Computer Worms

A computer worm is a piece of software which can reproduce and spread itself. While not always harmful, computer worms often act like (and are often confused with) computer viruses. Questions about these types of programs belong here.

How does BCD differ from the straight binary number system?

To consider the difference between straight binary and BCD, the binary numbers need to be split up into 4 binary digits (bits) starting from the units.

In 4 bits there are 16 possible values from 0000 to 1111 (0 to 15).

In straight binary all of these possible combinations are used, thus:

4 bits can represent the decimal numbers 0-15

8 bits can represent the decimal numbers 0-255

12 bits can represent the decimal numbers 0-4095

16 bits can represent the decimal numbers 0-65535

etc

In arithmetic, all combinations of bits are used, thus:

0000 1001 + 0001 = 0000 1010

In BCD or Binary Coded Decimal, only the representations of the decimal numbers 0-9 are used (that is 0000 to 1001 in binary), and the 4-bits (nybbles) are read as decimal digits, thus:

4 bits can represent the decimal digits 0-9

8 bits can represent the decimal digits 0-99

12 bits can represent the decimal digits 0-999

16 bits can represent the decimal digits 0-9999

In arithmetic, only the representations of decimal numbers are used, thus:

0000 1001 + 0001 = 0001 0000

When BCD is used each half of a byte is read directly as a decimal digit.

BCD is obviously inefficient as storage (for large numbers) as each nybble is only holding 3/8 of the possible numbers, however, it is sometimes easier and quicker to work with decimal digits (for example when there is lots of display of counting numbers to do there is less binary to decimal conversion needing to be done).

What is pinger exe?

What is the problem with a computer virus?
