From today's featured articleWipeout 3 is a racing video game developed by Psygnosis and published by Sony Computer Entertainment for the PlayStation console, first released on 8 September 1999. In this third game in the Wipeout series, players control extremely fast anti-gravity ships in a futuristic setting and use weapons to force other contenders out of the race. Psygnosis hired the British design studio Designers Republic to develop the game's look and feel, wanting a futuristic yet plausible setting. The game's soundtrack was assembled from electronica artists including The Chemical Brothers and Orbital, as well as other performers. Critics praised Wipeout 3's audiovisual presentation, with complaints leveled at the game's unforgiving learning curve and controls. Despite overall positive reception, the game was a financial disappointment. Wipeout 3 Special Edition, featuring additional content, was released in 2000, and the next entry in the series, Wipeout Fusion, was released for the PlayStation 2 in 2002. (Full article..)

Today's featured picture
The 2017 Atlantic hurricane season was a hyperactive tropical cyclone season and the costliest on record, with a damage total of at least $282.02 billion (2017 USD). Featuring 17 named storms, 10 hurricanes and 6 major hurricanes, 2017 had the fifth-most named storms since reliable records began in 1851 – tied with 1936 – and the most major hurricanes since 2005. Collectively, the tropical cyclones were responsible for at least 3,364 deaths – the most fatalities in a single season since 2005. Most of the season's damage was due to hurricanes Harvey, Irma and Maria. Another notable hurricane, Nate, was the worst natural disaster in Costa Rican history. The names Harvey, Irma, Maria and Nate were retired following the season due to the number of deaths and amount of damage they caused. This season is also one of only six years on record to feature multiple Category 5 hurricanes and the only season other than 2007 with two hurricanes making landfall at that intensity. All ten of the season's hurricanes occurred in a row – the greatest number of consecutive hurricanes in the satellite era, and tied for the highest number of consecutive hurricanes ever observed in the Atlantic basin. A hyperactive season, 2017 had the highest accumulated cyclone energy (ACE) since 2005, while a record three hurricanes each had an ACE of over 40: Irma, Jose and Maria. This picture, taken by the VIIRS instrument on the National Oceanic and Atmospheric Administration's Suomi NPP satellite on September 8, 2017, shows three hurricanes simultaneously active in the western Atlantic: Katia(left) making landfall in the Mexican state of Veracruz, Irma (center) approaching Cuba, and Jose(right) northeast of the Leeward Islands at peak intensity.

Introduction
A wireless local area network (WLAN) is a local areanetwork (LAN) that doesn't rely on wired Ethernetconnections. A WLAN can be either an extension to a current wirednetwork or an alternative to it.
WLANs have data transfer speeds ranging from 1 to 54Mbps, with somemanufacturers offering proprietary 108Mbps solutions. The 802.11nstandard can reach 300 to 600Mbps.
Because the wireless signal is broadcast so everybody nearby canshare it, several security precautions are necessary to ensure onlyauthorized users can access your WLAN.
A WLAN signal can be broadcast to cover an area ranging in sizefrom a small office to a large campus. Most commonly, a WLAN accesspoint provides access within a radius of 65 to 300 feet.
WLAN types
Private home or small business WLAN
Commonly, a home or business WLAN employs one or two access pointsto broadcast a signal around a 100- to 200-foot radius. You can findequipment for installing a home WLAN in many retail stores.
With few exceptions, hardware in this category subscribes to the802.11a, b, or g standards (also known as Wi-Fi); some homeand office WLANs now adhere to the new 802.11n standard. Also, becauseof security concerns, many home and office WLANs adhere to the Wi-FiProtected Access 2 (WPA2) standard.
Enterprise class WLAN
An enterprise class WLAN employs a large number of individualaccess points to broadcast the signal to a wide area. The accesspoints have more features than home or small office WLAN equipment,such as better security, authentication, remote management,and tools to help integrate with existing networks. These accesspoints have a larger coverage area than home or small officeequipment, and are designed to work together to cover a much largerarea. This equipment can adhere to the 802.11a, b, g, or n standard,or to security-refining standards, such as 802.1x and WPA2.
WLAN standards
Several standards for WLAN hardware exist:
| WLAN standard | Pros | Cons |
|---|---|---|
| 802.11a |
|
|
| 802.11b |
|
|
| 802.11g |
|
|
| 802.11n | The 802.11n standard was recently ratified by theInstitute of Electrical and Electronics Engineers (IEEE), as compared to theprevious three standards. Though specifications may change, it isexpected to allow data transfer rates up to 600Mbps, and may offerlarger ranges. | |
Security standards
The 802.11x standards provide some basic security, but are becomingless adequate as use of wireless networking spreads. Following aresecurity standards that extend or replace the basic standard:
WEP (Wired Equivalent Privacy)
WEP encrypts data traffic between the wireless access point and theclient computer, but doesn't actually secure either end of thetransmission. WEP's encryption level is relatively weak (only 40 to128 bits). Many analysts consider WEP security to be weakand easy to crack.
WPA (Wi-Fi Protected Access)
WPA implements higher security and addresses the flaws in WEP, butis intended to be only an intermediate measure until further 802.11isecurity measures are developed.
802.1x
This standard is part of a full WPA security standard. WPA consistsof a pair of smaller standards that address different aspects ofsecurity:
- TKIP (Temporal Key Integrity Protocol encryption), which encryptsthe wireless signal
- 802.1x, which handles the authentication of users to the network
Commonly, wireless systems have you log into individual wirelessaccess points or let you access the wireless network, but then keepyou from accessing network data until you provide furtherauthentication (e.g., VPN).
802.1x makes you authenticate to the wireless network itself, notan individual access point, and not to some other level, such asVPN. This boosts security, because unauthorized traffic can be deniedright at the wireless access point.
WPA2/802.11i
The Wi-Fi Alliances coinedthe term 'WPA2' for easy use by manufacturers, technicians, and endusers. However, the IEEE name of the standard itself is802.11i. The encryption level is so high that it requires dedicatedchips on the hardware to handle it.
In practical use, WPA2 devices have interoperability with WPAdevices. When not interfacing with older WPA hardware, WPA2 deviceswill run strictly by the 802.11i specifications. Castlevania harmony of despair xbox.
WPA2 consists of a pair of smaller standards that address differentaspects of security:
- WPA2-Personal, which uses a pre-shared key (similar to a single password available to groups of users, instead of a single individual); the pre-shared key is stored on the access point and the end user's computer
- WPA2-Enterprise, which authenticates users against a centralizedauthentication service

IU Secure, the new IU wireless network for students,faculty, and staff, uses WPA2 Enterprise for authentication.
