Access and trunk ports
In computer networking, access and trunk ports are two fundamental types of switch ports that manage network traffic differently. Access ports connect individual end devices to a single VLAN, while trunk ports carry traffic from multiple VLANs between network devices like switches and routers. Understanding these port types is essential for proper VLAN implementation and network segmentation in modern switched networks. Access Ports Access ports are the simplest type of switch port, designed to connect end devices such as computers, printers, and IP phones. Each access port belongs to exactly one VLAN, and all traffic from the ...
Read MoreEtherChannel in Computer Network
In modern computer networks, high availability and increased bandwidth are essential requirements. EtherChannel is a link aggregation technique used to combine multiple physical links into one logical link, providing enhanced performance and redundancy. What is EtherChannel? EtherChannel is a link aggregation technique that bundles multiple physical links between network devices into a single logical link. This creates a high-bandwidth connection while providing redundancy and load balancing capabilities. When multiple physical links are bundled together, they appear as a single logical interface to the network devices. EtherChannel Link Aggregation ...
Read MoreEthernet Transmitter Algorithm
The Ethernet Transmitter Algorithm is a comprehensive set of protocols and mechanisms that govern how data packets are transmitted over Ethernet networks. This algorithm ensures efficient data transmission while minimizing packet loss and maximizing network performance across local area networks (LANs). The algorithm encompasses multiple components working together to manage carrier sensing, collision detection, frame formatting, flow control, and quality of service. Understanding these mechanisms is essential for network administrators optimizing Ethernet network performance. Carrier Sense Multiple Access with Collision Detection (CSMA/CD) CSMA/CD is the fundamental access control mechanism in traditional Ethernet networks. Before transmitting, devices must ...
Read MoreExplain Parameter passing Semantics in RPC
Remote Procedure Call (RPC) is a communication protocol that enables a process running on one computer to invoke a procedure in another process running on a remote computer. The procedure call appears to the caller as a local procedure call, but in reality, the call is transmitted over a network. RPC involves several aspects such as marshaling of parameters, handling of return values, and communication between client and server. In this article, we will focus on parameter passing semantics in RPC. We will discuss various parameter passing methods and their characteristics, including pass-by-value, pass-by-reference, pass-by-result, and pass-by-object-reference. Parameter ...
Read MoreFast Recovery Technique For Loss Recovery in TCP
Transmission Control Protocol (TCP) is a widely used protocol for data transmission over the internet. However, data transmission over TCP is not always error-free. Transmission can be disrupted due to several reasons such as network congestion, packet loss, or failure of intermediate devices. In such cases, TCP uses a loss recovery technique to recover lost data and retransmit it. This technique is crucial in ensuring reliability of data transmission over the internet. Understanding TCP Loss Recovery TCP uses a three-way handshake mechanism to establish a connection between two devices. Once the connection is established, data transmission begins. TCP ...
Read MoreFeatures of Enhanced Interior Gateway Routing Protocol (EIGRP)
The Enhanced Interior Gateway Routing Protocol (EIGRP) is an advanced distance-vector routing protocol developed by Cisco Systems. It evolved from the Interior Gateway Routing Protocol (IGRP) to provide faster convergence, better scalability, and improved network efficiency for modern enterprise networks. Fast Convergence EIGRP's most significant feature is its rapid convergence using the Diffusing Update Algorithm (DUAL). When network topology changes occur, DUAL allows routers to quickly calculate loop-free backup routes and recover from link failures without the counting-to-infinity problem common in traditional distance-vector protocols. EIGRP Fast Convergence with DUAL ...
Read MoreFiber Optics Broadband Connection
In today's digital age, high-speed internet is no longer a luxury but a necessity. With growing demand for streaming services, video conferencing, and online gaming, traditional copper-based internet connections are becoming outdated. Fiber optics broadband connection has emerged as the go-to solution for reliable, high-speed internet that meets the needs of modern users. What is Fiber Optics Broadband Connection? Fiber optics broadband connection is an internet connection that uses fiber-optic cables to transmit data. Unlike traditional copper cables, which transmit data through electrical signals, fiber optics use light to transmit data. Fiber-optic cables consist of thin strands of ...
Read MoreFile Service Architecture in Distributed System
File Service Architecture in distributed systems is a fundamental framework that enables multiple users to access, share, and manipulate files across a network. This architecture provides the foundation for collaborative computing environments where data needs to be accessible from various locations and devices. The file service architecture operates on a client-server model where clients send requests to servers, which process these requests and return the requested data. This model ensures scalability, fault-tolerance, and reliability in distributed file systems. File Service Architecture Components File Client User Interface ...
Read MoreFile transfer protocol server configuration using cisco packet tracer
File Transfer Protocol (FTP) is a standard network protocol used for transferring files between computers over a network. FTP servers enable centralized file storage and sharing across organizations. This tutorial demonstrates how to configure an FTP server using Cisco Packet Tracer, a powerful network simulation tool that allows you to test configurations in a virtual environment before production deployment. Prerequisites and Network Setup Before configuring the FTP server, ensure you have Cisco Packet Tracer installed and create a basic network topology with at least one server device and one client device (PC or laptop). Connect these devices through ...
Read MoreDifference between LAN, MAN and WAN
When several computers are connected together and are able to communicate with one another, it is called a computer network. Computer networks are designed to share data and information among the computers of the network. Depending on the operating geographical area, computer networks are of three major types, namely LAN, MAN, and WAN. All three computer networks are designed for the same purpose of sharing information among computers. However, they differ significantly in coverage area, speed, cost, and complexity, which we will explore in this article. Network Types by Coverage Area ...
