Raspberry pi zero

friends this is one of the most smallest computer in a single bord. it is basically use in iot projects. but don't miss judge it by its small size. it has- 1ghz single-core CPU 512 mb ddr2 ram mini hdmi and usb on-the-go ports Micro USB power 51 HAT-compatible 40-pin header but most ineradicable part of it is, it cost only 5 dollars (us). <uses> you use this as a adrino bord in any development projects. it is also use a test kit to hackers and panitration testers. and also as a most compact or handy pc. but i gonna use this bad boy as my tiny pc.

HOW WIFI WORKS?

WHAT IS WIFI:- It may happen that now you are connected to a wifi router and surfing the internet through that.But did you know how the data is displaying in your computer or phone's display? when your device is not connected with any of physical connecting wire. The wifi is basically an electromagnetic radiation, just like the microwave, visible light or the gamma rays but the only difference is the use, the frequency and wives length of that radiation. Wifi signals basically use the two bands 2.4 or 5 GHz. And it basically transmits the data in the form of 0 and 1. The wifi signal uses the same concept of a radio F.M but this communication is two way. HOW IT REALLY WORKS:- The wifi networks basically break the data in small encrypted packets and send back and forward between your router and portable device. The packets also have the address of the destination node and the decryption key. And after the data is received by your device t...
