A Virtual Private Network (VPN) is a technology that creates a secure and encrypted connection over a less secure network, typically the internet. It allows users to securely access and transmit data between their devices (such as computers, smartphones) and a private network (like a corporate network) as if they were directly connected to that … Read more
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
DNS (Domain Name System) rules refer to the guidelines and configurations that govern the operation and management of DNS within a network or organization.

Denial of service (DoS) refers to a cyberattack that aims to disrupt or temporarily suspend the services of a host connected to the internet, typically by overwhelming the target system with a flood of malicious traffic. This flood of traffic can exhaust system resources such as bandwidth, processing power, or memory, rendering the system unavailable … Read more
Ethernet transmits data using a protocol called the Ethernet protocol, which is part of the IEEE 802.3 standard. It employs a method known as packet switching, where data is divided into smaller units called frames. Each frame contains the destination and source addresses, as well as error-checking information to ensure data integrity. Frames are transmitted … Read more
DDoS, or Distributed Denial of Service, is a type of cyberattack where multiple compromised systems, often infected with malware and controlled remotely by attackers, are used to flood a target system or network with overwhelming traffic. This flood of traffic can exhaust the target’s resources such as bandwidth, processing power, or memory, leading to a … Read more
