WiFi is the other name for wireless internet or a wireless network, and this name is often used by any technical users who only know how to access the Internet wirelessly, they know nothing beyond that. Wi-Fi is a short form mainly for wireless sincerity. Although many advanced users don't know these terms well, it is more known as Wifi. The term Wi-Fi is written in several ways which are, Wi-Fi, Wi-Fi, Wi-Fi, Wi-Fi, etc.
Wi-Fi was introduced by Wi-Fi alliance in 1985, it was a time when it was not used commercially but was only assigned to certain organizations for testing purposes. Wi-Fi Alliance is a leader in developing WiFi technology, and all Wifi-connected devices are highly supported by Wifi Alliance compatibility. The Wifi network was later properly developed, then often handled for public use in the USA in the 1990s, and the WIFI network gradually became the norms for most computer connections in countless organizations around the world
Wifi uses all networks that indicate any type of 802.11 network set by IEEE. IEEE is a short form of the Institute of Electrical and Electronic Engineering. There are many improvements made to 802.11, 802.11a, 802.11b, and other dual networks. The latest standard for the 802.11 family is 802.11y. Other well-known standards are 802.16, and these are the upcoming technology standards known as WiMax. There is one known group of Ethernet standards known as IEEE 802.3.
Wifi networks are still growing worldwide. This huge growth raises security problems. Wifi is the most widely used network worldwide and many organizations transfer their sensitive data using wireless networks. Increased use of the wireless network increases the security risks for users or the organization. A wireless network carries data of every kind, which can be normal data in pieces of information, or it can be encrypted or even very sensitive. WiFi security mechanism secures a certain level of data integrity and confidentiality and provides wired network. However, if appropriate security measures are not adopted, hackers can attack the network and this can cause significant damage not only to the users ’network but also to the users’ privacy.
There was a time when cables were used to connect multiple computers together. Devices such as routers, hubs, switches, etc., were needed to communicate between computers, but Wifi brought a high-tech change in computer connections by providing wireless connectivity features. It keeps things very simple without much hassle and can make networks easier. No wiring required. A wireless network keeps the environment very clean and clean. There are many other features of a wireless LAN, such as high-speed connection. Wifi provides high-speed connection and faster connections as the cables cannot be installed for example in remote areas. The list of Wifi features is long and includes some other key features that include site surveying, enterprise grade equipment, scalable systems, VPN compatibility, flexible authentication methods, guest satisfaction, end-user mobility and accessibility through hotspots.
WiFi supports two different types of modes; known to be infrastructure and one dedicated. In Ad Hoc Wireless connections can be made without a central device called a router or access point. Most network administrators prefer ad hoc over infrastructure. Custom how you have ever issues too. Wifi devices connected using the custom mode offer less protection against unauthorized users. Devices configured with ad hoc mode cannot disable SSID broadcasts unlike infrastructure mode, causing hackers to run, and using ad hoc mode is not difficult to spread on the wireless network. There are two main differences between these two modes: data transfer rate. The standard 802.11g wife network requires the dedicated connection mode to support 11Mbps bandwidth on the contrary, and supports 54Mbps data transmission using infrastructure mode. Therefore, the assigned situation is much slower than the infrastructure.
Existing wireless networks are increasing everywhere; every organization installs it if you haven't used it before. Some cities have already provided the entire city with WiFi and turn the city into a hotspot, a great example ahead of us Chicago. Chicago has installed a massive dish-sized transmitter from Wifi that broadcasts wireless signals to a wireless LAN across the city. It provides high-speed internet connection at a very cheap price. Laptops, desktop computers, PDAs and other devices installed on the wireless LAN card can access the network and have a high-speed connection on the go. WiFi users are increasing day by day, so their device manufacturers manufacture products on a large scale. These products are readily available on the market at an affordable cost. Laptops, PDAs and motherboards for the latest desktop computers come in the form of wireless LAN cards. If it is not already installed on the laptop, you can purchase the PCMCI slot wifi card to install to access the wireless network. Wifi PCI cards are also widely available in the market. Now USB wifi is also available in the short term but it still works fine.
Smart routers are available on the market that connect different devices to the wireless network. These routers can be configured with or without a computer. All that is needed to connect the Internet cable to an Ethernet or USB port to the appropriate routing port. When the Internet is available for routers, it can be configured using its control panel using IP 192.168.1.1. This is where we can enable or disable SSID broadcasting and perform other functions. Computers can also be connected to routers for more advanced management that routers cannot implement. It is often required to use personal computers where the network is huge and maintaining its integrity and stability is extremely important.
In this modern era, everyone wants everything wirelessly, Wifi belongs to the family of wireless technology. There are many other wireless technologies that have evolved over time, WiFi is now taken for granted and the world is now talking about an advanced and improved wireless network known as WiMax. WiMax outperforms Wifi in many rules that include the speed at which the data rate is transmitted, the range to which it is connected and much more. Now we have to see when WiMax will take over WiFi, and which technology will eventually get WiMax. One thing is for sure, the latest technology in wireless technology will continue to emerge and will continue to appear with a new look.
