API & network topics

Today i learned about fetch API in javascript and other network protocols. what is API? Application Programming Interface(API) are a type of software interface that enables applications to exchange data,features, and functionality. Types of APIs Public APIs: Open APIs that are available to any business or developer. Partner APIs: Only available to authorized businesses and developers. Private APIs: Only accessible by one private enterprise. Composite APIs: An aggregate of multiple APIs. (E.g.E-commerce checkout: Purchasing an item on Amazon involves multiple steps (adding to cart, checkout, payment) that are handled by a composite API in a single transaction.) URI VS URL uniform resource identifiers (URIs) and uniform resource locators (URLs) aren't the same. A URI can be a name, a location, or both, while a URL specifies just the location of a resource. FETCH (fetch is a concept or function) Fetch API is a specific JavaScript interface used to make HTTP requests to access data from APIs or other network resources. The fetching process, REST API REST stands for Representational State Transfer and API stands for Application Program Interface. REST is a software architectural style that defines the set of rules to be used for creating web services. It allows requesting systems to access and manipulate web resources by using a uniform and predefined set of rules. http headers HTTP headers contain metadata in key-value pairs that are sent along with HTTP requests and responses. They can be used to define caching behavior, facilitate authentication, and manage session state. https status code HTTP status codes are three-digit codes that indicate the outcome of an API request. They are included in the API's response to the API client.

what is API?

     Application Programming Interface(API)  are a type of 
  software interface that enables applications to exchange 
  data,features, and functionality.

Types of APIs

Public APIs: Open APIs that are available to any business or developer.
Partner APIs: Only available to authorized businesses and developers.
Private APIs: Only accessible by one private enterprise.
Composite APIs: An aggregate of multiple APIs. (E.g.E-commerce checkout: Purchasing an item on Amazon involves multiple steps (adding to cart, checkout, payment) that are handled by a composite API in a single transaction.)

URI VS URL
uniform resource identifiers (URIs) and uniform resource
locators (URLs) aren't the same. A URI can be a name, a
location, or both, while a URL specifies just the location of
a resource.

FETCH (fetch is a concept or function) Fetch API is a specific JavaScript interface used to make HTTP requests to access data from APIs or other network resources.

The fetching process,

REST API

REST stands for Representational State Transfer and API stands for Application Program Interface. REST is a software architectural style that defines the set of rules to be used for creating web services.
It allows requesting systems to access and manipulate web
resources by using a uniform and predefined set of rules.

http headers
HTTP headers contain metadata in key-value pairs that are sent along with HTTP requests and responses. They can be used to define caching behavior, facilitate authentication, and manage session state.
https status code
HTTP status codes are three-digit codes that indicate the
outcome of an API request. They are included in the API's
response to the API client.
