The Basics of the Internet
The Internet allows us to quickly find information, communicate with friends and family around the world, manage our finances, shop, listen to music, watch videos, learn new things, play games and more. It is a global network of networks that connects millions of computers. Its creation was an incredible achievement that involved the collective work of thousands of individuals and organizations.
The core of the Internet is a set of networking standards called TCP/IP, which allow networks to communicate with each other. Software engineers Vint Cerf and Bob Kahn developed these protocols in the late 1960s. They worked on ARPANET, which was the first modern packet-switched network.
Today, the Internet connects billions of devices, including computers, tablets and smartphones. It also supports new kinds of applications like e-commerce, social networking, online video and streaming, and home automation systems. In addition to providing access to a wide range of entertainment, the Internet also enables people to do their jobs and schoolwork from anywhere with an Internet connection. A study by Deloitte found that a 10% increase in broadband access would result in more than 875,000 additional U.S. jobs and $186 billion in economic output.
When people use the Internet, they typically access websites, which are collections of related text, images or other resources. These sites are displayed in a program called a web browser. To get onto the Internet, a computer needs to have a special kind of connection, known as an Internet service provider or ISP. It can be delivered through cables, satellites or wireless connections.
Once a person is connected to the Internet, he can access any website that is stored on servers on the Web. The most popular websites are search engines, which make it easy to find information on the Internet. They let you type in one or more keywords and then display matching websites.
Another common activity on the Internet is email. People use it to communicate with colleagues and friends, stay up-to-date on news and events, and to share funny or interesting stories or photos. It is also possible to buy goods and services on the Internet, including clothing, cars, homes, and food.
Many people use the Internet to keep up with their hobbies, such as playing online games or watching sports. They can also use it to create online communities of people with similar interests. People can also use the Internet to learn and research topics that interest them, or to take courses and tutorials. Websites such as Wikipedia and YouTube are useful for learning new things.
The Internet brings the world closer together by allowing people to communicate with others from around the globe, and to find and share information and resources. However, it can also distract people from other activities, such as spending time with their families and friends. In addition, the Internet can be used for illegal purposes such as downloading pornography and other illicit material. As a result, there are some concerns that the Internet is becoming an unsafe place for children and teenagers.
