There is no doubt that the Internet is the precursor of today's technology. Thanks to this we can obtain any type of information in fractions of seconds with the advantage of downloading it or sending it to other people. However, data transfer from one point to another could not be efficient without a router. According to CISCO, the router “acts like a dispatcher, choosing the best path for information to flow so that it is received quickly.” In everyday life, a router works in the same way as a post office. Both receive packets, analyze the addresses and then send them to the correct destinations. This whole process makes the transportation of information faster and more secure across a large network. Speculation exists as to whether the Internet was a product of military defense against the Soviet Union during the Cold War or whether it was simply the development of an idea. Certainly, the beginnings of the Internet began with the Advance Research Project Network, also known as ARPA. According to www.nehistory.info: “ARPANET was about time sharing. Timesharing attempted to allow research institutions to use the processing power of other institutions' computers when they had large calculations that required more power. These researchers and scientists were trying to find a way to connect different computers at the same time in order to share information and resources. Therefore, they could minimize information processing time. Throughout the development of this research, ARPA gave birth to the idea of ​​Packet Switching, which involves dividing information into smaller parts. For this reason, the name packet is assigned to information that we send from a source to a...... middle of paper ......so the information would go to unintended destinations. In addition, the router saves a lot of time since it transfers information in fractions of seconds. However, without this device, we would need a tape containing information to transfer it from one place to another, like the people at Stanford University did before William Yeager invented the router. a router http://www.cisco.com/cisco/web/solutions/small_business/resource_center/articles/connect_employees_and_offices/what_is_a_network_switch/index.html Internet History Online: The Beginnings of the Internet by Ian Peter http:// www.nethistory.info/History%20of%20the%20Internet/beginnings.html Network World: Router Manhttp://www.networkworld.com/supp/2006/anniversary/032706-routerman.html?page=2
