Demystifying the Difference Between Software Requirements and Software Specifications
In the realm of software engineering, two terms that often surface are software requirements and software specifications. While they are closely related, they hold distinct meanings and serve different purposes.
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 gbps.
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.
Read More: Write down briefly the history and importance of C 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.
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.
Use of integrated circuits (IC) started the third generation of computer. IC reduced the size, price, use of electricity etc. IC also facilitates speed and reliability of computers. Development of IC enabled organizing the whole central processing unit in single chip. Use of monitor also started in this generation. Operating system was improved to a new level and high speed line printers were in use. Followings are some of the characteristics of third generation.
