iPhone, The World's 1st Real PC - The new 3G Apple iPhone was released recently, to an audience who were pretty much on the edge of their seats with anticipation. The reviews have been largely favourable, with many bordering on zealous, such as the review by Alex Iskold on Read Write Web. In the review, which really isn't all that long, Iskold manages to tell us seven times that the iPhone is the new personal computer. In fact, according to Iskold, the new iPhone is the world's first really personal computer, and he seems pretty excited about that.
How to Connect Two Laptops Using Bluetooth - Do you need to copy a heavy file from another laptop without using pen drive or connecting cables? Of course, this can be done by using electronic transfer methods like ftp or online data storage systems. However, these methods are not only time consuming, they often lead to increased data transfer costs. Moreover, what if there is no internet connectivity available in the immediate vicinity? Under such circumstances, you can connect two laptops through Bluetooth and exchange files seamlessly.
Comparing Apples and Androids - When the iPhone made its debut on June 29, 2007 the world went crazy. People lined up for blocks, camped out on sidewalks for days just to be the first to get their hands on the phone that would change their lives forever. However in 2009 iPhone 3G (3g Phone) was released and the mayhem started over. The iPhone seemingly had cornered the Smartphone market in spite of its hefty price tag of $600. Of course the price dropped significantly and those who waited could purchase the iPhone for under a $100.
But ... lurking in the shadows was a phone which would give the iPhone a run for its money. It was similar in style to the iPhone and could be customized to suit the user’s needs—the Droid. T-mobile launched the Google phone or the G1 was officially in the hands of gadget lovers on October, 2008. The G1 was the first to use the Google Android software and cost a mere $179 with a 2 year contract. T-Mobile allowed customers to pre-order the phone to ensure customers had the phone in hand on the official release date.
History of TCP/IP - Internetworking with TCP/IP has been around for many years-almost as many years as Unix has been available. TCP/IP, or Transmission Control Protocol/Internet Protocol, grew out of the work that was done with the Defense Advanced Research Projects Agency, or DARPA. In 1969, DARPA sponsored a project that became known as the ARPANET. This network mainly provided high-bandwidth connectivity between the major computing sites in government, educational, and research laboratories.
IP Spoofing and Sniffing - Sniffing and spoofing are security threats that target the lower layers of the networking infrastructure supporting applications that use the Internet. Users do not interact directly with these lower layers and are typically completely unaware that they exist. Without a deliberate consideration of these threats, it is impossible to build effective security into the higher levels. Sniffing is a passive security attack in which a machine separate from the intended destination reads data on a network. The term "sniffing" comes from the notion of "sniffing the ether" in an Ethernet network and is a bad pun on the two meanings of the word "ether." Passive security attack are those that do not alter the normal flow of data on a communication link or inject data into the link.
Brief History of Wi-Fi - Wi-Fi would certainly not exist without a decision taken in 1985 by the Federal Communications Commission (FCC), America's telecoms regulator, to open several bands of wireless spectrum, allowing them to be used without the need for a government license. This was an unheard-of move at the time; other than the ham radio channels, there was very little unlicensed spectrum. But the FCC, prompted by a visionary engineer on its staff, Michael Marcus, took three chunks of spectrum from the industrial, scientific and medical bands and opened them up to communications entrepreneurs.
What is WIFI?
Wireless Fidelity – popularly known as Wi-Fi, developed on IEEE 802.11 standards, is the recent technology advancement in wireless communication. As the name indicates, WI-FI provides wireless access to applications and data across a radio network. WI-FI sets up numerous ways to build up a connection between the transmitter and the receiver such as DSSS, FHSS, IR – Infrared and OFDM. The development on WI-FI technology began in 1997 when the Institute of Electrical and Electronic Engineers (IEEE) introduced the 802.11 technology that carried higher capacities of data across the network. This greatly interested some of major brands across the globe such as the world famous Cisco Systems or 3COM. Initially, the price of Wi-Fi was very high but around in 2002, the IT market witnessed the arrival of a break through product that worked under the new 802.11 g standards. In 2003, IEEE sanctioned the standard and the world saw the creation of affordable Wi-Fi for the masses.
Wi-Fi provides its users with the liberty of connecting to the Internet from any place such as their home, office or a public place without the hassles of plugging in the wires. Wi-Fi is quicker than the conventional modem for accessing information over a large network. With the help of different amplifiers, the users can easily change their location without disruption in their network access. Wi-Fi devices are compliant with each other to grant efficient access of information to the user. Wi-Fi location where the users can connect to the wireless network is called a Wi-Fi hotspot. Through the Wi-Fi hotspot, the users can even enhance their home business as accessing information through Wi-Fi is simple. Accessing a wireless network through a hotspot in some cases is cost-free while in some it may carry additional charges. Many standard Wi-Fi devices such as PCI, miniPCI, USB, Cardbus and PC card, ExpressCard make the Wi-Fi experience convenient and pleasurable for the users. Distance from a wireless network can lessen the signal strength to quite an extent; some devices such as Ermanno Pietrosemoli and EsLaRed of Venezuela Distance are used for amplifying the signal strength of the network. These devices create an embedded system that corresponds with any other node on the Internet.
The market is flooded with various Wi-Fi software tools. Each of these tools is specifically designed for different types of networks, operating systems and usage type. For accessing multiple network platforms, Aircrack-ng is by far the best amongst its counterparts. The preferred Wi-Fi software tools list for Windows users is: KNSGEM II, NetStumbler, OmniPeek, Stumbverter, WiFi Hopper, APTools. Unix users should pick any of the following: Aircrack, Aircrack-ptw, AirSnort, CoWPAtty,Karma . Whereas, Mac users are presented with these options: MacStumble, KisMAC, Kismet. It is imperative for users to pick out a Wi-Fi software tool that is compatible with their computer and its dynamics.
