Detailed explanation-1: -RAM is a temporary memory bank where your computer stores data it needs to retrieve quickly. RAM keeps data easily accessible so your processor can quickly find it without having to go into long-term storage to complete immediate processing tasks.
Detailed explanation-2: -RAM is a temporary data storage domain, whereas ROM serves as a semi-permanent storage domain. If RAM is likened to notebooks or memo pads, then ROM is comparable to dictionaries and textbooks.
Detailed explanation-3: -Random-access devices include hard drives, CD (compact disc) writers, and DVD (digital versatile disc) RAM (random-access memory) devices. The hard drive typically has a storage capacity of 20 gigabytes (GB) and a data transfer rate of over 10 megabytes (MB) per second.
Detailed explanation-4: -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.
