telephones bell to sell. When you want to make a call, what do you do? Teach out for a cell phone a use line line pluck to of all, perhaps the one in the post office or the phone at the grocery store, where you pay the shopkeeper to use it. Whichever it is navy, you make the call remains the same. You entered the number and wait for it during, but it wasn't always the symbol. An egg. Zander Graham Bell invented the telephone in 18 eighties. He made the first call on March, then 18 76 in his office and Boston USA to his assistant, Thomas Watson, well shouted into the mouthpiece, asking Watson to come and see him. The assistant heard Bell through his ear piece and came running from the next room. At that time, the telephones did not have dials the two phones, who are directly connected to each other by a wire. As more people began to get telephones, a central place Colin Exchange, was set up. The exchange had a switchboard connected to every telephone in the area, and operator could plug in the fires on a switchboard to connect any two phones. A switchboard look like this, and the telephone's looked like this. They had a separate mouthpiece to speak into and an airbase to listen from. They still didn't have number dials. How did you make calls them? Hello? How may I help you? Operator, Could you please connect me to the doctor? Andrew One moment First you picked up the receiver. A telephone operator could great you. The operator would then plug in a few wires and doctors phone would start ringing. But you had to be mount ful of what you said, because the telephone operator could listen to your conversation if she wanted to. As the number of telephones grew, it was not possible for an operator to know all the connexions, so telephones were designed to have dials. You dialled a number. Instead of telling the operator to connect you, this number would get transmitted to a switchboard that could automatically connect telephones. However, operators still routed long distance scores. In the late 19 twenties, the design of the phone changed change. The mouthpiece and the air peace were fused into a single handset. You could hold the handset in one hand, our crackle it in between your neck and shoulder, leaving your hands free to write or weird war watts. Soon, people wanted to make calls on the move. No, they didn't have cell phones yet, but you could stop on the street and called someone from public telephone booths. By the 19 thirties, many major cities across the world had such boots. In fact, this is how most people made calls. Only very rich people had telephones at home some years later. People wanted to use telephones while driving, so phones complete with handsets and dials were been built into cars. But these car phones had no wires. They used radio waves to connect to other phones. In the 19 seventies, a few people had phones that they could carry around in their bags. This was the satellite phone. It could connect to other phones using satellites. SAT phones were never popular because they needed a clear line of sight to a satellite in the sky. So if we lived on the second floor of a 20 storey building, he would have to go up to the terrorists to make or receive calls. Cellphones began to be used at around the same time. These did not need a straight connect with a satellite they connected to a tar nearby so you could make calls sitting inside your house or office. The first cell phone, made in 1973 weighed more than one kilogramme. Later, it got smaller and smaller until it could fit into your pocket. A cellphone is convenient in other ways, too. Landline phones have to be connected with wires. This means a lot of digging to lake cables across and between downs, since this also requires money. Many villages did not have phones, but the violence cell phone has changed that nearly everyone has a cell phone Now. Today, cell phones are for more than just making calls. You can chat, play games, son. The emails, browse the Internet, listened to music, watch movies, click photos and record videos. Now, lot abs. What we call a smartphone is really a computer that can also make calls. What else could a phone of the future do? Today you can speak out your friend's name and your phone will call her up. Maybe one day you would be able to tell your phone, find me the number of my third standard math teacher, and it would. The phone might be able to beam out three dimensional images of objects so you can look at a school back from every side before you buy it online on the inside, too. I also imagine these phones as bendy. You can wrap them around your wrist or roll them up to fit a tiny purse and charging there has to be a better way to do that. Solar cells would be great. You would only have to be out in the sun to charge it or motion based charging. This produced candidate energy, which means that the phone would keep getting charged as longer. It was on the move. If the battery was dying, you could take a quick run down the road. The phone would get charged and you would get some exercise. Smartphones become outdoor date very quickly. Most people threw away their phones in one or two years to buy New Year ones. That means a lot of waste. How nice it would be. A phones were earth friendly, no harmful radiation, no toxic materials or reusable or biodegradable parts. Now that's really smart technology. Now tell me, what do we think phones will be like in the future. In Vendor and teacher Alexander Graham Bell invented the telephone. Other scientists also worked on similar inventions. Bell's parents inspired him to learn about sound and speech. His father was a profession of elocution. Alexander's mother was almost completely deaf, but she learned to pay the piano. Alexander used to speak close to her forehead so that she could feel the vibrations and make out the words. He later started a school for the deaf in Boston. Throughout his life, Alexander kept discovering new ways to communicate. He had 18 patents to his name. His first invention as a 16 year old was a machine to remove husk from wheat grains. Bell was fascinated by the way sound travels through five rations. If you place your fingers on your throat and speak, you can feel the vibrations of your vocal chords that make the sound. When somebody speaks the vibrations, reach your ears and make the ear drum vibrate. That's how you hear things. As people move father away, the vibrations become vicar and fade out
