An IP (Internet Protocol) address is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. It serves two main functions: host or network interface identification and location addressing. IP addresses enable devices to find and communicate with each other on a network, facilitating the transfer of data over the internet. There are two types of IP addresses: IPv4 (Internet Protocol version 4) and IPv6 (Internet Protocol version 6). IPv4 addresses are in the form of four sets of numbers separated by periods, while IPv6 addresses are more complex and were introduced to address the increasing demand for IP addresses.
A n I.B.M engineer, George Lauerer designed Universal Product Code as it visible on products we buy. Mr. Lauerer was asked to develop universal Product Code base on bull-eyed shaped code combination invented by N. Joseph Woodland in 1940. The purpose was that Universal Product Code would be printed on food labels and can be easily compatible with scanners, which was developed later on. Mr. George Lauerer, saw problem with the round shaped code, so he came up with the vertical shaped one that we see on food labels today! Universal Product Code (UPC) become available for scanners at the check out counters in after 1973. So, next time if you someone test your I.Q and asked who came up with universal Product Code, make sure you say, " Its George Lauerer !!!"
