A computer with a 1 Terabyte (TB) hard drive is overkill for most, but neither should you settle for an 80 Gigabyte (GB) drive.
Older machines usually have megabyte chips and newer ones have larger gigabyte chips installed.
Features include one gigabyte of RAM and a 16GB hard drive, as well as a 16GB SD Card and a 20GB EEE storage drive.
Computer memory chips are actually small circuit boards that contain a group of memory chips available in 32-bit or 64-bit bus widths called a SIMM or Single In-Line Memory Module containing megabyte (MB) or gigabyte (GB) chips.
In the years before MP3 technology, audio files on computers were extremely large, sometimes as big as a gigabyte or more per song.
