ZigBee is based on IEEE's 802.15.4 personal-area network standard and is widely considered an alternative to Wi-Fi and Bluetooth for some applications including low-powered devices, that don't require a lot of bandwidth such as smart home sensors. ZigBee is considered a superior technology for smart homes since it operates in a mesh network. It supports up to 65,000 nodes on a single network. While there are limits to interoperability due to multiple application profiles, such as Home Automation and Smart Energy, Zigbee's device interoperability is still a very useful feature. Keeping this in mind, The ZigBee Alliance announced the ‘All Hubs Initiative’ in May 2019, to make smart home and IoT products easier to develop, deploy, and sell across ecosystems. It would strengthen interoperability, reliability, and security Across the IoT.

Drive by wire system is also known as the X by wire and is semi-automatic, computer-controlled technology, which is used in autonomous vehicles. This system is used to control the vehicular systems such as handling, braking, steering, and other vehicle motor functions. In addition, electronic components such as sensors and actuators are used to control the vehicular functions and eliminate the need to use traditional mechanical linkages. The drive by wire market is anticipated to witness significant growth over the years, owing to rise in development of autonomous vehicles and development of connected infrastructure. The global drive by wire market is segmented into application, vehicle type, component and region. Depending on application, the market is divided into throttle by wire, shift by wire, brake by wire, park by wire, and steer by wire. On the basis of vehicle type, it is categorized into passenger car, commercial vehicle, electric vehicle, and Off-highway Vehicles. Components are categorized as Actuator, Electronic Control Unit (ECU), Engine Control Module (ECM), Electronic Throttle Control Module (ETCM), Electronic Transmission Control Unit (ETCU), Feedback Motor, Parking Pawl, Sensors, and Others. By region, the market is analyzed across North America, Europe, Asia-Pacific, and LAMEA.

Clickstream analytics is a set of processes that collect, analyze, and provide visualized results of aggregated clickstream data. Clickstream data is information trail that a web surfing user leaves behind while visiting a website. The clickstream data is typically captured in semi-structured website log files. These website log files contain data elements such as a date and time stamp, the visitor’s IP address, the URLs of the pages visited, and a user ID that uniquely identifies the user. Thus, businesses that operate through online applications benefit from clickstream analytics by analyzing the clickstream data. Therefore, the market is expected to grow at a significant rate during the forecast period, owing to aforementioned factors. Furthermore, rise in elusive clickstream data due to diversified platforms such as Facebook, Twitter, Snapchat, and Google fuels the demand for clickstream analytics. The clickstream analytics have ability to refine data by processing, cleaning, and transforming the raw data into convenient structure that makes analysis of data easy and more accurate.

A data lake is a place where every type of data is stored in its native format, with no fixed limits on account size or file. It is basically a storage repository, which offers high data quantity to increase analytical performance and native integration. A data lake is a powerful form of data architecture that leverages the economics of Big Data to its benefit. These solutions are comparatively 20-50% cheaper to store, manage, and analyze data, when compared to the traditional data warehouse technologies. Typically, data lakes are being built using Hadoop, followed by the deployment of a variety of storage and processing tools, to extract value quickly and help the organizations in making informed choices.

在教育领域， 受制于教育“反人性” 、 需要“仪式感”“场景感”“个性化” 等特质， 互联网对教育的重构一直很缓
慢， 但随着宽带扩容、 硬件升级及ABCDE（ AI、 Block Chain、 Cloud Computing、 Data Tech、 Edge Computing） 技术发展， 互联网在教育领域渗透程度正不断加深， 逐步从外围工具层面渗透到核心的教学教辅和教学认知思考层面。 直播+在线教育平台独有模块（ 如举手、 在线课件分享、 在线测评反馈） 提升了在线课堂的体验， 加速了在线教育或线上线下融合模式在教育领域的渗透， COVID-19新冠疫情更是强制实行了一次全体师生的在线教育实践。 随着在线教育的发展，互联网巨头也开始加入到教培蛋糕的瓜分行列， 互联网惯有的流量采买逻辑也让在线教育流量越买越贵， 入局者的不断增多让注意力越来越稀缺， 高额的流量采买费用导致成本结构恶化， 在线教育公司普遍亏损 .

Q1三大电商平台以及线上布局优异的品牌企业业绩表现相对稳健，疫情后在品牌与平台的协力推动下，持续的电商促销活动也推动了消费复苏。今年“618”大促在促销方式及力度上远超往年，有望加速助力刺激消费复苏。

2019年是互联网诞生50周年、万维网诞生30周年，也是我国全功能接入国际互联网25周年。我国互联网由最初的学习美国，到后来的本土创新，形成中国特色和中国模式，走在了世界前列。并与美国互联网几乎保持着相同的节奏，实现了同步发展，被誉为互联网的“双子星”。然而，近两年中美互联网反而有差距拉大的趋势，需引起我们的高度重视。
