It serves as our gateway to the online world. Let's dive in and demystify these concepts in an easy-to-understand language.Ī browser is a tool that allows us to access various resources, documents, websites, and web applications over the internet. Web development involves understanding the intricacies of networks, browsers, and the client-server model. IP addresses can be represented in two versions, IPv4 (e.g., 192.168.0.1) and IPv6 (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334), with the latter providing a larger address space due to the growth of the Internet. Just as each house on a street has a specific address to ensure the mail gets delivered to the right place, each device on a network has an IP address to ensure data reaches the intended recipient. It serves as the device's unique address, allowing data to be sent and received accurately.įor example, think of an IP address like a house address. This is where IP(Internet Protocol) addresses come into play. When two systems or devices want to connect on a network, they need a way to identify and send data to each other. Just as a network brings devices together, the Internet brings networks together, enabling seamless communication and access to information on a global scale. It can be thought of as a vast network of networks. The Internet is a global system that connects devices and networks all around the world. It connects computers and networks worldwide, allowing information and data to flow between different locations globally. The most well-known example of a WAN is the Internet itself. WAN (Wide Area Network): A Wide Area Network is designed to connect devices over a large geographical area, often spanning multiple cities or even countries. A common example of a MAN is a cable television network, which delivers internet services to different households in a city. It interconnects multiple LANs within a specific region. MAN (Metropolitan Area Network): A Metropolitan Area Network extends the reach of a LAN and covers a larger geographical area, such as a city or a town. This enables sharing files, printing documents, and accessing shared resources within the network. For example, a LAN can connect computers, printers, and other devices within a home network. It allows devices in close proximity to communicate with each other. LAN (Local Area Network): A Local Area Network refers to a network that covers a small geographic area, typically within a home, office, or building. Let's explore some common types of networks and gain a better understanding of how they work. Networks can exist on various scales, and they can be either wired or wireless, depending on the context. This article originally appeared in HotWired.In the world of web development, networks play a crucial role in connecting devices and enabling communication. There are also mail servers, name servers, FTP servers, news servers, proxy servers, and chat servers. They can serve other types of information as well - like images and video and sound files. As you know by now, HTTP servers serve hypertext information, or Web pages. In this article, I have primarily been talking about HTTP servers. And like fast-food joints, different servers serve different things. There are almost as many different types of servers as there are fast-food chains. And we all know that no one likes to wait around for burgers or for Web pages. Caching can speed up the process of downloading pages. It's kind of like stockpiling information. When information is cached in your machine and you want to view a Web page or an image a second time, the client can grab the information and present it to you more quickly than if it was reaching onto a server on the Internet. Sometimes the client will store the information on your computer in order to save time. You see the result of this transaction in your browser. At this point, the browser/client grabs the information from the server and puts it in your computer.
