Unfortunately the 32-bit address space is pretty tight, leaving little room for randomization andhampering its effectiveness.
不幸的是，32位地址空间非常吃紧，限制了随机分配地址的范围和效率（hamperingits effectiveness）。

即使目标处理器(PPE)拥有64位的本地地址空间，spu_mfcdma32函数也会使用一个32位的值。
Subnet mask is a 32-bit address, IP address used to shield part of the difference between a network address and host address.
子网掩码是一个32位地址，用于屏蔽ip地址的一部分以区别网络地址和主机地址。
Unfortunately the 32-bit address space is pretty tight, leaving little room for randomization and hampering its effectiveness.
不幸的是，32位地址空间是非常紧张，留下一点空间随机化，妨碍了其有效性。
Of the disadvantages, a 32-bit program must be cognizant of the segmented architecture to take full advantage of the 32-bit address space.
缺点是，32位的程序必须认识这种分段体系结构，才能充分利用32位地址空间。
The spu_mfcdma32() function allows DMA from a 32-bit subset of the PPE's theoretical 64-bit address space which is plenty for our purposes.
spu_mfcdma32()函数允许从PPE的（理论上）64位地址空间中的32 位子集中使用DMA 方式获取数据，这对于我们的目的来说已经足够了。
Because channels are written using a register's preferred word-sized slot, the 64-bit address already has the high-order bits in the preferred slot.
由于信道是通过寄存器单字大小的首选槽写入的，所以64位地址在首选槽内已经有了高阶位。
It permits the use of 64 bit data source drivers and can leverage the 64 bit address space for query processing, metadata caching and data caching.
它允许使用64位数据源驱动程序，且可以利用64位满足查询处理、元数据缓存和数据缓存的空间。
Although the processors can store 32-bit address values, the top eight bits (actually more than eight, on the 68008) are not wired to anything, and have no effect.
尽管处理器可以存储32位地址值，但是高8位(实际上在68008中多于8位)并没有被使用，因此这样做也不会产生什么影响。
"My only defense is that decision was made in 1977, at a time when it was uncertain if the Internet would work," Cerf said recently, adding that a "128-bit address space seemed excessive back then."
Cerf最近补充道，我唯一保守的就是在1977年做的决定，那个时候还不知道互联网能不能工作，128位地址在那个时候看起来没有必要。
The address of a socket in the Internet domain consists of the Internet address of the host machine (every computer on the Internet has a unique 32 bit address, often referred to as its IP address).
互联网模式的地址格式是一个机器地址（一般是使用32字节代表的IP地址）。
Most modern non-64-bit systems have the ability to create an address space of 36 bits, yielding 64 GB of addressable memory.
大多数现代的非 64位系统都能够创建36位的地址空间，从而产生 64GB 的可寻址内存。
An IP address matches a netmask based on precise bit pattern matching rules (beyond the scope of this article).
基于精确的位模式匹配规则(超出本文范围)，IP地址与网络掩码相匹配。
Other than regular web documents, Spoke also scans social networks and even the whois information of domain names to find any bit of information associated with an email address.
除了普通的网络档案外，Spoke还扫描了社交网络甚至是域名的whois信息以查找与电邮地址相关的任何一点信息。
A 64-bit environment and the ability to address more than 4 GB of memory can greatly enhance the scalability and performance of databases.
位环境以及解决大于4GB内存的能力，可以大大增强数据库的可伸缩性和性能。
A 64-bit runtime USES 64-bit Pointers (native address references), so the same Java object on 64-bit takes up more space than an object containing the same data on 32-bit.
位运行时使用64位指针(本机地址引用)，因此64位运行时中的相同对象会占用更多的空间。
This is so that the address transfer is stored the same way whether it is compiled in 32-bit mode or 64-bit mode.
这是因为传输的地址被按同样的方式存储，而不管它是被按32 位模式还是 64位模式编译的。
If each address references a byte of storage, a 16-bit physical address would allow a processor to address 64kb of memory.
如果每个地址引用一个存储字节，那么一个16位物理地址将允许处理器寻址64KB内存。
The Internet Protocol defines an IP address as a 32-bit number.
互联网协议将IP地址定义为一个32位的编号。
Figure 6 shows the 32-bit memory address space for a DB2 agent process.
图6展示了用于一个DB 2代理进程的32位内存地址空间。
Exhausting the address space typically only happens with 32-bit processes - because the maximum 4gb of address space is easy to allocate.
耗尽地址空间通常只发生在32位进程中—因为可以轻松地分配最大4gb地址空间。
On 32-bit systems, the default address-space model is that it USES a single segment for user and stack data with a maximum aggregate size close to 256 MB.
在32位系统上，默认的地址空间模型是对于用户和堆栈数据使用单一数据段，最大总大小接近256MB。
