What is the difference between memory capacity and hard drive capacity?

The difference between memory capacity and hard disk capacity:

1. Different references

1. Hard disk capacity: in megabytes (MB) or Measured in gigabytes (GB), mainstream hard drive capacity ranges from 500G to 2TB. Factors that affect hard drive capacity include single-disc capacity and the number of discs.

2. Memory capacity: refers to the capacity of random access memory (RAM) and is a key parameter of the memory stick.

2. Different measurement standards

1. Hard drive capacity: Capacity is the most important parameter of the hard drive. Hard disk capacity = number of cylinders (indicating how many tracks there are on each disk surface, the general total is 1024) × number of heads (indicating the number of disk surfaces) × number of sectors (indicating how many sectors each track has, the general total is 64 ) × sector (basic unit of storage, generally 512B/4KB in size).

2. Memory capacity: The amount of memory is equal to the total capacity of all memory modules inserted in the motherboard memory slot. The upper limit of memory capacity is generally determined by the motherboard chipset and memory slot.

3. Different characteristics

1. Hard disk capacity: use byte (B, Byte), kilobyte (KB, KiloByte), megabyte (MB, MegaByte), Jizi Measured in knots (GB, Gigabyte).

2. Memory capacity: The larger the memory capacity, the better it is for the operation of the system.
