Binary is the base number system that computers understand. The processor reads and writes everything in binary. To understand binary is to understand how computers function. Please learn the contents below, a table that represents 1 to 8 in the binary base system. The answer is simple.
Computers use true or false statements for every component.
The processor constantly checks conditions, if somethings true, continue, false cancel. Its a rather simple concept to grasp. To make life easier on a programmer, a new number system was invented to ease the slack when dealing with binary numbers. This new system is called the Hex Decimal system. I cannot express how important it is to understand these tables.
