What HTTP method should I use for a login (authentication) request? -
Answer If your login request is via a user supplying a username and
password then a POST is preferable, as details will be sent in the HTTP
messages body rather than the URL. Although it will still be sent in plain text,
so always make sure to encrypt passwords.
Three-Tier Architecture - Answer A client-server configuration that is
organized into three layers:
1. Presentation Layer
- Concerned with delivering information to the user and UI related issues
2. Business Logic Layer
- Concerned with data & data validation, dynamic content processing, and
generating content that is delivered to the client-side
3. Data Access Layer
- Backs up Business Logic Layer and concerned with how we store and
interact with the data, typically, in the form of a database and access this
data through an API
Front-End Web Development - Answer The front-end is where we are
delivering the content to the user or client, typically through a browser where
the user sees and interacts with the content. The front-end is also known as
client-side. The front-end is usually produced with HTML, CSS, and JavaScript
[frameworks].
Back-End Web Development - Answer The back-end is refers to the server
side of an application and everything that communicates between the
database and the browser, or client. The back-end consists of a server, app,
and database. This server-side application directly interacts with the
database via an application programming interface (API), which pulls, saves,
or changes data.
