The lexicon comprises two distinct categories: Term Lexicon and Hotword Lexicon The Term Lexicon facilitates translation rules for specific vocabulary (such as product names, ambiguous terms, and loanwords) in cross-lingual translation scenarios, ensuring translation accuracy Meanwhile, the Hotword Lexicon significantly enhances speech recognition accuracy for proprietary terms (including brands and technical terminology) by incorporating weighted entries When encountering homophones with identical tones, the system prioritizes matches with higher-weighted hotwords, thereby enabling more precise and professional live subtitle generationPoints of Attention

本文将从云服务器实例功能特性、常见业务场景、注意事项及最佳实践等方面介绍如何进行实例选型，帮助您了解应如何结合实际业务场景选购云服务器。实例选型分析过程如下图所示： 

什么是云服务器 CVM ？云服务器 CVM（Cloud Virtual Machine，CVM）是腾讯云提供的可扩展的计算服务，无需购买昂贵的物理硬件，即可在几分钟内获得安全可靠的虚拟计算环境。CVM 免去了传统服务器需要预估容量和前期投入的麻烦，让您能够按需启动任意数量的实例并快速上线业务。同时，您可以随时自定义并调整 CPU、内存、硬盘、网络、安全等全部资源，真正做到即用即付、弹性伸缩。

Fundamental information Product Abbreviation in CAM Console Authorization by Tag Authorization Granularity IP Restriction Domain domain Supported not supported Operation level Partially supported Note The authorization granularity of cloud products is divided into three levels: service level, operation level, and resource level, based on the degree of granularity Service level: It defines whether a user has the permission to access the service as a whole A user can have either full access or no access to the service For the authorization granularity of cloud products at service level, the authorization of specific APIs are not supported Operation level: It defines whether a user has the permission to call a specific API of the service For example, granting an account read-only access to the CVM service is an authorization at the operation level Resource level: It is the finest authorization granularity which defines whether a user has the permission to access specific resources For example, granting an account readwrite access to a specific CVM instance is an authorization at the resource l

CVM 价格参考本文汇集目前腾讯云所在区域的各类型云服务器的价格供参考。实际成交价格以最后下单为准。以区域字母顺序排列，方便查询。表格中实例规格可参考云服务器实例规格介绍获得更多信息。

本文主要介绍可能引起云服务器网络访问丢包问题的主要原因，及对应排查、解决方法。可能原因引起云服务器网络访问丢包问题的可能原因如下：触发限速导致 TCP 丢包

对云服务器进行关机，重启的操作时，有非常少的概率会出现关机失败或者重启失败的情况。如果您遇到此类情况，可以对云服务器进行如下排查和处理。可能原因CPU 或者内存使用率过高。Linux 操作系统的云服务器未安装 ACPI 管理程序。

操作场景在创建云服务器时，您可以通过指定自定义数据，进行配置实例。当云服务器首次启动时，自定义数据将以文本的方式传递到云服务器中，并执行该文本。如果您一次购买多台云服务器，自定义数据会在所有的云服务器首次启动时运行该文本。
