Often many of us get confused with the two similar terminologies “Wi-Fi” and “Wi-Fi Direct”. Wi-Fi Direct is similar to Wi-Fi technology except that the devices can connect and transfer data directly without the need of having being connected to a wireless Access Point (router or modem). It is also an IEEE 802.11 standard defining … Read more
Wi-Fi is the wireless networking technology that connects the device with the Internet. Rather than using wires it uses radio waves to transmit information. Wi-Fi stands for Wireless Fidelity. When an antenna receives this radio wave, an electromagnetic field is created which can travel through space. It is based on IEEE 802.11 family of standards. … Read more
Wired Communication implies transmission of data from the transmitter to the receiver end point over a wired physical medium. Examples of wired communication includes Telephone lines and Television transmission system. It may use devices like ethernet, RS-232 or RS-485 cables or Universal Serial Bus (USB) for data transmission. It is advantageous to use Wired Communication … Read more
Wireless Communication is basically the technology where electromagnetic radio waves can be transmitted from one point to another. It eliminates the need of devices being connected with any physical medium like wires, cables or optical fibres as in case of Wired communication. With the wireless communication technology information can be passed on to a distant … Read more
Internet of Things (IoT) is the networking of smart devices (electronics, mechanical and digital machines) that have unique identifiers that can collect data from the external world through sensors and feed them to databases for further processing. The advancements made in the IoT domain in recent years have changed the level of services they offer … Read more
