The answer to whether CV (Curriculum Vitae), Resume and Digital Portfolio are the same thing is easy. No, they are not at all the same thing. 

 A CV (Curriculum Vitae) is a written overview of a person's experience and other qualifications for a job opportunity. It gives a comprehensive description of everything you have done. You need to update the CV everytime you accomplish or gain something academically or professionally. Whereas, resume is a written complilation of education, work experience, credentials and accomplishments. Most professional positions require applicants to submit a resume and cover letter and a part of the application letter. On the other hand, a Digital Portfolio is a compilation of materials which emplifies your skills, beliefs, qualifications, education, training and experiences. It also provides confidence to your personality and work. 

Unlike CV, you should always try to keep a resume short and precise. The resume may contain information about the recent works and projects along with basic personal information of the candidate. Thus, it would provide the recruiter an overall idea about the candidate for the job. Like a resume, the portfolio should be updated and relevant with time. A digital portfolio may consist of images, vectors and other pictures that make it much more appropriate to the viewers and help them to evaluate properly. Online portfolios have become very common today. It allows the portfolio to share easily through mails and other websites. 

Nowadays, many job seekers are using skilled portfolios and career portfolios that also includes resumes instead of cover letters. Thus, a resume is used for job search, a CV is used for academic purposes and a digital portfolio is used to illustrate the quality and enhanced skills.
