In the storage utilization context, a program that uses l0 kilobytes of storage for0.2 seconds during some phase of processing uses2"kilobyte seconds" of storage .

在用于存储器利用率时，如一程序在某一处理阶段使用10千字节存储器0.2秒，则称之为使用存储器2"千字节秒"。

The answer is forty. The scientists were Jerry Merryman, James Van Tassel and Jack Kilby. Their first device could add, subtract, multiply and divide. It had twelve bytes of memory -- close to nothing compared to today's powerful calculators. And it weighed more than a kilogram.

答案是40年以前，这三位科学家分别是Merryman，James Van Tassel和Jack Kilby，他们首次发明了可进行加，减，减和除的设备，它拥有十二字节存储器，与今天功能强大的计算器来说跟本就不算什么，并且它的重量有1公斤多。
