Media

Mass media refers collectively to all media technologies, including the Internet, television, newspapers, and radio, which are used for mass communications, and to the organizations which control these technologies.

Mass media play a significant role in shaping public perceptions on a variety of important issues, both through the information that is dispensed through them, and through the interpretations they place upon this information.They also play a large role in shaping modern culture, by selecting and portraying a particular set of beliefs, values, and traditions (an entire way of life), as reality. That is, by portraying a certain interpretation of reality, they shape reality to be more in line with that interpretation

Internet

The Internet is a global system of interconnected computer networks that use the standard internet protocol suites (TCP/IP) to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents of the World Wide Web (WWW) and the infrastructure to support electronic mail.

Most traditional communications media including telephone, music, film, and television are reshaped or redefined by the Internet, giving birth to new services such as Voice over Internet Protocol (VoIP) and IPTV. Newspaper, book and other print publishing are adapting to Web site technology, or are reshaped into blogging and web feeds. The Internet has enabled or accelerated new forms of human interactions through instant messaging, Internet forums, and social networking. Online shopping has boomed both for major retail outlets and small artisans and traders. Business-to-business and financial services on the Internet affect supply chains across entire industries.

Communication

E-mail is an important communications service available on the Internet. The concept of sending electronic text messages between parties in a way analogous to mailing letters or memos predates the creation of the Internet. Today it can be important to distinguish between internet and internal e-mail systems. Internet e-mail may travel and be stored unencrypted on many other networks and machines out of both the sender's and the recipient's control

Data transfer

File sharing is an example of transferring large amounts of data across the Internet. A computer file can be e-mailed to customers, colleagues and friends as an attachment. It can be uploaded to a website or FTP server for easy download by others. It can be put into a "shared location" or onto a file server for instant use by colleagues.

Information

Many people use the terms Internet and World Wide Web, or just the Web, interchangeably, but the two terms are not synonymous. The World Wide Web is a global set of documents, images and other resources, logically interrelated by hyperlinks and referenced with Uniform Resource Identifiers (URIs). URIs allow providers to symbolically identify services and clients to locate and address web servers, file servers, and other databases that store documents and provide resources and access them using the Hypertext Transfer Protocol (HTTP), the primary carrier protocol of the Web.

The Internet has enabled entirely new forms of social interaction, activities, and organizing, thanks to its basic features such as widespread usability and access. Social networking websites such as Facebook, Twitter and MySpace have created new ways to socialize and interact. Users of these sites are able to add a wide variety of information to pages, to pursue common interests, and to connect with others. It is also possible to find existing acquaintances, to allow communication among existing groups of people.

Communications

Communication is a process whereby meaning is defined and shared between living organisms. Communication requires a sender, a message, and an intended recipient, although the receiver need not be present or aware of the sender's intent to communicate at the time of communication; thus communication can occur across vast distances in time and space. Communication requires that the communicating parties share an area of communicative commonality

Today we have the choice of voice, video, text, instant message, social networks, gaming networks, Skype, Google Voice, voice enabled Twitter and Facebook etc. These choices and the advances in mobile communication devices are responsible for this communication paradigm shift. The ability to take all this communication with you has changed us as much, or more, than the communication applications themselves. The way we treat or interact with one another socially has forever changed.

The Internet has revolutionized the way we communicate. E-mail has been the most rapidly adopted form of communication ever known. Less than two decades ago, not many people had heard of it. Now, many of us e-mail instead of writing letters or even calling people on the phone. People around the world send out billions of e-mail messages every day. Texting, email, and social network communications appear to be taking priority over communicating with those in our presence

Transportation

Transport or transportation is the movement of people and goods from one location to another.Modes of transportation include air, rail, roads, water, cables, pipelines, and space.

Today, automotive technology is on the verge of a giant leap forward that could be as revolutionary as when the carriage gave up the horse at the beginning of the 20^th century. And it will not only involve new power systems, but it will probably include new vehicle types - personal vehicles that we’ve only barely envisioned at this point - and perhaps even a restructuring of cities and the way we do business.

Transportation helps shape an area’s economic health and quality of life. Not only does the transportation system provide for the mobility of people and goods, it also influences patterns of growth and economic activity through accessibility to land. Furthermore, the performance of the system affects such public policy concerns as air quality, environmental resource consumption, social equity, smart growth, economic development, safety, and security.

Improvements in transportation has now decrease the time taken to travel from one place to another.
Now, commercial aircrafts, large ocean-going vessels, and containerisation greatly increased the movement of goods and people from one place to another.
Containerisation has reduced the time and cost of moving goods over long distances. It has also simplified the transfer of goods from one mode of transportation to another since it can be easily transferred from ships to trucks.
Efficient and integrated transportation infrastructure e.g. airports,railways and highways helped facilitiate the mobility of goods and people around the world.

Globalization

As humankind moves into the 21st century, current world issues will continue to develop and expand their impact on the world. From global warming to the AIDS epidemic, new global concerns arise every day. In an attempt to make sense of these serious and complex issues, we have coined the terms "globalization" and "sustainability".

Globalization is defined as the trend towards greater interconnectedness of the world's social and economic systems; it is essentially the formation of a "global village". Sustainability, however, looks at whether an area has reached a level of development that meets the needs of its existing people without jeopardizing the ability of future generations to sustain themselves. These two terms are intertwined in that we must control our rate of globalization, in order to achieve sustainable development. If we do not acknowledge that a balance between globalization and sustainability is necessary, there is little hope for the future.

Globalization has become one of the principal symbols of economic, cultural and political life in the 21st century. Although there is no precise definition of globalization, due to the complexity of the term and the varying attitudes towards it, put simply it is the process by which nationality is becoming all the time more irrelevant. International organizations such as Coca Cola, Disney, McDonald's, sony, shell oil and IBM, symbolizes such a process and progress of globalization.

The benefits of globalization are obvious: faster growth, higher standards of living, and new opportunities. However, globalization's benefits are very unequally distributed; the global market is not yet underpinned by shared social objectives, and if all of today's poor follow the same path that brought the rich to prosperity, the earth's resources will soon be exhausted. The challenge we face is to ensure that globalization becomes a positive force for all people instead of leaving billions in squalor.

If we are to get the most out of globalization, we must learn how to provide better governance at the local, national, and international levels. We must think afresh about how we manage our joint activities and our shared interests, since so many challenges that we confront today are beyond the reach of any state acting on its own.

3D: Viewing in the 21st century

3Dimensional Refers to objects that are rendered visually on paper, film or on screen in three planes (X, Y and Z). It is a system or effect that adds a three-dimensional appearance to visual images, as in films, slides, or drawings.

it allows items that appeared flat to the human eye to be display in a form that allows for various dimension to be represented. These dimensions include width, depth, and height.

3-D image creation can be viewed as a three-phase process of: tessellation ,geometry , and rending . In the first phase, models are created of individual objects using linked points that are made into a number of individual polygons (tiles). In the next stage, the polygons are transformed in various ways and lighting effects are applied. In the third stage, the transformed images are rendered into objects with very fine detail.





Much of the development around the technology is concerned with bringing 3D to your living room, such as is the case with the 3D-enabled TVs from LG and Toshiba, for example, samsung's 3D LED monitors, or the addition of3D movies to the streaming service VUDU, which can pipe Hollywood entertainment directly into your living room. But 3D is showing up on other screens, too - mobile phones and tablets ,gaming device and mobile 3D DTV device

Apparently, viewing 3D images, even the glasses-free kind, can negatively impact the vision development in small children. According to a report from The Wall St. Journal, both Nintendo and Toshiba have recently issued warnings about the vision damage that could occur when children under six view 3D video images. To quote, Toshiba's warning says that "due to the possibility of impact on vision development, viewers of 3D video images should be aged 6 or older."

science and technology

Science and technology has been the drive of the 21st century, Since the beginning of human civilization, science and technology has progressed in a continuous process. Science is an education process that allows the educated and creative minds to question, experiment or observe in an attempt to find answers, and then try to identify a set of unifying principles, concepts, and laws that embraces all phenomena of nature.

humanity by unveiling mysteries of how nature works. In the process we may make The aim is to better understand our universe and gain new knowledge that will enlighten new discoveries and inventions that change the way we think and/or create new technologies that transform our society.



Whether we like it or not, society is dependent on science and technology. The only way we can cram 6 billion people plus onto the earth and use resources at the rate we do, is through the support of scientific discovery and technology innovation. If we take our technology-based infrastructure away and civilization as we know the world would collapse. Perhaps more worrying, our dependency on science and technology is accelerating. The world’s population continues to grow, lifestyle expectations are going up, and supporting technologies are becomes increasingly sophisticated. But this “progress” can only be sustained through increasing the rate with which new discoveries are made and new technology innovations are implemented.

social media

Social media is a phrase being tossed around a lot these days, but it can sometimes be difficult to answer the question of what is social media. The best way to define social media is to break it down. Media is an instrument on communication, like a newspaper or a radio, so social media would be a social instrument of communication.

Social media is fast becoming a new type of therapy. Even if you have never been in therapy or counseling, we have all seen it played out in television, movies and books and know what therapists will ask.

Here are just a few phrases that will be familiar:

“Share your feeling”- Well then welcome to Facebook. Here is a place where you can share your personal thoughts, relationship status, list your friends and tell all your likes and dislikes. This is sharing for the masses.

“Tell me the first thing that comes to your mind”- The idea of free association is to get you in touch with yourself and is a perfect fit for Twitter. This site allows you to quickly toss out 140 character thoughts and share them with your audience 24/7.

Rorschach Test- “Look at this picture and tell me what you think”- This one can play out on a few sites. YouTube is the first that comes to mind where people post their videos and wait to see what everyone has to say when they add a comment. It’s also found on sites like Flickr and on your Facebook page where your friends and even the general public can share comments on your photos.

When people wonder why some are fascinated with social media it could be that they are intrigued by the new technology and others have found a new outlet that lets them save money on conventional therapy.

global warming

One of the major challenges of the 21st century is global warming.
Global warming is when the earth heats up (the temperature rises). It happens when greenhouse gases (carbon dioxide, water vapor, nitrous oxide, and methane) trap heat and light from the sun in the earth’s atmosphere, which increases the temperature. This hurts many people, animals, and plants. Many cannot take the change, so they die.

Greenhouse gases in the earth’s atmosphere that collect heat and light from the sun. With too many greenhouse gasses in the air, the earth’s atmosphere will trap too much heat and the earth will get too hot. As a result people, animals, and plants would die because the heat would be too strong.

Many things cause global warming.One thing that causes global warming is electrical pollution.Electricity causes pollution in many ways, some worse than others.In most cases, fossil fuels are burned to create electricity. Fossil fuels are made of dead plants and animals.Some examples of fossil fuels are oil and petroleum.Many pollutants(chemicals that pollute the air, water, and land) are sent into the air when fossil fuels are burned.Some of these chemicals are called greenhouse gases.

The government is doing many things to help stop global warming.The government made a law called The Clean Air Act so there is less air pollution. Global warming is making people get very bad illnesses that could make them disabled, very sick, and sometimes even die. The Clean Air Act is making many companies change their products to decrease these problems. Part of the law says that you may not put a certain amount of pollutants in the air. Hairspray and some other products, like foam cups, had this problem. Making and using these products let out too much volatile organic compounds (VOC’s), ozone-destroying chemicals (chlorofluorocarbons (CFC’s),and related chemicals (such as CO2) into the air. Now, almost all of these products have a label on them telling people what this product can do to the environment and many people.

The Clean Air Act has also made car companies change some of the things inside of the cars. Cars pollute a lot. While cars make more than half of the world’s smog (visible pollution in the air), many things that cars need to move and heat up make even more pollution. Some things that are inside of cars, buses, trucks, and motorcycles, like gasoline, pollute the air when the fuel is burned. It comes out as a chemical and when mixed in the air, forms smog.

Education in the 21st century

Education in the 21st century is flexible, creative, challenging, and complex. It addresses a rapidly changing world filled with fantastic new problems as well as exciting new possibilities. With improvement in science and technology, learning has been made simple and easily accessible, We now live in an increasingly diverse, globalized, and complex, media-saturated society.

Learning strategies in the 21st century make education simple and it shapes the mind of student to be a better leader, the strategies are :

To learn collaboration, work in teams.

To learn critical thinking, take on complex problems.

To learn oral communication, present.

To learn written communication, write.

To learn technology, use technology.

To develop citizenship, take on civic and global issues.

To learn about careers, do internships.

To learn content, research and do all of the above

Technology plays a critical role in supporting 21st Century learning environments. Providing one-to-one computing gives students and teachers the hardware and software tools to do their work. But even more profound is when technology, through the school’s network, provides a collaborative learning environment that houses curriculum, assessment rubrics, living grade books and communication tools.
