12、Software engineering is the application of a systematic, disciplined, quantifiable approach to the development, operation, and maintenance of software.it encompasses techniques and procedures, often regulated by a software process, with the purpose of improving the reliability and maintainability of software systems.The effort is necessarily by the potential complexity of those systems, which may contain millions of lines of code.
The term software engineering was popularized by F.L.Bauer during the NATO Software Engineering Conference in 1968.The discipline of software engineering includes knowledge.tools, and method in software requirements, software design, software construction, software testing, and software maintenance tasks.Software engineering is related to the disciplines of computer science, computer engineering, management, mathematics, project management, quality management, software ergonomics, and systems engineering.

11、A motherboard is the central or primary printed circuit board ( ) making up a complex electronic system, such as a modern computer.it is also known as a mainboard, baseboard, system board, and so on.On Apple computers, a logic board, and is sometimes abbreviated casually as mobo. Most motherboards produced today are designed for so-called IBM-compatible computers, which held over 96% of the global personal computer market in 2005.Motherboards for IBM-compatible computers are specifically covered in the PC motherboard article. A motherboard, like a backplane, provides the electrical connections by which the other components of the system communicate, but unlike a backplane also contains the central processing unit and other subsystems such as real time clock, and some peripheral interfaces.A typical desktop computer is built with the microprocessor, main memory, and other essential components on the motherboard.Other components such as external storage, controllers for video display and sound, and peripheral devices are typically attached to the motherboard via edge connectors and cables, although in modern computers it is increasingly common to integrate these “peripherals” into the motherboard.(5)、What is the main point of this text?
