LiFi Technology - Faster transmission technology in world

LiFi stands for light fidelity. It is a wireless optical networking technology and it uses light emitting diode for data transmission. Its close similar to Wi-Fi, but it uses light instead of radio waves. Which make it so special. LiFi can be up to 100 time faster than WiFi. It uses light to transmit data, which give it advantages of working in areas which is susceptible to electromagnetic interference. The light wave cannot penetrate the walls which translates to much shortage range, and lower hacking potential compare to WiFi.

HOW LI -FI WORKS ?

LiFi works on a Visible Light Communication system. VLCs works by switching the current to LEDs off at very high speed. The technology made LED light bulb emit pulses which is undetectable to human eye and with those limited pulse, data can travel to and from receivers. The receiver than collect data and then interpret them. LiFi can touch the transmission speed at 100Gbps 14 times faster than WiGig, the fastest WiFi in world. Data is captured in modulated light frequency of a solid state LED light source and is then transmitted and received by LiFi enabled devices. A photosensitive detector demodulates the light frequency signal and converts it back in electronic data stream.

The Amazing Vantablack Material...!!

Vantablack is a material developed by Surrey NanoSystems in the United Kingdom and is one of the darkest substances known, absorbing up to 99.96% of visible light (at 663 nm if the light is perpendicular to the material).The name is a compound of the acronym VANTA (vertically aligned carbon nanotube arrays) and the color black. Vantablack is not actually a color pigment or a paint, but a coating of carbon nanotubes. These have the property of absorbing incident light almost completely. Against a deep black background, objects coated in Vantablack material seem to disappear, as the perception of spatial depth is lost. This is because the human eye perceives shapes coated in Vantablack to be two-dimensional. IUPAC Name is Activated carbon high density skeleton. Other names are Multiwalled carbon nanotube (MWCNT), Vantablack S-VIS and Vantablack S-IR. It is insoluble in water. When light strikes Vantablack, instead of bouncing off, it becomes trapped and is continually deflected amo...

NVIDIA Tesla V100 - First Tensor Core GPU

8x NVIDIA Tesla V100 32GB Server As we all know NVIDIA processor are so famous now a days. It give a perfect gaming performance and people used it worldwide. The thing is that it is not only use in personal computer but also at data center, where so many super computer are present for providing services. So, NVIDIA Tesla V100 is a first tensor core GPU. It is especially built to focus on AI, High Performance Computing ( HPC ) and graphics. It is powered by NVIDIA Volta Architecture. It comes with configuration 16 and 32GB and have a performance up to 100 CPUs in single GPU. A single server node with V100 GPUs can replace 60 CPUs nodes. DATA CENTER GPUs Image © NVIDIA NVIDIA V100 for NVLINK Performance with NVIDIA GPU Boost for double precision is 7.8 teraflops and single precision is 15.7 teraflops. Deep learning performance boost is 125 teraflops. Interconnect bandwidth with bidirectional is 300 GB/s. It have memory capacity of 32/16 GB HBM2 with bandwidth 900GB/s. I...

Operating System as Extended machine and Resource manager

Operating system is software that runs in kernel mode even that is not always true. Part of the problem is that operating system perform two essential unrelated function. We can say that operating system is system software that manages computer hardware, software resources, and provide common services for computer program. The Operating System as an Extended machine The architecture of most computers at the machine language level is not developed and difficult to program, especially for input/output. To make this point more concrete, consider modern SATA hard disks used on most computers. Only the insane the programmer would try to mess with hard disks at the hardware level. Therefore disk driver - a piece of software deals with hardware and provide interface to read and write disks blocks. Operating System contain many drivers for control input/output device. Macintosh hardware are complicated. Real processors, memories, disks, and other devices are very complicated and it...
