               Teleportation              What happens if we travel wherever we want with in a seconds ... no matter with distance and time amazing right!! Yes this is possible by teleportation method ... In this article we try to find .. what is teleportation and what are the ways to achieve it... Teleportation is nothing but we can travel from one place to another  place without any medium... In 1878 one English news paper has introduced this teleportation ...but when you observe our ancient history of indian mythology they explained about the teleportation technique. they can use how have  spiritual powers..... Do teleportation possible using our technology ... let's see... Yes this is possible by using quantum teleportation process.. QUANTUM TELEPORTATION We know that everything in the world made up of atoms   Example.. Consider a ball we want to transfer from place A to another place B the...

     Satellite communications                We know that many satellite orbit our planet everyday. and they're helping us in several ways ,you almost surprise to know around 4900 satellite orbiting the earth . The most obvious question that comes to our mind  . why are  these satellite in different orbits How satellite work ??                                    What are the components inside them?? Let's see in detail . We know satellite stay in orbit because of the balance between gravitational pull and centrifugal force when satellite is deployed it is given sufficient speed to balance there two factors .. satellite continue their circular motion without any external energy due to negligible resistance in space so they never lose speed . Which satellite is placed on which orbit it depends on the application and purpose of satellit...

                         Time travel                     We generally make mistakes right. we usually feel for what we did when it  comes to facing that consequences ..what happens if you travel to past and setback that situation crazy right .  similarly every one is curious to see themselves in the future and this  called time travel . In this article we try to find the following ** Is time travel is possible ?? ** If possible what are the ways ?? **What is worm holes ??                         The matter, energy , planets, universe's .are born from the big bang let's assume a river ..the river  started point is big bang ..the water flow is time and earth galaxies are flowing in water and some cyclones are called black holes there is also an ending point to the flow of river.. M...

                   8051 microcontroller                          When we learn anything . we have two doubts why we  are learning and what we are learning . There are millions of applications and appliances that we are using day to day life using microcontrollers Few examples tv, tv remote, air-conditioning, Ac remote, washing machine, refrigerator, keyboard, mouse, DVD drives, USB ports, and so..in your house is full of microcontrollers the list is end less and have massive application's in real world  you not even imagine how many are that's why we are trying to learn microcontroller .. Microcontroller is a small chip which have all the components in it have advantage of microcontrollers is small in size then microprocessor... Let's discuss the parts of the microcontroller  First and most one processor, memory (RAM,ROM), I/O ports , serial ports, ...

         Mobile charger                              We charge our phone 3 to 4 time's a day do yo know what type of charger you have ?fast charging, quick charging , turbo charging, super fast charging ?? And what type of USB cable you have type A,B,C....??while I am searching about this and I am surprised to know some interesting facts about our charger let's deep dive into mobile charger and try to find what type of charger you are using. We know charger have two parts adaptor and sub cable  In first we see different types of sub cables.                  USB ( universal serial Bus) In 1994 "7" company's are manufactured this USB cable the  main aim of the company's is to connect external devices to computer like printer hard-disk scanner  The 1st version is USB 1.0 and then 1.2 the maximum speed is 12mb/s in 20...

  Touchscreen technology                  We use our Phone regularly ..and check frequently for notifications .do you ever asked yourself that how this touchscreen display works??.. In feature every electronic gadgets and home appliance is with touchscreen technology only ... We will try to find how many touchscreen technology's are available...  In 1965-1967 sir reachod EA Gohnson invented first touchscreen system that used for air traffic control... Dr.samuel harst developed first touchscreen sensor... Let's deep dive into touchscreen technology... Ther are 4 type's of touchscreen technology's are there ... 1. Resistive  touchscreen system 2. Capacitive touchscreen system 3. Infraded touchscreen system 4. Surface coustic wave touchscreen system ** 1 resistive touchscreen system..          When it come's to resistive touchscreen system there are two layers one is conductive layer and other one resist...

       DTH( DIRECT TO HOME)                  We love watching Tv right. and spend lot of time on watching favorite films, serials, events programs so on. Present we use mostly DTH. have you ever thought that how DTH working ?? If yes comment below. DTH(direct to home) that means dish which reach our house without any wire's. TERRISTREAL BROADCASTING.. In our childhood days the only channel we have " dhurdharshan " radio signals which transmit to small signal tower and connect to TV with wire and TV converts radio signals into picture   There are few disadvantages . Radio signals cannot transmit to longer distance so people staying in longer distance not able to receive signals.          To overcome this problem the tv studio send signal to satellite then satellite send signals to multiple system operates (MSO) we generally called cable operators. you may observe large antenna's on top of cabl...

                        Mobile communication system                          In olden days the mobile is a luxury  item and used for phone calls only. the data speed is just 2KBPS. But now mobile is necessary to everyone used in everywhere. the data speed is about 2GBPS. Let's see how mobile communication system works. In bottom of your mobile you can see the microphone inside the speaker grill. . while you're talking the voice go's inside the microphone and sent to small antenna which is top of your mobile. antenna converts voice signals into radio waves . when transmitting the signal it act as  transmitter and when receiving the signal same antenna act as receiver so it is called transducer .      Radio waves travel in straight line . while traveling radio waves  if there is an obstacles (buildings) in their path then radio waves d...

         How Internet Works                                 We love steaming on internet right .and we spend lot of time on internet. have you ever wondered that how internet work's?? Let's deep dive into internet. When you are watching a YouTube video Let's understand how internet works by getting to understand details of this data's incredible journey... The data center is thousands of miles away from you and your video is inside it.  The easy way is to sent through satellite's antenna and sent to your  near mobile tower, But it not good idea. Because the distance between the earth surface to satellite is about 22000 thousands miles if the data have to be successful then it travel about 45000 thousands miles it is such long distance then the data delay will definitely happen it is not good for most live streaming application like Amazon Netflix . This way of t...

            8086 MICROPROCESSOR                            Before knowing the 8086 microprocessor first we want to know what is microprocessor...      introduction to microprocessor...                                                Microprocessor use every where in the world . Where there is a program then there is a microprocessor in it .they use in mobile phones, laptops(i3,i5,i7,i7,i9) .  Example:                   When you observe the traffic lights There is a microprocessor to count numbers and  glow lights(red, green yellow).there are lot many more examples . Which use the microprocessors. 8086 microprocessor.  It is intel complete commercial and remarkable ...
