Being proficient in the fundamentals of web design will help you to stand out from the crowd and get a job with ease. Developers should know about the User Interface (UI) elements and structural elements of the website. For e.g.: Domain Name System (DNS), Cloud Storage, etc. 


HTTP or HyperText Transmit Protocol empowers the server to communicate easily with the user. REST or Representational State Transfer is a link between systems that uses HTTP to collect data and conduct various operations on it. REST can be thought of as the intermediary between the front and back end.
