1. 缓存内存:
高速缓存是计算机中插入 CPU 和主内存之间的更小、速度更快的内存组件。为了使这种安排有效。缓存需要比主存快得多。这种方法比使用快速存储设备来实现整个主存储器更经济。

2. 注册:
寄存器是内置于处理器本身的最小保存数据元素。这些是处理器可以直接访问的内存位置。它保存大约 32 位到 64 位的少量数据,并且可以保存一条指令、一个存储地址或任何类型的数据,例如位序列或单个字符。

例如:累加器寄存器、程序计数器、指令寄存器、地址寄存器等。

高速缓存和寄存器的区别:

S.No. CACHE MEMORY REGISTER
1. Cache is a smaller and fastest memory component in the computer. Registers is a small amount of fast storage element into the processor.
2. Cache memory is exactly a memory unit. It is located on the CPU.
3. It is used during reading and writing processes from the disk. It is used to store and retrieve information from them.
4. It is a high-speed storage area for temporary storage. It is used to store data temporarily for processing and transfer.
5. It copied the recently used data into. It holds operands or instruction that CPU is currently processing.
6. It reduces the average memory access time. It reduces the time required to find the item stored in memory.
7. CPU accesses memory at the faster rate than register. CPU can operate on register contents at the rate of more than one operation in one clock cycle.
8. Dynamic Page Cache, Database Query Cache are example of cache. Loop counters is example of register.
