Optical fiber is a type of dielectric (insulating) material, such as glass or plastic, capable of transporting light. High-speed data can be transmitted through optical fibers by total internal reflection of light. The biggest feature of optical fiber is that it transmits light signals instead of electrical signals. Currently available optical fibers have a data transmission rate of 100 Mbps to 2 Mbps.

In the 1970s, Dennis Ritchie Invented C programming language using Unix Operating system. C is being a high-level programming language. It is also called high-level structured programming language.

C language is one of the most popular computer languages today because it is a structured, high level, machine independent language. It allows software developers to develop software without worrying about the hardware platforms where they will be implemented.
A flowchart is a representation of a decision sequence or algorithm. This is a series of pictures that show how to proceed in order to solve a problem. Purpose of a flowchart is to show the flow of the program. The function is to show the steps of decision sequence or algorithm in the form of diagram.
Flowcharts have to be drawn using several geometric figures of different shapes. It helps to understand the nature of the program. Programmers use these charts of flows to compose programs.
Algorithm means step-by-step problem solving. That is, to break a problem into several steps and solve each step in turn to solve the entire problem.
A database management system is a software consisting of several programs. That is, the software that uses the database management system to store the records in different tables / files and through querying the relationship between multiple databases is called relational database management system. It consists of several interrelated files. This management system is used for database creation, control, maintenance etc.
Information technology is the technology of storing data or information and using the stored data.
The branch of technology concerned with the dissemination, processing and storage of information, especially by means of computers.
Oxford English dictionary
Information technology is basically an integrated technology which has emerged as information technology after long practice in communication, telecommunication, audio, video, computing, broadcasting and many other technologies.
