ARP (Address Resolution Protocol) and RARP (Reverse Address Resolution Protocol) are networking protocols used to map IP addresses to MAC addresses and vice versa. Here’s a brief explanation of ARP and RARP, including their resolution process, packet format, and encapsulation: ARP (Address Resolution Protocol): Resolution Process: When a device in a network wants to communicate […]

Introduction to Network Operating System(NOS)

A network operating system (NOS) is a specialized software that provides the necessary functions and services to manage and operate a computer network. It is designed to support and coordinate multiple devices, users, and applications within a networked environment. Here is an introduction to network operating systems: 1. Network Management: A NOS facilitates the management […]

Types of connectivities in Computer Networks

Here are different types of connectivity options commonly used in networking: 1. Dial-up: Dial-up connectivity uses a modem and a telephone line to establish a connection to the internet or a remote network. It is a relatively slow and outdated method that is primarily used in remote areas where broadband options are limited. 2. Digital […]

It provides a framework for organizing and connecting various devices and network equipment in a reliable and efficient manner. Here are some key concepts and components associated with structured cabling: Concept of Structured Cabling: Structured […]

Networking Devices

Networking devices play a crucial role in the functioning and connectivity of computer networks. Here are some commonly used networking devices: 1. Network Interface Card (NIC): A Network Interface Card, also known as a network adapter or network card, is a hardware component that allows a computer to connect to a network. It enables the […]

Networking Media

Networking media refers to the physical means through which data is transmitted in a computer network. There are several types of networking media commonly used, including: 1. Coaxial Cable: Coaxial cable consists of a central conductor surrounded by an insulating layer, a metallic shield, and an outer insulating layer. It is commonly used for cable […]

Class Full Addressing

Classful addressing refers to the original method of IP address allocation in IPv4, which divided the available IP address space into five classes: Class A, Class B, Class C, Class D, and Class E. Each class had a predefined range of network and host addresses, providing a structure for addressing and routing. Different classes in […]

IP Addresses

IP Addresses, or Internet Protocol Addresses, are unique numerical identifiers assigned to devices connected to a network. They play a crucial role in network communication, allowing devices to send and receive data across the Internet or other interconnected networks. Here are some key points about IP addresses: Format of IP addresses: IP addresses are typically […]

Network Address

Network Address Overview: A network address is a unique identifier assigned to a device or a network interface on a computer network. It enables devices to communicate and exchange data within a network or across different networks. Network addresses are essential for routing data packets and establishing connections between devices. Types of Addresses: 1. IP […]

LAN and WAN Protocols

LAN (Local Area Network) and WAN (Wide Area Network) are two types of networks commonly used in computer communications. Here’s an introduction to various protocols used in LAN and WAN environments: LAN Protocols: 1. Ethernet: Ethernet is the most widely used LAN protocol. It defines the physical and data link layer specifications for wired LANs. […]
