System Modeling in Software Engineering​

Comments 7,627 Comments

System modelling is a critical process in software engineering and various other fields that involves creating simplified, abstract representations of complex systems. The primary purpose of system modelling is to understand, analyze, and communicate the structure, behaviour, and interactions of a system. Graphical Modeling Graphical modelling is a method of representing information, systems, or processes using visual elements such as diagrams, charts, graphs, and symbols. It is a way to convey complex concepts, relationships, and structures in a more intuitive…

Packet and Frames in Computer Networks

Comments 23 Comments

Packets, frames, and error detection are fundamental concepts in computer networking and data communication. These terms are used to describe how data is structured, packaged, and transmitted in a network, as well as how errors in data transmission are identified and handled. Let’s explore these concepts: What are Packets? A packet is a small unit of data that is transmitted over a network. It typically includes both the data to be sent and control information, such as the source and…

Software Requirement Engineering

Comments 1 Comment

Software requirements are detailed descriptions of the functions, features, constraints, and qualities that a software system must possess to fulfil its intended purpose and meet the needs of its users and stakeholders. These requirements serve as a bridge between the expectations of the users and the technical specifications that software developers use to design, build, and test the software. Jones defines software requirements as a statement of needs by a user that triggers the development of a program or system….
