What
3.1 Hardware page 26
Central processing unit (CPU), microprocessor, clock speed: for example, megahertz (MHz), gigahertz
(GHz), terahertz (THz)
• Primary storage: read-only memory (ROM), random-access memory (RAM)
• Secondary storage: optical, magnetic, flash memory: for example, USB (universal serial bus) flash drive
• Bit, byte, kilobyte (KB), megabyte (MB), gigabyte (GB), terabyte (TB), petabyte (PB), exabyte (EB),
zettabyte (ZB), yottabyte (YB)
• Character encoding: ASCII (Unicode and American Standard Code for Information Interchange)
Why
Understanding the specifications of a system requires a knowledge of the terms and what they correspond to.
How
When you can read the specs of a system and determine if it will meet the needs of the intended user.
