Learn for Computer Networking Data Communication

This application is designed to know about basic concept of Networking. A computer network is a group of computer systems and other computing hardware devices that are linked together through communication channels.

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.

-> And You can get more explain about the operating system networking.

Computer networks can be discriminated into various types such as Client-Server, peer-to-peer or hybrid, depending upon its architecture. There can be one or more systems acting as Server. Other being Client, requests the Server to serve requests.Server takes and processes request on behalf of Clients.Two systems can be connected Point-to-Point, or in back-to-back fashion. They both reside at the same level and called peers. There can be hybrid network which involves network architecture of both the above types.

There are many other devices on modern computer data networks, such as Firewalls, Proxy Servers, Intrusion Detection Systems, Intrusion Prevention Systems to name just a few.

There is a lot of varied network equipment that can be used around the home or office and hopefully this article has cleared up some of the confusion about the technologies available. If you are unsure of your requirements then a simple search will bring millions of results enabling research and advice from other users who have created their own network.

此应用程序的目的是了解网络的基本概念。计算机网络是一组计算机系统和通过通信信道连接在一起的其它计算硬件设备。

数据通信是指两个或多个计算机和计算机网络或数据网络是电信网络，其允许计算机交换数据之间的这种数字数据的传输。联网计算设备之间的物理连接是使用电缆的任何介质或无线介质建立的。最著名的计算机网络是互联网。

这个应用程序的功能计算机网络指南分类：

- 网络基础

- 物理层

- 数据链接层

- 传输层

- 应用层

- >你可以得到更多有关操作系统的联网解释。

计算机网络可以区分为各种类型，诸如客户端 - 服务器，对等网络或混合，这取决于其结构。可以有作为服务器的一个或多个系统。另一种是客户端，要求服务器提供requests.Server需要和工艺代表Clients.Two系统可以连接点至点，或背到背的时尚要求。他们都住在同一水平，并呼吁同行。可以存在将同时涉及上述类型的网络架构混合网络。

有现代计算机数据网络，如防火墙，代理服务器，入侵检测系统，入侵防御系统等诸多设备，仅举几例。

有很多多变的网络设备，可以在家庭或办公室中使用，希望这篇文章已经清除了一些有关可用技术的混乱。如果你不确定你的要求，那么一个简单的搜索将带来数以百万计的结果使得从谁创造了他们自己的网络的其他用户的研究和建议。
