Learn and Master C Programming - Memory & Storage

The lecture covers the basics of computer memory, focusing on RAM and ROM. RAM is described as volatile and temporary, while ROM is non-volatile and used for firmware. The lecture also explains memory addressing, distinguishing between physical and virtual addresses. Storage types, including HDDs and SSDs, are introduced, highlighting their differences in speed, cost, and data retention. The session concludes with a summary of these concepts, setting the stage for future discussions on software.

What is the primary characteristic of RAM that differentiates it from other types of memory?

• It is slower than hard drives.

• It is used for storing firmware.

• It is non-volatile.

• It loses data when power is off.

Which type of memory retains its data even when the computer is turned off?

• Virtual Memory

• Cache

• ROM

• RAM

What is the main purpose of virtual memory in a computer system?

• To increase the speed of the CPU.

• To allow programs to use more memory than physically available.

• To store the operating system permanently.

• To replace the need for RAM.

How does the operating system utilize virtual addresses?

• By directly accessing the hardware.

• By providing programs with a simplified view of memory.

• By storing data permanently.

• By increasing the speed of data retrieval.

What is a byte in terms of memory data?

• A single bit of data.

• A 32-bit data unit.

• A 16-bit data unit.

• An 8-bit data unit.

Which type of storage is known for being faster and quieter than traditional hard disk drives?

• Optical Drive

• Solid-State Drive (SSD)

• ROM

• RAM

What is the main disadvantage of using hard disk drives compared to RAM?

• They are slower.

• They cannot store data permanently.

• They are more expensive.

• They are volatile.
