Time taken to transfer one HTML file
View all questions of this test
= 
= 0.8 ms
= 0.8 msAvg. rotational latency = ½ x 6ms = 3 ms
[10,000 RPM ⇒1 rotation = 6 ms]
∴ Avg time to read an HTML file
= 0.8 + 3 ms + 8 ms + 2 ms = 13.8 ms
Time taken to read one HTML file = 13.8ms
1 sec ⇒ 1 sec 
= 72 files
= 72 files∴ 72 HTML files can read per second.

Throughput to transfer HTML files:
To find the throughput to transfer HTML files, we need to consider the transfer speed, disk characteristics, and the system's maximum bandwidth.
Given:
Transfer speed = 107 bytes/sec
RPM = 10,000
Average seek time = 8ms
Overhead per disk operation = 2ms
System bus maximum bandwidth = 133 Megabytes/sec
Network connection bandwidth = 107 bytes/sec
HTML file size = 8000 bytes
Calculating throughput:
1. Calculate the disk transfer rate:
Disk transfer rate = (RPM / 60) * (bytes per track / average seek time)
We know that the disk transfer rate = 107 bytes/sec, and average seek time = 8ms.
Converting average seek time to seconds: 8ms = 0.008 seconds.
Therefore, (RPM / 60) * (bytes per track / 0.008) = 107 bytes/sec
Simplifying, bytes per track = (107 * 0.008 * 60) / RPM
2. Calculate the number of HTML files that can be transferred per second:
Number of HTML files per second = (disk transfer rate - overhead per disk operation) / HTML file size
We know that the overhead per disk operation = 2ms, which is equivalent to 0.002 seconds.
Therefore, (disk transfer rate - 0.002) / 8000 = throughput in HTML files per second
3. Calculate the maximum throughput:
Since the system bus has a maximum bandwidth of 133 Megabytes/sec, we need to convert it to bytes/sec:
133 Megabytes/sec = 133 * 1024 * 1024 bytes/sec
Now, we can substitute the calculated disk transfer rate and HTML file size into the formula:
(disk transfer rate - 0.002) / 8000 = 133 * 1024 * 1024
Solving this equation will give us the maximum throughput in HTML files per second.
Answer:
The correct answer is option (a) 72.
To find the throughput to transfer HTML files, we need to consider the transfer speed, disk characteristics, and the system's maximum bandwidth.
Given:
Transfer speed = 107 bytes/sec
RPM = 10,000
Average seek time = 8ms
Overhead per disk operation = 2ms
System bus maximum bandwidth = 133 Megabytes/sec
Network connection bandwidth = 107 bytes/sec
HTML file size = 8000 bytes
Calculating throughput:
1. Calculate the disk transfer rate:
Disk transfer rate = (RPM / 60) * (bytes per track / average seek time)
We know that the disk transfer rate = 107 bytes/sec, and average seek time = 8ms.
Converting average seek time to seconds: 8ms = 0.008 seconds.
Therefore, (RPM / 60) * (bytes per track / 0.008) = 107 bytes/sec
Simplifying, bytes per track = (107 * 0.008 * 60) / RPM
2. Calculate the number of HTML files that can be transferred per second:
Number of HTML files per second = (disk transfer rate - overhead per disk operation) / HTML file size
We know that the overhead per disk operation = 2ms, which is equivalent to 0.002 seconds.
Therefore, (disk transfer rate - 0.002) / 8000 = throughput in HTML files per second
3. Calculate the maximum throughput:
Since the system bus has a maximum bandwidth of 133 Megabytes/sec, we need to convert it to bytes/sec:
133 Megabytes/sec = 133 * 1024 * 1024 bytes/sec
Now, we can substitute the calculated disk transfer rate and HTML file size into the formula:
(disk transfer rate - 0.002) / 8000 = 133 * 1024 * 1024
Solving this equation will give us the maximum throughput in HTML files per second.
Answer:
The correct answer is option (a) 72.
