In computer science, random-access machine (RAM or RA-machine) is a model of computation that describes an abstract machine in the general class of register machines. The RA-machine is very similar to the counter machine but with the added capability of 'indirect addressing' of its registers.
Random access (more precisely and more generally called direct access) is the ability to access an arbitrary element of a sequence in equal time or any datum from a population of addressable elements roughly as easily and efficiently as any other, no matter how many elements may be in the set.
Dec 16, 2021 · Random Access Machine or RAM model is a CPU. It is a potentially unbound bank of memory cells, each of which can contain an arbitrary number or character. Memory cells are numbered and it takes time to access any cell in memory or say all operations (read/write from memory, standard arithmetic, and Boolean operations) take a unit of time.
Jul 21, 2022 · It successfully ran a program from memory in June 1948. Computing pioneers Frederic C. Williams, Tom Kilburn, and Geoff Tootill developed and built the machine and its storage system—the ...

The IBM 305 RAMAC — or simply RAMAC — was the first computer to use a random-access disk drive. The progenitor of all hard disk drives created since, it made it possible for any computer user to quickly and easily store, access, alter and erase data without technical training or manual intervention.
Mar 2, 2020 · However, the long answer is that theoretical computer scientists do use a model with random access memory, in real practice: it's called the RAM (Random Access Machine) model.
