Information technology (IT) is a set of related fields that
encompass computer systems, software, programming languages and data and
information processing and storage.
In computer science, imperative programming is a programming paradigm of
software that uses statements that change a programʼs state. In
much the same way that the imperative mood in natural languages
expresses commands, an imperative program consists of commands for the
computer to perform.
Imperative programming focuses on describing how a program operates step by step, rather than on high-level descriptions of its expected results.
The term is often used in contrast to declarative programming, which focuses on what the program should accomplish without specifying
all the details of how the program should achieve the result.
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.
It is a network of networks that consists 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 a vast range of information resources and services,
such as the interlinked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing.
