What's the Fastest Possible Internet Speed?

Hello my friends, Welcome to Aky's Technoworld, the coolest texture on the web.

We have gotten use to most everything having some kind of a speed limit. The roads we drive on, the airplanes we fly and even the photons of light hitting your eyeballs right now.

But what about the internet? In just two decades we've gone from 28 k connections to speeds of 100 megabits per second being the norm. With demand for even faster performance and more connectivity thanks to a streaming video digital game distribution and internet enabled smart gadgets.




The question becomes where exactly the roof on this thing is? Well let's start by having a look at the fastest current internet speeds. I'm not talking about the handful of people in like estonia or north carolina who have 10 gigabit connections at home.


Now we think much bigger than that. The internet backbone, that forms the main highways for the world's data. Although there are plenty of routes that boast speeds of 100 gigabits per second or even higher that is actually child's play compared to the most advanced infrastructure in the system.




As of the time i write this post the fastest portion of the internet backbone is an undersea cable called moriah stretching from virginia beach to bilbao. It can transfer data at an astonishing 160 terabytes per second. I mean that is about like every single person in portugal deciding to stream a 4k video at the same time. And get this the cable isn't much wider than your average garden house.




So how exactly does it move data so quickly? Well as we know, its only possible through optical fiber. But, big undersea cables like moriah use optical amplifiers at specific intervals to keep the signal strong as it flows down the pipe. 

So just like an unamplified light from a cheap laser pointer won't go on forever and hit the moon, light can get attenuated inside an optical fiber as the materials inside do not reflect light perfectly scattering and absorbing it to some degree. So, by using amplifiers combined with using several fibers in one cable and multiple wavelengths per fiber to represent different data streams, these undersea cables can be tasked with carrying huge amounts of information.

So back to our original question though, can we go even faster? Well as technology improves and we deploy materials that can reflect light more effectively and find more efficient ways of using the light spectrum maybe by cramming more wavelengths into a single fiber, we could actually see speeds of over a 1 PB per second (1 PB=1000 TB) and even higher on just one fiber. And then you could actually multiply even that by several times by putting several fibers into one cable. As long as the rest of the infrastructure can handle processing and separating all of the different signals passing through it.




Keep in mind that most modern optical networks use infrared light which is relatively low frequency and therefore it can't carry as much information as more energetic high-frequency forms of radiation. 

So, in the future we may even see information carried via UV light. If we can find an effective way to transmit it using materials that can stand up to its higher energies and keep it from being attenuated too much.

Though we probably wouldn't want to use it to replace wi-fi, unless we all want a bunch of skin cancer. So, the answer then well you can always build a fatter pipe or use higher frequencies to go faster. Meaning that in theory there isn't really an upper limit that we can identify quite yet. But of course, in the real-world concerns about cost, practicality, signal strength, energy consumption and safety will provide concrete challenges. And do remember of course that your home internet connection will always be several orders of slower than whatever Microsoft is installing on the ocean floor.

Vivo to Be First Smartphone Maker With Synaptics' In-Display Fingerprint Sensor

Hello my friends, Welcome to Aky’s Technoworld, the coolest texture on the web.

In world of Technology we have many new technology updates in smartphones. All mobile companies try to give us latest technology in smartphone.


Few day ago Synaptics announced a new technology 'In Display Fingerprint Sensor'. Synaptics announced that this technology will working with top 5 smartphone manufacturer. However synaptics didn't reveal which of the top 5 manufacturers will bring first "In Display Fingerprint Sensor". Samsung was first company that announced about this technology and also bring it in future.





Today, Patrick Moorhead, who is an independent tech industry analyst and founder of Moor Insights & Strategy, took to Twitter to announce that he tested a Vivo smartphone with the Synaptics in-display fingerprint reader. In one of his tweets he wrote,
"Synaptics figured out what no other hardware technology company could, which was to mass produce a secure, under-display fingerprint reader. We’ll see these first in Vivo smartphones, hope to see this tech on Samsung, Apple, Moto, LG, others.”





He further told that fingerprint sensor was accurate and faster than expected. The technology implemented by Synaptics uses a CMOS sensor which is about 0.7 mm thick and is able to read the fingerprint from under the display without a problem.

According to synaptics, this sensor is twice faster than the Apple's FaceID software. They also said that, everyone knows that FaceID is slow and the real challenge that Synaptics faces are Fingerprint sensors on phones like the Google Pixel 2 or the OnePlus 5T.





Still, its a very big achievement for the tech-industry as manufacturers will finally be able to make a truly bezel-less phone with no compromises. Earlier this year Vivo also showcased a prototype smartphone with an in-display fingerprint sensor developed by Qualcomm, but that project failed to take off. However, in collaboration with Synaptics, Vivo has successfully produced a fully functional prototype and the dream of a smartphone with an in-display fingerprint sensor is about to become a reality.

SSD (Solid State Drive) vs HDD (Hard disk drive) as Fast As Possible

Hello my friends, Welcome to Aky’s Technoworld, the coolest texture on the web.

Which is better an SSD or a hard drive? Honestly it's sort of like asking which is better a motorcycle or a semi-truck? Alright so you might be sitting there going that's a weird thing to say Aky, why would you say something like that? And my answer is because they're really not that comparable, they're just different.


Let's start with performance when it comes to raw speed SSDs are faster. I see many folks comparing the sequential speed of an SSD to the sequential speed of a hard drive and say, “oh well they're kind of similar”. But the reality of it is unless you copy large files back and forth all day this specification is pretty much meaningless. I'm serious, it has nothing to do with the way that they will do that you will perceive the performance in the real-world.





SSDs are all about little data transactions that happen all the time all over the place when you're running something like an operating system on them or You know an instant message comes through or a program launches and many other process, it needs to access a ton of little files all over the place. These are the times when not having to physically move ahead across a disk allows an SSD to utterly destroy a hard drive in terms of performance. In system responsiveness any modern SSD will be easily several times faster than any hard drive and sometimes much more than that.


Ok that's great but, what if you have lots of data to store and that's your main concern. It's not like playing back video or music files or looking at your archive of pictures requires blazing fast performance. So this is where hard drives still excel at the time of filming these 160 dollars buys you either a 256 GB SSD or a 4 TB. Yes, a 16 times larger hard drive. For that kind of difference in price per GB, you could literally build two hard drive based storage boxes and have one of them set up as an off-site backup with the money that you saved by not using an SSD based backup solution. So, yes folks for mass storage of data we are a long way away from hard drives being replaced by SSDs.


Okay but what about reliability? Now this one's a little bit complicated. Hard drives are pretty reliable these days. But as devices with moving parts they will die eventually. The good news is they usually give warning signs like, if your hard drive is making clicking noises right now. But the bad news is that any kind of use will wear them out. For SSDs reading from them a lot won't really wear them out very much especially if you keep them running cool. But, if you write to them heavily you can kill a consumer-grade model relatively quickly. 




So I guess I'd put it this way. In an environment where shock is an everyday occurrence such as in a notebook or tablet I would choose SSD every time. In an environment where that's not the case, then reliability to me is a secondary factor after I determine my performance and storage needs. It leads us to the in-between solution hybrid drives. These leverage the technology of hard drives and SSDs at the same time.

USB 3.0: Here's everything you need to know

Hello my friends, Welcome to Aky’s Technoworld, the coolest texture on the web.

Today we're going to tell you everything you need to know about USB 3.0. The main advantage of USB 3.0 is speed. It is up to 10 times faster than the last generation USB 2.0. While it's only half as fast as some other technologies such as USB-C and Thunderbolt, it is universally compatible it's right in the name. So it's backwards compatible with USB 2.0 and you don't need a special computer to take advantage of it.









If you're not sure if your device supports USB 3.0 you can check the manufacturer specifications or another easy way to tell is check the inside of the connector the key that keeps you from putting it in the wrong way is usually blue on USB 3.0 devices. Now most USB 3.0 devices these days are storage devices because that's where you can take advantage of that extra performance. However, there are other devices that are available such as things like external video capture devices that USB 2.0 is not fast enough for but USB 3.0 is.





I often get asked where to plug a USB device into? The simple answer is because of that backwards compatibility it doesn't matter. All you do is, plug the USB Drive into the USB port which is usually easy to recognize because it has a blue colour coded key on it. If that's not present you can look inside the connector to see if there's additional pins.

Your computer will also usually prompt you if you install a USB 3.0 device into a USB 2.0 port saying, “hey you've got USB 3.0 ports if you want to take advantage of that extra speed switch it over to that.”

Facebook's new "Did You Know" feature asks you to answer icebreaker questions

Hello my friends, Welcome to Aky’s Technoworld, the coolest texture on the web.

Facebook never miss a chance to amaze us. Facebook always comes with amazing new features. Now Facebook has added new features called “Did You Know”. Facebook has started to include some personality related question that prompt on user’s profile, as spotted. This questions are tacky in nature and it placed at Lower left of your Desktop profile as “Did You Know” or above your recent status on mobile as “Fun Facts”.



Posited as a way to share an icebreaker about yourself, there’s the ability to cycle through several different prompts of different questions until you land on one you’d like to answer. If you choose to answer of any question, it will be posted as a text status with a coloured background, under new category “Answer a Question.”





Most of the question that are asked are straightforward and some other questions are simply weird. Here are some questions of the prompts that I was given

  • If I could choose to be an amazing painter or a brilliant mathematician, I’d rather be...
  • The best thing about the internet is...
  • If I could bring anyone back to life, I would bring back...
  • The best dance move of all time is...
  • If I had to be locked for a week in a room that was completely dark or completely bright I’d rather...

As I notes, these types of questions feel evocative of tbh, an iOS app that Facebook recently acquired. The app, which has been already launched in August, allows you to send prewritten compliments to friends based off of prompts like “who has the best smile?” A statement Said by Facebook to The Verge that, “it was interested in the way tbh was building community using polling and messaging, an intersection Facebook itself has recently been delving into very literally with Polls.”
