(CAD/CAM)计算机辅助设计和计算机辅助制造方面的许多专家预言,技术上的快速变革将继续提高绘图机和数字化设备的速度,这两种设备是计算机外围设备武器库中的基本武器。把信息输入计算机并将该数据的硬拷贝画出来的装置叫计算机的外围设备。更确切地说它们是计算机的必需品,没有它们这些计算机辅助设计的软件和硬件就失去了实用价值。工程师们需要快速、可靠和相对低成本的计算机外围设备,新技术的发展有助于生产厂家进行技术改造来实现这一目标。例如,利用软件驱动器可以不必首先转换矢量格式,而直接输出光栅数据。而转换矢量格式是一项费时费硬件的事。
(CAD / CAM) Many experts in computer-aided design and computer-aided manufacturing predict that rapid technological changes will continue to increase the speed of plotters and digitizers, the two basic weapons in arsenal of computer peripherals. The device that enters information into a computer and draws a hard copy of the data is called the computer’s peripherals. Rather, they are a necessity of computers that have lost their usefulness without these computer-aided design of software and hardware. Engineers need fast, reliable and relatively low-cost computer peripherals, and the development of new technologies helps manufacturers make the technical changes to achieve this goal. For example, raster data can be output directly without having to first convert the vector format using a software driver. Converting vector formats is a time-consuming piece of hardware.
