CompTIA Network+ Certification for Network Administrators. The information technology is ruling the real world quite broadly; these days’ people are using computers, smartphones and other digital devices to perform their professional and personal tasks.

One of the most important and effective aspect of IT is computer networking. Today, internet is the most widely used element of IT, countless people use internet to perform several personal and organizational operations and internet itself is a network of networks. But as compare to that organizational computer network is much more simple but effective, these days most enterprises have established their own computer network which allow their employees to share information and communicate with each other securely. Different enterprises have different network requirements for instance if a company have 200 employees so they have to design network keeping physical infrastructure and number of employees in mind.

High Performance Cloud Computing Networks - [Infographic] Explosive Internet growth, beginning in the mid-late 1990’s, has had a dramatic affect on the evolution of computer networking.

Some new network technologies and initiatives boomed, but faded rapidly into oblivion. Others, notably Ethernet, invented by Bob Metcalfe at Xerox PARC, became the standard and a commodity. While new technologies emerged in the 2000’s to solve many of the performance and latency problems associated with Ethernet, notably Mellanox’s InfiniBand which is rapidly becoming the preferred networking interconnect technology in the Cloud Computing space. InfiniBand offers speeds of 80Gbps between cloud servers and between cloud servers and cloud storage. This extreme performance is driving big data implementations and cloud deployments that rival the performance of High Performance Computing environments.

It's a great primer for students and a nice refresher for others. IP subnetting is a fundamental subject that's critical for any IP network engineer to understand, yet students have traditionally had a difficult time grasping it. Over the years, I've watched students needlessly struggle through school and in practice when dealing with subnetting because it was never explained to them in an easy-to-understand way. I've helped countless individuals learn what subnetting is all about using my own graphical approach and calculator shortcuts, and I've put all that experience into this article.
