1.缓冲区:
缓冲区是一个临时存储区域,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将用文档的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。
2.缓存:
高速缓存是计算机中较小且快速的内存组件,已插入CPU和主内存之间。为了使这种安排有效。高速缓存需要比主内存快得多。这种方法比使用快速存储设备实现整个主存储器更经济。
缓冲区和缓存之间的区别:
S.No. | BUFFER | CACHE |
---|---|---|
1. | Buffer is used to compensate for difference in speed between two processes that exchange or use data. | Cache is a smaller and fastest memory component in the computer. |
2. | It is mostly used for input/output processes. | It is used during reading and writing processes from the disk. |
3. | It is a normal storage area on ram for temporary storage. | It is a high-speed storage area for temporary storage. |
4. | It stores the original copy of data. | It stores the copy of original data. |
5. | It is always implemented in the main memory (RAM). | It is implemented in RAM as well as in Disk. |
6. | It is made from dynamic ram. | It is made from static ram. |
7. | It does not increase the accessing time. | It increase the accessing speed of CPU. |
8. | It can be used in keyboards to edit typing mistakes . | It does not posses such feature. |
