一、第一台计算机 1946年2月15日,名叫“埃尼阿克”(ENIAC)的第一台通用电子数字积分计算机在美国宾夕法尼亚大学宣告研制成功。它一共使用了18000个电子管、1500个继电器和其它器件,总体积为90立方米。这个“庞然大物”重30吨,占地170平方米。 1984年,伴随着CPU的发展,苹果公司开发出第一台多媒体计算机,它带音频视频功能的显示器、声像输出输入装置、通信与控制端口、只读光盘驱动器、多媒体操作系统及应用软件。这台标准的多媒体电脑能够接受外部图像、声音及各种媒体信号,再进行加工处理。
The First Computer The first general electronic digital computer named ENIAC was announced on February 15, 1946 at the University of Pennsylvania in the United States. It uses a total of 18,000 tubes, 1,500 relays and other devices for a total volume of 90 cubic meters. This “behemoth ” weighs 30 tons, covers an area of 170 square meters. In 1984, with the development of the CPU, Apple developed the first multimedia computer, its display with audio and video capabilities, audio and video input and output devices, communication and control ports, CD-ROM drive, multimedia operating system and application software. This standard multimedia PC accepts external images, sounds and various media signals for further processing.
