EIGRP (Enhanced Interior Gateway Routing Protocol) and OSPF (Open Shortest Path First) are both routing protocols used in computer networks, but they differ in their operation and deployment scenarios. EIGRP is a proprietary Cisco routing protocol designed for efficient routing within enterprise networks. It uses a hybrid routing protocol that combines the benefits of distance-vector … Read more
The principle of fiber optics revolves around the transmission of light through thin, flexible strands of glass or plastic fibers. These fibers are designed to guide light along their length by using the principle of total internal reflection. When light enters the core of the fiber at a shallow angle, it undergoes multiple internal reflections … Read more
Fibre optics is also known as optical fiber or fiber optics. These terms are used interchangeably to describe the technology and method of transmitting light signals through thin, transparent fibers made of glass or plastic. Another word for fibre optics is “optical communication.” This term emphasizes the use of light signals to transmit data over … Read more
Network-connected devices refer to electronic devices or systems that have the capability to connect to a computer network. These devices include computers, smartphones, tablets, printers, smart TVs, IoT (Internet of Things) devices, and more. By connecting to a network, these devices can communicate with each other and access shared resources such as files, printers, and … Read more
The role of SMB (Server Message Block) is to facilitate file sharing, printer sharing, and inter-process communication (IPC) between devices on a network. It is a protocol used primarily by Microsoft Windows operating systems but also supported by other operating systems like Linux and macOS through implementations like Samba. SMB allows computers and devices to … Read more
WPA2 (Wi-Fi Protected Access 2) and WPA3 (Wi-Fi Protected Access 3) are security protocols used to secure wireless networks, specifically Wi-Fi connections. WPA2 has been the standard for securing Wi-Fi networks for many years. It uses the AES (Advanced Encryption Standard) protocol for encryption and offers robust security features such as encryption keys and authentication … Read more
Network File Storage (NFS) refers to a distributed file system protocol that allows a client computer to access files over a network as if they were stored locally. NFS enables remote file sharing and access between computers in a networked environment, regardless of their operating systems. It operates on a client-server model, where the NFS … Read more
The purpose of the IDS (Intrusion Detection System) is to monitor network traffic for suspicious activities and potential threats, alerting administrators when it detects unusual or malicious behavior. The purpose of the IPS (Intrusion Prevention System) is to monitor network traffic for suspicious activities and take immediate action to block or prevent malicious activities from … Read more
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
