Recalling the first two chapters: the terms "computer information" and "From traditional computers to ubiquitous computing" is about your computer configuration, hardware, and other works about the first two chapters, designed to help us understand computer Operating mechanism inside, so some of the problems solved phenomenon observed by the usual phenomena with theoretical knowledge but can not explain.
To Chapter 3: This chapter has finally come to the field and we live very close to the - software. As a software engineering (actually turn professional) sophomore, tell the truth, their understanding of the software is not thorough. However, the software has a great interest, not only because it is closely related to our lives, and each software behind the hidden mysteries always people can not help wonder its magic.
Not surprisingly, at the beginning of this chapter we will sentence the example of Tencent QQ, which is closely associated with living longer with us, but the software, the program gives the software = + data + document from the teacher saying this example. The classification software is varied: there are classified by function, there are classified by size, but also by the type of work classification, we can see the software as much as the number of large. Recognizing the software is a huge family, but also learn the software as each individual has the features to the software from the whole to have a partial understanding. The software needed to run the operating system as a basis for a "middleman." Thereby defining the basic concepts of the operating system, software that is used to control and manage the computer system resources. Operating systems including hard disk operating system, UNIX operating system, Linux operating system, Mac OS and Windows operating systems, windos operating system for the majority of users familiar with, so after their lessons, I realized that each operating system has its own unique features and characteristics where Mac OS is the operating system on the Apple Macintosh line of computers, simple and reliable, I think this is one of Apple's products so popular reasons for it. Of course in addition to computers, smart phones also have a different operating system to Android and IOS most famous.
After the teacher talked about development software, we introduce the software crisis, which means higher and higher demands on software developers, and software engineering discipline is defined. Software development process consists of the following eight steps:
1. Problem Definition 2. Feasibility study 3. Requirements Analysis 4. Overall design 5. Detailed design 6. 7. program development software testing 8. maintenance software every step is very important, due to differences in software project and task to be completed not a set of tasks applies to all software projects.
The application software will have to take into account the user interface and user experience, which is a measure of the availability of important standard software, which requires software developers to comply with the three principles of design, can design a different user interfaces for different users, thereby enhancing user experience design user satisfaction.
When I saw Iphone user interface design appreciation sector in class, I realize that I like to use has been the cause of the Iphone will be on its user interface design, indeed, Iphone phone easy to use and full-featured, safe, not only that, some of Apple's mobile phone store-specific software is indeed very powerful (think the only downside is charging too ..)
About the evolution of programming languages has gone through machine language , assembly language and high-level language three stages of development, and now numerous programming languages, so I think the teacher said, very reasonable: To select a language proficiency in it, mastering it will enough.
Finally, I learned the job classification software industry, according to different needs, divided into many forms, each of which also contains a number of professional, I am pleased that, through this section of the study provides a general direction for my future employment let me know the different requirements of different professional career in the software industry, making it possible to develop their own hobbies according to their ability, all in all, this lesson for me to learn in the future planning and development plays an important role.
