Answer and Explanation:
Given that total number of records in a file = 100000
Each record consists of= 240 bytes
Given that B= 2400 bytes.
Then total blocks in file = 100000 records * 240 / 2400
= 10000 blocks.
Time that will take for exhaustive read
= s + r + b.btt
= 16 + 8.3 + (10000) * 0.8
= 8024.3 msec
Now as per given X be the number of records that are searched randomly and it takes more than exhaustive read time.
Hence, X (s + r + btt) > 8024.3
X (16+8.3+0.8) > 8024.3
X > 8024.3/25.1
So that, X > 319.69
Hence, atleast 320 random reads should be made to search the file
Answer:
metrics
Explanation:
Given that Metrics is Metrics is an accepted technique of measuring quantities of elements or commodities.
It is used in all facets of human activities particularly in value measurement such as production operation, financial assessment, comparison purposes, etc.
Hence, In addition to benchmark testing, performance measurements, called METRICS, can monitor the number of transactions processed in a given period, the number of records accessed, and the volume of online data.
In the business cycle, the term that best fits the labeled point on the graph of Production output vs Time is Contraction
False is the answer for this question i just did a test on E2020 and it was false because it gave me the answer the other person is wrong just to let you know
