What are the Data Link Layer Communication Protocols in IoT?
IoT communication protocols are standardized rules that ensure secure and reliable data exchange between connected IoT devices. The Data Link Layer protocols specifically handle how data is transmitted over physical network links between adjacent network nodes. IoT devices can connect through IP networks or non-IP networks. IP-based connections offer wider range but consume more memory and power. Non-IP networks like Bluetooth require less resources but have limited range coverage. IoT Data Link Layer Protocol Stack Application Layer (MQTT, CoAP, HTTP) ...
Read MoreWhat are the components of the Data Communication System?
Data communication is the exchange of data between two or more devices via a transmission medium. It forms the backbone of modern networking and computing systems. For effective data communication to occur, five essential components must work together harmoniously. Each component plays a critical role in ensuring data is transmitted accurately and efficiently from source to destination. Components of Data Communication System Sender (Source) Message ...
Read MoreWhat are the differences between Apache and Nginx?
Let us understand the concepts of Apache and Nginx before learning the differences between them. Apache Apache HTTP Server is a widely-used, open-source web server developed by the Apache Software Foundation. It serves web pages to clients over the internet and is known for its reliability, security, and extensive feature set. Apache operates using a process-based architecture where each client request is handled by a separate process or thread. This makes it highly compatible with various programming languages and frameworks, but can consume more system resources under heavy traffic. Apache vs Nginx ...
Read MoreHow to Hack an Open WiFi?
The process of gaining unauthorized access to any data or system is commonly known as hacking. In networking contexts, this often involves identifying vulnerabilities in wireless networks and their security protocols. Types of Hacking Understanding the different types of hacking helps distinguish between legitimate security testing and malicious activities: White hat (Ethical Hacking) − Authorized security professionals who perform penetration testing to identify system vulnerabilities. Companies hire them legally to find and fix security weaknesses. Black hat (Malicious Hacking) − Unauthorized individuals who exploit system vulnerabilities for personal gain, data theft, or financial ...
Read MoreWhat are the differences between DTE and DCE?
Let us understand the concepts of Data Terminal Equipment (DTE) and Data Communications Equipment (DCE) before learning the differences between them. Data Terminal Equipment (DTE) At the physical layer, the function of DTE is to look for clocking from the device on the other end of the cable on a link and look for a frame-switching service. The device receives clocking from the DCE and uses it to synchronize data transmission. The customer devices or the DTE pass data from a host computer on a customer network for transmission over the Wide Area Network (WAN). DTE devices ...
Read MoreWhat are the differences between EIGRP and BGP?
Let us understand the concepts of Enhanced Interior Gateway Routing Protocol (EIGRP) and Border Gateway Protocol (BGP) before learning the differences between them. Enhanced Interior Gateway Routing Protocol (EIGRP) EIGRP is the enhanced version of IGRP protocol, incorporating all the features of IGRP while adding significant improvements. It overcomes IGRP's drawbacks including slow convergence, hop count limitations, and lack of Variable Length Subnet Masking (VLSM) support. In EIGRP, communication with neighboring routers occurs through Hello packets, while information exchange happens via Update packets. The protocol maintains a topology table containing path information and calculates the shortest path ...
Read MoreWhat is Adaptive Internet Protocol (AIP)?
Internet protocols are the set of rules that govern how data travels across networks. Data is transmitted in packets, each identified by an IP address that specifies its destination. While TCP and UDP are the most commonly used protocols, specialized protocols like Adaptive Internet Protocol (AIP) serve specific purposes in remote computing environments. Adaptive Internet Protocol (AIP) is a multichannel protocol designed to enable applications running on remote servers to be displayed and controlled from multiple client systems simultaneously. It provides a comprehensive solution for remote desktop access and application delivery. How AIP Works AIP establishes connections ...
Read MoreWhat are the TCP/IP Ports and its applications?
A port is a logical address that serves as a dedicated communication endpoint for network protocols. Think of it as a numbered mailbox where packets for specific applications are delivered and processed by the receiving device. TCP/IP ports are 16-bit numbers ranging from 0 to 65535 that work alongside IP addresses to uniquely identify network communications. While an IP address identifies the destination device, the port number specifies which application or service should handle the incoming data. TCP/IP Port Communication Client 192.168.1.10 Port: 12345 ...
Read MoreWhat are the differences between WiFi Extender and WiFi Booster?
Let us understand the concepts of WiFi extender and WiFi booster before learning the differences between them. WiFi Extender A WiFi extender, also called a wireless network extender or range extender, is a device that amplifies and rebroadcasts your existing WiFi signal to extend coverage to areas with weak or no signal. It works by receiving the original WiFi signal from your router, amplifying it, and then transmitting the boosted signal to cover dead zones in your home or office. The device uses both wired and wireless technologies to bring wireless connectivity to areas where network coverage ...
Read MoreWhat is Network Mapping or Nmap?
One of the most common challenges with modern network systems is their inherent complexity. Even a simple home network can be difficult to understand, while enterprise networks with hundreds or thousands of connected devices present exponentially greater complexity. Network Mapper (Nmap) is a powerful, free network discovery and security auditing tool that helps administrators understand their network infrastructure. It scans networks to identify active hosts, open ports, running services, operating systems, and other network characteristics, creating a comprehensive map of network topology and security posture. While Nmap can be misused by malicious actors to identify vulnerabilities, it serves ...
