The first day of web-based understanding

. NET is divided into two main categories

I. Client application c/s

Technology:

Winform

Wpf

MFC MVVM

Second, external side application B/S (Web-side application/web End-/web application)

The current learning technique is the ASP.

Formerly the ASP

Branch: WebForm

Mvc

Then suppose someone asks you would you be ASP.

You have to ask, which direction are you talking about?

WebForm or MVC?

Client run mechanism:

Client services on the user's computer Database on the device

Service side

Client → send request connection → open server database SQL Server connection database ip→ Execute SQL statement → return data → client processing → data viewed by client users

The server is a program running on the servers

Role: For example, send an announcement, each user, have to send a request, connect, and give each user feedback back to the server may be a bit of lag or trouble

The service side is to accept an announcement on the client that feeds the announcement to each user

External terminal operating mechanism:

Three kinds:

First, static page

Enter the URL via the browser → send request → which page to visit → Server →iis→ feedback html+css+js→ browser to show users see

Second, dynamic page with C # code

browser → send request → which page to access → server →iis(see with C # code) →.net Framework (processing C # to framework framework ) →iis (html+css+js+ feedback) → Browser

Iii. dynamic pages with C # code and access to the database

browser → send request → which page to access → server →iis (see with C # code) →.net Framework (processing C # to framework framework)→ Access database → Execute SQL statement →.net Framework →iis (Results of html+css+js+ feedback) → Browser

Operating mechanism:
C
The code executes on the client and accesses the data only to the database on the server.

b/S
The program code executes on the server, the client only renders HTML+CSS, executes the JS code, and all other functions are executed on the server.

The client browser sends the request

IIS on the server (Internet Information Services Manager)
| | (HTML+CSS+JS)
. NET framwork on the server for Code processing

Databases on the server

Why the web is becoming more and more popular
1, do not eat the user's computer Configuration
2, no need to install, anytime and anywhere access to the Web
3, cross-platform (user mobile phone, computer browser can be used in JAVA PHP. NET-made Web pages can be seen)

One, HTML static page suffix name. html. htm

Second, dynamic page with C # code page suffix name. asp. aspx

Third, the dynamic page suffix name with C # code and need to access the database. ASP. aspx

The Java web page suffix name. jsp

PHP does the page suffix name. php

Native Access native IP is 127.0.0.1 or localhost

View public IP

Start Menu →cmd→ipconfig→ipv4 The IP address that is for public viewing
