1. what is frountend and backend ?

In software engineering, the terms frontend and backend (or sometimes referred to as back end or back-end) refer to the separation of concerns between the presentation layer (frontend), and the data access layer (backend) of a piece of software, or the physical infrastructure or hardware. In the client–server model, the client is usually considered the frontend and the server is usually considered the backend, even when some presentation work is actually done on the server itself.

In software architecture, there may be many layers between the hardware and end user. The front is an abstraction, simplifying the underlying component by providing a user-friendly interface, while the back usually handles data storage and business logic.

In telecommunication, the front can be considered a device or service, while the back is the infrastructure that supports provision of service.

A rule of thumb is that the client-side (or "frontend") is any component manipulated by the user. The server-side (or "backend") code usually resides on the server, often far removed physically from the user.

2. what is django ?

Django Unchained (/ˈdʒæŋɡoʊ/) is a 2012 American revisionist Western[5] film written and directed by Quentin Tarantino, starring Jamie Foxx, Christoph Waltz, Leonardo DiCaprio, Kerry Washington, and Samuel L. Jackson, with Walton Goggins, Dennis Christopher, James Remar, Michael Parks, and Don Johnson in supporting roles. Set in the Old West and Antebellum South, it is a highly-stylized, heavily-revisionist tribute to Spaghetti Westerns, in particular the 1966 Italian film Django by Sergio Corbucci, whose star Franco Nero has a cameo appearance. The story follows a black slave who trains under a German bounty hunter, with the ultimate goal of reuniting with his long-lost wife.

Development of Django Unchained began in 2007 when Tarantino was writing a book on Corbucci. By April 2011, Tarantino sent his final draft of the script to The Weinstein Company. Casting began in the summer of 2011, with Michael K. Williams and Will Smith being considered for the role of the title character before Foxx was cast. Principal photography took place from November 2011 to March 2012 in California, Wyoming, and Louisiana.

Django Unchained premiered at the Ziegfeld Theatre in New York City on December 11, 2012, and was theatrically released on December 25, 2012, in the United States, grossing over $425 million worldwide against its $100 million budget, becoming Tarantino's highest-grossing movie to date. The film received acclaim from
critics, mainly for Waltz' performance and Tarantino's direction and screenplay, though the film's usage of the word "nigger" and its depiction of violence drew controversy. The film received numerous awards and nominations, winning two out of five nominations at the 85th Academy Awards. Waltz won several awards for his performance, among them Best Supporting Actor at the Academy Awards, Golden Globes and BAFTAs. For his screenplay, Tarantino won an Academy Award, a Golden Globe, and a BAFTA.
