及C 程序基本内容；第4 章介绍了Office 2013 办公软件的使用；第5 章介绍了网络与信息安全相关的内容；第6 章介绍了多媒体技术基础和Photoshop 软件基本应用；第7 章简要介绍数据库技术的基本原理。本书由陆军主编。参与编写的人员还有安德智、武光利、丁要军、李燕、师晶晶、任文、张琛、李振江、岳海云。本书的编写力求做到由浅入深、层次分明、概念清晰，案例涉及的知识点全面且实用。由于编者水平有限，加之时间仓促，书中难免存在不足和疏漏之处，敬请广大读者批评指正。编 者2019 年于兰州
