Blog 4.3-Packet Switching Technology

      There are many users online all the time and data is being sent and received simultaneously. There was a need for a way in which to send information in a way that computers can understand that can be translated into usable information. The TCP allowed different messages to be sent over the internet via packets in any order that are reassembled later. When computer B wants to share info to computer D in the picture above, the binary data of the message sent from B is broken into manageable packets and delivered to D. The message sent from the computer B, uses TCP to send its message to computer C using package switching. The IP sets the format for the packet and the location it is to be sent and the IP information tells the router where this location is, then sends it. The packets travel independently and arrive out of order. Each packet has a header and it contains the destination and sending IP address as well as the order in which the packets are organized.
