  6. Server And Client

    Server: Provides resources, services, or data in response to client requests over a network.

    Client: Requests resources or services from servers and renders them for users in web browsers.

  7. Web Page

    A web page is a single document or file displayed in a web browser. It typically contains a combination of text, images, multimedia elements, hyperlinks, and styling information (provided by CSS) that is presented in a visually cohesive manner.

    Web pages are written using markup languages such as HTML (Hypertext Markup Language), which define the structure and content of the page. Other technologies like CSS (Cascading Style Sheets) and JavaScript can be used to enhance the appearance and interactivity of web pages.

    Examples of web pages include articles on news websites, product pages on e-commerce sites, blog posts, and about pages on personal websites.

  8. Website

    A website is a collection of related web pages that are interconnected and hosted on a web server. Websites are accessible over the internet and are typically organized into a hierarchical structure, with a homepage serving as the entry point to the site.

    Websites serve various purposes, including providing information, offering products or services, facilitating communication, and hosting online communities. They can be static, containing fixed content that rarely changes, or dynamic, with content that is frequently updated or generated dynamically based on user interactions.

    Websites can range in size from simple personal blogs to complex e-commerce platforms, social networks, and enterprise web applications.

  9. URL

    A URL is a standardized address used to identify and locate resources on the internet. It specifies the protocol used to access the resource (such as HTTP or HTTPS), the domain name or IP address of the server hosting the resource, and the path to the specific resource on the server. A url typically consists of several components:

    Protocol: specifies the communication protocol used to access the resource, such as HTTP (hypertext transfer protocol) or HTTPS (HTTP secure).

    Domain name: identifies the specific server or host where the resource is located. Domain names are human-readable labels that correspond to numeric IP addresses.

    Path: specifies the location of the resource on the server’s file system or within the website’s directory structure. It can include directories, filenames, and query parameters.

    Query parameters: optional parameters that are appended to the url to pass additional information to the server, such as search queries or form data.

    Example of a url: https://www.expertscomputeracademy.com/learn/html/ Protocol: HTTPS Domain name: www.expertscomputeracademy.com.Com and Path: learn/html/
