Teletype Network，通常称为Telnet，是一种网络协议，早于当前使用的传输控制协议^{(Transmission Control Protocols)}( TCP ) 和Internet 协议^{(Internet Protocols)}(IP)。Telnet早在 1969 年就开发出来了，它使用一个简单的命令行界面^{( simple command-line interface)}，主要用于在两个不同系统之间建立远程连接并在它们之间进行通信。那么，如何在 Windows Server 2019 或 2016 上启用 Telnet？^{(how to enable Telnet on Windows Server 2019 or 2016?)}Telnet网络协议由两种不同的服务组成：Telnet Client^{(Telnet Client)}和Telnet Server. 寻求控制远程系统或服务器的用户应该运行Telnet客户端，而其他系统运行Telnet服务器。我们为您提供了一份完美的指南，将帮助您了解如何在Windows 7/10Telnet。

如何在 Windows 7 或 10 中启用 Telnet^{(How to Enable Telnet in Windows 7 or 10)}

由于Telnet网络协议是在 Internet 形成的年代开发的，它缺乏任何形式的加密^{(it lacks any form of encryption)}，并且 Telnet 服务器和客户端之间的命令以纯文本形式交换。在 1990 年代，当互联网和计算机可供更广泛的受众使用时，对通信安全的担忧开始增加。这些担忧导致Telnet被安全外壳协议^{(Secure Shell Protocols)}( SSH ) 所取代，该协议在传输之前加密数据并通过证书对连接进行身份验证。然而，Telnet 协议^{(Telnet protocols)}还没有完全消亡和埋葬，它们仍然被用于：

• 发送命令和远程管理服务器以运行程序、访问文件和删除数据。
• 管理和配置新的网络设备，例如路由器和交换机。
• 测试 TCP 连接性。
• 检查端口状态。
• 连接射频终端^{(RF Terminals)}、条码^(Barcode)扫描仪和类似的数据采集设备。

^(Data)Telnet以简单文本格式传输数据意味着更快的速度^{(faster speed)}和简单的设置^{(easy setup)}过程。

所有Windows版本都预装了Telnet 客户端；^{(Telnet Client)}虽然，在Windows 10中，客户端默认禁用^{(disabled by default)}，需要手动启用。另请阅读适用于 Windows 的 30 大最佳 IRC 客户端^{(op 30 Best IRC clients for Windows)}。Telnet Windows Server 2019/2016或 Windows 7/10只有两种方法。

How to Enable Telnet in Windows 10

Teletype Network, more commonly known as Telnet, is a network protocol that predates the currently used Transmission Control Protocols (TCP) and Internet Protocols (IP). Developed as early as 1969, Telnet uses a simple command-line interface which is predominantly, used to establish a remote connection between two different systems and communicate between them. So, how to enable Telnet on Windows Server 2019 or 2016? The Telnet network protocol consists of two different services: Telnet Client & Telnet Server. Users seeking to control a remote system or server should be running the Telnet client while the other system runs a Telnet server. We bring to you a perfect guide that will help learn how to enable Telnet in Windows 7/10.

How to Enable Telnet in Windows 7 or 10

Since Telnet network protocols were developed in the formative years of the internet, it lacks any form of encryption, and commands between a telnet server and client are exchanged in plain text. In the 1990s, when the internet and computers were becoming available to a much larger audience, concerns over communication security started growing. These concerns saw Telnet being replaced by the Secure Shell Protocols (SSH) which encrypted data before transmitting and authenticated connections by the means of certificates. However, Telnet protocols are not at all, dead and buried yet, they are still being used to:

• send commands & remotely manage the server to run a program, access files & delete data.
• manage & configure new network devices such as routers & switches.
• test TCP connectivity.
• check port status.
• connect RF Terminals, Barcode scanners and similar data collection devices.

Data transfer in simple text format by Telnet implies faster speed and easy setup process.

All Windows versions have the Telnet Client pre-installed; although, in Windows 10, the client is disabled by default and requires manual enabling. Also read Top 30 Best IRC clients for Windows. There are only two ways on how to enable Telnet Windows Server 2019/2016 or Windows 7/10.
