3. Data that is organized and processed becomes information.

Section C: True or False

1. True
2. False (RAM is temporary memory; ROM is permanent memory.)
3. False (A computer needs memory to store and process data.)

Section D: Short Answer Questions

1. Data is a collection of raw facts and figures before processing. It becomes information after it is organized.
2. Types of Memory in a Computer:
   • RAM (Random Access Memory): Stores data temporarily for active tasks.
   • ROM (Read-Only Memory): Permanent storage for system boot instructions.
   • Cache Memory: Fast memory storing frequently used data.
   • Hard Drive/SSD: Stores data permanently.

Section E: Long Answer Question

1. Role of Memory in a Computer System:
   Memory is an essential component of a computer. RAM helps in quick processing by storing temporary data, while ROM contains the necessary startup instructions for the computer. Storage devices like hard drives and SSDs keep permanent records of files, programs, and user data. Without memory, a computer cannot function effectively.
