Binary refers to a system which may have one of two states. In computer science the binary numbering system is used where stored and communicated values are represented by 0 and 1. A digital signaling system would be based on an underlying stream of binary numbers so in most cases the two would be used interchangeably. If "binary signaling" where to be taken literally however it would describe a signaling system which communicates two possible states. The flag on a mailbox is a binary communication system, when the flag is up it signals that mail is available for pickup, when it is down there is nothing in the mailbox.

Digital
A byte is a single unit of digital information, made of of several bits of sequenced binary data.
An analog signal has a sine wave form and a binary signal has a block "wave" form. The binary signal is either on or off ("up" or "down"), and never anything in between. analog: http://img99.imageshack.us/img99/7723sineuk6.jpg binary: http://img154.imageshack.us/img154/1894binarypb6.png
A synchronous or asynchronous stream of signal consisting only of zero(no voltage) and one(position voltage) is called binary data stream. They may be bytestream, wordstream and so on. Sending unique binary pulses periodically create a binary digital signal. For example, you want to pass the number 346F5A through binary digital signal it will be 001101000110111101011010 Break it 0011-0100-0110-1111-0101-1010 you will find the binary equivalents of each digit. This example is very simple. Usually complex form of data are sent to and fro through data lines, be it the SATA cable of your hard drive, the USB port or the internet.
only difference is that binary is only consists of 0 and 1 bits,where as digital means it may either contain binary bits (0,1), or contain the numeric digit (0-9), mainely digital means just the number between 0 to 9
Digital Data is data that is stored in binary, and a Digital Device is any device that works with binary data
digital signals (usually binary coded) can include extra information that can be used for error detection or even correction. this allows recovery of the original signal, either by requesting retransmission or by directly correcting the error. analog signals can't include any extra information needed for this purpose. it is impossible to distinguish an error from the original data.
analog signals are continuous but digital signals are discreet. Digital signals have only binary value like zero(off state) or one(on state).
All electronic devices use digital communications, which is binary.
Digital
It will be asumed that you are refering to the binary number system, which is used in computers and digital devices. A binary number is always either 0 or 1. This is also commonly refered to as "low" or "high". This is in contrast to the decimal number system, where the numbers can vary between 0,1,2,3,4,5,6,7,8 or 9.
It already has; binary.
Everything "digital" or that is computer based.
digital
it is a sequence of 1s and 0s. (binary) :)
