Long-term evaluation refers to the assessment and analysis of outcomes, impacts, or effectiveness of a program, project, or intervention over an extended period. It involves tracking and measuring results over months or years to understand sustained effects, identify trends, and determine the long-term viability or success of the initiative. Long-term evaluations provide insights into the … Read more
Near Field Communication (NFC) operates on the principle of electromagnetic induction, where devices equipped with NFC technology can establish communication by bringing them close together, typically within a few centimeters. The principle behind NFC involves two components: an initiator device that generates a radio frequency (RF) field and a target device that responds to this … Read more
Fidelity in technology refers to the accuracy, reliability, and faithfulness with which a technology or system reproduces or represents the original input or source. It denotes how closely the output or performance matches the intended or expected result without distortion, loss of detail, or deviation from the original specifications. High fidelity in technology ensures that … Read more
NAS, which stands for Network Attached Storage, is known for its role in providing centralized data storage and access for multiple devices within a network. It allows users to store, manage, and share files, documents, media, and other data types across computers, servers, and devices connected to the same network. NAS devices are equipped with … Read more
Internet of Things (IoT) refers to the network of physical devices, vehicles, appliances, and other items embedded with electronics, software, sensors, actuators, and connectivity which enables them to connect, collect, and exchange data. This creates opportunities for direct integration of the physical world into computer-based systems, resulting in improved efficiency, accuracy, and economic benefit. Internet … Read more
In Windows, the network file system primarily used is the Server Message Block (SMB) protocol. SMB is the native file sharing protocol developed by Microsoft for sharing files, printers, and other resources between computers running Windows or other compatible operating systems within a network. It supports various versions, with SMB 3.1.1 being the latest as … Read more
SDN, or Software-Defined Networking, simplifies the management and operation of networks by decoupling the network control plane from the forwarding plane. In simpler terms, it allows administrators to manage network traffic from a centralized software application rather than configuring each network device individually. SDN is defined as an approach to networking that separates the control … Read more
An IGMP proxy is used in network environments to manage and optimize multicast traffic flows between different network segments or VLANs. Multicast traffic involves transmitting data packets from one source to multiple recipients simultaneously, which is efficient for applications like video streaming, online gaming, or software updates where the same content needs to be delivered … Read more
CDNs (Content Delivery Networks) can be broadly categorized into two types: public CDNs and private CDNs. Public CDNs are operated by third-party providers and are accessible to multiple users or organizations. They typically offer services on a pay-as-you-go basis and are widely used for delivering web content, streaming media, and other online services globally. The … Read more
LLDP (Link Layer Discovery Protocol) works by enabling network devices, such as switches, routers, and endpoints, to discover and exchange information about their identities, capabilities, and neighbors within a local area network (LAN). When a device supports LLDP, it periodically sends out LLDP advertisements known as “LLDPDUs” (Link Layer Discovery Protocol Data Units). These advertisements … Read more
