The correct answer is: C. Read/Write memory.
RAM (Random Access Memory) is a type of computer memory that can be accessed randomly, meaning that any byte of memory can be accessed without touching the preceding bytes. RAM is typically used to store data that is actively being used by the computer, such as the operating system, running programs, and open files.
RAM is volatile memory, which means that it loses its contents when the power is turned off. This is in contrast to non-volatile memory, such as hard drives and solid-state drives, which retain their contents even when the power is turned off.
There are two main types of RAM: dynamic RAM (DRAM) and static RAM (SRAM). DRAM is the most common type of RAM, and it is used in most computers. SRAM is more expensive than DRAM, but it is faster and has a longer lifespan.
RAM is an essential component of any computer. It provides the computer with the temporary storage space it needs to run programs and access data. Without RAM, the computer would not be able to function.
Here is a brief explanation of each option:
- A. Read-only memory (ROM) is a type of memory that can only be read from, not written to. ROM is typically used to store firmware, which is the software that controls the basic functions of a computer.
- B. Programmable read-only memory (PROM) is a type of ROM that can be programmed once, after which it can only be read from. PROM is typically used to store data that needs to be changed infrequently, such as the BIOS (basic input/output system).
- C. Read/Write memory (RAM) is a type of memory that can be both read from and written to. RAM is typically used to store data that is actively being used by the computer, such as the operating system, running programs, and open files.
- D. Erasable programmable read-only memory (EPROM) is a type of PROM that can be erased and reprogrammed. EPROM is typically used to store data that needs to be changed more frequently than data stored in PROM.
- E. None of the above.
