Ui Design + WordPress: Curso Completo de Criação de Sites

Continuous integration is the practice of every developer merging their work into a shared mainline at least once a day, with an automated build and test run on each merge, so that integration problems surface within minutes of being created rather than weeks later at release time.

Unit testing is the practice of writing small automated checks that call one piece of code in isolation, a function, a class or a module, with known inputs and assert on its outputs, so that a change which breaks that behaviour fails a test within seconds of being made.

Full-stack development is the ability to build both halves of a web application: the front end that runs in the browser (HTML, CSS and JavaScript) and the back end that runs on a server (a language, a framework and a database), plus the API that joins them.

A CDN is a worldwide network of servers that answers requests for your site from a location near the person asking, instead of sending every request back to the single machine your site runs on.

DNS is the distributed lookup system that turns a hostname such as getting-digital.net into the IP address a browser can connect to, by walking a chain of nameservers whose answers are then cached for a lifetime the domain's owner publishes.

SSL/TLS is the protocol that encrypts the connection between a browser and a server and, by way of a certificate signed by a certificate authority, proves the server is entitled to answer for the domain in the address bar.
