标题[问题] 硬碟容量计算
时间Thu Jan 3 18:48:36 2008
拜托板友帮我算一下罗
一直都搞不太懂的一题...
题目大意是看的懂,但是还是不会算
Consider a single-surface disk drive
having the following tracteristics.
Number of track per disk : 60
Number of sectors per track : 20
Bits per second transfer rate : 500,000
Revolutions per minute rotational speed : 360
Assume that byte is 8 bits
How many bytes is the nominal storage capacity of one disk?
(If no gaps or special formatting is assumed)
可不可以教一下这是要怎样计算? 还有答案 麻烦了~谢谢!

1F：推 forris:题目要问磁碟容量有多大,跟转速,位元传输速率无关 01/04 00:51
2F：→ forris:题目也没说硬碟里有几片磁碟,假设算一片,60*20*1=1200 byte 01/04 00:52
