• Uniform Interface: Resources are only accessible as representations and the rules for processing that representation are described through self-descriptive messages.
• Stateless: Every client request to the server is self-contained and subsequent requests do not require information from prior requests.
• Client-Server: A client and server must be present in the architecture.
• Cacheable & Layered System: Caching and other techniques are utilized in order to increase network efficiency.

Hypertext Transfer Protocol (HTTP) is a protocol that provides a standardized way for computers to communicate with each other. It has been the foundation for data communication over the internet since 1990 and is integral to understanding how client-server communication functions.

Features:

• Connectionless: When a request is sent, the client opens the connection; once a response is received, the client closes the connection. The client and server only maintain a connection during the response and request. Future responses are made on a new connection.
• Stateless: There is no dependency between successive requests.
• Not Sessionless: Utilizing headers and cookies, sessions can be created to allow each HTTP request to share the same context.
• Media Independent: Any type of data can be sent over HTTP as long as both the client and server know how to handle the data format. In our case, we'll use JSON.

Elements:

• Universal Resource Identifiers (URIs): An example URI is http://www.example.com/tasks/term=homework. It has certain components:
• Scheme: specifies the protocol used to access the resource, HTTP or HTTPS. In our example http.
• Host: specifies the host that holds the resources. In our example www.example.com.
• Path: specifies the specific resource being requested. In our example, /tasks.
• Query: an optional component, the query string provides information the resource can use for some purpose such as a search parameter. In our example, /term=homework.
