Zigbee is a wireless technology based on IEEE 802.15.4 standard which very well suits the unique needs of low cost, low power wireless IoT networks. It was created by the ZigBee Alliance which comprises of technology partners like Philips, Motorola, Intel and HP. It operates in the unlicensed band including 2.4 GHz, 900 MHz and … Read more
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

It has a broad area of study including the study of linear and nonlinear electronic devices, semiconductor devices, study of electromagnetic spectrum, and devices utilizing this spectrum for communication purposes. With … Read more
Today almost all electrical or electronic touch devices have a touchscreen display ranging from smartphones, tablets, smartwatches, ATM machines, gigantic industrial machine controller – almost everything which needs human interaction with the computer machine. You might be interested to know how does touch screen work? The first touchscreen was capacitive and was invented by E. … Read more
Deep Learning can be classified as the subset of Machine Learning which operates on neural network function inspired by human brain anatomy. It learns how humans learn i.e. through examples. It can learn from millions of unstructured and uncorrelated data which otherwise humans would take decades to learn. It can also be termed as a … Read more
Data mining is a process of filtering all the unwanted information and noise from the set of data points and make it useful for further processing. With the advent of the Internet of things and cloud, smart devices are able to generate a magnanimous amount of data. But all these overflooded data does not mean … Read more
Data Science is the science of analyzing raw data using statistics and machine learning techniques with the purpose of drawing insights from the data. In simple words, Data Science is the process of using data to find solutions/to predict outcomes for a problem statement. It is an interdisciplinary field that combines techniques and processes from … Read more
