- Suppose that a disk drive rotates at 8000 RPM. It has an average seek time of 4 milliseconds. If its transfer rate is 15 Mbps, determine the average time it takes for a 15K byte request to be transferred from the time the disk starts the seek? From this, determine its throughput.Consider a disk pack with 16 surfaces, 128 tracks per surface and 256 sectors per track. 512 bytes of data are stored in a bit serial manner in a sector. Calculate the capacity of the disk pack and the number of bits required to specify a particular sector in the disk.Consider a disk pack with 16 surfaces, 128 tracks per surface and 256 sectors per track. 512 bytes of data are stored in a bit serial manner in a sector. The capacity of the disk pack and the number of bits required to specify a particular sector in the disk.?
- Consider a Disk I/O transfer, in which 1500 bytes are to be transferred, but number of bytes on a track is 1000, and rotation speed of disk is 1500 rps but the average time required to move the disk arm to the required track is 15 ms, then what will be total access time?Consider a disk drive specifications. with the following 16 surfaces, 512 tracks/surface, 512 sectors/ track, 1 KB/sector, rotation speed 3000 rpm. The disk is operated in cycle stealing mode whereby whenever one byte word is ready it is sent to memory; similarly, for writing, the disk interface reads a 4 byte word from the memory in each DMA cycle. Memory cycle time is 40 nsec. The maximum percentage of time that the CPU gets blocked during DMA operation?Suppose that a magnetic disk has an average seek time of 4 ms, a rotation rate of 5400 RPM, a transfer rate of 50 MB/second, a sector size of 512 bytes, and controller overhead of 2 ms. What is the average amount of time to read a single sector?
- Consider a disk that rotates at 3600 rpm. The seek time to move the head between ad- jacent tracks is 2 ms. There are 32 sectors per track, which are stored in linear order from sector 0 through sector 31. The head sees the sectors in ascending order. Assume the read/write head is positioned at the start of sector 1 on track 8. There is a main memory buffer large enough to hold an entire track. Data is transferred between disk locations by reading from the source track into the main memory buffer and then writing the date from the buffer to the target track. a. How long will it take to transfer sector 1 on track 8 to sector 1 on track 9? b. How long will it take to transfer all the sectors of track 8 to the corresponding sec- tors of track 9?Consider a computer system that has the following characteristics: The memory bus runs at 400 MHz. The memory bus is 8 bytes wide. Accessing a memory address in memory requires 8 memory bus cycles. The disk drives can each read a block every 4 milliseconds. Disk blocks read are 8 kilobytes each. Assume Direct Memory Access from the disk drive. What is the highest percentage of the memory bus capacity that could be consumed by the disk’s Direct Memory Access if there are 4 disk drives in use?Consider a disk with following specifications: 20 surface, 1000 tracks/surface, 16 sectors/track, data density 1 KB/sector, rotation speed 3000 rpm. The operating system initiates the transfer between the disk and the memory sector-wise. Once the head has been placed on the right track, the disk reads a sector in a single scan. It reads bits from the sector while the head is passing over the sector. The read bits are formed into bytes in a serial-in-parallel-out buffer and each byte is then transferred to memory. The disk writing is exactly a complementary process. For parts (c) and (d) below, assume memory read-write time = 0.1 microsecond/ byte, interrupt driven transfer has an interrupt overhead = 0.4 microseconds, the DMA initialization and termination overhead is negligible compared to the total sector transfer time. DMA requests are always granted. (a) What is the total capacity of the disk? (b) What is the data transfer rate? (c) What is the percentage of time the CPU is…
- Consider a hypothetical system, a 48 - bit width main memory with a capacity 256 TB is build using 64 T x 8-bit DRAM chips. The number of rows of memory cells in the DRAM is 225. The time taken to perform one Refresh operation is 40 ns. The refresh period is 5 s. Fraction of total memory bandwidth is lost to refresh cycle is (up to two decimal places).In a dynamic random access memory (DRAM) computer chip, each memory cell chiefly consists of a capacitor for charge storage. Each of these cells represents a single binary-bit value of 1 when its 35-fFfcapacitor (1fF=10^−15F) is charged at 1.5 V, or 0 when uncharged at 0 V. A)When it is fully charged, how many excess electrons are on a cell capacitor's negative plate? B) After charge has been placed on a cell capacitor's plate, it slowly "leaks" off (through a variety of mechanisms) at a constant rate of 0.30 fC/s. How long does it take for the potential difference across this capacitor to decrease by 1.0% from its fully charged value? (Because of this leakage effect, the charge on a DRAM capacitor is "refreshed" many times per second.) Express your answer to two significant figures and include the appropriate units.Consider a CPU that operates with a data transfer rate of 30 Mbytes/s. The data is transferred byte-wise and the CPU has to transfer 30bytes of data, and the size of the Status register is 4 bytes. What is the total time needed to perform the data transfer?
