How data travels over the internet
Data travels over the internet through a system of interconnected networks. Each network is made up of routers, switches, and other hardware that directs and transmits data packets to their destination.
When a user sends data, such as a search request or an email, the data is broken up into small packets and sent to the nearest router. The router examines the destination address of the packet and determines the best path for the data to take to reach its destination. The packet is then forwarded to the next router, which continues to examine the destination address and forward the packet to the next router, until the packet reaches its destination.
The process of transmitting data over the internet is known as “packet switching”. This allows for more efficient use of network resources and makes it possible for data to be transmitted over long distances.
The transmission control protocol (TCP) and the user datagram protocol (UDP) are two common protocols used to ensure that data is transmitted in a reliable and efficient manner. TCP is used for applications that require a reliable and ordered delivery of data, such as file transfers and email. UDP is used for applications that do not require a guaranteed delivery of data, such as video streaming and online gaming.
In summary, data travels over the internet through a system of interconnected networks, where it is broken up into small packets and transmitted to its destination through a process of packet switching.
