A hard drive, or hard disk drive (HDD), is the storage device you use in your personal computer (PC). These are non-volatile storage devices used to store the data of your computermeaning you can be assured that whatever data is stored in these devices, it cannot easily be erased. However, there is no guarantee that your HDD would not encounter problems causing it to crash and causing you to eventually loose your data.

Inside the HDD, there are many mechanisms that move around to perform read and write functions. The HDD is made of rotating platters, commonly called disks. Each of these platters has a planar magnetic surface where the data is stored. This data is sent to a read-write head, which sends an electrical charge, executing the transaction. These moving parts and electrical charges could possibly cause the breakdown of your HDD, but manufacturers have already designed firmware into the HDD to allow more efficient scheduling of reads and writes if the HDD surface and the remapping of sectors of the disk fail. Also, HDD manufacturers have collaborated with motherboard makers in developing the Self-Monitoring, Analysis, and Reporting Technology, or S.M.A.R.T., that can warn you of possible failures, allowing you to make necessary backups before data loss occurs.

An HDD is accessed with the following bus types: ATA (which includes IDE and EIDE), SATA, SCSI, SAS, FireWire (or IEEE 1394), USB and Fibre Channel. Aside from the connection, you have to select your HDD by the capacity, nowadays measured by gigabytes; the physical size, normally, if you are using a desktop, you would need a 3.5 HDD, whereas 2.5 is what you would use for a laptop; the reliability or the estimated number of uses before you HDD fails; speed or the number of reads and writes per second; power consumption; transfer rate; random access time; and the G-shock rating, which is very important if you plan to travel with your HDD a lot.

As the battle of the handheld gaming systems hots up, one of the emerging must-haves is proving to be the capability of Wi-Fi gaming. As the term implies, Wi-Fi gaming involves playing games via a Wi-Fi internet connection to other players. The two most popular handheld gaming consoles, the PlayStation Portable (PSP) and the Nintendo DS, both allow Wi-Fi gaming, across the PlayStation Network and the Nintendo Wi-Fi Network, respectively.

Wi-Fi gaming allows users to compete against others connected to the internet nearby or even on the other side of the world. Even if you don't have friends who have an interest in gaming, with 53 million Nintendo DS consoles and 25 million PSP consoles sold worldwide, it is unlikely that there won't be anyone to play against, regardless of your preferred gaming genre.

Wi-Fi networks are accessible within the transmitting range of a wireless access point, or hotspot. In the US, the city of Albuquerque, New Mexico, has gone as far as to offer free Wi-Fi access to all of its residents. In the UK, Norwich is pioneering a free city-wide Wi-Fi project, employing 200 antennas to cover the city centre and three sectors of the city. Similar projects are being planned for other major UK cities, such as Manchester, London and Birmingham. For those not lucky enough to live in a city with a comparable scheme there are several free Wi-Fi connections in cafs, pubs and public places such as airports, and Nintendo have even struck a deal with McDonald's in order to provide designated Wi-Fi access for the Nintendo Wi-Fi Network. In the UK there are currently 7500 branches offering this facility.

For those who prefer gaming at home, in addition to the handheld consoles, the latest-generation home consoles, that is, the Nintendo Wii, the PlayStation 3 and the Xbox 360 can all access the internet for gaming via Wi-Fi connections, although the Xbox 360 will require the optional USB Xbox 360 Wireless Networking Adapter to go wireless.

The range of games available for the handheld consoles for online play should be wide enough to suit anyone's tastes. There's role playing games such as Final Fantasy III and Zelda: The Phantom Hourglass, first-person shooters like Tom Clancy's Rainbow Six: Vegas, racing games such as Mario Kart DS and sports games, including FIFA 08 to name but a few. The opportunities are literally endless, and with the market for online gaming set to increase from $5.9bn in 2007 to $13bn by 2012 according to research by the DFC Intelligence Group, that is unlikely to change anytime soon.

So with an almost limitless amount of places to play the games, people to play with and game genres, gamers are simply spoilt for choice by the current wave of Wi-Fi gaming.
