Question

How many pages a second can the disk transfer?

Answer 1

The Sloan Survey had a data transfer rate of 8 megabytes per second, and by calculating the number of pages based on the words that can be transferred, we find that the disk can transfer approximately 2949 pages per second.

Step-by-step explanation:

The question pertains to the data transfer rate of a disk, specifically in the context of how many pages it can transfer per second. To compute this, we will use the data transfer rate provided by the Sloan Survey. The Sloan Survey recorded data at a rate of 8 megabytes per second (8 MB/s). Since one MB is 1024 kilobytes (KB), and one KB is approximately equal to 180 English words, we can calculate the number of pages based on an average number of words per page.

First, we convert megabytes to kilobytes: 8 MB * 1024 = 8192 KB per second. If one KB is roughly 180 words, then 8192 KB is equivalent to 8192 KB * 180 words/KB = 1,474,560 words per second. Assuming an average full page contains about 500 words, we can then calculate the number of pages by dividing the words per second by the number of words per page: 1,474,560 words per second / 500 words/page = 2949.12 pages per second.

Therefore, the disk can transfer approximately 2949 pages each second, which illustrates the remarkable speed of modern data processing and the vast amounts of information that can be handled

Answer 2

The speed at which a disk can transfer pages per second depends on various factors, such as disk type, rotational speed, and data density, making it impossible to provide a specific answer without additional information.

Step-by-step explanation:

The transfer speed of a disk is a complex metric influenced by multiple variables. Factors include the type of disk (e.g., HDD or SSD), rotational speed (for HDDs), and data density. For instance, SSDs generally have faster data transfer rates compared to traditional HDDs due to their lack of moving parts. Rotational speed, measured in revolutions per minute (RPM), affects the performance of HDDs, with higher RPMs typically resulting in faster data access. Additionally, data density, or the amount of data stored in a given area, contributes to transfer speed.

In conclusion, without specifying the type of disk and its characteristics, it is not feasible to provide a precise value for the pages per second transfer rate.
