Motorola MVME167 64-W6972B01A

Description

如果计算机确实用二进制来说话，那么为什么那么多程序使用其他基数，比如10或16?

MVME167 基数10用于计算的唯一目的是使一个值可读。如果你有一个模拟温度传感器显示华氏温度，你愿意看到:10110011度吗?或者也许是B3学位?或者179度?我同意…最后一个对我来说更好。

以10为基数的问题是，计算机每次以4位为一批存储数值(或8位，或在大多数现代个人电脑中一直到64位)。如果我们检查4位单元，它可以容纳从0000到1111的任何值，等于15(稍后将详细介绍该计算)。所以有16个可能选项，或基数16.

为什么不用更常见的8位单位“字节”作为基数呢?我想这是可能的，MVME167 但是一个字节值可以是0到255之间的任何值，也就是256。这将导致基数为256的数字。计算机可以处理它，但是可怜的工程师有足够的时间翻译十六进制数，请，让我们保持合理。

If computers do use binary to speak, why do so many programs use other cardinals, such as 10 or 16?

The only purpose of MVME167 base 10 for calculation is to make a value readable. If you have an analog temperature sensor that displays Fahrenheit temperature, would you like to see: 10110011 degrees? Or perhaps it’s a B3 degree? Or 179 degrees? I agree… the last one is better for me.

The problem with a base of 10 is that computers store values in batches of 4 bits each time (or 8 bits, or all the way up to 64 bits in most modern personal computers). If we examine a 4-bit unit, it can accommodate any value from 0000 to 1111, equal to 15 (this calculation will be explained in detail later). So there are 16 possible options, or a base of 16

Why not use the more common 8-bit unit “byte” as the base? I think this is possible, MVME167, but a byte value can be any value between 0 and 255, which is 256. This will result in numbers with a base of 256. Computers can process it, but poor engineers have enough time to translate hexadecimal numbers. Please, let’s keep it reasonable.
