Definition of Internet and Intranet

Understanding Internet.

Internet is the abbreviation of interconnected networking, networking system that connects millions of computers around the world. The Internet allows the transfer of data between computers despite long distances apart. The Internet can be used as a means of exchanging information from one computer to another in a short time, without being restricted by the physical distance the second computer. Simply put, the Internet can be defined as a network of networks (network of networks). The Internet is a global communication system that connects computers around the world. Basically, the Internet is a collection of two or more computers around the world to form a network of interconnected computers. Antarnode connecting lines in the form of so-called Internet backbone transmission media such as cable, fiber optic, and microwave (microwave). TCP / IP (Transmission Control Protocol / Internet Protocol) is a major standard Internet network that can unify the various computer languages ​​and codes in the world. In terms of education, the Internet is like a large and comprehensive library in which there are millions and even billions of information in the form of text, image, animation, video, and sound.

History of the Internet.

            Internet was originally a computer network established by the Department of Defense of the United States in 1969 through a project ARPA (Advanced Research Project Agency) decided to conduct research on how to connect a computer to form an organic network. This research program known as ARPANet. The first network was built to connect 4 places, UCLA (University of California Los Angeles), UCSB (University of California Santa Barbara), University of Utah, and SRI (Stanford Research Institute).
Until 1972, this network connects more than 20 computers. ARPANet be internetworking backbone for educational institutions, research, industry, and contractors primarily relating to military networks. Wireless networks (wireless) is growing rapidly, ranging from technology WiFi (Wireless Fidelity), GPRS (General Packet Radio Service), to 3G (third generation technology) we can already enjoy. Wireless network has a very high access speed compared to wired networks. Common activities are usually carried out by the Internet, among others browsing / surfing, searching, e-mail, chat, download, and upload. On the Internet available bemacam of facilities ie, Browsing, Searching, E-mail, Chat, Download and Upload.

Understanding Intranet.

            Intranet is a computer network built by adopting Internet technology. Inside there Intranet web applications and data communications technology. In terms of coverage, Intranet can work widely and most like the Internet. Intranet applications and information intended for a specific organization, in contrast to information from Internet sites devoted to the general public. Intranet connected to the Internet to enable the exchange of information and data with others via Intranet network backbone Internet.
