If you buy a Long Call, you are buying the right to purchase the stock at a given price. and you want the price to rise so you can purchase the stock at the cheaper price. If you buy a Long Put, you are buying the right to sell the stock at a given price and you want the price to drop so you can sell at a higher price than the market. In both instances, you can only lose what you paid for this right if the underlying price goes against you. Think of this like buying insurance.
If you are short a call, you are selling someone else the right to buy that stock at a given price. Conversely if you are short a put, you are selling someone the right to sell the stock at a given price. In the case of a short put, you lose if the stock price drops as someone will execrcise their right to sell at the higher price. if you are short a call, you lose if the stock goes up because someone will exercise their right to buy at a cheaper price. Think of short options as selling insurance. Short puts have the risk of the underlying going to zero while short calls have unlimited risk as the price can rise infinitely.
Play around with paper trading some simple calls and puts, see how the price reacts, see how implied volatility and time decay affect your positions. I agree with the other posters to not put any real money on the line until you have the basics down cold.
