The principle of RAM (Random Access Memory) is that
any location in memory can be accessed directly and in approximately the same amount of time, regardless of its physical location . This is in contrast to sequential access storage like tape, where accessing a specific piece of data requires reading through all the preceding data.
This "random access" capability is achieved through the use of an address bus. Each memory location has a unique address, and the CPU uses this address to directly access the desired data. The memory controller then retrieves the data from that specific location and makes it available to the CPU.
In simpler terms:You can jump directly to any piece of information stored in RAM without having to go through everything else first. This speed is crucial for the fast operation of a computer.
