Worldwide system of computer networks

Table of Contents • • • • • A computer network is a system that connects two or more computing devices for transmitting and sharing information. Computing devices include everything from a mobile phone to a server. These devices are connected using physical wires such as fiber optics, but they can also be wireless. The first working network, called ARPANET, was created in the late 1960s and was funded by the U.S. Department of Defense. Government researchers used to share information at a time when computers were large and difficult to move. We have come a long way today from that basic kind of network. Today’s world revolves around the internet, which is a network of networks that connects billions of devices across the world. Organizations of all sizes use networks to connect their employees’ devices and shared resources such as printers. An example of a computer network at large is the traffic monitoring systems in urban cities. These systems alert officials and emergency responders with information about traffic flow and incidents. A simpler example is using Computer networking is the branch of computer science that deals with the ideation, architecture, creation, maintenance, and security of computer networks. It is a combination of computer science, computer engineering, and telecommunication. See More: Building a Disaster Preparedness Strategy?

The correct answer is Internet. Key Points • The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to link several billion devices worldwide. • A computer network is mainly of four types: • LAN(Local Area Network) • PAN(Personal Area Network) • MAN(Metropolitan Area Network) • WAN(Wide Area Network) Additional Information • Tim Berners-Lee, a British scientist, invented the World Wide Web (WWW)in 1989while working at CERN. • There are five types of topology in computer networks: • Mesh Topology. • Star Topology. • Bus Topology. • Ring Topology. • Hybrid Topology.

Chapter 1: Information Sciences 3 The Internet From https://en.wikipedia.org/wiki/Internet The Internet provides a great lens in which to study information sciences, as the Internet is the great enabler of our time. Regardless of discipline, understanding how the Internet can be used as an information and communication platform, for a wide variety of purposes, will help you be successful both in this class, and well beyond graduation and in the workforce. The Internet is the global system of interconnected computer networks that use the Internet protocol suite (TCP/IP) to link billions of devices worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and peer-to-peer networks for file sharing. The origins of the Internet date back to research commissioned by the United States federal government in the 1960s to build robust, fault-tolerant communication via computer networks. The primary precursor network, the ARPANET, initially served as a backbone for interconnection of regional academic and military networks in the 1980s. The funding of the National Science Foundation Network as a new backbone ...

Table of Contents • • • • What is a worldwide system of computers? The Internet, sometimes called simply “the Net,” is a worldwide system of computer networks — a network of networks in which users at any one computer can, if they have permission, get information from any other computer (and sometimes talk directly to users at other computers). What do we call a worldwide system of interconnected computers? The Internet (or internet) is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. What is TCP over IP? TCP/IP stands for Transmission Control Protocol/Internet Protocol and is a suite of communication protocols used to interconnect network devices on the internet. The TCP/IP protocol suite functions as an abstraction layer between internet applications and the routing and switching fabric. What does HTTP stand for?

A computer network comprises two or more computers that are connected—either by cables (wired) or WiFi (wireless)—with the purpose of transmitting, exchanging, or sharing data and resources. You build a computer network using hardware (e.g., routers, switches, access points, and cables) and software (e.g., operating systems or business applications). Geographic location often defines a computer network. For example, a LAN (local area network) connects computers in a defined physical space, like an office building, whereas a WAN (wide area network) can connect computers across continents. The internet is the largest example of a WAN, connecting billions of computers worldwide. You can further define a computer network by the protocols it uses to communicate, the physical arrangement of its components, how it controls traffic, and its purpose. Computer networks enable communication for every business, entertainment, and research purpose. The internet, online search, email, audio and video sharing, online commerce, live-streaming, and social networks all exist because of computer networks. As networking needs evolved, so did the computer network types that serve those needs. Here are the most common and widely used computer network types: • LAN (local area network): A LAN connects computers over a relatively short distance, allowing them to share data, files, and resources. For example, a LAN may connect all the computers in an office building, school, or hospital. Typically,...
