need help answering these 2 questions Q1. A hypothetical disk drive has the speciﬁcations shown below. Find the average access time for a block (sector) of data. I want the answer in milliseconds, and you need to reduce your answer to a simple ﬁnal value. • 32 sectors per track • 3600 RPM speed • 7 millisecond average seek time ________________________ Q2. Transaction processing is chieﬂy concerned with I/O rate: number of disk accesses per second, as opposed to data rate, and the I/O speed versus CPU speed in terms of Transactions Per Second (TPS). Assume the following information: • CPU has the performance of 800 MIPS. • Each transaction requires 2 disk reads plus 2 disk writes. • The database software executes 40000 instructions to process a transaction. • The operating system uses 15000 instructions for each disk read or write access. • The I/O bus and memory are capable of sustaining 1000 MB/sec of data transfer without interfering with the CPU. • Each read/write access transfers 100 bytes. a. What is the peak performance of the CPU in terms of TPS? b. What is the peak performance of the I/O bus system in terms of TPS? Thank you in advance.
