**URL (Uniform Resource Locator):**
A URL is the address of a specific webpage or resource on the internet. It is a string of characters that provides a way to locate and access a particular website or web page. The URL consists of several components, including the protocol, domain name, path, and sometimes additional parameters.

**Address Bar:**
The address bar is the input field or text box in a web browser where users can type or paste the URL of a website they want to visit. It is located at the top of the browser window, typically below the browser's toolbar. The purpose of the address bar is to allow users to enter the desired website address and navigate to that specific webpage.

**Explanation:**
When we want to visit a specific website, we need to enter its address in the address bar of the browser window. The address is known as the URL (Uniform Resource Locator), which uniquely identifies the location of the webpage or resource on the internet.

The address bar provides a convenient way for users to input the URL of the website they want to visit. It allows users to type or paste the URL directly into the address bar and then press Enter or click the "Go" button to navigate to the desired webpage.

The URL entered in the address bar is then used by the browser to establish a connection with the web server hosting the website. The browser sends a request to the server, asking for the specific webpage or resource associated with the URL. The server responds by sending back the requested content, which is then rendered by the browser and displayed to the user.

In summary, the address of a website is known as the URL, and it is entered in the address bar of the browser window to navigate to the desired webpage. The address bar is an essential component of web browsers and allows users to easily access websites by typing or pasting the URL.
