RAM Vs. ROM | Animation

Key Technological Concepts:

• RAM (Random Access Memory)
  • Definition: Temporary storage that allows devices to perform tasks quickly.
  • Volatility: RAM is volatile, meaning all data is lost when the device is powered off.
  • Types of RAM:
    • Dynamic RAM (DRAM): Composed of transistors and capacitors; requires refreshing every few milliseconds; latency of around 100 nanoseconds.
    • Static RAM (SRAM): Made of interlocking transistors; does not need refreshing, making it faster but more expensive.
  • Storage Capacity: Ranges from 1 to 256 gigabytes per chip.
• ROM (Read-Only Memory)
  • Definition: Permanent storage that retains data even when the device is powered off.
  • Non-volatility: ROM is non-volatile, meaning it does not require power to maintain data.
  • Function: Stores instructions necessary for booting up the computer (bootstrap process).
  • Storage Capacity: Typically ranges from 4 to 8 megabytes per chip.
  • Speed: Generally slower and cheaper than RAM.

Comparison Summary:

• Volatility: RAM is volatile; ROM is non-volatile.
• Data Access: RAM allows read, erase, and modify; ROM is read-only.
• Usage: RAM is used for current instruction processing; ROM stores boot instructions.
• Physical Size: RAM sizes vary by device type; ROM size varies based on its application.
