What is digital video disc read only memory?
Digital versatile disc-read only memory (DVD-ROM) is a read-only digital versatile disc (DVD) commonly used for storing large software applications. It is similar to a compact disk-read only memory (CD-ROM) but has a larger capacity. A DVD-ROM stores around 4.38 GB of data. A CD-ROM usually stores 650 MB of data.
Is DVD a read-only device?
DVD-ROM stands for Digital Versatile Disk-Read Only Memory. DVD-ROM is a data storage device in which information, once written, cannot be modified.
What is the difference between DVD and RAM?
The Differences Between DVD-ROM and DVD-RAM The DVD-RAM is read and write, while the DVD-ROM is read-only. This means that once the data is encoded, the disc is in a fixed state and cannot be changed. This makes it ideal for storing data that does not need to be rewritten or changed like a movie.
What is the difference between DVD-ROM and DVD-RAM?
The Differences Between DVD-ROM and DVD-RAM Generally, DVD-RAM is used to store data, and DVD-ROM is used for movies and supplementary music presentations.

What is difference between flash memory and SRAM?
By their nature, flash memory and RAM are faster than storage alternatives, such as hard disk and tape. In terms of flash memory vs. RAM speed, RAM is the faster of the two, but it is also more expensive. There are two types of RAM commonly used in a computer system: dynamic RAM (DRAM) and static RAM (SRAM).
What is the difference between SDRAM and SRAM?
1. SRAM is static (doesnÃt need power-refreshing) while SDRAM is dynamic (needs power-refreshing periodically). 2. SDRAMÃs access speed is clock dependent while SRAM accesses directly.
