Can we connect a pc which has only VGA port (no graphics card available) and a TV with only HDMI port?
If a VGA to HDMI converter is the solution, is it equivalent to a graphics card? Also what is the lowest budget for this? Why do people prefer VGA to HDMI converter when they can buy a graphics card which supports HDMI (I think cost for both VGA to HDMI converter and graphics card is nearly the same)?

Your computer has an on-board VGA card. Using a VGA to HDMI cable is only converting the signal. It is not a graphics card on its own, so all performance you have over the normal VGA port is what you'll see on the TV.
It is either this cable (its cheap) or an extra Graphics Card with HDMI support (expensive, but depending on what you want, may be the only choice)
The reason people prefer VGA to HDMI convertors is because the prices are very cheap considering what an actual GPU costs. Usually those people have a GPU that is already good, and getting a low priced GPU with HDMI will reduce performance significantly. Also, not everyone has room for an additional GPU.
