What is Wi-Fi ?

Wi-Fi stands for (Wireless Fidelity)

Wi-fi is a technology that allows you to connect devices and computers to the internet. Wi-fi is also referred to as wireless local area network or WLAN. It can be used for many different purposes like communication, sharing files and data, storing information and even playing games.

Wi-fi can be provided by your home Wi Fi router or by public Wi-Fi hotspots. In most cases, it is not necessary for you to purchase a WiFi router because you can use your existing WiFi network with the help of a Wi-Fi app.

Who invented Wi-Fi?

A wireless network called ALOHAnet was created in 1971 that connected the Great Hawaiin islands. Ethernet and Wi-Fi can trace some of their history back to that.

But it was in 1991 that NCR Corporation (which began as a cash register company) and AT&T (which began as a phone company) created the precursor to Wi-Fi as a way of linking cash registers called WaveLAN.

It became so popular that eventually the Institute of Electrical and Electronics Engineers (IEEE) created the 802.11 standard that we now know as Wi-Fi. In 1999, the Wi-Fi Alliance formed as a trade association to hold the reins of the Wi-Fi trademark.

Basics of Wi-Fi!

Wi-Fi is a technology that is used to connect devices in a network. It is used in almost all electronic devices and it’s very common in the modern world. The Wi-Fi technology has been developed by many companies and it’s pretty easy to understand how it works.

Wi-Fi can be described as an abbreviation of “Wireless Fidelity” or “Wired for Home”. It’s just another name for radio waves that travel through the air (or through space). When you want to connect two devices together, you need to use this technology. There are different types of Wi-Fi, such as IEEE 802.11b, 802.11g, 802.11n etc.. All of them have one thing in common – they are all based on radio signals and they transmit information automatically.

Radio waves can be transmitted over short distances with high speeds (on the same frequency).So, when you connect your device to a Wi-Fi network, it will automatically be chosen in order to transmit wireless signals. Consequently, the Wi-Fi signal is weaker than the one generated by radio waves in normal conditions therefore, it must be either turned on or off respectively to increase the geographical range of the signal.

How does Wi-Fi works?

Wi-Fi is a technology that allows you to connect to the internet without wires. It can be used in many places and for many purposes.

Wi-Fi works by using radio waves, which are transmitted from one location to another, and received by a receiver at the other end of the wire.

The receiver uses this information to send out signals that can be received by other devices. These signals are then processed and sent on to the next device or router that is located in between them.

This process continues until it reaches the destination device or router at which point it is processed again for transmission on to another device or router along its path. At each step of this process, there are two things happening; one thing being a sender sending out signals and receiving signals back while at the same time another thing being the receiver receiving signals and being able to integrate those signals back into some sort of conscious state.

Different Types of Wi-Fi connections

Wi-Fi is a technology that allows users to connect to the internet and transfer data. It has become a very popular way of communicating and sharing information over the internet.

Wi-Fi connections are divided into three types:

  1. Wi-Fi Protected Access (WPA) : Wi-Fi Protected Access (WPA) is a standard for encryption of the wireless network. The WPA protocol is based on the IP protocol and it is used in a variety of applications including Wi-Fi networks, WiMAX, mobile Internet devices, fixed line telephone systems and home or office broadband connections.
  2. Wi-Fi Protected Setup (WPS) : WPS is a wireless security standard, which has become mandatory by the FCC. It is a secure way to lock and unlock your Wi-Fi password. As of today, WPS has been adopted by over 8 million devices, including smartphones and tablets with Android OS. WPS connects to a wireless access point by using a PIN or password, while WPA connects without any password at all.
  3. Wi-Fi Direct: Wi-Fi Direct is an option for connection between two devices that does not require passwords or PINs. It is used when one device wants to connect directly with another device which does not require authentication.

Wi-Fi Security for Businesses & Home Users

Security is a very sensitive topic. Every business and home needs to protect their data, devices and people from hackers and cybercriminals. The security of your network is important for all kinds of businesses, both large and small.

Businesses can use Wi-Fi security to protect their data from hackers and intruders. They can also use it to keep track of the amount of data that is being sent over the network. The best part is that they don’t need an expensive network or a lot of technical expertise to set up and maintain Wi-Fi security in their offices.

Wi-Fi security provides businesses with a secure connection between the devices on the network and each other, while also preventing unauthorized access by other users on the network. It’s not hard to set up, but it does require some technical knowledge in terms of hardware setup, software setup and configuration as well as setting up some policies for how much data is allowed to be transferred and how many data packets you want to transfer at once.
