Q1. Explain CMOS inverter?
Ans. 
CMOS inverter is a type of digital logic gate that implements logical NOT operation.
• CMOS inverter consists of a PMOS transistor connected in series with an NMOS transistor.

• When input is high, PMOS conducts and NMOS is off, output is low.

• When input is low, NMOS conducts and PMOS is off, output is high.

• CMOS inverters are widely used in digital circuits for logic operations.

• Example: Inverter gate in a CMOS technology-base

Q2. Write an sql query to change rows into columns and vice versa
Ans. 
Use SQL pivot function to change rows into columns and vice versa
• Use the PIVOT function in SQL to transform rows into columns

• Use the UNPIVOT function in SQL to transform columns into rows

• Example: SELECT * FROM table_name PIVOT (SUM(value) FOR column_name IN (value1, value2, value3))

• Example: SELECT * FROM table_name UNPIVOT (value FOR column_name IN (value1, value2, value3))

Q3. Write an sql query to fetch duplicate rows in a table
Ans. 
SQL query to fetch duplicate rows in a table
• Use GROUP BY and HAVING clause to identify duplicate rows

• Select columns to check for duplicates

• Example: SELECT column1, column2, COUNT(*) FROM table_name GROUP BY column1, column2 HAVING COUNT(*) > 1;

Q4. Diff between repartition and colaesce, clustering and partitioning in bq
Ans. 
Repartition increases or decreases the number of partitions in a DataFrame, while coalesce only decreases the number of partitions. Clustering is used for organizing data within a partition, while partitioning is dividing data into logical units.
• Repartition increases or decreases the number of partitions in a DataFrame, which can be useful for parallelism and performance optimization.

• Coalesce only decreases the number ...read more

Q1. How to predict if a 32 bit number is divisible by 8, draw a circuit using gates
Ans. 
To predict if a 32 bit number is divisible by 8, design a circuit using gates.
• Use a circuit with AND, OR, and NOT gates to check if the last three bits of the number are all zeros.

• If the last three bits are zeros, then the number is divisible by 8.

• For example, if the 32 bit number is 11010000, the last three bits are zeros, so it is divisible by 8.

Q1. What is normalization
Ans. 
Normalization is the process of organizing data in a database to reduce redundancy and improve data integrity.
• Normalization is used to eliminate data redundancy by breaking up tables into smaller, related tables.

• It helps in reducing data anomalies such as insertion, update, and deletion anomalies.

• Normalization is achieved through a series of stages called normal forms, with the most common being First Normal Form (1NF)...read more
