Email security may be referred to by different terms; for example, some vendors call it secure email gateway. It is a network-based software system that protects users against phishing, spam, malicious links, inappropriate images or content, and malware. The product can be provided as software, licensed to be run on customer-standard off-the-shelf servers, or included as complete hardware and software solutions.

A content delivery network is platform, which is highly distributed by server to minimize delays and loss time in web page and content loading by minimizing physical distance between the user and server. This helps users to view and show high-quality content and web page without delay in loading. Without using content delivery network server, the local server must respond to each and every single user request ticket. This will create significant traffic at the origin and increase chances of server failure; however, content delivery network carries significant protection for internet traffic.

CDSS systems have revolutionized clinical decision-making. The adoption of CDSS has been shown to reduce the chances of error and cost. The adoption rate of CDSS has been steadily increasing across regions and is expected to increase further, driven by the advent of new cutting-edge analytical technology and data security measures. The following figure illustrates the market share of key companies in the global CDSS market in 2019:

2020 年通信行业实现营业收入 7,210 亿元，同比增长 3.27%。一季度行业业绩增速明显改善。考虑到 2021 年运营商 5G 建投的持续高投入，主设备、天 线射频、光模块等板块有望获益。建议关注 5G 建设持续跟进、具备 技术优势的中兴通讯、天孚通信。全年业绩表现上，2020 年业绩增速 较佳的板块有光模块、IDC、云办公、北斗等。随着疫情趋于可控， 全球云市场及云资本开支有望进一步扩张，5G 终端种类有望持续增 加，5G 应用有望显著拓展深化，为细分行业持续增长提供保障。

受益于宏观经济的恢复，以及疫情后全球数字化、云化进程加速，FAAMG 一 季度主要业绩显著好于此前市场预期。展望 2021，我们预计科技巨头当前业绩 高增速有望继续延续，但考虑到去年基数效应，以及成本&费用支出的快速恢 复，盈利同比增速料将逐季放缓，同时亦需关注美债利率波动、芯片短缺、政 策监管等潜在风险项。目前北美云巨头资本开支已进入复苏通道，下半年表现 料将显著好于上半年。

行业整体平稳增长，Q1 收入明显反弹。盈利承压趋缓，经营性现金流不断向好。金融科技增速领跑，工业互联网、云计算景气依旧。智能汽车量产加速，景气度有望继续抬升。存量与增量并举，金融科技迎确定性机遇。 政策叠加趋势，工业+云需求潜力可期。

围绕数据的价值挖掘全过程，提供工具和基础设施的软硬件、系统解决方案及相关服务产业，即为 战略科技产业。 数据已成为信息化时代核心战略资源。信息化时代，技术创新、政策演进、企业需求和人才红利推动数据成为核心战略资源。围绕数据价值挖掘打造战略科技产业。在应用场景中把握战略科技投资价值。

板块整体业绩：业绩实现同比增长，“缺货涨价”行情延续。虽然受到新冠 疫情和中美贸易摩擦等因素影响，国内电子行业 2020 年、2021 年第一季度营收、 归母净利润仍实现同比增长，且盈利能力有所提升，主要驱动力为疫情影响下远 程办公刺激 PC&服务器需求、苹果引领新一轮 5G 换机周期、国内集成电路国产 替代加速和汽车电子开始放量等。
