Concept
Communication protocols are a set of rules that allow two or more entities of a communication system to transmit information via any kind of variation of a physical quantity. They ensure reliable and secure data exchange, enabling interoperability between different systems and devices in a network.
Concept
Message Queuing is a communication method used in software architecture to enable asynchronous message passing between distributed systems or components. It enhances scalability and reliability by decoupling processes, allowing them to operate independently and handle messages at their own pace.
Concept
Latency refers to the delay between a user's action and the corresponding response in a system, crucial in determining the perceived speed and efficiency of interactions. It is a critical factor in network performance, affecting everything from web browsing to real-time applications like gaming and video conferencing.
Concept
Concurrency is the ability of a system to handle multiple tasks simultaneously, improving efficiency and resource utilization by overlapping operations without necessarily executing them at the same time. It is essential in modern computing environments to enhance performance, responsiveness, and scalability, especially in multi-core processors and distributed systems.
Concept
Real-time communication refers to the instantaneous exchange of information between parties, enabling immediate feedback and interaction. It is crucial in applications where time-sensitive data is transmitted, such as video conferencing, live streaming, and online gaming.
Concept
Event-driven architecture is a software design paradigm where the flow of the program is determined by events such as user actions, sensor outputs, or messages from other programs. This architecture enables systems to be more scalable, responsive, and easier to maintain by decoupling event producers from event consumers.
Concept
Scalability refers to the ability of a system, network, or process to handle a growing amount of work or its potential to accommodate growth. It is a critical factor in ensuring that systems can adapt to increased demands without compromising performance or efficiency.
Concept
Blocking I/O operations halt the execution of a program until the operation is completed, which can lead to inefficiencies in resource utilization. Non-blocking I/O allows a program to continue executing other tasks while waiting for the I/O operation to complete, enhancing performance by utilizing asynchronous processing techniques.
Concept
The client-server model is a distributed application structure that partitions tasks or workloads between service providers, known as servers, and service requesters, called clients. This model allows multiple clients to access shared resources on a network, providing scalability, centralized control, and resource management.
Concept
Network topology refers to the arrangement of different elements (links, nodes, etc.) in a computer network. It is crucial for determining the performance, scalability, and fault tolerance of the network infrastructure.
Concept
Sequence diagrams are a type of UML diagram used to illustrate how objects interact in a particular sequence of events within a system. They provide a clear visualization of the order and timing of messages exchanged between objects, making them essential for understanding system behavior and communication flow.
