The internet is the worlds largest wide are network (WAN), which is made up of many smaller networks. EVERYTHING you find online comes from the internet. The internet is uses for many tasks, such as research, information, communication, and entertainment. Billions of people are internet users which we currently use today on a daily basis. Without the internet, we would be many steps back in today's society.
2. What is a protocol?
Network protocols are rules for how computers in a network communicate with each other. They control or enable connection, communication, and data transfer between two computing endpoints. The first network protocol (file transfer protocol) was used for email. Second, was the TCP/IP which was used for exchanging data. These define what data packets look like on the Internet and how they are sent and received. HTTP and FTP control more specific data formats and messages used by the network.
3. What is DNS?
DNS stands for Domain Name Service. These services are required to transport domain names to the IP address that the Internet uses to locate a computer. It is also required in order to have Internet communication even exist. DNS look up the host name and returns the IP address, BUT also does the opposite vise versa.
