How does information travels from the client to the server?
Data travels across the internet in packets. Each packet can carry a maximum of 1,500 bytes. Packets will travel from one machine to another until they reach their destination. As the packets arrive, the computer receiving the data assembles the packets like a puzzle, recreating the message.
Whats is a packet?
In networking, a packet is a small segment of a larger message. Data sent over computer networks*, such as the Internet, is divided into packets. These packets are then recombined by the computer or device that receives them.
What is raw packet?
Raw packet is used when you dont have any, the first bytes captured are directly the IPv6 or IPv4 header. Raw IP; the packet begins with an IPv4 or IPv6 header, with the “version” field of the header indicating whether it’s an IPv4 or IPv6 header.
How does a packet go from source to destination?
If we consider a basic network then routers are the main agents which play a vital role in forwarding the packet from source to destination. When the packet first leaves the source computer then the mac address of the relevant router (to which the packet is being transferred) is used as its destination mac address.
How does a packet travel from one router to another?
In this way the IP address information in the packet remains the same but the destination mac address changes from one router to another. So in this way, the packet travels from one router to another until it reaches the destination.
When does a data packet leave the source computer?
When the packet first leaves the source computer then the mac address of the relevant router (to which the packet is being transferred) is used as its destination mac address. When the packet reaches to that router, then the router performs the following action :
Where does the communication go from source port to destination port?
You are right : the communication goes from your computer (source port chosen “randomly”) to a web server (destination port 80). And from a web server (source port 80) to your computer (destination port xxxxx) for the server’s responses.
