(#1–1) Fundamentals of Web Development - What is the Internet?
In modern society, Internet has become a crucial element to make our lives more convenient. Although we use the internet every day, it is not easy to explain exactly what the Internet is. So today let’s take a look at the internet.
according to Wikipedia, The Internet is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices.
Then, what is a network? anetwork consists of two or more computers are linked through cables or staterlites in order to share information. And Best example of a network is the internet which allows billion people from all over the world connected to share their resources from a distance.
-TCP/IP
the term “TCP/IP” stands for Transmission Control Protocol / Internet Protocol which communicate with computers on Internet using set of protocols or rules. More specifically, TCP/IP transport data packets (set of information) one network to another network. This protocol actually sent or receive data to the right destination.
TCP/IP is a combination of two separate protocols:
- Transmission Control Protocol (TCP)
- Internet Protocol (IP).
The Internet Protocol sent packets out over networks; it tells packets where to go and how to get there. IP has a method that lets any computer on the Internet forward a packet to another computer. We can think like a postman travel and deliver the postcards according to the destination.
The Transmission Control Protocol is responsible for ensuring the reliable transmission of data across Internet-connected networks. TCP checks packets for errors and submits requests for re-transmissions if any are found.
