A job board is primarily a website designed to connect job seekers with employers. It serves as a platform where employers can post job openings and job seekers can search for available positions. Users can often filter job listings by various criteria such as location, industry, job type, and experience level. Additionally, many job boards provide resources for resume building, interview tips, and career advice.

In contrast, the other options mentioned—social posting, billboards, and business ads—do not focus specifically on employment opportunities. Social posting might refer to platforms where individuals share personal updates, while billboards and business ads pertain more to general advertising rather than specifically job-related listings.

Final Answer:

A job board is a website for job searching and posting.
