Here’s the Reason Why ATM Pin has Only 4 Digit’s

We may come across major things in our day to day life. Most of the times we fail to notice the strange thing in it. ATM machines are not new to us. We are very familiar with the usage of ATM’s. After the invention of ATM machine, the major task of drawing the money from our bank account became so simple. It’s very convenient for us to carry ATM-cum-Debit cards with us. You can withdraw from your account with a simple swipe of you debit card at the ATM’s. ATM machines were installed  all over the world in every street of the cities. There is no wonder that even the extremely remote areas got installed with ATM machines.

Here’s The Interesting Things Behind The Invention Of Automated Teller Machine (ATM):

• The idea of inventing ATM machine came from Computer Loan machine

• John Adrian Shepherd-Barron, a Britisher invented this Automated Teller Machine

• PIN stored on the card was developed by a Britisher named John Adrian Shepherd-Barron.

Now, Here’s a Question for you – Have You ever wondered why ATM pin consists of only 4-digits?

Here’s The Answer:

• John Adrian Shepherd-Barron, the inventor of ATM machine was born to Dorothy Barron (Wimbledon Ladies Double Champion) in Shillong.
• Barron proposed a 6 digit PIN.
• But this idea has to be rejected because of Barron’s wife Caroline.
• This is because Caroline could remember only the largest string of 4-digits.
• 6-digit was too long for her to recall.

But now there are many banks that are offering a 6-digit PIN code for accessing the Debit cards. Sometimes we may even forget the 4-digit code. Just imagine what happens if the PIN was 8 digits like that of passwords for emails, social media accounts etc. So let’s thank that woman.

Ever Wondered Why The Letters On A Computer Keyboard Are NOT In Alphabetical Order?

We are in a digital world now and computers have become our basic need in our lives. And the primary thing we need to operate this machine is a keyboard. Every time I see my keyboard, a question comes into my mind – why are the keys not arranged in the alphabetical order? Why are they MIXED up like this? Is there any reason behind this?

Must Read: how-to-boost-your WiFi Speed

Have you also ever thought of this? If so, here we are going to tell you some facts about the arrangement of letters on Keyboard. Check out why!

The modern keyboard called by the name QWERTY (the name comes from the first 6 letters of the keyboard), has the letters arranged in the same order as that of a TYPEWRITER. Let’s see who made this layout and why didn’t they arrange them in the alphabetical order.

The most popular explanation claims that the key positioning was designed to slow down typists because the early typewriter’s mechanical design resulted in jammed keys and components.

The first keyboard patented by Christopher Latham Sholes in 1868 had the keys alphabetically arranged. The keys were arranged in the serial order because it was the birth of keyboard and the inventor thought arranging the alphabets in a row would be good for the user to type easily and quickly.

But the arrangement of the letters was later changed because of some problems.

Here’s what its layout looked like – The keyboard with arrangements of keys for the second time:

Well, it had its own problems like jamming of keys because of side to side arrangements of letters.

Despite being much faster to learn and easier to use, this semi-alphabetic layout would often jam (note the position of the T, H & S keys) when users typed too quickly. As anyone who’s used a typewriter will tell you, even one single jam or a simple typo, would require unjamming the keys, ripping out the old paper, washing the ink off your fingers, inserting a new sheet, and starting all over again.

Sholes and his partners later sold their design for a typewriter and its keyboard to Remington & Sons, who manufactured the first commercial typewriter. The company again re-arranged the LETTERS and adopted the QWERTY layout as the standard.

The keys of the QWERTY layout are arranged in such a way to make fast typing difficult as old typewriters would easily jam.

There is an interesting fact here. All the letters of the word “TYPEWRITER” could be typed quickly since all the letters were on one row of your keyboard.

This is how the layout of the Keys in the KEYBOARD evolved.

How to Boost Your Wi-Fi Speed by Choosing The Right Channel A Simple Tweak

You no more have to stick with your buffering YouTube videos. Wi-Fi is a sensitive technology, and a simple oversight can negatively impact browsing speeds. There are numerous ways to get a faster wireless network connection at home out of which some are more efficient than others. Here is a tweak that might help you to boost up your Wi-Fi speed.

If you have been browsing the internet in the purpose of finding a solution to help overcome this problem you might have encountered the word channel. First of all, Did you know that your Wi-Fi router has channels? Sometimes, simply by changing the channel on your router can make a drastic difference, especially if you live in an apartment building with lots of interference from other Wi-Fi signals. Even some other gadgets and electronics like cordless phones and microwaves can interfere with Wi-Fi as well.

Here is a detailed tutorial on how to increase your Wi-Fi speed just by choosing the right channel of your router. Check out this simple tweak that help you in the best way to boost up your wi-Fi speed.

Channels in Wi-Fi Router

Most of the modern Wi-Fi home routers broadcast in various frequencies. The Wi-Fi home networks make use of a narrow radio frequency range between 2.4GHz and 5 GHz for signal transmission. Usually, 2.4 GHz is sufficient for large homes with multiple floors since the signal travels distant and obtains the ability to penetrate through walls very easily. But for smaller homes, 5 GHz is the best to go as it offers much faster speeds, although in a shorter range.

Fig: 1

This range has been distributed further into some smaller bands or channels, alike to television channels. There are 14 channels allocated in the 2.4 GHz range separated 5 MHz individual except of a 12 MHz spacing before the channel 14.

This insignificant signal range is the main reason that leads to overlapping of channels. Also, as I have mentioned earlier, there is another fact that different electronic appliances such as microwave ovens, cordless phone, etc. along with the wireless networks of your neighbors may also use the same frequency range that eventually leads to interference with the wireless home network, showing a substantial impact on its performance in an adverse manner.

Reasons Behind Interference of Networks

There are many causes behind the interference of networks with some other wireless home networks. Just have a look at the image given below:

Fig: 2

First of all clearly, observe the above picture (fig: 1) where the channels 1, 6 and 11 are spaced far enough so as not to overlap with each other. These channels are as such the best channels for usage along a Wi-Fi network.

Furthermore, once interference causes amidst your home Wi-Fi networks, it leads to the reduction in the throughput of the system usage. Hence, it is essential to select the proper channel so as to enhance the performance of the WLAN equipment.

Simple Way to Set a New Wi-Fi Channel

Choosing the right Wi-Fi channel is the most important task in cases if your Wi-Fi speed is very slow. Just by choosing the apt channel, it can then boost up the speed of your Wi-Fi network. To change your routers’ Wi-Fi channel, you need to log simply into your router’s web interface in a web browser.

Go to Wi-Fi setting >> Find the Wi-Fi Channel option >> Choose your new Wi-Fi channel.

The next problem that might be rumbling in your mind would be how to pick the right, correct channel for usage. Apart from using the channel 1, 6 and 11, you could further use the following additional techniques to choose the best channel.

How to Make Your Very Own Home Theatre with a 4K TV

Setting up a home theater is a long-lost dream for many movie buffs. They reverie of watching all-time classics sitting with the people of their clan on a comfy couch in a personal environment. However, what keeps them away from taking a step towards setting it up, is the notion that the process is complicated. Believe me; it’s not. Particularly, if you already own one of those 4K Televisions that are ruling the consumer electronics market. So, if you are still spending some good cash on watching movies in the theater every weekend (suppressing your home theater dream), my friend, it’s time to take that much-awaited step to plan your personal home theater.

Choose the Perfect Room

The first step is finalizing the location of the home theater in the house. Don’t worry, even a 10×10 room will be perfect for this project. You will not require taking help from any professional interior designer on this one because all you need to consider is that the room is spacious enough to house all the necessary components. Another aspect to keep in mind is the number of windows in the room. The more the windows, the higher the chances of reflection of light on the TV screen. Alternatively, if you are planning to turn your basement into a home theater, make sure you get all the water lines and electric wires fixed beforehand to avoid leaks and short circuits.

Carpet the Floor

The planned room has vinyl or wood flooring? Carpet the floor to prevent conflict between the sound that comes out from the TV speaker and the floor. Doing this, the sound produced will be clear and pleasant. Carpeting will prevent sound distortion, allowing you to have a great movie watching experience. Also, choose a dark colored carpet to dim the room well and to have a clearer view of the screen when the lights go off.

Paint the Room

If the chosen room has bright walls, get them repainted with a darker shade to make it even with the carpet floor. However, avoid using too dark shades like black, brown and dark grey. They can make the room appear depressing and the people sitting in may feel sleepy and low even when the lights are turned on. Dark shades of purple, red and maroon are the best wall color options for your home theater.

Install Right Lights

To create a home theater that resembles an actual cinema hall, LED Down lights are the right way to go. You can adjust the brightness according to your need and make the room look appealing enough.

Decide the Position of the 4K TV

Another imperative aspect to consider is the placement of the television. If you own a 65 inch 4k TV from any of the luxury brands such as Vu TV, keep the size in mind and get it installed on a wall that is free from windows and shelves. Any distractions on the wall can ruin the movie watching experience for one and all. Also, if you want, get an electric track of motorized curtains installed to keep the TV hidden when no one is using the room. With a click of a button, the curtains would disperse to reveal the TV. Sounds fascinating, right?

In addition, you and your movie buff friends are in for a treat, if you have a 65 inch 4k Vu Premium Smart LED TV that comes loaded with amazing features such as Games Centre, AccuWeather, Opera Web Browser, YouTube access, picture perfect display quality and Netflix ready features. With so many amazing features, the experience of your home theater will just double in no time. Talking about Netflix, the remote of Vu smart TV comes with a Netflix and a YouTube button that makes turning on the apps quick and easy for you to binge watch without any hassle. In addition, you can even connect your smartphone or tablet to the TV for an unparalleled TV watching experience.

Place the Furniture

All the furniture placed in the home theater should face the TV wall in a way that the view is clear for everyone sitting in the room. When creating rows of seating, the furniture placed behind the first and second row should have a higher height than the ones in the front row (just the way it is in cinema halls).

Time to enjoy your favorite flicks again and again from the comfort of your home!
