Comptia A+ Core 1 Exam: Guide To Computing Infrastructure (mindtap Course List)
- A company that has engaged in a business that requires fast response times has just received a bid for a new system that includes much more storage than was specified in the requirements document. When the company questioned the vendor about the increased storage, the vendor said he was bidding a set of the smallest-capacity disk drives that the company makes. Why didn’t the vendor just bid fewer disks?arrow_forwardThe disk specification in Figure 7.15 gives a data transfer rate of 60MB per second when reading from the disk, and 320MB per second when writing to the disk. Why are these numbers different? (Hint: Think about buffering.)arrow_forwardConsider a disk with a sector size of 512 bytes, 2000 tracks per surface, 50 sectors per track, five double- sided platters, and average seek time of 10 msec. 1. What is the capacity of a track in bytes? What is the capacity of each surface? What is the capacity of the disk? 2. How many cylinders does the disk have? 3. Give examples of valid block sizes. Is 256 bytes a valid block size? 2048? 51200arrow_forward
- The need of wear leveling in solid-state drives is not something that can be overstated. Wearleveling, as we have previously discussed, is fundamental for the constant updating of virtual memory pagefiles. Why does wearleveling exacerbate the problem with pagefiles?arrow_forwardThere is a lot of talk concerning iCloud storage on the internet. How did the operation go? Was it easy or difficult? Do you think keeping files in the iCloud will make it simpler to manage them? Do you anticipate using this system again in the future? What makes you believe that?arrow_forwardExplain how a DVD manufacturer can advertise that a DVD can hold 4.7 GB, but Explorer reports theDVD capacity as 4,706,074,624 bytes or 4.38 GB.a. Manufacturers are allowed to overadvertise their products.b. The manufacturer measures capacity in decimal and the OS measures capacity in binary.c. The actual capacity is 4.7 GB, but the OS requires overhead to manage the DVD and the overheadis not included in the reported DVD capacity.d. The DVD was formatted to have a capacity of 4.38 GB, but it could have been formatted to have acapacity of 4.7 GB.arrow_forward
- A manufacturer wishes to design an array of hard disks in a server a capacity of 512gb or more. If the technology used to manufacture the disk allows 2048-byte sectors, 4096 sectors/track and 8192 tracks/platter. How many disks are required, assuming two platters/disk?arrow_forward108. Which of the following is a measure of reliability of a disk? a. Seek time b. Average latency time c. Mean time to failure d. Average seek timearrow_forwardCreating a RAID array is a way for producing live backups of physical hard drives; however, doing so willower the amount of available capacity on the physical hard drive. Alternatively, would you like to have backup at the cost of half of your available disc space? The ideal RAID configuration for a home computer system with frequent power outages that may result in hard disc failures is determined by the frequency of power outages.arrow_forward
- 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.arrow_forward1. In case of SSD defragmentation is not recommended justify with reasons? 2. Why direct disk drive addressing is abstracted by the Logical Block Addressing? 3. Consider a disk with a sector size of 512 bytes, 2000 tracks per surface, 50 sectorsPer track, five double-sided platters, and average seek time of 10 msec.a) What is the capacity of a track in bytes?b) What is the capacity of each surface?c) What is the capacity of the disk?d) How many cylinders does the disk have?e) Give examples of valid block sizes. Is 256 bytes a valid block size? 2048?51200?f) If the disk platters rotate at 5400 rpm (revolutions per minute), what is theMaximum rotational delay?arrow_forwardWhat is the average time to read or write a 512-byte sector for a typical disk rotating at 15,000 RPM? The advertised average seek time is 4ms, the transfer rate is 100 MB/sec, and the controller overhead is 0.2ms. Assume that the disk is idle so that there is no waiting time. 512B sector, 15,000rpm, 4ms average seek time, 100MB/s transfer rate, 0.2ms controller overhead, idle diskarrow_forward
