Abstract : Wifi is a wireless technology that allows devices to connect to each other without the use of wires. So it is easy to join additional devices to a wifi network without having to trail cables around your house, it is considered far more convenient than a wired connection. Furthermore, at an age when many devices are portable, wifi allows users to stay connected regardless of where they are on the network. This allows you to use the same gadget in different parts of your house. Nowadays, most devices connect to the internet via WiFi. In fact, wifi networks will be available in most hotels, cafes, restaurants, offices, school, colleges and many households. These networks, especially the ones observed in and across the home, are regularly constructed around a single router that hyperlinks to more than one computers. A Raspberry Pi is a general-purpose computer which connected with wifi that typically runs a Linux operating system and can run multiple programmes. Raspberry Pi serves as the brain. Its main advantage is higher level processing capability. It's a single-board computer. A single-board computer (SBC) is a complete computer built on a single circuit board, complete with microprocessor(s), memory, input/output (I/O), and other functional computer features. Single-board computers were created for use as demonstration or development systems, educational systems, or embedded computer controllers. Many home computers and portable computers combine all of their functions on a single printed circuit board. The Raspberry Pi includes an on-board 802.11n Wireless LAN adapter, eliminating the need to purchase a separate WiFi dongle. It's also a lot easier to set up.
