ASCII: American Standard Code for Information change; a system used to translate keyboard characters into bits. 美国信息交换标准码:把键盘字符转换成字节的系统。
This system contains all necessary control and data circuitry to interface with CRT, standard ASCII keyboard, matrix line printer, EPROM programmer, dual single side double density floppy disk drive, cassette tape recorder, etc. 系统具有各种必要的控制及数据线路,可以与CRT、标准键盘、针型行打、EPROM编程器、单面双密度软盘驱动器、盒式磁带录音机等相接。
In this article, It is introduced how a global ASCII Keyboard succession character entry speed equivalence matrix, which is relative to the code location, is figured out from more than two million experiment data. 本文从二百多万个实验数据中统计分析出通用小键盘连续击键键位相关速度当量矩阵。
