In Web test, the difference and connection between B/S and C/S architecture

1. In Web test,The difference and connection between B/S and C/S architecture: The biggest advantage of B/S is that it can be operated anywhere without installing any specialized software. As long as there is a computer that can access the Internet, it can be used, and the client has zero maintenance. The expansion of the system is very easy.

2. Different structure: B/S structure is a network structure model that emerged with the development of the Internet and the emergence of the web. This model unifies the client and allows the core business processing to be completed on the server side. C/S structure is a kind of software system architecture, which is also very common in life.

3. C/S and B/S hardware environments are different. C/S is usually built on a dedicated network, a small network environment. B/S is built on the wide area network, with a strong range of adaptation, and usually has an operating system and a browser.

4. The differences between C/S structure and B/S structure are: different hardware environment, different client software, and different user interface. Different hardware environments C/S structure: C/S structure is based on the local area network, and connection and data exchange services are provided between local area networks through special servers.

5. The difference between b/s architecture and c/s architecture: the hardware environment is different: C/S is generally built on a dedicated network, and connection and data exchange services are provided through a dedicated server between the network environment and the local area network in a small area.

Web front-end multi-end programming development framework structure?

The rapid popularity of Angular 1 is that people from other interactive application development environments will find that they have similar model-view patterns for developing single-page web applications.

There are mainly c/s architecture and b/s architecture, which are mainly composed of applications and remote servers that generally need to be installed on the client. Its advantage is that the traffic volume between the two sides of the communication is small, because most of the information is stored locally. The disadvantage is that the maintenance and upgrade of the client is more troublesome, which is generally suitable for large-scale systems.

Back-end development is to write the background, various business logic, data processing, module interface, client interface, etc. Back-end developers are usually proficient in a Web programming language and a database management system.

Characteristics: Good application structure, 2. Two-way data binding, 3. Description, HTML template, 5. Embedding, injection and testing. Advantages: The template has powerful and rich functions, and comes with extremely rich angular instructions.

What are the commonly used architectures for developing dynamic websites?

1. Bootstrap: One of the mainstream frameworks, Bootstrap is based on HTML, CSS and JavaScript. It is simple and flexible, making Web development faster.Html5-boilerplate: This framework can quickly build a robust and adaptable webapp or website.

2. ASP is ActiveServerPages, which is a combination of hypertext identification language (HTML), script and CGI (public gateway interface) developed by Microsoft. It does not provide its own specialized The programming language allows users to use many existing scripting languages to write ASP applications.

3. Common web page layout structure left and right frame layout - left and right frame layout structure is a layout structure often used by some large forums and enterprises. Its layout structure is mainly divided into pages on the left and right sides.

4. Web applications are roughly divided into two types, namely dynamic websites and static websites. Static websites are static pages written in HTML. Dynamic websites are dynamically generated and sent to the client according to different requests of users. They are usually written in HTML language and dynamic scripting language (ASP, PHP, JSP) and other languages.
