Binary code

Binary Code 

Binary Code is a code for computers to mimic text and or computer instructions through a system of 0s and 1s which is involved with every computer system in the world.

And Gate

• The And gate is activated with the use of two ones, one or less ones will not work.

Or Gate

• The OR gate is activated if it has a one in the inputs if not it won't be active

Not Gate 

• The Not gate is activated with the opposite effect. For Example if it is one it will be off and it is 0 it will be on.

Numbers in Binary are represented using a series of zeros and ones (Zero being off and One being on). They are used in a four called a "Nibble" to help I will display so simple binary: 0001 = 1 0010 = 2 0100 = 4 1000 = 8, with these numbers you can go from 1 to 25 past 15 you have to use Bytes. With the small limit of numbers you can go up to 8 numbers and calling it 8 bit or a Byte. Also with Bytes the numbers double as they go up, For Example: 00010000 = 16 00100000 = 32 01000000 = 64 10000000 = 128. You can use these as sums for example 10100000 = 160.If you have a sum like 010 + 010 you carry the one over so it equals 100 instead of 020, however if you do not the space to but the 1 in the sum it causes an overflow in the equation. Becoming more complicated you can start to use letters in Binary Starting with A = 01000001 B = 0

1000010 and so on.

Hex

Hex is used as a simple form of binary. It is used a 16 Number System The first numbers 1-9 are used as numbers but 10-15 are represented as numbers; this can make it quite complicated because 9 + 9 instead of equalling 18 it equals 12  because 18 in the Hex system is represented by 12.

 

 ASCII

ASCII or American Standard Code For Information Interchange is based off the English alphabet has 128 specified characters. Which contains the English Alphabet upper case and lower case (52 Characters), The numbers 0-9, some basic Punctuation Symbols, Some Control Codes that originated from Teletype Machines and a blank space. This all equals to 127 but the 128th Character is of course Null or 00000000.
