Would Propane be considered a noxious fume?

Ever since my father had lit his propane heater I have been getting hiccups. The night he turned it on, the propane made me very sleepy, light headed, dizzy, and nauseous. I did not sleep in my room that night. The next day, I go to my boyfriend's grandmother's house with him and I find out she's been using her propane fireplace. I cannot seem to get rid of the hiccups. I don't drink too fast, nor eat too fast. Would it be the propane that is giving me the hiccups?

What is a computer system?

Computer system refers to the whole thing, all the components. Computer are made of three basic components you must always have, a CPU (or processor), a motherboard, and RAM (Random Access Memory). These components are what make the computer a computer. However, computers nowadays come with a series of extra equipment, called peripherals, which include the graphics card, the hard disk drive, etc. These are not necessary but if they happen to be in the computer they are also considered part of the computer system.
