Routing protocols can generally be categorized into three types: Distance Vector Routing Protocols: These protocols determine the best path to a destination network based on distance or hop count. Examples include Routing Information Protocol (RIP) and Interior Gateway Routing Protocol (IGRP). Link-State Routing Protocols: These protocols build a detailed map of the network topology by … Read more
WPA2 (Wi-Fi Protected Access 2) is used to secure wireless networks, providing encryption and authentication mechanisms to protect data transmitted over Wi-Fi connections. It is widely used across home and enterprise networks to safeguard sensitive information such as passwords, financial transactions, and personal data from unauthorized access and interception by malicious actors. Between WPA and … Read more
A Wi-Fi controller, often referred to as a Wireless LAN Controller (WLC), serves as a centralized management device for wireless networks. Its primary use is to oversee and coordinate multiple access points (APs) within a wireless network infrastructure. The Wi-Fi controller enables administrators to configure, monitor, and manage Wi-Fi access points from a single interface, … Read more
The two main types of network security can be broadly categorized as preventive and detective measures. Preventive measures aim to stop security incidents from occurring by implementing controls such as firewalls, encryption, access controls, and authentication mechanisms. Detective measures, on the other hand, focus on identifying security breaches or incidents that have already occurred through … Read more
A wireless controller, such as a Wireless LAN Controller (WLC), functions by centralizing the management and coordination of wireless access points (APs) within a network. It operates as a dedicated device or software application that communicates with APs over the network. The WLC acts as a centralized point of control, allowing administrators to configure AP … Read more
Powerline networking utilizes existing electrical wiring within buildings to create a network connection. It allows devices to communicate and share data through the electrical outlets, effectively extending a network without the need for additional Ethernet cables or Wi-Fi signals. This technology is particularly useful in situations where Wi-Fi signals are weak or unreliable, or where … Read more
A LAN card, also known as a network interface card (NIC) or Ethernet adapter, is used to connect a computer or device to a local area network (LAN). Its primary function is to enable communication between the device and other devices or servers within the same LAN. The LAN card interfaces with the computer’s motherboard … Read more
SCTP (Stream Control Transmission Protocol) operates by providing reliable, message-oriented transport services between two endpoints in a network. Here’s how SCTP works: SCTP establishes and maintains associations between endpoints, similar to TCP connections. It supports both unicast and multicast communication. SCTP segments data into messages, each with its own sequence number for tracking and reordering … Read more
NFS (Network File System) is commonly used for sharing files and directories between Unix-like systems over a network. It allows remote systems to access files stored on a server as if they were local, facilitating centralized storage and collaboration among users and applications. NFS is particularly useful in environments where multiple clients need to access … Read more
Stream Control Transmission Protocol (SCTP) is a transport layer protocol designed to provide reliable, message-oriented communication between two endpoints in a network. SCTP offers features similar to both TCP (Transmission Control Protocol) and UDP (User Datagram Protocol), but with enhancements tailored for specific applications and network environments. The Stream Control Transmission Protocol (SCTP) is a … Read more
