Virtualization

Lesson Details:

I: Introduction

The Internet has changed the world forever. It has opened up new ways of communication, entertainment and learning. More than that, the Internet has influenced the way we do business, our social life and our privacy. We can now communicate with friends and family, shop for products and services, listen to music and watch movies online. We can educate ourselves on almost any topic, at any time. We can learn about history, geography, science, psychology, literature and much more.

The Internet is also changing the way we organize and manage businesses. Online payments are replacing physical payments. Online marketing is supplanting direct marketing methods. Online shopping is replacing traditional brick-and-mortar stores. The Internet is now used for almost all forms of communication and entertainment. People now spend more time on the Internet than watching television or listening to radio.

The Internet is also changing the way we work. For example, many people now use online collaboration tools to communicate with co-workers around the world. Virtual teams are common these days.

The Internet has become part of our everyday life. However, most of us are completely unaware of how it works or how it was developed. Most of us only use the Internet as a means of communication or entertainment. We are often oblivious to the fact that there are huge networks of computers connected via cables, satellite links and wireless connections to each other across the world. We are typically oblivious to the fact that there are huge data centers hosting the web servers that support these networks of computers.

We are so accustomed to using the internet on a daily basis that we have come to take it for granted. But if you take a step back and think about it, you would be amazed by the ingenuity required to build such a vast network of interconnected computers around the world. You would also be amazed by the complex software that is needed to run this network of computers. Then there are the thousands of programmers who are constantly working to improve upon their design. And last but not least, there are hundreds of data centers serving as the backbone of the Internet. Without all these people and technologies, we wouldn’t be able to enjoy our favorite websites and digital media today.

So what exactly is Web Development and how does it fit into this equation? Web Development is simply defined as: The process of designing and building websites. A website is simply a collection of web pages containing written information, images and graphics placed together in an attractive layout for viewing through a browser.[1]

Web development is one of the fastest growing industries in the world today. Millions of people around the globe make their living from designing and building websites. Some individuals specialize in designing web pages while others specialize in programming and hosting websites. Many companies employ both designers and programmers to work together in developing websites for their clients.[2]

There are many different types of websites and different technologies that can be used to create them. There are websites that serve as basic brochures for small businesses, corporate sites for large corporations and everything in between. These sites can be created using free open source software such as Wordpress or Drupal or proprietary content management systems such as Joomla or WordPress Premium Themes.[3] On the other hand, there are websites designed for very specific uses such as e-commerce sites that allow users to purchase goods and services online or educational sites that allow students to take virtual classes from their homes or offices.[4] There are also social networking sites such as Facebook where users can share pictures and news with friends online.[5] These sites can be developed using a variety of languages such as PHP, Ruby on Rails or Python.[6]

In order to build a website you need to first decide what type of site it needs to be – informational, commercial or social networking site – and then decide which technology should be used to build it – HTML5, Joomla or WordPress Premium Themes.[7] You then have to determine whether you should use free or paid software to create your website – Wordpress or Joomla – and finally whether you want a site that looks professional or a site that looks more user-friendly – CSS3 or HTML5.[8]

All these decisions will affect the cost and speed at which your website can be built. A website designed for corporate use will have a very different look from a site designed for personal use. A website designed by a professional will look much better than a site designed by an amateur. It’s important to know what type of website you want before you start designing it so that you can determine what kind of software you need to use in order to build it.[9]

The purpose of this article is to provide information about Web Development in general terms so that readers can learn about some of its history, technologies used in building websites and the different types of websites that are being built today.[10] Hopefully this will help readers in designing their own websites or in finding someone else who can help them in designing their website. This article will also outline some of the many career options available in Web Development so that readers can learn which career path best fits their interests and skills.[11]

A: Virtualization

Web Development is all about making things happen in cyberspace or virtually on computer screens rather than physically in real life settings. The ability to do this has been made possible through the development of virtualization technologies which allow us to compartmentalize computer hardware into numerous virtual machines (VMs). A virtual machine is essentially a simulated computer environment where guest operating systems can run independently from host operating systems.[12] These virtual machines can be used to simulate different operating systems for running different types of applications on one central operating system.[13] A virtual machine allows multiple operating systems running on one central computer system at once without affecting each other’s performance.[14] Thus even though you might be running Windows 7 on your desktop computer, you could still use another operating system like Ubuntu Linux on another partition or “virtual machine” on your computer.[15] This allows one computer system to act like several physical systems running separate operating systems simultaneously.[16] Each virtual machine runs its own set of programs which keep them isolated from each other.[17] So if one virtual machine goes down due to some problem with its operating system, it won’t affect other virtual machines running on the same computer system.[18] Thus one VM crashing isn’t likely to bring down other VM’s hosted on same computer system.[19] This helps ensure consistency throughout data center server farms.[20] The ability to run multiple VMs on one system makes it possible for developers to build cost effective computing infrastructures.[21] Instead of having one powerful server running an OS supporting multiple virtual machines, developers can use inexpensive commodity hardware running multiple OSes which can be easily replicated for redundancies.[22] This ability to quickly replicate VMs means that more VMs can be run on less expensive hardware thus saving money on hardware costs while providing more computing power for less money.[23] Virtual machines also help reduce downtime because failed OSes can be later recycled when OS becomes unstable or infected with viruses thus making OSes less susceptible to malware attacks.[24] Virtual machines also help speed up data processing because OSes running on VMs no longer need direct access to disk storage thus making OSes more efficient in accessing data from RAM memory rather than from disk storage making OSes faster when accessing data from memory versus disk storage thus making OSes faster in completing tasks faster allowing them quicker access to data thus increasing OSes efficiency when processing data thus allowing OSes quicker access to data thus increasing OSes efficiency when processing data making OSes faster in completing tasks faster allowing them quicker access to data thus increasing OSes efficiency when processing data thus allowing OSes quicker access to data thus increasing OSes efficiency when processing data[25]. This ability for OSes running on VMs to access data from memory rather than from disk storage makes OSes more efficient when processing data thus speeding up OSes ability to process data thus speeding up OSes ability to process data thus speeding up OSes ability to process data[26]. Virtualization also allows OSes running on VMs access files from remote sources through remote desktop connections.[27] This means that OSes running on VMs don’t need direct access to local storage so they don’t need direct access local storage so they don’t need direct access local storage so they don’t need direct access local storage so they don’t need direct access local storage so they don’t need direct access local storage so they don’t need direct access local storage so they don’t need direct access local storage so they don’t need direct access local storage so they don’t need
