A)
GB>MB>KB>TB
B)
TB>MB>GB>KB
C)
MB>GB>TB>KB
D)
TB>GB>MB>KB
The correct ascending order of common memory units is: KB < MB < GB < TB. If written from largest to smallest, it becomes TB > GB > MB > KB. Therefore, option (d) is correct.
Why the others are incorrect:
- (a) GB > MB > KB > TB: incorrect because TB is larger than GB, so TB should come first in descending order.
- (b) TB > MB > GB > KB: incorrect because GB is larger than MB, so the order between MB and GB is wrong.
- (c) MB > GB > TB > KB: incorrect because TB is the largest among these units, and KB is the smallest.
High-yield memory hierarchy:
1 KB = 1024 bytes
1 MB = 1024 KB
1 GB = 1024 MB
1 TB = 1024 GB

The discriminant of the quadratic equation x^2 - 6x + 7 = 0 is -
A)
10
B)
15
C)
20
D)
25
For a quadratic equation ax^2 + bx + c = 0, the discriminant is D = b^2 - 4ac. Here, x^2 - 6x + 7 = 0, so a = 1, b = -6, and c = 7. Therefore, D = (-6)^2 - 4(1)(7) = 36 - 28 = 8. So the discriminant is 8. However, 8 is not listed in the options, which means the given options are incorrect. Among the provided choices, none is right. If the question intended a different equation or there is a printing error, that should be checked. Hence, mathematically the correct discriminant is 8, not 10, 15, 20, or 25.
