What is Computer Network Architecture?
A network model represents the organization of multiple computers in a network. It describes how individual computers are interconnected and communicate with each other to share resources and services. Computer network architecture defines the structural design and operational framework that governs how networked systems interact. Let's explore the main types of network architectures. Centralized Computing Architecture In centralized computing architecture, one powerful computer (mainframe) serves multiple low-powered client devices. All processing power and data storage are concentrated in the central server. Central processing − All computational tasks are performed by the mainframe computer. Terminal connections ...
Read MoreWhat is Client-Server Architecture in Computer Network?
In Client-Server Architecture, a specific computer designated as a server provides various services to other computers known as clients. The server acts as a service provider, while the client acts as a service requester. When a client requests information from the server, the server processes the request and responds with the appropriate data or service. Client-Server Architecture Client 1 Client 2 Server Provides ...
Read MoreWhat is LAN (Local Area Network) in Computer Network?
A Local Area Network (LAN) is a computer network that connects devices within a limited geographical area, typically spanning a single building, office, or campus. LANs are privately owned networks that enable local connectivity and resource sharing among connected devices. LANs are commonly used in homes, offices, schools, and small businesses to connect personal computers, printers, servers, and other network devices. They facilitate efficient data transfer and resource sharing within the local environment. Local Area Network (LAN) Structure Switch/Hub ...
Read MoreWhat are the Advantages and Disadvantages of LAN in Computer Network?
A Local Area Network (LAN) is a computer network that connects devices within a limited geographical area such as a building, office, or campus. Understanding the advantages and disadvantages of LAN helps organizations make informed decisions about network implementation. LAN Network Components Computer 1 Computer 2 Printer Server Switch Advantages of LAN ...
Read MoreWhat is WAN (Wide Area Network) in Computer Network?
A Wide Area Network (WAN) is a computer network that connects two or more computers across large geographical distances, spanning cities, countries, or even continents. Unlike LANs, WANs utilize public networks such as telephone systems, microwave broadcasts, or satellite communications for connectivity. WAN Architecture LAN A WAN Infrastructure LAN B LAN C ...
Read MoreExplain the functions of WAN in Computer Network
A Wide Area Network (WAN) serves multiple critical functions that enable organizations to connect geographically dispersed locations and resources. These functions make WANs essential for modern business operations and global communications. Key Functions of WAN Remote Data Entry Centralized Information Global Communication Resource Sharing WAN Core Remote ...
Read MoreWhat is Fully-Interconnected Network Topology?
A Fully-Interconnected Network Topology, also known as a mesh topology, is a network design where every node is connected to every other node through dedicated point-to-point links. This creates a complete network where each device has direct communication paths to all other devices without requiring intermediate nodes. In this topology, each computer has its own control and decision-making power for communication priorities. The network provides high reliability since the failure of any single transmission line only affects communication between those two specific nodes, while all other connections remain operational. Fully-Interconnected Network (5 Nodes) ...
Read MoreWhat is MultiDrop Network Topology in Computer Network?
A MultiDrop Network Topology, also known as a broadcasting network, is a network configuration where multiple nodes share a single communication line or cable. Unlike a fully interconnected network that requires individual cables between all nodes, this topology uses one shared medium for all network communication. MultiDrop Network Topology A B C D Single Shared Communication Line Message ...
Read MoreWhat is Modem in Computer Network?
A modem (Modulation-Demodulation) is a crucial networking device that converts digital data signals into analog signals for transmission over analog communication lines, and vice versa. Modems bridge the gap between digital computers and analog telephone networks, enabling data communication over existing infrastructure. Modems can be installed within a computer in a compatible expansion slot or connected externally through serial ports. They serve as the interface between digital computing devices and analog transmission media. Types of Modems by Installation Internal Modems Internal modems are installed directly into a computer's expansion slot and do not require additional physical ...
Read MoreWhat are Network Connecting Devices?
Network connecting devices are essential hardware components that enable computers and other electronic devices to communicate and share resources like printers, files, and internet connections within a Local Area Network (LAN) or across different networks. These devices form the backbone of modern networking infrastructure, each serving specific functions in data transmission, routing, and protocol conversion. Let us examine the key network connecting devices and their roles. Network Interface Card (NIC) A Network Interface Card (NIC) is a hardware component that connects a computer to a network. The NIC is installed in an expansion slot within each computer ...
