Concept
Network links are the physical or logical connections that enable data transfer between nodes in a network, serving as the backbone for communication and information exchange. They can vary in type, such as wired or wireless, and are characterized by their bandwidth, latency, and reliability, which directly impact the efficiency and performance of the network.
Concept
Bandwidth refers to the maximum rate of data transfer across a given path, crucial for determining the speed and efficiency of network communications. It is a critical factor in the performance of networks, impacting everything from internet browsing to streaming and data-intensive applications.
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
Data transmission is the process of sending digital or analog data over a communication medium to one or more devices, ensuring accuracy and integrity during the transfer. It is fundamental to modern communication systems, enabling the exchange of information across networks and supporting various applications from internet browsing to telecommunication services.
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
Protocols are formalized rules and conventions that govern the exchange of information between systems, ensuring interoperability and communication efficiency. They are fundamental in various domains, including computer networks, where they define the syntax, semantics, and synchronization of communication processes.
Concept
Packet switching is a method of data transmission where data is broken into smaller packets and sent over a network independently, allowing for efficient use of bandwidth and reducing transmission latency. This approach contrasts with circuit switching, where a dedicated communication path is established for the duration of the session.
Concept
Routing is the process of selecting paths in a network along which to send data packets, ensuring efficient and reliable communication between devices. It involves the use of algorithms and protocols to determine the best path based on factors like network topology, traffic load, and link costs.
Concept
Network security involves implementing measures to protect the integrity, confidentiality, and availability of computer networks and data. It encompasses a variety of technologies, devices, and processes to defend against unauthorized access, misuse, malfunction, modification, destruction, or improper disclosure of network resources.
Concept
Quality of Service (QoS) is a set of technologies and techniques used in networking to manage bandwidth, reduce latency, and ensure the reliable delivery of data across a network. It is crucial for optimizing the performance of applications, particularly those requiring real-time data transmission like video conferencing and VoIP.
Concept
Internet Protocol (IP) is a set of rules governing the format of data sent over the internet or other network. It is responsible for addressing and routing packets of data so that they can travel across networks and arrive at the correct destination.
Concept
Ethernet is a widely used networking technology that facilitates data communication over local area networks (LANs) by using a set of protocols to control how data is transmitted and received. It provides a reliable and efficient method for connecting devices within a network, utilizing both wired and wireless connections to ensure seamless data exchange.
Concept
Wi-Fi is a wireless networking technology that uses radio waves to provide high-speed internet and network connections. It enables devices such as smartphones, laptops, and tablets to connect to the internet without the need for physical cables, facilitating mobility and convenience in accessing digital information.
Concept
Fiber optics is a technology that uses thin strands of glass or plastic fibers to transmit data as light signals over long distances with minimal loss. It is widely used for high-speed internet, telecommunications, and medical imaging due to its high bandwidth and resistance to electromagnetic interference.
