How DTH work's??

       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 cable operators home from cable operators home connects all the homes using wires ..
We have many disadvantages.
As dish wire length increases then  strength of the signal decreases so we face low picture and sound quality sometimes we see grains on screen. cable operators put amplifier for every 300 meters  also we face problems in quality. we pay money for unwanted channels.
In 2003 dish tv has introduced this technology in India .in space there are lot of satellite either India or foreign. every satellite have transponders this transponders receive the signals and send direct to antenna which is top of your home every transponders receive 5 to 10 channel's. satellite are in space about 36000 kilometers away.in geostationary orbit it means the satellite rotate to match the speed of the earth this because satellite remain in same position to transmit signals.
There are 6 DTH Operators sun direct, dish tv, airtel, big tv, free dish
Antenna is in curved shape because every signal that incident on antenna that reach same point. different satellite have different direction so antenna is in different positions.
This feature technology which is very useful because we use optical fiber cables to every home instead of using satellites so cost may reduce and also we use internet to.

I hope you learn something new. thank you

Brain-Computer Interfaces (BCIS).

   Brain-Computer Interfaces (BCIS). This is the example and possibility article which  BCIS will create the impact in below sectors.  1. Seamless Integration with AI:     Humans are connecting their minds to artificial general intelligences through advanced brain-computer interfaces. These interfaces enable real-time communication between the human brain and AI, granting access to vast amounts of information, problem-solving capabilities, and creative resources. This integration is revolutionizing fields like scientific research, software development, entrepreneurship, and art. Enhanced individuals can achieve perfect scores on IQ tests, viewing the world mathematically, deriving measurements, creating new datasets, and utilizing probability distributions to predict events. 2. Enhanced Access to Information:  B rain-computer interfaces provide constant access to petabytes of information, increasing memory exponentially. Users can summarize data fr...

What happen when oxygen disappears for 5 seconds??

                                 Oxygen                                         imagine if all the oxygen was disappeared not forever just for 5 seconds, what will to the atmosphere, what would happen to the environment. take a deep breath the more you taking is 21% of oxygen in our atmosphere 78% being nitrogen, although it's not the most abundant gas in our atmosphere. It is the most important. Without oxygen, plants, animals, water and us humans wouldn't be where we are today. 5 seconds may not sound like a whole lot of time to be without oxygen. Most of us can go at least 30 seconds without taking a breath. So it would happen too fast for your body to even notice your breathing would actually remain normal.                          ...
