What is HTTP/HTTPS protocols Glossary?
This section delves into the core terms you'll encounter when discussing web communication. Understanding this HTTP/HTTPS protocols Glossary is fundamental for anyone working with internet protocols or web protocols. These terms form the building blocks of how information is exchanged securely and efficiently across the internet.
| Vocabulary | Part of Speech | Simple Definition | Example Sentence(s) |
|---|---|---|---|
| HTTP | Noun | Hypertext Transfer Protocol; the foundation of data communication for the World Wide Web. | Most websites use HTTP to transfer information, but it's not secure on its own. |
| HTTPS | Noun | Hypertext Transfer Protocol Secure; HTTP with a security layer (SSL/TLS). | When you see a padlock icon in your browser, it means the site is using HTTPS for secure communication. |
| Protocol | Noun | A set of rules or procedures for transmitting data between electronic devices. | TCP/IP is a fundamental protocol suite for the internet. |
| Client | Noun | A computer or application that requests services or resources from a server. | Your web browser acts as a client when you visit a website. |
| Server | Noun | A computer or system that provides resources, data, services, or programs to other computers, known as clients. | The website's files are stored on a server that sends them to your browser. |
| Request | Noun / Verb | A message sent by a client to a server, asking for a resource or action. | The browser sent a request to the server for the homepage. |
| Response | Noun / Verb | A message sent by a server back to a client, in reply to a request. | The server's response included the requested web page and a status code. |
| URL | Noun | Uniform Resource Locator; a web address that specifies the location of a resource on the internet. | Please type the URL into the address bar to navigate to the website. |
| SSL/TLS | Noun | Secure Sockets Layer / Transport Layer Security; cryptographic protocols that provide secure communication over a computer network. | SSL/TLS certificates are used to enable HTTPS and ensure data encryption. For more details, you can refer to resources like Mozilla Developer Network (MDN) on TLS. |
| Encryption | Noun | The process of converting information or data into a code, especially to prevent unauthorized access. | Encryption is vital for protecting sensitive data like credit card numbers online. |
| Decryption | Noun | The process of converting encoded or encrypted data back into its original, readable form. | Only the authorized recipient has the key for decryption of the secure message. |
| Port | Noun | A virtual point where network connections start and end. Often used to identify specific services. | HTTP typically uses port 80, while HTTPS uses port 443. |
| GET | Noun / Verb | An HTTP method used to request data from a specified resource. | A GET request is commonly used to retrieve a web page or an image. |
| POST | Noun / Verb | An HTTP method used to send data to a server to create or update a resource. | When you submit a form online, your browser usually sends a POST request. |
| Status Code | Noun | A three-digit number returned by a server indicating the outcome of an HTTP request. | A 200 OKstatus code means the request was successful, while 404 Not Found indicates the resource doesn't exist. |

Common Phrases Used
Beyond individual words, certain phrases are frequently used when discussing HTTP and HTTPS. Learning these expressions will help you understand and participate in conversations about networking basics and cybersecurity terms more effectively. These are common collocations you'll hear in IT settings.
| Phrase | Usage Explanation | Example Sentence(s) |
|---|---|---|
| Make an HTTP request | Refers to the action of a client asking a server for something (e.g., a webpage). | The application needs to make an HTTP request to the API to fetch user data. |
| Receive an HTTP response | Describes the server's reply to a client's request. | After sending the request, the client will receive an HTTP response containing the requested information. |
| Secure the connection with HTTPS | Means to implement HTTPS to encrypt data exchanged between client and server. | It's crucial to secure the connection with HTTPS to protect user login credentials. |
| Check the SSL certificate | Refers to verifying the digital certificate that enables HTTPS. | If you see a browser warning, you should check the SSL certificate to ensure it's valid and trusted. |
| The server returned a 404 error | A common way to say that the requested resource was not found on the server. | I tried to access the page, but the server returned a 404 error. |
| Data is encrypted using TLS | Explains that information is protected by the Transport Layer Security protocol. | You can be confident that your data is encrypted using TLS when you see the HTTPS in the address bar. |
| What's the status code? | A question asked to determine the outcome of an HTTP request, often during troubleshooting. | The page isn't loading; what's the status code the server is sending back? |
