以下是运行DOS系统中关于命令
MODE CON [ : ][RATE = r EDLAY = d ]
的一段英语解释。
Parameters
CON [ : ] Refers to the keyboard.
RAET = r
Specifies the rate at which a character is repeated on the screen when you hold down a key. Valid values are in the range 1 through 32. These values are equal to approximately 2 to 30 characters pre second, respectively. The default value is 20. If you set the rate, you must also set the delay.
DELAY = d
Specifies the amount of time that must elapse after you press and hold down a key before DOS starts to repeated the character. Valid values for d are 1, 2, 3, 4 (representing o.25, 0.5, 0.75, 1 second, respectively ). The default value is 2. If you set delay, you must also set the rate.
根据以上英语说明,该命令中,设置RATE参数的作用是 A ,设备DELAY参数的作用是 B 。命令中RATE和DELAY部分 C 的语法正确。系统默认的RATE和DELAY的值分别近似为 D 。为取得最快的速度,命令中RATE和DELAY设置应为 E 。
供选择的答案
A:①对击键速率的最高限制 ②屏幕闪烁速率
③屏光栅扫描的速率 ④按住键时连续显示该字符的速率
B:①从击键到显示该字符之间的时间
②两次击键之间的最短时间
③按住一键,该字符被多次重复显示时的间隔时间
④按住一键直到开始重复显示该字符之间的时间
C:①RATE = r DELAY = d ②RATE = 20
③RATE = 32 DELAY = 2 ④RATE = 25 DELAY = 0.5
D:①RATE :20字符/秒,DELAY :0.5秒
②RATE :20字符/秒,DELAY :2秒
③RATE :30字符/秒,DELAY :1秒
④RATE :2字符/秒,DELAY :2秒
E:①RATE = 32 DELAY = 4 ②RATE = 32 DELAY = 2
③RATE = 30 DELAY = 4 ④RATE = 1 DELAY = 0.25
