Test: Index Number - Question 1

### Which of the following addressing modes, facilitates access to an operand whose location is defined relative to the beginning of the data structure in which it appears?

Detailed Solution for Test: Index Number - Question 1

Index addressing modes facilitates access to an operand whose location is defined relative to the beginning of the data structure in which it appears.

In the indexed addressing mode, the content of a particular index register is appended to the address component of an instruction to obtain the effective address.
The index register refers to a particular CPU register that contains an index value. The address field of an instruction specifies the starting address of any data array in memory.
Using the index addressing mode, we get flexibility for specifying several locations of the memory.
Hence the correct answer is Index.

Test: Index Number - Question 2

### Which of the following are the major characteristics of index numbers?

Detailed Solution for Test: Index Number - Question 2
Index numbers have the following major characteristics:

They are expressed in percentages, representing relative changes.
They measure the net or relative changes in variables, such as prices or quantities.
They are used to measure changes over a period of time.
Therefore, all of the above statements (Option D) are correct.
Test: Index Number - Question 3

### Which of the following is dense index

Detailed Solution for Test: Index Number - Question 3

Indexing

Indexing is a way to optimize the performance of a database by minimizing the number of disk accesses required when a query is processed.
It is a data structure technique that is used to quickly locate and access the data in a database
There are the following type of Indexes

Primary index
It is maintained for the anchor value of block i,e one key-value per block maintained in Index file.

Clustering index
It is basically a mixed sort of Indexing i,e Dense as it is maintained for unique value (key)  and Sparse as it is not maintained for every value.

Test: Index Number - Question 4
The time period for which an index number is determined is known as ________.
Detailed Solution for Test: Index Number - Question 4
The time period for which an index number is determined is known as the "current period" (Option C). The base period is the reference period against which the changes are measured, and the normal period is not a commonly used term in index number calculations.
*Answer can only contain numeric values
Test: Index Number - Question 5

Consider a FAT-based file system which is stored on a disk of 900 GB. The data block size is 45000 bytes. The total overhead in each entry is 6 bytes in size. The maximum size of a file that can be stored on this disk is ______ GB (Compute the value up to 2 decimal places)

Detailed Solution for Test: Index Number - Question 5

Space occupied by overhead =  0.02 x 230 x  6 = 0.12 x 1030 B

Maximum file size = total file system size – space consumed by overhead
= 900  x  1030 – 0.12  x  1030

= 899.88 x 1030 B

= 899.88

Test: Index Number - Question 6

Which of the following statements is/are correct about average prices if the price index is 110?

Detailed Solution for Test: Index Number - Question 6

If the price index is 110, it means that prices have increased by 10 percent (Option A) relative to the base period. A price index of 100 would indicate no change, and values above 100 indicate an increase in prices.

Test: Index Number - Question 7

In a file allocation system, which of the following allocation scheme can be used to support efficient direct access if no external fragmentation is allowed?

Detailed Solution for Test: Index Number - Question 7

There is always the possibility of external fragmentation in contiguous allocation. Both the linked and the indexed allocation methods are completely free of any external fragmentation.

Test: Index Number - Question 8
Which of the following is the variation within two or more variables studied by the index?
Detailed Solution for Test: Index Number - Question 8
The variation within two or more variables studied by the index is referred to as a "composite index" (Option B). A composite index combines multiple variables or components into a single index number to represent overall changes.
Test: Index Number - Question 9

Which of the following is dense index

Detailed Solution for Test: Index Number - Question 9

Indexing

Indexing is a way to optimize the performance of a database by minimizing the number of disk accesses required when a query is processed.
It is a data structure technique that is used to quickly locate and access the data in a database
There are the following type of Indexes

Primary index
It is maintained for the anchor value of block i,e one key-value per block maintained in Index file.

Clustering index
It is basically a mixed sort of Indexing i,e Dense as it is maintained for unique value (key)  and Sparse as it is not maintained for every value.

Test: Index Number - Question 10
The weights used in a quantity index are ________.
Detailed Solution for Test: Index Number - Question 10
The weights used in a quantity index are Price.
In a quantity index, the focus is on measuring changes in the physical quantities of goods or services, rather than their values or prices. This type of index is often used to track changes in the physical volume or quantity of goods produced, consumed, or traded over time. The weights in a quantity index represent the relative importance of different items based on their prices, not their quantities or values. Therefore, the correct answer is Option C: Price.
