Clients include devices that connect to servers and request data, software or services. Clients can be desktops or laptops. They can also be mobile phones or tablet computers. Servers can be classified as specialized computer systems which store and process data. This includes files, databases, programs, etc. These servers are used for mail servers, file servers, and web servers.
Client-server communication consists of a set of rules that servers and clients agree to follow while communicating with each other. These rules can be referred to as network protocols.
A protocol specifies the format and structure for messages that are sent by one computer to another via a network like the internet. These rules apply for email, videoconferencing, and Voice over Internet Protocol (VoIP), as well as other types of communication.
Web servers, mail servers, and file servers use client-server communication to distribute information over the internet. These servers provide users with information by offering services such as email, websites, and video conferences.
HTTP Push or Pull is the preferred style of server communication. The latter style is most commonly used for real-time software such as stock markets and chat apps. It automatically sends out updates to the client without their explicit request.
The first method of communication is the least resource intensive, but it's better for static content. You send a request and wait until you get a response. This is often done by an in-the-background daemon.
HTTP is the most common form of client-server communication, but other methods are available. HTTP Push, Pull, Long-Polling, and others are among the options.
Web client development
The server receives the request for a webpage on the website. This page may contain HTML files or other files. The server decides what data it will include in its response depending on the contents of that page, for example, text, styling, buttons to allow user interaction, images, or other assets.
The response is then sent to the browser, allowing the user to see it. The user may also be able to visit other pages by clicking on the links.
Client-server communication comes in many forms, all with their advantages and disadvantages. HTTP Push/Pull, Long and Quick Polling, etc., are all examples.
HTTP uses a thread or process that listens to each request. This first request is handled according to the protocol, and is followed by a new request. This pattern is repeated until a request/response cycle ends.
This is the most efficient and effective way for a web server to deal with a large amount of requests. This style of programming is not recommended for applications like real-time, where the users want to see all updates as soon they are made.
Before you create your own web app, it's crucial to know the differences between communication styles. Your choice of style will affect how interactive your application is and how much bandwidth you use.
