This document discusses wireless networking. It defines wireless networking as transferring data between devices without wires or cables using technologies like radio transmission. It describes the components needed for a wireless network like antennas and wireless adapters. It categorizes wireless networks into LANs, MANs, WANs and PANs based on their size and range. It also discusses security options and standards for wireless networks like WEP, WPA, and WPA2. Finally, it outlines advantages like improved access and mobility and disadvantages like potential security issues and fluctuating transmission speeds.

Wi-Fi Network connect computers to each other, to the internet and to the wired network.
Wireless Technology is an alternative to Wired Technology, which is commonly used, for connecting devices in wireless mode.
The term Wi-Fi, first used commercially in August 1999.
Freedom – You can work from any location that you can get a signal.
Setup Cost – No cabling required.
Scalable – Can be expanded with growth.
Mobile Access – Can access the network on the move.
Wireless Intelligent Network is a concept developed by the TR-45 Mobile and Personal Communications Systems Standards engineering committee of the Telecommunications Industry Association.
A Simple presentation on Wi-Fi Technology. For all non-technical individuals for personal knowledge and information. Made for MIS (Management Information System) Subject in MBA (Masters in Business Administration)

Wireless networks are computer networks that are not connected by cables of any kind. Using this technology we can establish network which is more flexible, intangible and easy to access.
SECURING IEEE 802.11G WLAN USING OPENVPN AND ITS IMPACT ANALYSISIJNSA Journal
Like most advances, wireless LAN poses both opportunities and risks. The evolution of wireless networking in recent years has raised many serious security issues. These security issues are of great concern for this technology as it is being subjected to numerous attacks. Because of the free-space radio transmission in wireless networks, eavesdropping becomes easy and consequently a security breach may result in unauthorized access, information theft, interference and service degradation. Virtual Private Networks (VPNs) have emerged as an important solution to security threats surrounding the use of public networks for private communications. While VPNs for wired line networks have matured in both research and commercial environments, the design and deployment of VPNs for WLAN is still an evolving field. This paper presents an approach to secure IEEE 802.11g WLAN using OpenVPN, a transport layer VPN solution and its impact on performance of IEEE 802.11g WLAN.

Bills have a main role in point of sale procedure. It will help to track sales, handling payments and giving receipts to customers. Bill splitting also has an important role in POS. For example, If some friends come together for dinner and if they want to divide the bill then it is possible by POS bill splitting. This slide will show how to split bills in odoo 17 POS.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
2. What is Wireless Networking?
With the help of wireless
technology we can transfer data
from one device to another
without using wire or cables.
Using this technology we can
establish network which is more
flexible, intangible and ease to
access.
4. Components Requirements
The important components required for
setting up a wireless network are:
Medium
Access point and Extension point
Wireless bridges and Power line
bridges
Antennas
Wireless adapters
Wireless Station and Server
Software
6. Types of Wireless Networks
Based on the size Wireless Networks are
divided into four categories .
Wireless LAN
Wireless MAN
Wireless WAN
Wireless PAN
7. Wireless LAN
This is a network where two or more
computers are connected that covers only a
limited area.
The NIC ( Network Interface Card)is used in
this connection where has a small range to
cover.
We often called this peer to peer Network.
8. Wireless MAN
Collected unit of many WLAN located at
various.
It uses WIMAX(World wide Interoperability
for Microwave Access) which is controlled by
WiMAX Forum.
Maximum speed 1Bits/sec.
9. Wireless WAN
WWAN is a very large network which is spread
over a very large area. It connects many cites
together.
The technology in WWAN are subdivided in
many generations: 2G, 3G, 4G.
This technology used in most of the Analog
devices.
10. Wireless PAN
The Wireless Networks that are used in
smaller distance are know as WPAN.
The communication between a mobile phone
and its Bluetooth headset.
Two kinds of Wireless technologies are used
for WPAN.
Bluetooth and Infrared Data Association.
12. Security Options in Wireless
Network
Data can be easily hacked in Wireless network without
using proper security.
Three commonly used security system:
1. Wired Equivalent Privacy(WEP)
2. Wi—Fi Protected Access(WPA)
3. Wi—Fi Protected Access(WPA2)
13. WEP:
1. Security standard released in 1997.
2. The Encryption Algorithm used in WEP was easily
Breakable by Hackers.
WPA
1. Released in 2003, Invented by Wi—Fi Alliance
2. Required Firmware up gradation instead of changing any
hardware component.
WPA2
1. Released in 2004
2. Advanced security features are available
3. Advanced Encryption Standard
14. Why we use wireless
Networking?
It is helpful for portable devices such as
Laptops, mobiles, tablets etc.
Establish a network connection is easy.
Introducing a new device in the
Network is easy.
Security system is more featured in
wireless Networks.
