  1. User Interface: This is the portion which is visible to the users such as forward/backward, refresh buttons, the address bar and all the other things that can be seen on a screen when the browser is opened.
  2. Browser Engine: The rendering engine and the browser’s UI are connected by a bridge i.e. browser engine. It produces the output as per the input, by operating the rendering engine.
  3. Rendering Engine: This engine is responsible for producing the requested content by a user to the browser and then displaying it on the screen. It renders the HTML into a readable form on the screen. WebKit is one of the open-source rendering engines used by some of the mainstream browsers such as Google Chrome, Opera and Safari. 
  4. JavaScript Interpreter: All websites and webpages are based on JavaScript. These pages are all written in JavaScript. As a result, the interpreter converts the pages, which are then sent to the rendering engine to display the final render.
  5. Networking: Security and communications on the internet are controlled by the networking part. It allows to lower or control the network traffic and is also used for HTTP requests and to cache the documents that are retrieved.
  6. UI Backend: It is used to create simple widgets like windows and boxes. The standard interface exposed by this backend is cross-platform. 
  7. Data Storage: This layer is based on continuity in the storage area. Cookies and other types of data may need to be saved locally by the browser regularly. Additionally, browsers support storage mechanisms such as localStorage, IndexedDB, WebSQL, and FileSystem.

Overall, our lives would be way slower and uneasy if there is no means of accessing the web.
