Differences between RAM and ROM in Computers and How they Work & Function
Rancakmedia.com – The difference between RAM and ROM must be understood even if both computers have memory states. In principle, RAM and ROM have different roles, tasks and ways of working.
Random Access Memory (RAM) and Read Only Memory (ROM) are memory technologies from computers to cell phones. Both have different ways of working and functions, even though they have the same status as data storage.
What is RAM?
Reporting from Freefeast, RAM is a memory system that is able to back up all data within a certain time. RAM can store data without consuming power because it is connected to a computer system program.
However, RAM is often referred to as short term memory. Because, after power loss, all data will be lost. To run the operating system, there is a minimum RAM consumption limit, such as 1GB, 2GB, 4GB, and so on.
RAM is divided into two types, namely Dynamic Random Access Memory (DRAM) and Synchronous Random Access Memory (SRAM) (SRAM).
What are ROMs?
Meanwhile, ROM has the capacity to store data permanently. When the power supply is disconnected, the ROM will not lose its data, because it is run and maintained by a small battery that is placed in the computer.
Regarding the tasks, ROM has the main role for data input and output, as well as controlling software programs.
Usually ROM is in the form of chips, placed on the motherboard and circuit boards. Its purpose is to control the input and output of the basic data management system, as well as reading and writing to devices.
ROM provides the necessary instructions on how the device is connected to other components. ROM is usually used as firmware.
Firmware is a collection of programs that are embedded into computer hardware components. ROM is widely distributed among optical storage media, such as CD-ROM, CD-R (Compact Disc Recordable), and CD-RW (Compact Disc Re-Writeable) (Compact Disc Re-Writeable).
Difference between ROM and RAM
Meanwhile according to the Geeks for Geeks website, here are the differences between RAM and ROM:
- Temporary storage
- Volatile (easily 'evaporates')
- Used in normal operation
- Write data faster
- Permanent Storage
- Non-volatile (not easy to 'evaporate')
- Used for the computer startup process
- Writing data is slower
In basic words, ROM is a place to store internal data that can also run operating systems and other systems. RAM is similar to the main memory of a device which can be accessed to run programs.
Units of RAM and ROM are usually referred to as megabytes to gigabytes. For RAM, processing speed is usually measured in nanoseconds.
