通过应用各种编码技术，字位的组合不但可以用来表示二进制数，还可以表示其他离散符号，比如十进制数字和字母表上的字母等。

By using various coding techniques, group of bits can be made to represent not only binary number but also other discrete symbols, such as decimal digits or letter of alphabet.

UTF - 8并没有迫使所有unicode字符挤入2字节、3字节或者4字节中，它允许对1字节(8位)到4字节进行编码。

Instead of forcing all Unicode characters into a 2 -, 3 -, or 4-byte straightjacket, UTF-8 admits 1-byte (8-bit) to 4-byte encodings.

相反，SPU可以以L1缓存的速度来访问本地存储器中的任何128位的字。

Instead, the SPU can access any 128-bit word in the local store at L1 cache speed.

And now that you have patterns of bits after bits after bits, and if you chunk them up into say, eight-unit quantities, now can you start storing words and sentences, and paragraphs.

你现在按照一定模式一位一位的进行排列，如果你组成块，8位一个单位，这时候我们就可以存储字和句子以及段落。

Is there a key word like int or char double with which you can represent a 1024-bit value?

有一个像int，char，double这样的关键字,用来表示一个1024位大小的数值呢？
