QQ.1. What is the role of memory in a computer? What are the different types of memories used in a Computer? Explain the uses of each type of memory. Find size range of these memories.
- Memory stores data/instructions for CPU, bridging speed gap between CPU and I/O devices.
- Primary memory (RAM, ROM, Cache) is directly accessible by CPU for immediate processing.
- RAM (4-32GB) is volatile, storing active programs/data for quick CPU access.
- ROM (KB-MB) is non-volatile, stores essential boot firmware like BIOS permanently.
Answer: Memory is a fundamental component of a computer system, serving as temporary or permanent storage for data and instructions that the Central Processing Unit (CPU) needs to access. Its primary role is to bridge the speed gap between the CPU, which operates extremely fast, and slower input/output devices. Memory enables the computer to store operating system programs, application software, and the data being actively processed, allowing the CPU to retrieve them quickly. Without memory, a compute...
