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.

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 byte is a single unit of digital information, made of of several bits of sequenced binary data.
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.
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.
Binary data refers to data that is represented using only two possible values, typically 0 and 1. This is the fundamental language of computers, where everything is ultimately represented in binary form. On the other hand, digital data is a broader term that encompasses any data that is stored or transmitted in discrete, non-continuous values. While binary data is a specific type of digital data, digital data can also include other numeral systems like decimal or hexadecimal.
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.

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.

it is a sequence of 1s and 0s. (binary) :)
