What are constants and variables?
|
Constants and variables represent memory locations that we reference in our program solutions.
Constants are objects that store specific data that can not be modified.
10 is an integer constant
4.5 is a floating point constant
"Side1" is a string constant
'a' is a character constant
Variables are memory locations that store values that can be modified.
double x1(1.0), x2(4.5), side1;
side1 = x2 - x1;
x1, x2 and side1 are examples of variables that can be modified.

The system clock is used to synchronize activity on the motherboard. The clock sends continuous pulses over the bus that different components use to control the pace of activity.
A motherboard can have several buses, including the system bus, the PCI express bus, the PCI bus, the AGP bus, and the outdated ISA bus.
The frequency of activity on a motheboard is measured in megahertz (MHz), or one million cycles per second. The processor operates at a much higher frequency than other components in the system, and its activity is measured in gigahertz (GHz), or one billion cycles per second.
