  Hazardous diseases of modern time. The whole world is experiencing the modernity of 21st century, multiple advancements/improvement has already taken place in almost all the field to improve the standard of living and providing the ease of work to the people by innovating the new and the better technology,but with stepping toward the modern time we had already experienced multiple deadliest Disease/Pandemic in the past and this continuation is not over yet. When we look into the past   we realise that how much dangerous the modern time is for the human life, if we are talking about most deadliest Pandemics then how can we forgot the HIV/AIDS PANDEMIC that was first identified in Democratic Republic of the Congo in 1976,HIV/AIDS had truly proven itself as a global pandemic, killing more than 36 million people since 1981.  After the HIV/AIDS another disease started spreading and taking life which was Tuberculosis (TB), TB was an airborne disease that  was easily spread by coughing or s

PWM (Pulse Width Modulation).

Electronic devices are very user-friendly and can be used easily because we can control the device easily and use them according to our needs mostly devices are controlled with the PWM(Pulse Width Modulation) technology. So, in this article, I will tell you about PWM(Pulse Width Modulation). What is Pulse Width Modulation (PWM)? Pulse Width modulation (PWM) is used to control the power that is supplied to various types of electrical devices, most especially to the AC/DC motors. A Pulse Width Modulation (PWM) is a method for generating an analog signal using a digital source. The PWM signal consists of two main components that define its behavior: a duty cycle and a frequency. Duty Cycle. When the signal is high, we call this "on time". To describe the "on time", we use the concept of the duty cycle. The duty cycle is measured in percentage. The percentage duty cycle specifically describes the percentage of time a digital signal is

Snapdragon 855 vs.Apple A12 bionic vs.Kirin 980 vs. Exynos 9820.

We all like flagship level smartphones but why ❓simply because we get all the latest top class features in those smartphones. And the another reason of liking flagship smartphones are their performance because of the use of high efficiency chipsets(processors). So, In this article we will compare the best latest processor from each processor manufacturer i.e. Qualcomm Snapdragon 855, Apple A12 bionic,Huawei High silicone kirin 980 ,Samsung Exynos 9820. Basic Comparison of different processors. SoC(System on a Chip) Configuration. NOTE :- If you don't know what are cores then you can visit my previous article on processor explanation. The Qualcomm’s new Snapdragon 855 is the one Cortex A76 core clocked at 2.84GHz, three more Cortex A76 cores clocked at 2.42GHz and four Cortex A55 cores clocked at 1.8GHz. It is paired with a Adreno 640 GPU. Apple’s A12 configuration is with a 2+4 solution that sees two Vortex cores at 2.5GHz and four Tempest cores at 1.6GHz, it is

VoIP(Voice Over Internet Protocol).

Internet is a very vast network that is used by all the people of the world for doing multiple things. So, if you use the Internet then you know that there are different protocols used for doing different types of work on the internet. So, of those multiple protocols, the one is VoIP (Voice Over Internet Protocol) , in this article, we will know about VoIP protocol, But before knowing about VoIP firstly we will quickly remember Internet protocol (IP). What is IP? The IP (Internet Protocol) is the protocol by which data is sent from one computer to another on the Internet. Each computer (known as a host) on the Internet has at least one IP address that uniquely identifies it from all other computers on the Internet. What is VoIP? The  VoIP (Voice Over Internet Protocol) is a combination of both the hardware and software that enables or facilitate people to use the Internet as the transmission medium for telephone calls by sending voice data in the form of packets using Internet p

CFL(Compact Fluorescent Lamp).

If I ask you a question that what is the main thing by which we can see anything? The answer will be of course light by which we can see the object. For the light source, we use different light-emitting objects like tube lights  and CFL bulbs, and in the present day, we mostly use LED bulbs. So, in this article, we will know about CFL bulbs and how they work. What is a CFL? The CFL is known as Compact Fluorescent Lamp, and traditional Fluorescent lamps and CFLs are very similar. In fact, a CFL is just a compact version of a fluorescent lamp that is smaller and easier to install. The glass tube is bent and both its ends are fixed on a base that holds the ballast and can fit into standard bulb sockets. Therefore, there is no major difference between the principle of a fluorescent lamp and a CFL. CFL converts electrical energy to radiant energy. They are energy efficient and use better technology as compared to conventional Fluorescent lights and bulbs. The CFL has two components.

UAV (Unmanned Aerial Vehicle) The DRONE.

The cinematic shorts are very much famous and that short becomes more impressive when it is taken with a drone. So in this article, we know about the drone, its various components, and its working principle. W hat is a DRONE? The drone is like a flying robot it is also called  UAV  (Unmanned Aerial Vehicle) or a quadcopter because it uses four propellers to fly. The drone is usually controlled with a remote control unit and they can manage all things in the air due to a smart functioning software program. It possesses so many sensors like GPS etc. Components of a Drone. Frame:-    The frame of a Drone works in much the same way as the frame of a car works, that to support and add strength to the vehicle. Frames are typically made from plastic or carbon fiber and can be arranged with different arm variations (tri, quad, hex, oct). Carbon fiber tends to be a favorite because of its strength and lightweight. Motors :- There is a separate motor for each blade/arm. The measure of the RPM
