Resume
A short, targeted summary of your work history and skills, usually one page and at most two. You adjust it for each job. Standard in the US and Canada and for most private-sector jobs worldwide.
CV (curriculum vitae)
In the UK, Pakistan, India, the Gulf and much of Europe, "CV" simply means the same short document as a resume, sometimes with a photo and personal details. In academia and medicine everywhere, a CV is a longer, complete record: education, research, publications, conferences, teaching and awards, often many pages.
Biodata
Common in South Asia for government jobs and some private ones: a resume plus personal details such as date of birth, nationality, marital status and father's name. Add those lines to any template in the CV maker.
Which one to send
Follow the job advert. If it says CV and you apply in Pakistan, the UK or the Gulf, send a one or two-page document like a resume. If you apply for an academic or research post, send the full academic CV.
