CPU usage: the percentage of time a central processing unit (CPU) is working. data transfer rate: the maximum speed at which data can be transmitted between two nodes on a network; usually measured in megabits per second (Mbps). external SATA(eSATA): fast transfer port, allows you to easily add an external hard drive for more storage space. express card: a circuit board with specific functions that augment the computer's basic functions and provide connections to other devices; examples include the sound card and the video card.
