IE9
It's simple, elegant and effective: back and forward buttons, a combined URL and search box with integrated close, refresh and compatibility mode buttons, your open tabs and then three icons for home, favorites and options.
The combined search and address bar can offer search suggestions, but unlike Chrome's suggestions it's something you have to opt into before your keystrokes are shared with remote servers.
Both Firefox and Internet Explorer feature hardware graphics acceleration, which promises to boost performance by getting your PC's graphics system to handle some of the heavy lifting. It's coming to Chrome too, but it hasn't made its way across from the developer channel yet.
IE9 is rather keen on its web applications, and in Windows 7 it introduces some clever new features to handle them. If you drag the icon from the current tab to the taskbar you can pin it just like any other program, and when you open it the browser buttons change colour to match the site - so for example if you pin Flickr you get blue browser buttons.
Most of the layout changes should be pretty obvious: the menu bar has been removed and the navigation controls / address bar are now at the forefront. We don't need to tell you that it looks a lot like Chrome – our guess is that Google's not exactly flattered by that since we're actually feeling the look of
IE9 more than the cartoony aesthetic of Chrome, but we realize that's a personal preference. The compatibility view, refresh and stop buttons have been just latched on to the address bar and there are dedicated favorite and tools buttons on the far right side.
IE9 has already received good positive reviews of its performance.

Standard of 802.11g
802.11g
In 2002 and 2003, WLAN products supporting a newer standard called 802.11g emerged on the market. 802.11g attempts to combine the best of both 802.11a and 802.11b. 802.11g supports bandwidth up to 54 Mbps, and it uses the 2.4 Ghz frequency for greater range. 802.11g is backwards compatible with 802.11b, meaning that 802.11g access points will work with 802.11b wireless network adapters and vice versa.
The 802.11g standard for wireless networking supports a maximum bandwidth of 54 Megabits per second (Mbps).
802.11g and other Wi-Fi network protocols include a feature called
dynamic rate scaling. If the wireless signal between two connected Wi-Fi devices is not strong enough, the connection cannot support a maximum speed of 54 Mbps. Instead, the Wi-Fi protocol reduces its maximum transmission speed to a lower number to maintain the connection.
It is fairly common for 802.11g connections to run at 36 Mbps, 24 Mbps, or even lower. When dynamically set, these values become the new theoretical maximum speeds for that connection (which are also even lower in practice due to the Wi-Fi protocol overhead described above).
Pros of 802.11g - fast maximum speed; signal range is good and not easily obstructed
Cons of 802.11g - costs more than 802.11b; appliances may interfere on the unregulated signal frequency

wireless of 802.11a
802.11a
While 802.11b was in development, IEEE created a second extension to the original 802.11 standard called 802.11a. Because 802.11b gained in popularity much faster than did 802.11a, some folks believe that 802.11a was created after 802.11b. In fact, 802.11a was created at the same time. Due to its higher cost, 802.11a is usually found on business networks whereas 802.11b better serves the home market.
802.11a supports bandwidth up to 54 Mbps and signals in a regulated frequency spectrum around 5 GHz. This higher frequency compared to 802.11b shortens the range of 802.11a networks. The higher frequency also means 802.11a signals have more difficulty penetrating walls and other obstructions.
Because 802.11a and 802.11b utilize different frequencies, the two technologies are incompatible with each other. Some vendors offer hybrid 802.11a/b network gear, but these products merely implement the two standards side by side (each connected devices must use one or the other).
The Pros of 802.11a - fast maximum speed; regulated frequencies prevent signal interference from other devices while the Cons of 802.11a - highest cost; shorter range signal that is more easily obstructed.

WiFi LAN of 802.11n
802.11n is a newer standard of WiFi LAN, or wireless local area network technology, subsequent to standards 802.11a, 802.11b and 802.11g. Its proper name is IEEE 802.11n, as it is a protocol developed by the international non-profit Institute of Electrical and Electronics Engineers. The number "11" indicates the IEEE working group assigned to 802 standards, and the "n" refers to a special task group within this body, known as TGn.
The IEEE 802.11n standard is scheduled to be reviewed by TGn in November 2005 and should debut in the marketplace sometime in mid-2006. It will reportedly offer quadruple the data transfer rates of the current fastest WiFi technology. It will also operate on the 2.4 gigahertz (GHz) band, like 802.11b and 802.11g. This frequency does not require line-of-sight availability like 802.11a, which works in the regulated 5 GHz band.
The newest IEEE standard in the Wi-Fi category is 802.11n. It was designed to improve on 802.11g in the amount of bandwidth supported by utilizing multiple wireless signals and antennas (called MIMO technology) instead of one.
When this standard is finalized, 802.11n connections should support data rates of over 100 Mbps. 802.11n also offers somewhat better range over earlier Wi-Fi standards due to its increased signal intensity. 802.11n equipment will be backward compatible with 802.11g gear.
Pros of 802.11n - fastest maximum speed and best signal range; more resistant to signal interference from outside sources
Cons of 802.11n - standard is not yet finalized; costs more than 802.11g; the use of multiple signals may greatly interfere with nearby 802.11b/g based networks.
The speed difference between 802.11n and the older 802.11g is only apparent on the local network in most cases. Internet speed is capped by whatever plan the user is on, and only the fastest plans are in excess of 25-54mbps, the limit of 802.11g. In other words, 802.11g is already many times faster than the average person's Internet connection.
Businesses/people that have their computers networked together (that's where you see the speed increase) *and* people who have Internet connections in excess of 25 mbps are the ones to benefit from 802.11n. Bear in mind the -average- Internet connection is about 1.5mbps for DSL and 5 mbps for cable. A *really* fast connection is 10mbps. Faster connections are certainly available but are pricey and are not what most people have.

Wireless N - 802.11b
Home and business networkers looking to buy wireless local area network (WLAN) gear face an array of choices. Many products conform to the 802.11a, 802.11b, 802.11g, or 802.11n wireless standards collectively known as Wi-Fi technologies. Additionally, Bluetooth and various other non Wi-Fi technologies also exist, each also designed for specific networking applications.
802.11bIEEE expanded on the original 802.11 standard in July 1999, creating the 802.11b specification. 802.11b supports bandwidth up to 11 Mbps, comparable to traditional Ethernet.
802.11b uses the same unregulated radio signaling frequency (2.4 GHz) as the original 802.11 standard. Vendors often prefer using these frequencies to lower their production costs. Being unregulated, 802.11b gear can incur interference from microwave ovens, cordless phones, and other appliances using the same 2.4 GHz range. However, by installing 802.11b gear a reasonable distance from other appliances, interference can easily be avoided.
* Pros of 802.11b - lowest cost; signal range is good and not easily obstructed
* Cons of 802.11b - slowest maximum speed; home appliances may interfere on the unregulated frequency band
Zyxel Releases Wireless N Access PointTaiwan based Zyxel Communications has introduced WAP 3205 wireless N compatible access point.
