Older machines usually have megabyte chips and newer ones have larger gigabyte chips installed.
To break that down into simpler terms, one megabyte of space will hold one million bytes or characters.
Broadband connections provide high data transfer speeds up to 1 Mbps (megabyte per second), about 50 times the speed of dial-up.
Instead of a 5 megabyte MP3 file, the same song is orchestrated through a 10 kilobyte MIDI.
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.
