Concept
Throughput is a measure of how much data or material can be processed by a system within a given time frame, reflecting the system's efficiency and capacity. It is crucial in evaluating performance across various fields such as manufacturing, telecommunications, and computing, where optimizing throughput can lead to enhanced productivity and reduced costs.
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
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.
Packet loss occurs when data packets traveling across a network fail to reach their destination, leading to network inefficiencies and degraded performance. It can be caused by network congestion, hardware failures, software bugs, or faulty network configurations, and is a critical factor in determining the quality of service in data transmission systems.
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.
Load balancing is a method used to distribute network or application traffic across multiple servers to ensure no single server becomes overwhelmed, thereby improving responsiveness and availability. It is critical for optimizing resource use, maximizing throughput, and minimizing response time in distributed computing environments.

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
Redundancy refers to the inclusion of extra components or information that are not strictly necessary, often to ensure reliability and fault tolerance. It is a crucial concept in various fields, from engineering and computing to linguistics and organizational design, where it helps prevent system failures and enhances communication clarity.
Quality of Service (QoS) refers to the performance level of a service, emphasizing the ability to provide predictable and reliable network performance by managing bandwidth, delay, jitter, and packet loss. It is crucial in ensuring optimal user experience, particularly in real-time applications like VoIP and streaming services.
Least Connections is a load balancing algorithm that directs traffic to the server with the fewest active connections, optimizing resource utilization and improving response times. It is particularly effective in environments where server loads are unpredictable and vary significantly over time.
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.
Source-specific Multicast (SSM) is a method of delivering information from a single source to multiple recipients over a network, where only the source and group address are needed to define the multicast group. This approach enhances security and efficiency by eliminating the need for receivers to specify which sources they want to receive data from, reducing unwanted traffic and simplifying routing protocols.
Statistical multiplexing is a method used in telecommunications to efficiently share bandwidth among multiple data streams by dynamically allocating resources based on the statistical properties of the inputs. This approach optimizes network performance and reduces congestion by taking advantage of the fact that not all streams will peak simultaneously.
Supernetting, also known as route aggregation, is a method used in networking to combine multiple IP networks into a single, larger network to reduce the number of routing table entries and improve efficiency. This technique is particularly useful in CIDR (Classless Inter-Domain Routing) to optimize the allocation of IP addresses and enhance the scalability of the internet routing system.
A multicast address is used in networking to deliver information to multiple destinations simultaneously, allowing efficient data distribution to multiple recipients. It is essential for applications like video conferencing, streaming media, and online gaming, where data needs to be sent to multiple users at once without unnecessary duplication.
Concept
A DHCP lease is a temporary allocation of an IP address to a device on a network, which is managed by the DHCP server to ensure efficient use of IP addresses. The lease duration determines how long a device can use the IP address before it must renew the lease or request a new one, preventing IP conflicts and optimizing network performance.
DNS caching is a process where DNS query results are temporarily stored to improve the efficiency and speed of subsequent requests to the same domain name. This reduces the load on DNS servers, minimizes latency, and enhances user experience by quickly resolving domain names to IP addresses from the cache.
DNS forwarding is a process where DNS queries are forwarded from one DNS server to another, often used to manage and optimize the resolution of domain names within a network. It enhances network efficiency and security by directing requests to specific servers, reducing the load on primary DNS servers and improving response times.
HTTP persistent connection, also known as HTTP keep-alive, allows multiple requests and responses between a client and server to be sent over a single TCP connection, reducing latency and improving network efficiency. This approach minimizes the overhead of establishing new connections for each request, thereby enhancing the performance of web applications.
Carrier Sense Multiple Access with Collision Detection (CSMA/CD) is a network protocol that helps manage data transmission over a shared communication channel by detecting and managing data collisions. It allows devices to sense if the channel is idle before transmitting and to stop and retry if a collision is detected, optimizing network efficiency in Ethernet environments.
Concept
A VLAN ID is a unique identifier used to distinguish between different Virtual Local Area Networks within the same physical network infrastructure. It allows for segmentation of network traffic, improving security and efficiency by isolating broadcast domains.
Concept
Link-State Advertisements (LSAs) are crucial components in OSPF (Open Shortest Path First) protocol, responsible for sharing routing and topology information among routers in a network. Different types of LSAs serve distinct purposes, such as conveying network topology, router links, and external routing information, ensuring efficient and accurate route computation.
Route summarization is a technique used in networking to reduce the size of routing tables by consolidating multiple routes into a single summarized route. This improves network efficiency by minimizing the amount of routing information that routers need to process and exchange, thereby optimizing bandwidth and reducing CPU load on routers.
Reverse Path Forwarding (RPF) is a technique used in multicast routing to ensure that multicast packets are forwarded through the network along the most efficient path, preventing loops and redundant packet forwarding. By checking if the incoming interface of a packet is the same as the interface that would be used to send packets back to the source, RPF ensures the integrity and efficiency of multicast distribution.
A Source-Based Tree is a data structure used in network routing, primarily for multicast communication, where the tree is constructed with the source node as the root. This structure optimizes the delivery of data packets from the source to multiple receivers by minimizing duplication and ensuring efficient path utilization.
Multicast distribution is a communication method used in computer networks to efficiently deliver data to multiple recipients simultaneously, minimizing the bandwidth usage compared to sending multiple individual streams. It is widely used in applications such as IPTV, online gaming, and stock exchanges where the same data needs to be transmitted to multiple users at the same time.
Group Management Protocol (GMP) is a network protocol used to manage multicast group memberships in a network, enabling efficient distribution of data to multiple recipients. It plays a crucial role in optimizing bandwidth usage by ensuring that data is only sent to networks with active group members.
