TYPES OF MEMORY
DEFINITIONS AND TYPES OF MEMORY
Currently the term used to describe the memory data storage space that comes into the computer chip, and the storage itself is used to describe memory in the disk. In addition, sometimes the term memory is also commonly used as an external memory device or a memory device that can be taken anywhere. Some of today’s computers also use virtual memory, which has great power on a hard drive.
Each computer is now equipped with memory, and memory is usually called main memory or RAM is called. In a computer main memory is placed in the form of a row of metal boxes.
Each computer can accommodate the information in the form of bytes. Computer that has 1 megabyte memory can hold more than one also bytes of information or character.
There are several types of memory, and below this is the type and description
RAM (random access memory): This memory is main memory. The term of the RAM memory is used for the function to read and write data. With these functions you can perform two activities at once, the writing of the RAM and read data from RAM. This is very different from the ROM, which only allows you to be able to read the data. Most data has a level of stability that is less and it indicates that the electric power come regulating content on the RAM path. And if at any time power is lost, the data automatically to the RAM will be lost.
ROM (read-only memory): Nearly a large number of computers have ROM or Read Only Memory which holds instructions to turn on a computer. Unlike RAM, ROM can not be used to write data.
PROM (programmable read-only memory): A PROM is a memory chip that can store programs. But once the PROM digu0nakan, we will not be able to clean and restore other data.
EPROM (erasable programmable read-only memory): EPROM is a special type of PROM memory, EPROM which can be removed by using ultraviolet light.
EEPROM (Electrically erasable programmable read-only memory): EEPROM is a special type of PROM, EEPROM which can be removed by using the electric voltage.
