It’s two ways to analyze data
Answer:
1. Where,
2. From
Explanation:
In SQL query language when working on a database, a user can use certain clauses to carry out some functions.
Hence, The WHERE clause allows us to select only those rows in the result relation of the FROM clause that satisfy a specified predicate.
This is because the "Where clause" selects the rows on a particular condition. While the "From clause" gives the relation which involves the operation.
Answer:
usable capacity = 10 GB
Number of cylinders = 256
Block size = 4 KB
(1)Bytes in each cylinder = (10*230)/(256) = (10*222) = 40 MegaBytes
(2)Number of Blocks in each cylinder = (10*222)/(212) = 10K
(3)capacity of one track = 40 MegaBytes/(10*2) = 2 MB
Rotation speed = 3840 RPM
Number of rotations per second = 3840/60 = 64
Transfer rate = (2*64) = 128 MB/sec
