What is Internet 12th class?
Answer: A global system of interconnected computers, using a standardised Internet Protocol suite for communication and sharing information is called the Internet.
How do things travel on the Internet?
Data sent over the internet is called a message, but before messages get sent, they’re broken up into tinier parts called packets. These messages and packets travel from one source to the next using Internet Protocol (IP) and Transport Control Protocol (TCP).
What is Internet evolution?
The Internet is evolving. The majority of end users perceive this evolution in the form of changes and updates to the software and networked applications that they are familiar with, or with the arrival of entirely new applications that change the way they communicate, do business, entertain themselves, and so on.
What is the role of physics in media?
Physics allows us to understand the electromagnetic radiation we use to transmit data with fiber optics and satellites and to build computers that interpret those signals and transmit data on the Internet.
What is communication physics?
The communication system is a system which describes the information exchange between two points. The process of transmission and reception of information is called communication. The major elements of communication are the Transmitter of information, Channel or medium of communication and the Receiver of information.
What are the 3 features of Internet?
- Accessibility. An Internet is a global service and accessible to all.
- Easy to Use.
- Interaction with Other Media.
- Low Cost.
- Extension of Existing IT Technology.
- Flexibility of Communication.
- Security.
What are the 10 uses of Internet?
- Electronic mail. At least 85% of the inhabitants of cyberspace send and receive e-mail.
- Research.
- Downloading files.
- Discussion groups.
- Interactive games.
- Education and self-improvement.

What is Internet importance?
By utilizing the internet, people are able to progress in almost all spheres of life. As it’s a worldwide organization of the computer network, it can link people from all over and create communities. It’s a great way of providing and accessing information and is available almost all over the world.
Who controls the internet in the world?
No one person, company, organization or government runs the Internet. It is a globally distributed network comprising many voluntarily interconnected autonomous networks. It operates without a central governing body with each constituent network setting and enforcing its own policies.
Does internet travel at the speed of light?
The internet is such a slowpoke. In principle, it should operate at nearly the speed of light, which is more than 670 million miles per hour. Instead, internet data moves 37 to 100 times slower than that.
How far can data travel?
There are a few different versions of ethernet cable, but they all have a maximum distance of 100 meters (328 feet).
What will be the future of Internet?
The Internet of the Future Will Be Bigger, Faster, Safer, and More Private. Internet technology is no longer in its infancy. Spotty dial-up connectivity has given way to broadband, and the days of relying on wired connections are long gone, with many devices now able to connect to the web via wireless hubs.
What is the source of Internet?
Who created the internet? The internet began as ARPANET, an academic research network that was funded by the military’s Advanced Research Projects Agency (ARPA, now DARPA). The project was led by Bob Taylor, an ARPA administrator, and the network was built by the consulting firm of Bolt, Beranek and Newman.
How is Internet created?
ARPANET adopted TCP/IP on January 1, 1983, and from there researchers began to assemble the “network of networks” that became the modern Internet. The online world then took on a more recognizable form in 1990, when computer scientist Tim Berners-Lee invented the World Wide Web.
How is physics used in technology?
Physics is the most fundamental of all the sciences and has a wide range of applications to modern technologies. The importance of physics in modern technology can be recognized because it enables mobile devices, computers, televisions, watches, and many other modern technologies to operate in an automated manner.
What is the role of physics in information technology?
Solid state physics is responsible for semiconductors, which are responsible for semiconducting diodes and transistors, which are in turn at the heart of every memory chip and processor in every computer in the world.
How is physics and technology related?
Physics generates fundamental knowledge needed for the future technological advances that will continue to drive the economic engines of the world. Physics contributes to the technological infrastructure and provides trained personnel needed to take advantage of scientific advances and discoveries.
