Wireless networking is an essential component of modern communication systems. Unlike wired networks, which use cables, wireless networks rely on radio waves to transmit data between devices. Understanding the basic principles of wireless communication is critical for CCNA students, as it helps in designing, configuring, and troubleshooting wireless LANs (WLANs). Introduction to Wireless Networking Wireless … Read more
In this section we describe the need for private IPv4 Addressing. Since, IPv4 address are categorised into public and private IP address. Public IP address is routable through global internet,while private IP address is The Need for Private IPv4 Addressing 1. The Core Problem: IPv4 Address Exhaustion The most pressing need for private IP addressing … Read more
Configuring and verifying IPv4 addressing and subnetting is and essential topic for network engineer and for CCNA Exams. IPv4 addressing provides unique identifiers for devices on a network, allowing them to communicate effectively. Subnetting divides a larger network into smaller, manageable subnets, improving network efficiency, security, and IP address utilization. Proper configuration ensures that each … Read more
Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) are transport layer (Layer 4 of OSI Model) protocols but serve different purposes in network communication. This article provides a detailed comparison of TCP and UDP, including their features, use cases, and key differences. Overview of TCP and UDP TCP and UDP are the major protocols … Read more
Identifying interface and cable issues is an important troubleshooting skill for network engineers. Network problems often occur due to faulty physical connections, so engineers must know how to detect and resolve them. This article will focus on the common issues of interfaces and cables due to collisions, errors, duplex mismatch or speed mismatch and their … Read more
In this section, we are going to describe the the physical interface and cabling types used in computer networking. What is Physical Interface in Networking Physical interfaces are the hardware ports on networking devices (routers, switches, firewalls, servers, etc.) that allow them to connect to other devices. Common Types of Physical Interfaces: The phyiscal interfaces … Read more
Network topology architecture defines overall view of network infrastructure how devices are interconnected in a network. For the CCNA 200-301 exam, you must understand different network topology architectures, including 2-tier, 3-tier, spine-leaf, WAN, SOHO, on-premises, and cloud-based networks. This tutorial explains each architecture, its use cases, advantages, and relevance in modern networking. What is Network … Read more
In modern networking, different devices work together to ensure seamless communication, security, and data transfer. For CCNA 200-301 Exam candidates, understanding the roles and functions of network components is crucial. This article explains the key devices—routers, switches, access points, firewalls, and endpoints—and how they operate in a network. 1. Roles and Functions of Routers Roles … Read more
