Read-only memory ROM is a type of non-volatile memory used in computers and other electronic devices. Data stored in ROM cannot be electronically modified after the manufacture of the memory device. Read-only memory is useful for storing software that is rarely changed during the life of the system, also known as firmware. Software applications like video games for programmable devices can be distributed as plug-in cartridges containing ROM.

Here are the top five differences between the two types of memory:. RAM is the memory available for the operating system, programs and processes to use when the computer is running. ROM is the memory that comes with your computer that is pre-written to hold the instructions for booting-up the computer. RAM requires a flow of electricity to retain data e. ROM will retain data without the flow of electricity e. RAM is a type of volatile memory.

Primary storage, or memory, means the space on your hard drive that is briefly used for working space. This usually occurs in a chip. It is also temporary storage, holding software instructions and short-term working memory for the processor. RAM can be increased in most computers by using the expandable memory slots. Ram video. It is used to store data that is currently being used. Random access memory or RAM is a form of data storage used in computers.

Nearly every computing-capable device needs RAM. Take a look at your favorite device e. Although all RAM basically serves the same purpose, there are a few different types commonly in use today:.

Our Cloud Computing page explains all about the benefits and drawbacks of using the cloud for storage or services. Our Data Storage Capacity page explains all about the various units of storage. Hard disk drives are non-volatile magnetic storage devices capable of remembering vast amounts of data. The disk surface is divided into concentric circles tracks and sectors wedges. Solid state drives are non-volatile storage devices capable of holding large amounts of data. They use NAND flash memories millions of transistors wired in a series on a circuit board , giving them the advantage of having no mechanical moving parts and therefore immediate access to the data. Solid state drives perform faster then traditional hard disk drives, however they are significantly more expensive.

The computers and other tech devices your company uses rely on a handful of basic technologies. One of them is the memory, which is where your software does what it does.

Used in calculators and peripheral devices. Types of ROM. RAM is the memory available for the operating system, programs and processes to use when the computer is running. ROM is the memory that comes with your computer that is pre-written to hold the instructions for booting-up the computer.

We have discussed quite a few times in this course about how the reads and writes data from or to memory. But we know that unlike microcontrollers that have a certain amount of built-in memory, microprocessors do not have their own memory except for a few registers. So, where does read and write data?

Nearly every computing-capable device needs RAM. Take a look at your favorite device e. Although all RAM basically serves the same purpose, there are a few different types commonly in use today:.
