Which type of ROM can be electrically erased?

Answer: The type of ROM that can be electrically erased is EEPROM (Electrically Erasable Programmable Read-Only Memory). EEPROM can be erased and reprogrammed using electrical charge, making it more versatile compared to other types of ROM.

What is RAM?

Answer: RAM (Random Access Memory) is a type of computer memory that can be accessed randomly; any byte of memory can be accessed without touching the preceding bytes. Here are the options and the correct answer:

  • a. It is the first level of memory used by the computer in all of its operations.
  • b. It is memory that can be reached by any subsystem within a computer, and at any time.
  • c. It is memory that is used for short-term temporary data storage within the computer.
  • d. It is memory that can be used and then automatically reset, or cleared, after being read from or written to.

The correct answer is c. It is memory that is used for short-term temporary data storage within the computer. RAM is used for storing data temporarily while the computer is running and is cleared when the computer is turned off.

What is the major difference between SRAM and DRAM?

Answer: The major difference between SRAM (Static RAM) and DRAM (Dynamic RAM) lies in how they store data and their performance characteristics. Here are the options and the correct answer:

  • a. SRAMs can hold data via a static charge, even with power off.
  • b. DRAMs must be periodically refreshed.
  • c. The only difference is the terminal from which the data is accessed.

The correct answers are:

  • b. DRAMs must be periodically refreshed.
  • a. SRAMs can hold data via a static charge, even with power off.

To clarify:

  • SRAM (Static RAM) retains data as long as power is supplied and does not need to be periodically refreshed. It uses bistable latching circuitry to store each bit, making it faster and more reliable but also more expensive and with lower density compared to DRAM.
  • DRAM (Dynamic RAM) stores data in capacitors that must be periodically refreshed to maintain the data. This makes DRAM slower than SRAM but allows for higher density and lower cost, making it suitable for main memory in computers.
