The document provides an overview of recent trends in networking, including Local Area Networks (LAN), Wide Area Networks (WAN), Bluetooth, Wi-Fi, Zigbee, and concludes with a thank you and bibliography. It discusses LAN as a high-speed network within a building or campus, and WAN as a network covering a broader geographic area. It also provides technical details and comparisons of Bluetooth, Wi-Fi, and Zigbee wireless technologies.

6. Networks - A Small intro… Networking allows one computer to send information to and receive information from another. Certainly the Internet is the most conspicuous example of computer networking. Allows many different devices in multiple locations to access a shared repository of data

7. LAN Within a Building or Campus A high-speed data network that covers a relatively small geographic area . It typically connects workstations, personal computers, printers , servers , and other devices .

8. What Is a WAN? Network that covers a relatively broad geographic area WAN technologies generally function at the lower three layers of the OSI reference model: the physical layer, the data link layer, and the network layer. WAN (Wide Area Networking) A Typical Point-to-Point Link Operates Through a WAN to a Remote Network:

19. Wireless Fidelity (Wi-Fi) Welcome to the World of Wireless Short form of Wireless Fidelity. This can be defined as a wireless Local Area Networking System. Can you imagine a day without Internet ? For me it is not possible. That means now internet has become an integral part of our life. With the help of Wi-Fi, we can access broad band internet connection with high data transfer rate. The main attractive feature of this technology is that it can provide wireless broadband connection within a specific geographic boundary.

22. Products

23. Wireless Fidelity (Wi-Fi) We can access internet through our laptop . Because of this WiFi technology tourism contacts is being progressed. So Wi-Fi is rocking. Isn't it?

24. Wireless Fidelity (Wi-Fi) Advantages Mobile. Widely available in public venues. Relatively inexpensive. Easy to set up a network. User-friendly software. Security features. Global set of standards.

25. How to use WiFi? Host Wireless Router Network adapter Network name Network password

26. Wi-Fi Security WEP stands for Wired Equivalency Privacy As its name implies, this standard was intended to make wireless networks as secure as wired networks. The common key lengths are currently 128- and 256- bit. WPA Wi-Fi Protected Access is an early version of the 802.11i security standard that was developed by the Wi-Fi Alliance to replace WEP.

27. Created by the ZigBee Alliance Technological Standard Created for Control and Sensor Networks Low data rate Low power consumption Small packet devices
