All About Cellphones
Cellphones are the most revolutionary discovery of technology made so far. This thing was invented just to call anyone away from you. But now if we see cellphone can do anything we want them to. You can use a search engine, you can calculate sums or you can even play games on it.
When this thing was invented the first phone weighed more than 2kilograms which was used to call in 1973. After that first cellular phone came to market in 1979. Now if we compare today’s cell phone to 50 years back cellphone, we will see a lot more difference. Today’s phone is just a sleek design handset that you can carry in your pocket, while 50 years ago people used to carry it in a car because they were too heavy and big in size.
The basic work of a cellphone is that it works like a 2-way radio that we use to talk to a person. We can use this thing if the person is seven seas away from us. Cellphone sends electromagnetic microwaves from one base station to another base station. They are sent through antennas. This is called a wireless connection. When the first digital connection came it was known as 2G (second generation). And now in today’s world, we use the 5G (5th generation) of digital connection, and research is going on 6G (6th generation).
If we talk about the shapes of cellphones so the phones that came earlier were heavy and bulky. And the phones that we use right now in today’s world is just smart, sleek design that looks very catchy. The one that came earlier was having buttons in them so you have to write every word by finding it on buttons while now we have touch screens which are easy to use and we can easily write anything we want.
If we talk about the modernity of cellphone so like a few years ago, we didn’t have trust our own cellphone as they can be hacked anytime but now people this much believe on their phones that they even have their bank accounts opened in that even they can directly pay from their phone without using any kind of plastic payment method from the bank.
We can even play games on cellphones, not just ordinary games even those games that we used to play on a proper computer desktop. A few months ago, a gaming company also worked on cloud gaming. Cloud gaming means that those powerful games that we can’t play on cellphones or our cellphones can’t handle it so we can just use a cloud gaming app that will start a game on a server and stream it on our cellphone which we can play it. This thing is still under process. The one we have still have some bugs and issues but still, something is better than nothing.
The two mobile operating systems that now smartphones use are Android and IOS. Android is the one that is used for touchscreen mobile devices which are sponsored by Google. This operating system came to market in 2007 with the first commercially available Android device. The latest android that we use now is android 11 which was released on September 8, 2020. The competitor for Android is IOS which is the operating system exclusively for those mobile handsets that are manufactured by Apple these phones are known as iPhones. Which was initially released on June 29, 2007. And the latest one is known as 14.6 released on May 21, 2021.
