The fastest speed in the computer memory hierarchy is the Register in CPU. Here's why:

1. Disk Cache: This is a dedicated cache memory used to speed up access to data on a disk. However, it is slower than other types of caches because it involves reading data from a physical disk.

2. Cache: This is a smaller, faster memory which stores copies of the data from the most frequently used main memory locations. While faster than the disk cache, it is still slower than the register in the CPU.

3. Register in CPU: This is the fastest type of memory in a computer. The CPU register holds data that are currently being processed. Since it's located inside the CPU itself, data doesn't have to travel, allowing for faster data access and processing.

4. Main Memory: This is the 'working' memory of the computer. It is slower than the cache and CPU register because it is further away from the CPU, and thus takes longer for data to travel back and forth.

So, in the hierarchy of speed, it goes: Register in CPU Cache Main Memory Disk Cache.
