Not much difference as they carry similar meaning and used differently. "I work as a sales manager" or "my job is to carry out sales function". Realise that job refers to the scope of work."I work at" using refers to the company (eg I work at IBM), "I work in" usually refers to the place or location (eg, I work in singapore). Businessman encompass doing business, trader only involve in "buying and selling or some products" only. A trader may not be a businessman as he may be trading on behalf of someone else. A businessman covers all aspect of a company which he owns.

Bill's answer is correct. However some people say 'it's only a job, while I am studying', meaning that it's not their preferred career.

Hi 家伶. In most contexts, "work" and "job" are almost interchangeable. To analyze in more detail, work is pretty general. Job is a little more formal, implying a specific company/organization and set of tasks. Work is also tends to be used a little more informally, e.g., "I'm at work" or "I'm working". You would rarely if ever say "I am at my job". I work in the TV business (in general). I work at NTDTV, a specific company. Hope this helps. 作生意 (what a businessman does) 作貿易 (what a trader does)

Hello As for the difference between "trader" and "businessman" Mostly every "trader" is a businessman ,since he does commercial transaction involving trading goods . But not every "businessman" is a "trader" , because the word involves a a wider range of activities among them trading . A businessman includes also a broker , a manufacturer who both do trading too as part of their activity but not exclusively as in the trader's case .
