File Operations A) Windows is a multi-root file system with one or more hard disks physically divided into C, D, and E ...... Disk. Each disk is a tree. Linux is a single file system, regardless of the CDE disk. Multiple hard disks, U disks, and CDs are also equivale

Layering is a very important idea in software design, especially for large software systems. Divide and conquer is a commonly used method in computers. For example, the TCP/IP layer-7 protocol stack is a typical hierarchical application. Any qualified software developer must master the hierarchical thinking. Below are several

The assessment of software developers has always been a difficult point in software enterprise management. In my long-term R D management practices and consulting practices, I have summarized some basic principles for assessing software developers, sort out and share with you: 1. Reflect the company's values What typ

advent of Runtime pm and mature as soon as possible, it is particularly important.3. Software Architecture for Generic pmAfter introducing the basic concept of generic PM, let's take a look at its overall implementation in the Linux kernel and abstract the simple software architecture so that the main components of generic PM can be analyzed more carefully in su

. improving the quality of the design of a system also aids in achieving cost-effectiveness. A major obstacle to solving these two problems is the complexity inherent in developing software. this is a result of the complexity of the problems being solved, the wide variety of technologies that may be applied, and the fact that software development is almost purely a design activity. (as opposed to other engi

11, pressure test and load test?Load test: Usually the running time is relatively short, gradually pressurized on the system, until the performance index saturation (such as the corresponding time exceeded the expected requirements, high system resource occupancy, etc.), so as to verify the system expected performance objectives, the corresponding time and so on.Stress testing: long-running, increasing overload (concurrency, loops, multiuser, etc.) until the system generates anomalies and the ab

?The core basic ability of software development is the ability to understand and express things. Why do you say that? From the point of view of communicating with supervisors, customers, product managers, and project managers, you need to be able to understand the context and context in which they speak, to refine their true intentions, to really understand the needs and intentions of others, to be effect

Question I recently started to learn how to become a qualified architect. although I have already attended a series of training courses, I still feel that it is not enough. I found an outline and started to learn it one by one. however, I do not have a solid foundation for software development, so I have to make up for it with diligence. First of all, I would like to refer to others' opinions and write my own understanding of how to become an archit

(1) the specific content of software development is: requirements, Design , Programming And Test ! Requirement: Not only user needs, but all requirements encountered during development. For example, you first need to know what the project is to solve; what data should be input in the test case ...... to clearly understand these requirements, you often need to communicate with customers, project managers, and so on. Design: Before coding, you
