All data must be copied into the computer's main memory, specifically RAM (Random Access Memory), before it can be read by the CPU. The CPU accesses data from RAM because it provides fast, temporary storage that allows for quick retrieval and processing of information during computational tasks. This process involves transferring data from secondary storage (like hard drives or SSDs) into RAM, enabling the CPU to perform operations efficiently.
the right place on the hard disk has to be found, then the read/write head must be placed there, then the sector (a small part of the hard disk) is read or written, if it's read, the data is moved into the memory, maybe by the DMA (Direct Memory Access) Controller. Is it's a write operation, the data must first be given to the Hard Disc Controller.
Data must be moved into RAM before a computer can perform any actions on the data. The CPU can not directly read or write data that is stored in secondary storage devices, such as a hard drive without first having that data loaded into memory, usually through the assistance of a DMA controller and an IDE or SATA controller.
Programs are copied into the computer's memory (RAM) for the CPU to read and execute.
Disk Caching.
This means that Windows is unable to read the floppy disk. The floppy disk is likely damaged, and no data can be copied from it.
The Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS).

Sequential access is a method of data access used by tape drives, whereby data is written or read sequentially from the beginning to the end of the tape or until the desired data is found. Basically, in order to read data from anywhere on a tape, you must start at the beginning of the tape and read until you come to the "sought-after" data.
Absolutely not. Anyone can post say or do almost anything. If anything it is the exact Opposite. You must all ways validate sources and common sense on anything you hear read or watch.
In digital form, no one can read the documents without using a computer. This is more secure than handwritten documents, but can still be easily copied.
The computer screen is a device that displays the content of a file. This file is in Random Access Memory (RAM). Moreover, to process some data, you need the microprocessor. It can only work with data stored in its cache (local memory inside the microprocessor) and in RAM (central memory) That's why to view something on the screen, a program has to copy the data into a "buffer" that will be read by the screen.
It is for all intents and purposes impossible to stop a file from being copied. Once you have given another person access to a file, they can copy it as much as they like. You can only protect the contents of a Word document from being read. If it can be read, it can be copied.
