Right Answer:
Correlation is a statistical measure that indicates the extent to which two variables fluctuate together, while causation implies that one variable directly affects or causes a change in another variable.

Right Answer:
The different types of data analysis are:

1. Descriptive Analysis
2. Diagnostic Analysis
3. Predictive Analysis
4. Prescriptive Analysis
5. Exploratory Analysis

1. Bar Charts
2. Line Graphs
3. Pie Charts
4. Scatter Plots
5. Histograms
6. Heat Maps
7. Box Plots
8. Area Charts

Right Answer:
Clustering in data analysis is the process of grouping similar data points together based on their characteristics, without prior labels. It is an unsupervised learning technique. In contrast, classification involves assigning predefined labels to data points based on their features, using a supervised learning approach.

Right Answer:
Regression analysis is a statistical method used to examine the relationship between one dependent variable and one or more independent variables. It is used to predict outcomes, identify trends, and understand the strength of relationships in data.

Right Answer:
Dynamic lookup is used in Informatica when you need to update existing records or insert new records in a target table based on incoming data. It allows you to look up data dynamically during the session. Yes, you can generate surrogate keys using dynamic lookup. It can be used for Slowly Changing Dimension (SCD) Type 2 mapping because it helps manage historical data by allowing you to insert new records with updated values while preserving the old records.

Right Answer:
The couple elimination problem involves identifying and removing pairs of elements (couples) from a collection based on specific criteria. A common approach is to use a stack data structure to efficiently manage the pairs. As you iterate through the collection, you push elements onto the stack, and when you find a matching couple, you pop them off the stack. This continues until all possible couples are eliminated. The final stack will contain the remaining elements that could not be paired.

Right Answer:
The CPU, or Central Processing Unit, is the main component of a computer that performs calculations and executes instructions, effectively acting as the brain of the computer.

It provides a collaborative environment allowing users to manage content, create sites for teams, collaborate on documents, manage tasks, and participate in discussions. It supports collaboration through features like document sharing, version control, workflows, social collaboration tools (blogs, wikis, forums), and activity feeds.

Right Answer:
The ARM Compiler is a software development tool used to compile code for ARM architecture processors. It translates high-level programming languages like C and C++ into machine code that can be executed by ARM-based devices, optimizing performance and efficiency for embedded systems and applications.

Right Answer:
The different components of the ARM toolchain are:

1. **Compiler** (e.g., ARM GCC)
2. **Assembler** (e.g., ARM Assembler)
3. **Linker** (e.g., ARM Linker)
4. **Debugger** (e.g., ARM Debugger)
5. **Libraries** (e.g., ARM Standard Libraries)
6. **Build Tools** (e.g., Make, CMake)

Right Answer:
Startup files in an ARM environment are assembly or C source files that initialize the system before the main program runs. They typically set up the stack pointer, initialize global variables, and call the main function. These files ensure that the hardware and software environment is correctly configured for the application to run.

Right Answer:
