Study Notes
Communication Medium
- Clients and servers are primarily applications (software) rather than hardware and can reside on the same computer.
- Communication mediums can include local networks, the internet, or any designated communication channel.
HTTP - Request and Response
- A URL example:
https://www.ccdisorsogon.edu.phserves as the address to access a web resource. - The default port for HTTP traffic is 80 but is often omitted in URLs.
- The protocol "https" ensures secure communication between the client and server.
Domain Structure
- Domains consist of multiple levels:
- “www” is the third-level domain or host.
- “ccdisorsogon” is the second-level domain.
- “edu.ph” is the top-level domain.
- An example URL:
https://ccdisorsogon.edu.ph/index.htmlis converted to an IP address (e.g., 168.28.176.243) by DNS or local cache.
HTTP Transaction Process
- Step 1: Entering a URL initiates the process in a browser.
- Step 2: The browser resolves the domain to an IP address.
- Step 3: An HTTP request is sent to the server to access resources (e.g., web pages).
- Step 4: The server processes the request and retrieves the requested file.
- Step 5: The server sends back a response to the browser, which then renders the content for the user.
Types of Web Content
-
Simple/Static Content:
- Consists mainly of HTML documents.
- Relies on client-side technologies like HTML and CSS.
- Characteristics include simplicity, small size, and fast loading times.
-
Dynamic Content:
- Involves more advanced processing with greater interactivity.
- Utilizes technologies such as JavaScript on the client side and server-side technologies like PHP and Java.
- Content can include a mix of HTML, scripts, programming code, and executable programs, allowing for functionality and versatility.
