Token Ring Local Area Network (LAN) Technology is a networking technology for computer networks, it is defined in the specification as IEEE 802.5. It defines the cable types and signaling for the physical layer, packet formats and protocols for the media access control (MAC) or data link layer of the OSI model. It is one of the two forms of implementation of the method.…

Retina Display is the patented name for the LCD which has a higher pixel density so that our eye can not perceive the pixelation at normal viewing distance. Previously we wrote about the basic technical aspects of a typical TFT-LCD Display or Thin Film Transistor Liquid Crystal Display. This article will only describe the specific points about Retina Display.…

4G or Fourth Generation Mobile Telecommunications Technology is not that clear cut like our conventional 3G. LTE is 3.9G, LTE Advanced is taken as a part of 4G. This confusion is the basic reason why we wrote on Long Term Evolution or LTE separately from 4G. 4G is also taken a part of Next Generation Mobile Networks, of which Next Generation Networks is itself a part. Next Generation Mobile Networks (NGMN) is a project of mobile phone companies and mobile equipment vendors to develop the next generation of mobile communication devices. This generation is known as 4G. With the adoption of the standard LTE-Advanced , the project achieved its primary objective. So this is the basic.
4G or Fourth Generation Mobile Telecommunications Technology : Introduction
NGMN is based on previous UMTS infrastructure and therefore a rapid and cost-effective expansion of the existing 3G mobile networks is possible. One of the advantages over the existing networks with High Speed Packet Access (HSPA) is achieving a up to 100 megabits per second, it is much higher speed. The end device used can be permanently connected to the Internet (“always on”).
This will be achieved with a more efficient utilization of the available frequency spectrum, which is also intended to provide for a simpler network architecture and lead to latency of about 10 milliseconds. The network coverage needs not to change. NGMN is based techniques such as WiMAX and Flash-OFDM on OFDM . In contrast to the mentioned method, the frequencies at NGMN however assigned adaptively, so the user at a time distance of up to 0.5 milliseconds can assign each of the network resources required. Thereby a better delay performance is possible than on OFDM systems. Since early 2005, the standardization of NGMN runs through the standardization body.
4G or Fourth Generation Mobile Telecommunications Technology
The “Next Generation Mobile Networks” (NGMN) is a project of mobile equipment manufacturers and mobile operators to develop the next generation of 3G that is 4G. The current standard is the 3G mobile standard, which build on the 2G and the 1G-0G standard. 0G-2G to the standard leads from the root of mobile communications to GSM standard.
UMTS offers the ability to download data under optimal conditions up to 384 kilobits per second. Interference and bug fixes this rate diminishes, but have now thanks to several extensions of the standard ( like HSDPA ) which offers much higher speeds. A high data rate is important for services such as video telephony and mobile internet usage. With the next generation 4G again, significantly higher data rates will be available.

Cloud Computing for High-Performance Computing has been researched and tested by various individual and non-it universities as it is technological outsourcing. Cloud computing and information technology itself, such as change the understanding of IT as a service, is in use for a long term. Organizations relates the cloud computing as the possibility of rapid provisioning of IT processes which are flexible, scalable, on-demand as a service. Many start-ups and established organizations already use the dynamic processing power and storage capacity of the cloud, without having to make large investments. But what is the potential lies in the cloud services for complex, data-intensive calculations for science and research ? Can organizations use the services of commercial cloud providers for high-performance computing ? Particularly in HPC often complex and costly infrastructure are necessary. can we can replace it with a service ?

Cloud Computing and The Consequence of Employment in IT Sector is quite burning topic now as happened few decades back while mass introduction of Computers. With the transformation of business processes and the use of cloud computing solutions, there is a definite change in the requirements for the posts like IT manager. With more penetration of Cloud Computing, some of the individual job descriptions are eliminated altogether. In many industries, Human Resource as a Service, Everything as a Service are being introduced. All these factors making the employees or future employees terrified. Cloud Computing and The Consequence of Employment in IT Sector is a socially important topic, has basically little to do with Cloud Computing as technology itself.
