Well, you must have heard of static and dynamic IP addresses, but what these addresses are, when and why are they required, how are they assigned, I got to know the answers to these questions while teaching a core networking subject. The simple meaning of static is fixed that does not change even if you move to a different network or when you reboot, and the dynamic address is the one that is assigned for a short duration and must be renewed after the lapse of that time or when you reboot your machine.   Static are used when you wish that your system must be always reachable for other machines. Web applications like Web server or File server need to have static IP configured.   So if you plan to host a file server to your home machine, you have to assign it a static IP address so that client machine on your network can map this address to a name i.e. 192.168.1.0 mapped to a name as “ file server” . Another reason is if you want to configure your machine/router for pa...

SDN is short for  s oftware  d efined  n etworking.  Software defined networking (SDN) is an approach to using open protocols  , such as open flow, to apply globally aware software control at the edges of the network to access network switches  and routers that typically would use closed and proprietary firmware. Benefits of Software Defined Networking Software defined networking offers numerous benefits including on-demand provisioning, automated load balancing, streamlined physical infrastructure and the ability to scale network resources in lockstep with application and data needs. As noted on enterprise networking concept , coupled with the ongoing virtualization of servers and storage, SDN ushers in no less than the completely virtualized data center, where end-to-end compute environments will be deployed and decommissioned on a whim. An open flow switch separates these two functions. The data path portion sti...

I do not hesitate to say that if India is to be seen as a powerful and united nation, then the process of urbanization must be accelerated. Romanticization of pastoral ideas, leaving nothing to sadness and pain, is nothing to achieve - 'Ah, our village!' The social-economic, cultural and political arrangements of our villages are deeply paternal, community and caste. On the other hand, the social structures of our cities, at least, clearly and on the surface, are mostly decent and sensitive. India is home to many castes, sub-classes, sects, religions, religions, ideologies and other non-defended social groups. Each of these groups has their own ideas and ways of thinking. With the advent of many foreign customs and cultures, for thousands of years, many contradictions developed between all these different belief systems, which kept the disciples away from each other. These distances contributed to the lack of faith and lack of trust in society resulting from ignorance an...

The use of memory in computing is not new. But while memory is faster than disk by an order of magnitude, it is also an order of magnitude more expensive. That has for the most part left memory relegated to acting as a caching layer, while nearly all of the data is stored on disk. However in recent years, the cost of memory has been falling, making it possible to put far larger datasets in memory for data processing tasks, rather than use it simply as a cache. It’s not just that it is now possible to store larger datasets in memory for rapid analytics; it is also that it is highly desirable. In the era of IoT, data often streams into the data centre or the cloud – the likes of sensor data from anything from a production line to an oilrig. The faster the organization is able to spot anomalies in that data, the better the quality of predictive maintenance. In-memory technologies are helping firms see those anomalies close to, or in, real-time. Certainly much faster than storing data ...

Undertaking an engineering degree is one of the most difficult courses available. As a result, it is also one of the  best paid  professions around. For those who didn’t click the link, 6 out of the top 7 are engineering majors, with petroleum engineers unsurprisingly comfortably at the top of the list. You need to spend a lot of time studying and working hard to be successful in engineering, far more than most degrees. If you want to succeed, consider your final two years to be more or less devoid of a social life. Many students, year after year, make the same mistake over and over again when studying engineering. I have seen countless examples of students who don’t realise they are making this one mistake that sets them up for failure. What is the biggest mistake engineering students make? They don’t manage their time effectively! Key #1 – Develop a realistic and challenging strategy The first key to effectively managing your time is to have a strategy. Wars ...

Jahi McMath is legally dead in California, where a routine tonsillectomy on the thirteen-year-old girl done on Dec. 9, 2013 and she basically bled to death.  But she is still legally alive in New Jersey.  After refusing to let the California hospital harvest her organs, her family insisted that she was still alive and moved her to New Jersey to take advantage of a law that allows them to do so.  New Jersey and New York are the only states which allow families to refuse a diagnosis of brain death if it violates their religious beliefs.  This exception was made to accommodate the beliefs of Orthodox Jews, who believe that breathing indicates life.  Not so long ago, most people and governments would have said the same thing, but then medicine developed the ability to monitor brain function via electroencephalography (EEG machine) as well as more sophisticated technologies such as MRI scans and automatic ventilator machines.  The...

“Scientific evidence for warming of the climate system is unequivocal.” - Intergovernmental Panel on Climate Change Climate change refers to any significant change in the measures of climate including temperature, precipitation or wind lasting for an extended period of time. The term “climate change” is commonly used interchangeably with Global warming and Greenhouse effect . The Earth is surrounded by an envelope of gases comprising of N 2 , O 2 , CO 2 , water vapourand other gases. It is this blanket of gases that controls the temperature on Earth. Climate change is primarily due to the human use of fossil fuels such as oil and coal which emit greenhouse gases like CO 2 , Carbon monoxide in the atmosphere. These gases trap heat in the atmosphere which can have a range of effects on the ecosystem from melting of glaciers to rise in sea- levels, from floods in the low-lying areas to droughts in water deficient areas. While some quantities of these gases are naturally occurring ...
