Calculate the access time for a disk having the size of 512 byte/sector and the seek time of 12ms. The rotational rate is 5700 RPM. The data transfer rate is 3MB/sec, and the the controller overhead is 1ms, you may even assume that there is no service time for the access.
A disk drive has 1000 cylinders, 8 tracks per cylinder, 32 sectors per track, and 512 bytes per sector. The rotation time is 4ms. The read/write head takes 10ms to move between adjacent cylinders. A data file contains 200KB of data stored consecutively. What is the maximum seek time if the average time needed to read the data is 170ms?
What exactly does the term "short stroking" relate to, and how does it affect the price that is paid per gigabyte for solid-state drives (SSDs)? Short stroking refers to the process of writing data in a sequence that is shorter than the data that is being read.
A manufacture wishes to design a hard disk with a capacity of 60 GB or more (using thestandard definition of 1GB = 230 bytes). If the technology used to manufacture thedisks allows 512-bytes sectors, 1024 sector/track, and 60% tracks/ platter, how manyplatters are required?

Computer Science Draw a sector representing one platter surface of a hard disk with sixteen sectors. On your drawing show a track, the sectors, and a single block. Place a magnetic head somewhere on your drawing. Show on your drawing the seek time, latency time, and read time for the block that you drew on the disk.
The outputs of four registers, A, B, C, D, H, L are connected through 8:1 line multiplexer to the input of a fifth register, X. Each register is 16 bits long. The required transfers are dictated by four timing variables, T0 through T3 as follows: T0 : X←A T1 : X←B T2 : X←C T3 : X←D The timing variables are mutually exclusive, which means that only one variable is equal to 1 at any given time, while the others are equal to 0. Draw a block diagram showing the hardware implementation of the register transfers. Include the connections necessary from the four timing variables to the selection inputs of the multiplexers and to the load input of register X.

Data bit recording in magnetic discs is based on which property of magnetic material? Please explain. Is it a problem if this feature is too large? Why is that? A disk drive is provided that can write data at a flux change rate of 6 million per second. Calculate the maximum number of data bytes that can be stored in one ring of the disk when the disk is rotated at 6000 rpm. Indicate how the increase in disk rotation speed affects the data storage capacity.
Q1- Design and implement an Heart Pulse and Temperature Monitoring system using an 8051 as shown in Figure 1. -The 8051 will continuously monitor the 8-bit integer outputs (PORT 1) of a temperature sensor. If the temperature goes above the specified maximum (38°C), the system will open the bazzer (alarm system clock 500Hz). The system should also output the current temperature on the two 7 segment displays connected to port 0. B)- The 8051 will continuously monitor the (P3.4) of a Heart Pulse sensor. If the heart rate goes above the specified maximum (99 pulse), the system will open the bazzer (alarm system clock 500Hz).
