寄存器和缓冲区之间的区别

1.注册：
寄存器是处理器本身内置的最小的保留数据元素。这些是处理器可以直接访问的内存位置。它保存着32位到64位之间的少量数据，并且可以保存一条指令，一个存储地址或任何种类的数据，例如位序列或各个字符。

例如：累加器寄存器，程序计数器，指令寄存器，地址寄存器等。

2.缓冲区：
缓冲区是一个临时存储区，通常是内存中的一个块，在其中等待等待从输入设备或输出设备传输的项目被放置在其中。它主要用于输入/输出过程。例如，如果要打印较长的文档，则不希望CPU等待询问打印机“您准备好准备另一个段落了吗?”取而代之的是，CPU将用文档数据填充内存缓冲区，指示打印机打印缓冲区内容，然后再返回其其他业务。

寄存器和缓冲区之间的区别：

S.No.	Register	Buffer
1.	Registers is a small amount of fast storage element into the processor.	Buffer is used to compensate for difference in speed between two processes that exchange or use data.
2.	It is located on the CPU.	It is an area of RAM .
3.	It is used to store and retrieve information from them.	It is mostly used for input/output processes.
4.	It holds operands or instruction that CPU is currently processing.	It holds data for advance processing.
5.	It is used to store data temporarily for processing and transfer.	It is used to store data temporarily before using them.
6.	It increase the accessing speed of CPU.	It does not increase accessing time.
7.	Loop counters is example of register.	Streaming music or streaming video is example of buffer.
