Call Option - A contract that gives the buyer the right, but not the obligation, to purchase a specified amount of underlying security at a strike price anytime before the contract expires (if it is American style option) or at expiration only (if it is European style option). The call option buyer hopes the price of the shares will rise by a specific date while the put option seller hopes that the price of the shares drop or remain stable by the specified date.

For example: I write a call option with 100 Microsoft shares, strike at $35 and expiration date in July. Now I have an obligation to fulfill the terms of the contract. I get some money for this contract and I hope that price will be no more then $35. But if you as option buyer exercise contract I must sell you 100 Microsoft shares at $35 for each.

Put Option - An option contract giving the owner the right, but not the obligation, to sell a specified amount of an underlying security at a strike price within a specified time.

For example: I write a putt option with 100 Microsoft shares, strike at $35 and expiration date in July. I get some money for this contract and I hope that price will be no less then $35. But if you as option buyer exercise contract I must buy from you 100 Microsoft shares at $35 for each.
