What is Internet processing?
Internetworking is a practice of connecting multiple computer networks together and creating larger networks. Different types of networks can be associated with intermediate devices known as gates and once connected, they work as the only large network. Internetworking has been developed in response to several questions they encounter in the first days of personal computers and form the basis of modern Internet.
Many people use different types of networks every day without realizing it. An entrepreneur who uses a smartphone to check the email uses a cell network, while a home user can stream music into a laptop via a wireless network. Rural users could access the network of Internet service providers in the context of dialing, in the business world they are the standard of large cable networks. Internetworking allows all of these networks to interconnect despite their technological differences.
The key to bridge different types of networks is the concept of packets - the individual data unit. PacketsThey are the basis for modern computer networks, but are not limited to any network technology. Instead, packets can be inserted into so -called images that are designed for specific network technologies. This arrangement allows you to use packets from any type of network in any other type of network. Special devices that support more than one network technology called gates or routers can transmit packets between these different networks.
Internetworking has gradually evolved in response to several challenges. The earliest connections between multiple computers were "stupid" computing performance terminals that would connect to large powerful hall computers. Because personal computers (PC) began to replace terminals, the PC were grouped into local areas (Lans). Although it had many advantages, the ropes were isolated and other Lans could not be connected to reduce productivity. File servers, printers and other sources could not beT shared between places and organizations with multiple places could not easily exchange information.
At the beginning of the 70s, American scientists working on the network financed by the Defense Department, known as the Advanced Research Project Agency Network (Arpanet), began to examine the possibility of connecting their network with other early networks. These research realized that early network protocols were not suitable for Internet processing and the development of the Transmission and Internet Protocol (TCP/IP) protocol began. At the end of the 1970s, Arpanet was linked to two other networks using TCP/IP and a key page was written in the Internet history.
The new networks were continued to be associated with Arpanet and the growing number of ropes was connected to each other through the Arpanet. In 1989, the National Science Foundation network (NSF) was replaced by Arpanet. From there, regional networks were connected to the NSF network using TCP/IP and related protocols and a large "network network" - the Internet.
