)是具备数据存储(datastorage)、修改功能，并实现对相关逻辑与数据的计算的现代化智能电子设备(intelligentelectronicequipment)作为集成网络、计算、媒体等技术为一体的电子设备，计算机技术是指计算机领域中所运用的技术方法和技术手段，或指其硬件技术(hardwaretechnology)、软件技术(softwaretechnology)及应用技术计算机技术具有明显的综合特性，它与电子工程(electronicengineering)x应用物理(appliedphysics)、机械工程(mechanicalengineering)、现代通信技术(moderncommunicationtechnology)和数学等紧密结合，发展很快。 CulturalBackgroundNEXTBACK CulturalBackgroundNEXTPREV.UP二、计算机技术的未来当前，世界各国都在积极研发超级计算机(supercomputer)，超级计算机是能够执行一般个人电脑无法处理的大资料量与高速运算的电脑。就超级计算的和普通计算机的组成而言，构成组件基本相同，但在性能和规模方面却有差异。超级计算机主要特点包含两个方面：极大的数据存储容量和极快速的数据处理(dataprocessing)速度，因此它可以在多种领域进行一些人们或者普通计算机无法进行的工作，可应用于医学制药(pharmaceutical)、先进制造(advancedmanufacture)、人工智能(artificialintelligence)等新兴领域。 CulturalBackgroundBACKPREV.三、中国面临的挑战从中国情况看，从事计算机软件开发的高端人才远远低于发达国家，半导体(semiconductor)生产技术也落后于欧美。美国从事计算机软件开发的人才达到180多万，印度达到90万，而中国从事计算机软件开发的人才不足40万。这就说明，中国计算机软件人才短缺，这将严重束缚中国IT行业的发展，特别是直接影响到中国经济的发展和社会的进步。现在，芯片(chip)行业已经成为了国家的战略产业。如果失去国外芯片的支持，几乎所有民用领域的电子产品升级都将受到严重制约，因此，从数学、计算机人才的培养，到材料领域的发展，都需要国家的大力支持。人工智能机器翻译AImachinetranslationWordstoKnowBACKaclassofthingsthathaveparticularfeaturesincommon种类，类别sort/sR:t/
