Describe the Different Memory Types: Cache, RAM, ROM, EEPROM, and Virtual

Question

The Answer is Cache, sometimes called RAM cache or cache memory, is high-speed memory that a processor can access more rapidly than memory elsewhere on the motherboard. The amount of cache memory, as well as its location, affects performance. Cache capacity is usually expressed in megabytes (MB). RAM (random access memory)is a temporary holding area for data, program instructions, and the operating system. In a personal computer, RAM is usually several chips or small circuit boards that plug into the motherboard inside the computer's system unit. Next to the processor, RAM is one of the most expensive computer components. The amount of RAM in a computer can affect the overall price of a computer system. Along with processor speed, RAM capacity is the other most important factor in determining and comparing the power of a computer system. ROM (read-only memory)is a type of memory circuitry that holds the computer's startup routine. ROM is housed in a single integrated circuit that is plugged into the motherboard. ROM is permanent and nonvolatile, which means the instructions in ROM remain in place even when the computer power is turned off. The only way to change the ROM instructions is to replace the ROM chip. EEPROM (electrically erasable programmable read-only memory)is a nonvolatile chip that requires no power to hold data. EEPROM is a type of memory that is more permanent than RAM but less permanent than ROM. When you change the configuration of your computer system, the data in EEPROM must be updated. Virtual memory is an area of the hard drive that the operating system uses to store parts of a program or data file until they are needed. By selectively exchanging the data in RAM with the data in virtual memory, your computer effectively gains almost unlimited memory capacity. However, too much dependence on virtual memory can have a negative effect on your computer's performance because getting data from a mechanical device, such as a hard drive, is much slower than getting data from an electronic device, such as RAM.
