Internet - origins of the name can be found in two different words - interconnection and network, combined together as inter-network. The neologism was later shortened into simple "internet".

Internet is a global, worldwide computer network, often proclaimed as "network of the networks". In IT terminology Internet is being referred as space of IP addresses, assigned to particular hosts and servers connected by network devices like NIC, modems, hubs and access-points, communicating with each other using transmission control protocol/ internet protocol (TCP/IP). Origins Internet was invented in the United States of America for the science and academic environment. It was made as an expansion of the ARPANet network, later provided to other scientific facilities and companies. Internet became widely accessible for worldwide individual users in the end of 90's. Also, the RAND Corporation had it's influence in the early beginnings of Internet. Their research for the ways of communication between commanders in times of nuclear war, was the first step to create an idea of connecting networks into one, which was proclaimed In 1973 by R.Kahn and V.Cerf, and later expanded by ARPANet chief director, Charles Herzfeld.
