课程名称：计算机网络（印地语） 课程概述： 数据通信指的是在两个或多个计算机之间传输数字数据，而计算机网络或数据网络是一个电信网络，允许计算机之间交换数据。网络计算设备的物理连接可以通过有线介质或无线介质建立。最著名的计算机网络是互联网。本课程将教授数据通信和计算机网络（DCN）的基础知识，并深入探讨与数据通信和计算机网络相关的各种高级概念。 学习数据通信与计算机网络的理由： 1. 网络基础理解：相互连接的计算机和计算机外设（如打印机）形成了计算机网络。计算机之间的这种互联有助于信息的共享，连接可以通过有线或无线介质实现。 2. 网络工程：网络工程是一项复杂的任务，涉及软件、固件、芯片级工程、硬件和电信号工程。为简化网络工程，整个网络概念被分为多个层级。每一层负责特定任务，与其他层相互独立，但整体上几乎所有的网络任务都依赖于这些层级。层级之间共享数据，并仅依赖彼此以获取输入和发送输出。 3. 互联网：互联网络是多个网络的网络，简称为互联网。它是地球上存在的最大网络，广泛连接所有广域网（WAN）以及局域网（LAN）和家庭网络。互联网使用TCP/IP协议集，以IP作为其地址协议。当前，互联网主要使用IPv4，但由于地址空间的匮乏，正逐步向IPv6迁移。互联网使用户能够共享和访问全球大量信息，使用的服务包括WWW、FTP、电子邮件、音视频流等。互联网的运行主要是基于客户端-服务器模型，并通过光纤建立了高速骨干网，跨越各大洲的光缆被称为海底通信电缆。 4. 通信与计算机网络的应用：计算机系统和外设通过网络连接，提供众多优势，包括： - 资源共享，如打印机和存储设备 - 信息交换，通过电子邮件和FTP - 通过网络或互联网共享信息 - 与其他用户互动，使用动态网页 - IP电话 - 视频会议 - 并行计算 - 即时消息 本课程适合希望深入了解计算机网络和数据通信原理的学习者。
Data communications refers to the transmission of this digital data between two or more computers and a computer network or data network is a telecommunications network that allows computers to exchange data. The physical connection between networked computing devices is established using either cable media or wireless media. The best-known computer network is the Internet.This tutorial should teach you basics of Data Communication and Computer Network (DCN) and will also take you through various advance concepts related to Data Communication and Computer Network.Why to Learn Data Communication & Computer Network?Network Basic UnderstandingA system of interconnected computers and computerized peripherals such as printers is called computer network. This interconnection among computers facilitates information sharing among them. Computers may connect to each other by either wired or wireless media.Network EngineeringNetworking engineering is a complicated task, which involves software, firmware, chip level engineering, hardware, and electric pulses. To ease network engineering, the whole networking concept is divided into multiple layers. Each layer is involved in some particular task and is independent of all other layers. But as a whole, almost all networking tasks depend on all of these layers. Layers share data between them and they depend on each other only to take input and send output.InternetA network of networks is called an internetwork, or simply the internet. It is the largest network in existence on this planet.The internet hugely connects all WANs and it can have connection to LANs and Home networks. Internet uses TCP/IP protocol suite and uses IP as its addressing protocol. Present day, Internet is widely implemented using IPv4. Because of shortage of address spaces, it is gradually migrating from IPv4 to IPv6.Internet enables its users to share and access enormous amount of information worldwide. It uses WWW, FTP, email services, audio and video streaming etc. At huge level, internet works on Client-Server model.Internet uses very high speed backbone of fiber optics. To inter-connect various continents, fibers are laid under sea known to us as submarine communication cable.Applications of Communication & Computer NetworkComputer systems and peripherals are connected to form a network.They provide numerous advantages:Resource sharing such as printers and storage devicesExchange of information by means of e-Mails and FTPInformation sharing by using Web or InternetInteraction with other users using dynamic web pagesIP phonesVideo conferencesParallel computingInstant messaging
