Chapter 1 The History and Future of Computers
1.1 The Invention of the Computer
It is hard to say exactly when the modern computer was invented. Starting in the 1930s and through the 1940s, a number of machines were developed that were like computers. But most of these machines did not have all the characteristics that we associate with computers today. These characteristics are that the machine is electronic, that it has a stored program, and that it is general purpose.

计算机专业英语及翻译Unit 7
Unit 7 The Fundamentals of ComputerSoftwareText 1 Data StructureA data structure is a data type. Its values are composed of component elements that are related by some structure.Since a data structure is a data type, it has a set of operations on its values. In addition, there may be operations that act on its component elements. The operations of a structured data type might not only act on the values of the data type, they might also act on component elements of the data structure.The data type’s arrays and record s are native to many programming languages. By using the pointer data type and dynamic memory allocation, many programming languages also provide the facilities for constructing linked structures. The first two higher-level abstract data types are stacks and queues. They are extremely important to computing.A stack is a data type. Its major attributes are the way the insertion and deletion of its elements. The only element that can be deleted or removed is the one that was inserted most recently. Such a structure is said to have a last-in/first-out (LIFO) behavior.Queues are familiar to us. The line of people waiting for service at a bank is an example of queues. The main feature of queues is that they follow a first-come/first-served rule. In queues, the earliest element inserted is the first served. In social settings, the rule appeals to our sense of equality and fairness.There are many applications of the first-in/first-out (FIFO) protocol of queues in computing. For example, the line of I/O requests waiting for access to a disk drive might be a queue. The line of computing jobs waiting to be run on a computer system might also be a queue.参考译文数据结构数据结构是一种数据类型，其值是由通过某种结构相互关联的组成元素所构成的。

What is a computer
• Your friend is performing the "name-calling function". Your friend takes as input the visual presence of a human being in the room and gives as output a spoken name (e.g. "Sue"). You, in turn, are performing what we might call the "change - name - to - number - and - push + function". You take as input what your friend gave as output: a name. For each name that you take as input, you give as output a "1" preceded by the "+" sign. So you take as input, "Sue," and give as output, "+,1".
• What all functions have in common is that they take something as input and give something as output. To know that something is a function in this sense, we don't need to know anything about how it arrives at its output. All that matters is that there is a regularity in the way it determines the output. This is the broadest, most general concept of a function. In the long run, we are going to consider a variety of quite different types of functions. For the moment, however, we are going to focus our attention on tቤተ መጻሕፍቲ ባይዱe most familiar type of function -- those that always give exactly the same output for the same input. It is this type of function that lies at the heart of digital computers, the most familiar type of computer. (Later we will explore the fascinating case of "probabilistic" computers, which implement a broader type of function which does not always give the same output for the same input. Some people refuse to call these machines, "computers" and to call the rules that they implement, "functions". But more on these later.)
