意味 Meaning：The browser is an application for viewing the Web. In simple terms, a browser is "a tool for viewing web pages."
The functions of a browser can be summarized in three areas: search, download, and rendering.
解説 Commentary：The browser has three functions: search, download, and rendering.
The first is searching for a web server by URL. The user types the URL into the browser. URL is the address on the web. Each web server has an assigned URL. The browser looks at the URL to find the right server. This process is called search.
The second is bringing the information to the user's computer. The browser takes the information from the server one after another. This process is called download. The information can be in the file form of HTML, PDF, JPG, MP3, etc.
The third is processing information so that humans can easily understand it. In many cases, downloaded information is packaged for easy transmission to the computer but is too hard for ordinary humans to read and understand.
Therefore, browsers process the information into a more tangible form, making it easier for humans to understand. This process is called rendering.
