Internet Basics – What is the Internet?

The Internet is a broad network that connects computers all around the globe. Through the Internet, individuals can share data and communicate with each other from anywhere by utilizing a high-speed Internet connection. The Internet has created the possibility of a “virtual community” where people from different countries can interact. For instance, bloggers can have conversations online with people in China, while doctors can discuss patients in India.

The Internet allows users to access content from all over the world at the same time. The Internet has a lot of uses such as surfing the Internet using a web browser, sending e-mails, sending text and picture messages, and connecting to other wireless networks. One of the most widely used elements of the Internet is the transmission control protocol (TCP), which controls the way data is transmitted over the Internet.

There are four different types of Internet protocols: ICMP, IP, TCP, and SMTP. ICMP is the most basic form of Internet networking. ICMP uses port numbers to identify each computer on a network. In ICMP, one message is sent for every possible combination of ports and the recipient is informed of the state of the corresponding computer. ICMP is usually sent through one type of IP packet and one type of TCP connection.
