It’s Hard to pin down precisely what “digital resume” means, because people in different job tracks have come up with incredibly varied definitions, some with all different kinds of bells and whistle and some fairly typical. Practically Speaking, the only real requirement for a resume to be “digital” is that you can link it to the internet. That means, for example the details you placed on LinkedIn about your job experience is a digital resume. Likewise, the PDF that you submitted to your website to a directory of resume.

The paper resume has been given an upgrade. Recruiters are looking at the way you present your resume and not just what’s in it. Employers benefit from the advantages offered by online resumes, including access to large number of potential applicants based on specific selection requirements and narrowing their search to applications that have skills and qualities they are looking for. In this Modern era the basic reason why people choose Digital Resume over Traditional CV is because of feasibility and you don’t have to worry about your “document” per se because it is digital and is stored on the net and not physically with you which may have high chances of getting misplaced, destroyed ,etc.  As a result, many companies are increasing the use of this service because they offer significant cost savings over traditional hiring methods. The main advantage of online resumes is that they are instant and quick sending a resume through a mail will take days, and if a company needs to hire someone fast, or are looking for temporary or freelance work, they're unlikely to go to the trouble to post an advertisement, instead they can go the site and shortlist candidates based on the resume.

In many cases, the social media profile and your traditional print resume (CV) are resources meant for different sector of audience .What I think that online profiles are for recruiters and employers who are searching for candidates online. The networks also serve to keep you connected to the people in your professional network, connections that you might be able to harness to help you land a job. The traditional resume is basically meant for the hiring managers at companies where you apply for jobs. Also, More and more people are using social networks to send and receive messages. LinkedIn caters primarily to them, employers are reviewing your profiles to see what kind of person you are outside of work, who you're connected to, and how you present yourself. But since there are 2 sides of coin there are some setbacks too which is that, you might forget to update your LinkedIn, then there may be jobs where the employment dates are still marked “Presently working” even though you no longer work there. LinkedIn will assume you are still working a job unless you tell it otherwise, which is negative impression on the Employer for a Job.
In This Era, what I feel the importance of e-resume is considerable, and one needs to know so that they can accordingly upgrade themselves digitally
