It is one of the most asked questions asked by computer students. It is asked in exams from classes 7th to higher education, in GK questions to Competitive exams. Still, most people are confused about it.

The data on the random access memory can be read, written, and erased any number of times. RAM is a hardware element where the data being currently used is stored. It is a volatile memory. Types of RAM:.

Difference Between RAM and ROM

RAM, which stands for random access memory, and ROM, which stands for read-only memory, are both present in your computer. RAM is volatile memory that temporarily stores the files you are working on.

ROM is non-volatile memory that permanently stores instructions for your computer. Find out more about RAM. RAM is volatile memory, which means that the information temporarily stored in the module is erased when you restart or shut down your computer.

Because the information is stored electrically on transistors, when there is no electric current, the data disappears. Each time you request a file or information, it is retrieved either from the computer's storage disk or the internet. The data is stored in RAM, so each time you switch from one program or page to another, the information is instantly available. When the computer is shut down, the memory is cleared until the process begins again.

Volatile memory can be changed, upgraded, or expanded easily by users. Find out if your computer needs more memory. ROM is non-volatile memory, which means the information is permanently stored on the chip. The memory does not depend on an electric current to save data, instead, data is written to individual cells using binary code.

Non-volatile memory is used for parts of the computer that do not change, such as the initial boot-up portion of the software, or the firmware instructions that make your printer run. Turning off the computer does not have any effect on ROM. Non-volatile memory cannot be changed by users. All rights reserved. Neither Crucial nor Micron Technology, Inc.

What is the difference between ROM and RAM?

While ROM is a non-volatile memory that retains data even when the power gets off. Another major difference between the two is that RAM allows both read and write data operation. As against ROM allows read operation only. It allows read and write operation of data by the user. It is referred to as temporary memory because the data present in this memory last only till the time the power supply is on.


The primary difference between them is the lifetime of the data they store. SRAM retains its contents as long as electrical power is applied to the chip. If the power​.


11 Actual Difference Between RAM and ROM

It is read only memory. Use Used to store the data that has to be currently processed by CPU temporarily. It stores the instructions required during bootstrap of the computer. Volatility It is a volatile memory. It is a nonvolatile memory.

Every computer comes with a certain amount of physical memory which is actually chips that hold data. RAM is a part of hardware that stores operating system s application programs and currently running processes that can be accessed randomly, i. Data in RAM stays for only as long as the computer is running, and gets deleted as soon as computer is switched off. Computers are so designed that this RAM can be increased up to a certain capacity. Every computer comes fitted with this memory that holds instructions for starting up the computer.

A ROM chip is a non-volatile storage medium, which means it does not require a constant source of power to retain the information stored on it. By contrast, a RAM chip is volatile , which means it loses any information it is holding when the power is turned off. A ROM chip is used primarily in the startup process of a computer, whereas a RAM chip is used in the normal operations after the operating system is loaded. A RAM chip temporarily stores files in use on a computer, like a document you're writing, an image you're editing, or data for a game you're playing. Using a non-volatile storage medium is the only way to begin this process for computers and other devices.

RAM vs. ROM

Это и был Санта-Крус, квартал, в котором находится второй по величине собор в мире, а также живут самые старинные и благочестивые католические семьи Севильи. Беккер пересек мощенную камнем площадь. Единственный выстрел, к счастью, прозвучал слишком поздно. Беккер на своем мотоцикле скрылся в узком проходе Каллита-де-ля-Вирген.

Слишком рано. Беккер беззвучно выругался. Уже два часа утра. - Pi'dame uno.

Сомнений не. В ярком свете уличного фонаря на углу Беккер увидел. Молодые люди поднялись по ступенькам, и двигатель автобуса снова взревел.

Беккер набрал первый из трех номеров. - Servicio Social de Sevilla, - прозвучал приятный женский голос. Беккер постарался придать своему испанскому тяжелый немецкий акцент: - Hola, hablas Aleman. - Нет, но я говорю по-английски, - последовал ответ. Беккер перешел на ломаный английский: - Спасибо.

Наверное, она подумает бог знает что: он всегда звонил ей, если обещал. Беккер зашагал по улице с четырехполосным движением и бульваром посередине. Туда и обратно, - мысленно повторял.  - Туда и обратно. Он был настолько погружен в свои мысли, что не заметил человека в очках в тонкой металлической оправе, который следил за ним с другой стороны улицы.

Подобно айсбергу машина скрывала девяносто процентов своей массы и мощи под поверхностью. Ее секрет был спрятан в керамических шахтах, уходивших на шесть этажей вниз; ее похожий на ракету корпус окружал лабиринт подвесных лесов и кабелей, из-под которых слышалось шипение фреоновой системы охлаждения. Генераторы внизу производили постоянный низкочастотный гул, что делало акустику в шифровалке какой-то загробной, присущей миру призраков. ТРАНСТЕКСТ, подобно всем великим технологическим достижениям, появился на свет в силу необходимости.

 Дэвид… - тихо простонала .

    The key difference between RAM and ROM is that RAM is basically a read-write memory whereas, ROM is a read only memory. RAM temporarily stores the data that have to be processed by CPU currently. On the other hands, ROM stores the instructions that are required during Bootstrap. RAM is a volatile memory.
