High tech is technology that is at the cutting edge: the most advanced technology currently available. The adjective form is hyphenated: high-tech or high-technology. There is no specific class of technology that is high tech — the definition shifts over time — so products hyped as high tech in the 1960s would now be considered, if not exactly low tech, then at least somewhat obsolete. This fuzzy definition has led to marketing departments describing nearly all new products as high tech.
Technological convergence is the tendency for different technological systems to evolve towards performing similar tasks. Convergence can refer to previously separate technologies such as voice (and telephony features), data (and productivity applications), and video that now share resources and interact with each other synergistically.
A computer program (also software, or just a program) is a sequence of instructions written to perform a specified task with a computer. The program has an executable form that the computer can use directly to execute the instructions. The same program in its human-readable source code form, from which executable programs are derived (e.g., compiled), enables a programmer to study and develop its algorithms.
A computer network, often simply referred to as a network, is a collection of hardware components and computers interconnected by communication channels that allow sharing of resources and information. Networks may be classified according to a wide variety of characteristics such as the medium used to transport the data, communications protocol used, scale, topology, and organizational scope.
The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies.
