- Difference Between Serial And Random Access Memory Defined
RAM (Random Access Memory) is a fast accessible memory that stores data during its operation while ROM (Read Only Memory) stores permanent data that is used for its functions, such as the information for booting the computer.Thus, the key difference between RAM and ROM is in the way the data is stored in them; the storage in RAM is temporary whereas the storage in ROM is permanent. RAM (Random Access Memory) is the hardware in a computing device where the operating system (), application programs and data in current use are kept so they can be quickly reached by the device's processor. Specifically, why does this Wikipedia article on Direct Access Storage Devices distinguish between the two: whereas this article on random access doesn't: In computer science, random access (sometimes called direct access) is the ability to access an element at an arbitrary position in a sequence in equal time, independent of sequence size.
In computing, (SAM) is a class of data storage devices that read stored data in a sequence. This is in contrast to random access memory (RAM) where data can be accessed in any order. Sequential access devices are usually a form of magnetic storage or optical storage.[1][2]
While sequential access memory is read in sequence, arbitrary locations can still be accessed by 'seeking' to the requested location. This operation, however, is often relatively inefficient (see seek time, rotational latency).
Magnetic sequential access memory is typically used for secondary storage in general-purpose computers due to their higher density at lower cost compared to RAM, as well as resistance to wear and non-volatility. Magnetic tape is a type of sequential access memory still in use; historically, drum memory has also been used.
