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: Conventions

Answer:
painter = {'name' : "Vincent van Gogh", 'artworks': ["The Starry Night","Irises","The Potato Eaters"],'bornDate': "March 30, 1853", 'eyeColor': "July 29, 1890", 'diedDate': "July 29, 1890"} #this is a code which holds the questions defined value in a painter variable.
Explanation:
- The above question wants to declare a variable that is in the form of a key and value pair.
- The above question states to define name, artworks,eyeColor, and dieddate as a key and the other is defined as a value.
- when a user wants to access the whole dictionary then he can do with the help of the painter variable.
- But when he wants to access the value of any particular key, then he can do it with the help of the key name as "painter[keyname]".
