Google CEO Larry Page Developing A Self Driving Air-Taxi In New Zealand

Google co-founder and CEO Larry Page unveiled a Self Driving Air-Taxi  after several days of research. Named Cora, which is an electric aircraft. It runs through the electric charge and driven by drones. Cora can fly 100 km (62 miles) on a single charger. Peoples can operate Cora by "self flying software combined with human oversight".  It will be also available for customer's service, Cora is developed from parent company Kitty Walk in New Zealand. The research will end next 4-5 years and Air-Taxi will run  soon. Kitty walk told in the research time two sits are available for passengers.
The main advantage is it does not need any runway to land and can take off vertically. New Zealand government welcomed this project progression of future technology.

After eight years of experiment this Air-Taxi build up by Kitty Hawk which is a California based company.

See what they told about this-


It rises like a helicopter and lands vertically. Means it doesn't need any runway. Peoples can operate Cora by self-flying software, that's why pilot training is not required. They told that, thay want to available this service at very cheap price.

Another company  Ride-sharing giant Uber is also working on self flying Air-Taxi, on thair own way. Now this company is waiting for approval.

This robot help humans in various operations. They can even do the things that people are unable to do, as such operations are very much risky for humans. This Humanoid Robot is developed and built by NASA.

Why This Robot (Robonaut 2) Has Been Created?

It helps scientists to discover with awesome cleverness. There are certain dangerous and harmful tasks that Astronauts can't do, so Robonaut 2 has been sent to the moon. This robot can work with people hand-in-hand. It helps collect information more easily. They can even go to dangerous toxic environments. At last but not the least, it (R2) is designed so that it can able to vacuum air filters and can walk on.

Some Features And Advantages of Robonaut 2:

They can be developed and built with minimal costs.

• Actually what is VPN

VPN means Virtual Private Network. Far users and branch offices of same organization can securely access associated applications and other network resources through VPN. Because VPN creates a safe connection over respectively less safe network. VPN technology also creates encrypted connection. Single users can send and receive data through VPN secretly to connect proxy servers. They can hide their personal data and can write anonymously.

2 types of VPN:

VPN protocols:

1. Open VPN
2. Internet Protocol Security (IPSec)
3. Secure Socket Tunneling Protocol (SSTL)
4. Layer To Tunneling Protocol (L2TP)
5. Point To Point Tunneling Protocol ( PPTP)

• Unblocking VPNs:

Unblocking VPNs can provide authorization to access those blocked country servers.
Ex- From online shopping site xyz.com gives best offers in US. But you stay in India. By using VPN you can access this online store as a US user.

What are caches memory ?

Cache memory, also called CPU memory. It is the part of random access memory. Cache store some data of any app pr software. When any app loads or any software going to load. CPU searches the loading data at first on cache memory. When it find out on cache it doesn't check on the Random access memory. 

In the case of mobile (RAM in smartphones)

Does cache have any effect on usage of RAM? Can we delete it without getting some issues in functioning of mobile?

 As i told before if CPU don't find out data on cache it reloads the app again and again. It needs time, take more space or storage. And it really effect on RAM. So don't clear cache memory. If this app or data is useful to you.

Introduction:
Engineers at the University of Washington have for the first time developed a method to safely charge a smartphone wirelessly using a laser. Invisible beam from a laser emitter can deliver charge to a smartphone sitting across a room and can potentially charge a smartphone as quickly as a standard USB cable.

What is GSM.

GSM is Global System for Mobile communication or 2G service. It is a digital mobile telecommunication system that is widely used in all over the world. GSM compress and digitize all the data, then send it's down a channel with two other streams of user data which data's has it's own time slot.
GSM uses a variation of time division multiple access (TDMA). Also the most widely used three digital wireless telecommunication technologies TDMA, GSM, and CDMA.

The GSM network architecture consists of different elements like  MSC, AuC,

Mobilities supported in personal communication service.
