Packet switching Internet is a packet switched network
{"Image DocumentName": "Packet switching Internet is a packet switched network", "Image ImageDescription": "Data is split into packets. Each packet has a source IP/port, and a destination IP/port, as well as other meta-information. Packets may not arrive in the same order as sent. Packets may not even arrive at all. Suppose you need to send a five page letter home, but all you\u2019ve got is a stack of postcards. So you put a bit of the letter on each postcard, number them (so they can be put back in the right order when they\u2019re received), address them, and put your name on them. Then you put them in the post, and hope that they all arrive. That\u2019s, broadly, how a packet switched network works. Without all the tedious business of having to think of something interesting to say about your holiday.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
