For someone that is not well averse with web development the terms front-end and back-end development seem like jargon. But it is pretty easy; they are different entities that work together to ensure smooth running of a site. Most of the time front-end development is taken as web designing; that is wrong because web design is the outlook and layout of the site. That is the colors, font size, look and feel within the site. While front-end development deals with the functionality, that is, the freelance web designer Singapore that turns web designs into a live interactive website.
Back-end development is the backside of a site where one is focused mainly on how the site works. A back-end developer makes updates and changes and monitors how the site works; he/she ensures responsiveness and speed is top notch. A code has to be written for the database information to be transferred to the browser. There are languages such as python, java, ruby on rails and PHP that are used to create dynamic sites which are able to store database information; therefore data is frequently updating and changing.
