relationship software

To better elaborate the relationship between software humanized design and technical content, I personally think that we should start from the purpose of developing software. The software we refer to here should be commercial software for the majority of users, the developme

Relationship between architecture design and software design 1. Architecture Design: Architecture Design is a series of Abstract Software Architecture models that guide large-scale software system design.The software architecture can also break down the system into correspo

This article is excerpted from Revelation: Building users' favorite products.A book and author's blogAnd published in programmer magazine 11Year 05By Marty CaganHe is a product management expert with world reputation. He once served as vice president of Wangjing and eBay.Senior Vice President of product management and design. TranslatedShiyin tribeThe original article is too long. I will repeat it several times. This time I will pick a topic that many developers will be interested in-the

Preface:Anyone who knows about engineering projects in other fields other than the software field, such as chemical engineering and ships, should know that the scale of the project is expanded, and other corresponding labor costs and process computing are involved, the engineering cycle is not linear. More often, you will find that sometimes the scientific theoretical systems applicable to small projects and big projects are different. Judging from

it turns out). The details are divided into the following categories: 1.64-bit (traditional mode/IA32 mode) is not activated. That is, no 64 operating systems are installed for the machine, and only 32-bit operating systems are used. The CPU will only work in pure 32-bit mode, and the hardware and instructions mentioned in the second section are blocked off. (These are the 32-bit mode and the 16-bit program-compliant instructions, which are not detailed here.) ) 1.1. Real mode 1.2. Virtual

1. The relationship between hardware, driver and application software without operating systemIn the absence of an operating system, the device-driven interface is delivered directly to the application software engineer, and the application does not span any levelThe device-driven interface is accessed directly.2. When there is an operating system, the

ProcessFrom planning to the implementation of the strategy, the process is guided by this way of thinking the software development, and the process from the successful experience, can guide the project less detours, thereby improving the quality of software, not only that, the process also on the project cost and schedule control has a great helpTechnologyIncluding the analysis technology, design technology

I learned software engineering some time ago. The software engineering is divided into two major modules. Process-oriented Object-oriented Management Process The next step is UML learning. This is a further supplement to software engineering and a design for some class diagrams and deployment diagrams in the design. Then I learned the design mode

In addition to network devices, character devices and block devices are mapped to file system files and directories through the file system's APIOpen (), close, write (), read (), and other accessible character devices and block devices.A block device is more complex than a character device, where a disk/flash file system, such as Ext3, is first created, and these filesThe system defines the organization of files and directories on the storage media.The application can use the Linux system call

The router system is a combination of hardware and software. The hardware can be an ARM kernel, MIPS kernel, PPC, or Intel CPU. This core part is equivalent to the CPU of the PC we use. A pc generally only needs one Nic, but the router needs multiple NICs. Currently, most PC NICs are connected to the CPU bus through the PCI bus, and all data exchange needs to be processed by the CPU. However, in the design of vro, NICs are generally directly connected

Some time ago, I decided to switch my computer system from the old XP to Windows 7, so some of the daily software installed on Windows 7 was the latest, such as vs2010, sql2008, and office2010, during this period of time, I found a problem that has been ignored by myself: Sometimes it's not enough for old things. Maybe new things can be better done, which can help you greatly improve your work efficiency, but won't try it! The reason for

I encountered a certificate issue today. Symptom: A software used by the Customs Department must be connected to the Internet. However, the problem is that only the administrator can log on to the software. If another user with the administrator privilege is used, the software cannot be used either. the error message "cannot connect to the server" is displaye

Many people engaged in software design love literature, and I am one of them.In fact, you will find thatCodeHow similar the architecture software is to the novels with texts.It is not accidental that the book design patterns begins with an example of Shakespeare's dramatic model.In essence, the design model comes from the dual conception of architecture and novels. Now, I have uploaded a philosophy.Article
