General Features of Operating Systems

An operating system is a master control program which controls the functions of the computer system as a whole and the running of application programs. All computers do not use the same operating systems. It is therefore important to asses the operating system used on a particular model before initial commitment because some software is only designed to run under the control of specific operating systems. Some operating systems are adopted as «industry standards» and these are the ones which should be evaluated because they normally have a good software base. The reason for this is that software houses are willing to expand resources on the development of application packages for machines functioning under the control of an operating system which is widely used. The cost of software is likely to be lower in such circumstances as the development costs are spread over a greater number of users, both actual and potential.

Mainframe computers usually process several application programs concurrently, switching from one to the other, for the purpose of increasing processing productivity. This is known as multiprogramming (multi-tasking in the context of microcomputers), which requires a powerful operating system incorporating work scheduling facilities to control the switching between programs. This entails reading in data for one program while the processor is performing computations on another and printing out results on yet another.

In multi-user environments an operating system is required to control terminal operations on a shared access basis as only one user can access the system at any moment of time. The operating system allocates control to each terminal in turn. Such also require a system for record locking and unlocking, to prevent one user attempting to read a record whilst another user is updating it, for instance. The first user is allocated control to write to a record (or file in some instances), other users being denied access until the record is updated and unlocked.

Answer 2

操作系统的一般特征
操作系统是控制计算机系统作为一个整体和应用程序的运行的功能的主控制程序。所有的计算机不使用相同的操作系统。因此，重要的是要对用户实现最初的承诺之前，完成一个特定的模型中使用的操作系统，因为有些软件的设计仅仅能够在特定操作系统的控制下运行。有些操作系统采用«行业标准»，这些都应该被进行评估，因为它们们通常有良好的软件基础。原因是因为：软件公司都愿意扩大对应用程序包的开发资源，计算机操作系统被在广泛使用的控制下工作。可能在实际的或潜在的情况下较低的开发成本被分布到更大数量的用户。大型计算机通常用从一个切换到另一个处理多个应用程序的方式，来达到提高处理效率的目的。这就是所谓的多道程序（多任务的微型计算机的情况下），这需要一个强大的操作系统结合工作调度设施来控制程序之间的切换。同时要求读出一个程序数据而处理器执行计算的另一个和打印出的结果上另一种。在多用户环境中的操作系统下，则需要控制在一个共享接入终端的基础操作，因为只有一个用户可以在任何时刻访问系统。操作系统分配的控制依次在每个终端。这样还需要一个系统的记录锁定和解锁，以防止一个用户试图读取，而另一个用户的记录被更新了，比如。第一个用户分配的控制写入一条记录（或在某些情况下的文件），其他用户被拒绝访问，直到记录被更新和解锁

我也是计算机专业，要看不少英文材料。可以很肯定的说，没有这类软件
人能识别一个词在不同情况下是上面意思，而软件无法做到这一点
人脑识别单词意思都可能出错了，更何况让软件智能识别

最方便的就是金山词霸的截词功能了，省去搜索时间，自己分辨该是哪个意思

Answer 4

我是英语专业不是计算机，但是我可以告诉你这篇文章用网页翻译出来跟专业翻译意思差不多，可以忽略误差

先回答了才能看见问题。百度知道很奇葩。
