Which type of memory allows for information to be read from and written to?

• A. Read-Only Memory
• B. Dynamic RAM
• C. Static RAM
• D. EEPROM

Answer: (B)

The correct answer is Dynamic RAM (DRAM). This type of memory is designed for both reading from and writing to memory cells, which allows it to store data temporarily while the computer is in use. Unlike Read-Only Memory (ROM), which is fixed and can only be read, or EEPROM, which is primarily for data retention after power loss but has slower write capabilities compared to DRAM, Dynamic RAM is used in most applications where high-speed data access is needed, such as in main memory for computers. DRAM continually needs to be refreshed to maintain the data, which is a key characteristic that distinguishes it from other types of memory like Static RAM (SRAM), which holds data without needing constant refreshing but is used more for cache memory due to its higher cost. Thus, the ability of Dynamic RAM to facilitate both read and write operations makes it essential for the dynamic processing requirements of modern computing environments.
