FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Data stored in primary memory can be directly accessed by the CPU, which cannot be accessed in secondary memory. Primary memory is lost during a power outage, while secondary memory saves the data. Primary memory is volatile, while secondary memory is non-volatile.

Detailed explanation-2: -Primary storage (also known as main memory, internal memory, or prime memory), often referred to simply as memory, is the only one directly accessible to the CPU. The CPU continuously reads instructions stored there and executes them as required.

Detailed explanation-3: -Random Access Memory, or RAM, is the primary storage of a computer–the hardware where the operating system (OS), application programs and data in current use are kept so they can be quickly reached by the device’s processor.

Detailed explanation-4: -Solid state drives (SSD for short) are the fastest type of storage drive, recording data on solid state NAND chips as opposed to the spinning platters inside a hard drive. This makes SSDs much faster than hard drives, although each GB of storage capacity will cost you more.

Detailed explanation-5: -Primary memory accessing data is quicker because of internal memory, and the processor uses the data bus to access primary memory data. The primary memory is normally volatile in nature, meaning that the data is not stored in the primary memory until it is saved.
