9. CPU
 Central Processing Unit
 The Brain of the computer
 Measured in MHz (Megahertz) and GHz (Gigahertz)
Hertz = Cycles Per Second
Mega = 1,000,000

 Flexible
Operating System and a program loaded
into the system memory. When a system
run low on a available memory, the
computer will run more slowly

11. MEMORY MEASURED IN
Based on bit – 0 or 1 On/Off
Byte = 8 bits
K = Kilobyte = 1000
MB = Megabyte = 1,000,000
GB = Gigabyte = 1,000,000,000
TB = Terabyte = 1,000,000,000,000
PB = Petabyte = 1,000,000,000,000,000
