Computers-A-Journey-Through-Time 
                     Computers: A 
Journey Through 
The icommputer is a word derived from the word "compute", which 
means to calculate. Some people say that COMPUTER stands for 
Common Operating Machine Purposely Used for Technological and 
Educational Research.
1. COMPUTER = Arithmetical Logical Unit (ALU) +Control Unit (CU)
ALU: Arithmetic Logical Unit is used to carry out arithmetic and 
logical operation.
CU: Control unit is used to change the order of operations in response 
to stored information.
We are going to look at what is computer and how it is going to help 
us in different ways.
