How do PCs download and copy?

Personal computers (PCs) download data by establishing a connection to the internet and requesting files from remote servers using protocols like HTTP or FTP. The server sends the requested data in packets, which the PC receives and reassembles. Copying data on a PC involves creating a duplicate of files or folders within the storage system, which can be done using commands like "copy" or "paste." This process can also be performed on external devices, like USB drives, for data transfer.
