Often there are small partners of some computer technology and concepts are not very clear, produce a lot of misunderstandings, and even Zhang Guan Li Dai, in the chat together and it is difficult to explain clearly to each other, after thinking hard, finally came up with some analogies that can be very well articulated "Hardware, operating systems, cross-platform, application software, development languages, code"The relationship between.
1. Hardware
- Land (Intel) vs. Sea (AMD): Hardware is like a vast natural environment, in which Intel and AMD are like two different territories (land and sea), each with unique resources and characteristics. These hardware platforms provide the basis for the upper layers of software to run.
2. Operating system
- amusement park: The operating system, on the other hand, is a virtual world built on top of the hardware, providing an environment for the software to run in.
- Castle (Windows) and Ship (Linux): Different operating systems are like different styles of buildings in a playground. Windows, with its rich functionality and user-friendly interface, is like a magnificent castle, while Linux, with its openness and flexibility, is more like a ship sailing freely on the sea.
3. Application software
- Amusement Program: Applications are like carousels, pirate ships, roller coasters, and other rides in an amusement park that provide users with rich functionality and an entertaining experience. Each application is developed based on a specific operating system, just as the rides need to be built in a certain area of the amusement park.
4. Development language
- plant: Development languages are like factories that produce play equipment; they provide the tools and methods to create application software.
- Parts Factory (intermediate languages C, C++) and Device Factory (high level languages Java, Python, C#, etc.): Intermediate languages (e.g., C, C++) are more like parts factories in that they provide the basic building blocks for constructing software but may be less efficient when writing large-scale software directly, while high-level languages (e.g., Java, Python, C#) are more like equipment factories in that they are able to more efficiently produce complete software products that support a wide range of functionality and complex logic.
5. Code
- Production technology: Code is the production technology in these factories, and different development languages have different rules and syntaxes for writing code that determine how ideas are transformed into runnable software.
6、Cross-platform
- a porter: Cross-platform technology is like a porter in a playground, it is able to move applications (like roller coasters) running on one operating system (e.g., Castle Windows) to another (e.g., Ship Linux) and keep them running properly. This technology enables software to be used across different hardware and operating system platforms to provide a consistent user experience.
Through the above analogy, we can more intuitively understand the relationship between these technical concepts and their role in software development, there is a poorly expressed plea for partners to make valuable suggestions!
