Answer:
The capacity of the disk is "40 GB".
Explanation:
Given value:
[tex]\to \text{cylinder}= 10,000\\\\\to \frac{sector}{track} = 400\\\\\to \frac{bytes}{sector} = 512\\[/tex]
[tex]\text{Calculating the size of track} = \frac{bytes}{sector} \times \frac{sector}{track}[/tex]
[tex]= 512 \times 400 \\\\ = 204,800 \ \ Or \ \ 200 \ K[/tex]
[tex]\text{Calculating the size of surface} = \frac{byte}{track} \times \ cylinder[/tex]
[tex]= 2000 \ K \times 10,000 \\\\ = 20, 000,000 \ K[/tex]
[tex]\text{Calculating the capacity of a disk} = \frac{byte}{surface} \times \frac{surface}{disk}[/tex]
[tex]= 20, 000,000 \ K \times 2 \\\\ = 40, 000,000 \ K \\\\= 40 \ GB[/tex]
Cache memory is often used to speed up the runtime. It will enable us to improve performance unless we can store information, that is retrieved constantly in memory space.
- Hit Cache: when the Processor relates to representing database data, Cache Hit results.
- Miss Cache: when this Processor responds to a non-present cache data, this will trigger its miss of cache.
- It doesn't have to retrieve the Main Memory through secondary storage.
