In cost accounting, managing materials is a massive undertaking because materials often account for 50% or more of the total cost of production. Here is a breakdown of how costs are classified and how material inventory is managed.
## **1. Classification of Costs** Costs can be classified in several ways to help management understand their behavior and impact.
### **By Nature or Element** **Material:** The cost of commodities supplied to an undertaking.
* **Labor:** The cost of remuneration (wages/
Cost accounting is a specialized branch of accounting that focuses on capturing a company's total costs of production by assessing the variable costs of each step of production, as well as fixed costs. It is an essential tool for management to make informed decisions.
## **1. Nature of Cost Accounting**
Cost accounting is both an art and a science, serving as a critical internal subsystem of an organization's information system.
* **Internal Focus:** Unlike financial accounting, which provides information

Q)Explain RDD and its operations.
-RDD (Resilient Distributed Dataset)
An RDD (Resilient Distributed Dataset) is the fundamental data structure of Apache Spark. It is a fault-tolerant collection of elements that is distributed across multiple nodes in a cluster and can be processed in parallel.
RDDs are called resilient because they can automatically recover lost data using lineage information (i.e., how the data was created).
Key Features of RDD:
Distributed: Data is split across multiple machines.
