Introduction to information technology
Information technology or IT industry is one of the fastest-growing industry in today’s technical world. It refers to the study, design, development, implementation, or management of information systems that are totally computer-based— especially software applications and computer hardware. In today’s world, from a small software design firm to a large manufacturer, everyone requires information technology to run their business. Almost all business firms have their individual IT Department to manage computer networks and other technical areas of their companies. Not only the computer and computer networks, but information technology also include mobile, telephone, television, and also the telecommunication industry.

Bandwidth for video hosting: Video conferencing solutions has become more common in big organizations to run their business. So more network bandwidth is required to support them sufficiently.
Information Technology vs. Computer Science
Computer Science focuses on efficiently programming computers. Mathematical algorithms are used by computer scientists. To implement these algorithms to computer software and hardware, computer scientists practice theoretical algorithms and practical problems that exist. Artificial intelligence(AI), computer graphics, programming, and software engineering are sub-fields of computer science.
On the other hand, Information Technology involves installing, organizing, and maintaining computer systems. Designing and operating databases and networks are also included in this.
