What are the differences between binary signaling and digital signaling?
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.
What is a binary digit?
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.
What is the difference between binary code and extendible binary code?
There is no such thing as extendible (sic) binary code. However, there are two known variants: eXtendable Binary (XB) is a universal file format used for serialising binary trees. Extended Binary Coded Decimal Interchange Code (EBCDIC) was an 8-bit character encoding used by IBM in the 1960's. It's a non-standard encoding that was used by IBM prior to them switching to ASCII peripherals.
Number of all possible binary trees with 2 nodes is?
Two: 1. root and left child 2. root and right child
What is the most basic logical element of data?
The most basic logical element of data is the binary digit, or bit, which can represent the numeric value 0 (the bit is unset) or 1 (the bit is set), which can subsequently represent any opposing concept, such as true or false, yes or no, black or white, positive or negative, etc. However, computer systems do not permit the storage of a single bit because a single bit cannot be addressed in memory. Every memory address represents a group of bits known as a byte (8 bits), thus a boolean value (a value that has only two possible states, such as true or false) is typically composed of 8 bits where the binary value 00000000 (no set bits) is regarded as being false while any other combination of bits (a non-zero value) is regarded as being true. Typically the binary value 11111111 (which is decimal -1 in signed notation) is regarded as being true but any non-zero value is also regarded as being true. In order to conserve memory, programmers will often combine several boolean values into a single value, such that each individual bit represents something different. Thus a single byte can effectively store up to 8 individual boolean values. In order to determine the state of any one bit, the programmer simply tests the combined bits against the bit-value he's actually interested in. For instance, to test if bit 3 is set (the fourth least-significant digit, from the right), the programmer will logically AND the combined bits with the value 23, which is 00001000 in binary (8 decimal). If the result is non-zero then bit 1 is definitely set, otherwise it is not.
