The Base of Binary Numbers • Decimal numbers function on a base 10 system. This means that each time you moved one digit to the left, the value increases by a multiple of ten. Ex. 1 is 10^0, 10 is 10^1, 100 is 10^2, ect. • Binary numbers differ from this because they use a base two system. • This means that the rightmost number is 1, the number to the left of that is 1 to the power of 2, and so on. Ex. 1 is 2^0, 2 is 2^1, 4 is 2^2, ect.

Numbers • Another thing that makes binary code different from decimal numbers is that binary code uses only two numerals, 1 and 0. • You can remember this because “bi” means two, like bicycle, and there are two numerals used in binary code.

Reading Binary Numbers • Binary numbers read from right to left, the exact opposite of decimal numbers. • As was stated earlier, binary code uses a base two, meaning that each number is greater than the number to the right of it by a power of two This can be seen here: …512, 256, 128, 64, 32, 16, 8, 4, 2, 1.

Reading Binary Numbers (cont.) • Reading binary numbers is basically like adding. You add the numbers that are marked by a 1. *Remember, you read binary code from left to right. • Since the smallest number in binary code is one, if the rightmost number is marked by a 1 we know to add one to the total, if it is marked by a 0, do not add one. • If the next number (2^1, or 2) is marked by a 1, add two, if it is marked by a 0, add nothing.

Reading Binary Numbers (cont.) • If the next number to the left (2^2, or 4) is marked by a 1, add four to the total. If it is marked by a 0, add nothing. • See a pattern? Each time we move one digit to the left the value is multiplied by two, starting with one and going to two, then four, and so on to infinity. • Also, we know whether or not to add a number to the total by whether or not it is marked with a 1. If it is marked with a zero instead, add nothing.

Writing binary numbers • Writing binary numbers is similar to reading them; it is just done in the opposite order. • When writing a binary number from a decimal number, chose the largest exponent of two that is equal to or smaller than your number. For example, if the number is 467, the largest exponent of two would be 256 or 2^8. • The exponent of two, in this case 8, tells you how many numbers will follow this original number.

Writing Binary Numbers (cont.) • After choosing the largest exponent of two possible, subtract that number from your decimal number. Ex. 467-256= 211 Put down a 1. • Now that your new number is 211, you need to find the largest exponent of two that is smaller than or equal to 211. • The next number down, 128, is small enough, so you mark it with a 1 and subtract it from 211. 211-128= 83

Writing Binary Numbers (cont.) • Now your number is 83, and you must find the next exponent of two that is still smaller than it, which in this case is also the next smallest number, 64. • Repeat as in the previous steps, marking with a 1 and subtracting from the previous number. • Your new number is 19, and the next smallest number is 32, which is too big, so you mark that spot with a 0.

Writing Binary Numbers (cont.) • The number after 32, which is 16, is small enough, so you subtract, and mark 16 with a 1. • The new number is 3, and the next two numbers, 8 and 4, are both two big, so you mark those spots with a zero. • Two is small enough, so you repeat marking and subtracting, and the new number is 1. • You subtract this from the final number, which is also 1, and mark with a one.

Viruses • A virus is a small piece of software that piggybacks on real programs. For example, a virus might attach itself to a program such as a spreadsheet program.

Worms • A worm is a small piece of software that uses computer networks and security holes to replicate itself. A copy of the worm scans the network for another machine that has a specific security hole. It copies itself to the new machine using the security hole, and then starts replicating from there, as well.

The Origins of Viruses • Computer viruses are called viruses because they share some of the traits of biological viruses. A computer virus passes from computer to computer like a biological virus passes from person to person

The Evolution of Viruses • As virus creators became more sophisticated, they learned new tricks. One important trick was the ability to load viruses into memory so they could keep running in the background as long as the computer remained on.
