学士学位论文___《操作系统》算法多媒体演示.doc

摘要 操作系统（Operating System，简称OS）是一种管理电脑硬件与软件资源的程序，同时也是计算机系统的内核与基石，更是计算机硬件和其他软件及计算机用户之间的联系纽带。操作系统是最重要的计算机系统软件，同时也是最活跃的学科之一，其发展极为迅速。操作系统的算法是学生学习《操作系统》这门课程最为重要的一个环节，操作系统的经典算法包括进程调度算法、存储器连续分配方式中分区分配算法、页面置换算法、磁盘调度等。 FLASH软件进行可视化演示，观看者可以通过动画的方式对操作系统和算法有更好的认识和理解。操作系统算法演示正是利用FLASH来制作演示各种算法，使者可以很好的理解，起到事半功倍的效果。 计算机操作系统；经典算法FLASH动画 Abstract Operating system (Operating System, referred to as OS) is a kind of management computer hardware and software resources of the process, but also computer system kernel and the cornerstone, is the link between computer hardware and software and other computer users. Operating system is the software of computer system is the most important, but also one of the most active subject, its development is very rapid. The operating system is a course in computer science students must to learn ,and the algorithm is learning the course operating system a most important link of the classical algorithm, including the operating system process scheduling algorithm, memory allocation partition algorithm, page replacement algorithm of disk scheduling mode, etc.. Operating system algorithm to understand and relatively complex, so the use of FLASH software for visual presentation, visitors can have a better awareness and understanding of the operating system and algorithms by the way of animation.The operating system algorithm for multimedia presentation is to make the presentation of various algorithms using FLASH, so that scholars can be well understood, play a multiplier effect.
