A kind of memory chip that stores data and instructions permanently is:Question 49Answera.EEPROMb.RAMc.SRAMd.ROM

Break Down the Problem

1. Identify the types of memory chips mentioned: EEPROM, RAM, SRAM, and ROM.
2. Understand the function of each type of memory chip.
3. Determine which type of memory chip stores data and instructions permanently.

Relevant Concepts

1. EEPROM (Electrically Erasable Programmable Read-Only Memory): A non-volatile memory that can be electrically erased and reprogrammed.
2. RAM (Random Access Memory): A volatile memory that temporarily holds data and instructions while in use.
3. SRAM (Static Random Access Memory): A type of volatile memory that is faster than RAM but also temporary.
4. ROM (Read-Only Memory): A non-volatile memory that stores data and instructions permanently, typically used for firmware.

Analysis and Detail

• EEPROM retains its data when power is turned off but is primarily used for smaller amounts of data.
• RAM loses its data once the power is turned off, making it unsuitable for permanent storage.
• SRAM also loses its data when powered off.
• ROM, on the other hand, is specifically designed to store firmware permanently, meaning it retains its content even when powered down.

Verify and Summarize

• Between the options given, ROM is recognized for its permanence in storing data and instructions, making it the correct choice for permanent storage.

Final Answer

The correct answer is d. ROM.
