There are a range of ways to buy bitcoins in your local area. Localbitcoins.com can be a good place to start if you just want to quickly get some bitcoins in your local currency.
The site can offer a range of ways to buy & sell bitcoins locally, but as always, they may range in trustworthiness. If you are worried, using a Bitcoin Exchange or web wallet service may be better.
A bitcoin exchange allows you to buy and sell Bitcoin in your local currency, as well as utilize a wide range of other transaction & speculation services for more advanced enthusiasts, traders, and investors. Due to security and government regulations concerning money laundering there is a short account verification process that new users are required to participate in for most exchanges.
Why use exchanges? Your Bitcoins are secure with a trusted and established exchange, and you can access more advanced trading features. However, exchanges are subject to more government regulation, and laws regarding Bitcoin have not yet been clarified in most markets. Also account verification means less account privacy.

A bitcoin web wallet is a tool that allows you to send & receive bitcoins. While some have more advanced features, they are not as in-depth as bitcoin exchanges and are designed as a way to send, receive, and manage Bitcoins much like a bank account. This also means that you should choose your web wallet like you would choose your bank.
Why use a Web wallet? Unlike desktop wallets, as the wallet is online you don't need to download the blockchain locally, freeing up space and CPU power on your PC. However, it's important to stay updated with your wallet service to be sure that they are operating legitimately. The vast majority are, but it's important to be aware.
A desktop wallet can be a more secure way of storing your bitcoins than a web wallet because the wallet is stored on your own computer. You can send, receive, and store your Bitcoins like an online wallet. A desktop wallet can also be encrypted, copied to multiple devices (such as USB sticks), and backed-up for security.
Why use a Desktop Wallet? More control and privacy in managing your funds. However, you must download and continually update the blockchain to perform transactions, which can take up a lot of hard drive space and CPU power, not to mention a long time to download.
