What are the difference between "Resume", "CV" & "Biodata" ?

This is a long lasting confusion. and I am sure even after reading this article, doubts will remain ;) but i have tried to clear the confusion as much as possible. Hope we leave this page with a "Finally i know" :)

RESUME

Resume is a French word meaning "summary". A resume is ideally a summary of one's education, skills and employment when applying for a new job. A resume does not list out all details of a profile, but only some specific skills customized to the target job profile. It thus, is usually1 or at the max2 pages long. A resume is usually written in the third person to give it an objective and formal tone.

Structure: A good resume would start with a Brief Profile of the candidate, Summary of Qualifications, followed by Industry Expertise and then Professional Experience in reverse chronological order. Focus is on the most recent experiences (with responsibilities and accomplishments), and previous experiences are only presented as a summary. This would be followed by Education details and/or Professional Affiliations and/or Voluntary Initiatives.

C.V. - CURRICULUM VITAE

Curriculum Vitae is a Latin word meaning "course of life". It is more detailed than a resume, generally2 to3 pages, or even longer as per the requirement. A C.V. lists out every skill, all the jobs and positions held, degrees, professional affiliations the applicant has acquired, and in chronological order. A C.V. is used to highlight the general talent of the candidate rather than specific skills for a specific position.

BIO-DATA

Bio Data is the short form for Biographical Data and is an archaic terminology for Resume or C.V. In a bio data, the focus is on personal particulars like date of birth, gender, religion, race, nationality, residence, marital status, and the like. A chronological listing of education and experience comes after that.

Resume is a French word which means "SUMMARY"

CV - Curriculum Vitae is a Latin word which means "COURSE OF LIFE"

CV have more detailed than a resume, generally02 to03 pages, or even longer as per the requirement. It indicates candidate’s professional experience. 

Bio Data is the short form for "BIOGRAPHICAL"

In a Bio Data the focus is on personal particulars like date of birth, gender, religion, marital status nationality & residence etc. . .

I think that resume and CV are the same thing. Biodata is a part of both, It is used to articulate the candidate's personal specifications.

They are used interchangeably and refer to the same aspect i.e. one's personal as well as professional profile.  While Resume is French, CV is Latin and Biodata is (as seen) English terminologies used for the profile of a person
