  Binary numeral system - Wikipedia, the free encyclopedia
An ordered binary arrangement of the hexagrams of the I Ching, representing the decimal sequence from 0 to 63, and a method for generating the same, was developed by the Chinese scholar and philosopher Shao Yong in the 11th century.
A binary number can be represented by any sequence of bits (binary digits), which in turn may be represented by any mechanism capable of being in two mutually exclusive states.
Binary may be converted to and from hexadecimal somewhat more easily.

 Binary - Data Crystal
Binary or base 2 is the number system used natively by computers.
From this term, comes halfword (hword), for a unit of data half of the word size, double word (dword) for double the word size and quadruple word (qword) for eight times the word size.
It is useful to be able to convert between binary and decimal.

 About conversion between binary file and XML
The idea is not to have a binary representation of XML data, rather it is to have a XML representation of binary data.
While the data convertor would be a great working partner with the form editor, the converter at this stage is in a state of flux, so no attempt will be made to tightly integrate between the two now.
Binary data can also be edited by using both the converter and the form editor.

 Saugus.net: binary   (Site not responding. Last check: 2007-11-05)
The second is an offshoot of the first; data that is not meant to be intepreted through a common character set (like ASCII) is typically referred to as binary data.
Pure binary data is typically eight bit data, and transferring a binary file through ASCII channels without prior modification will result in corruption and loss of data.
Binary data can be turned into ASCII data via uucoding or bcoding.

 Formats : Writing Binary Data
Binary data stored in one order cannot be read by a computer that stores binary data in the other order.
The data are read correctly because both of the programs are run on the microcomputer using byte-reversed mode.
However, you cannot upload the data to a Hewlett-Packard 9000-series machine and read the data correctly because they are stored in a form native to the microcomputer but foreign to the Hewlett-Packard 9000.

Structured data refers to data that is tagged for its content, meaning, or use.
The answer is yes, and in this article I'll show you how to pass binary data as part of XML document and we will learn this by passing a signature image file associated with each bank account, as an example.
Binary data to base64 encoding and back can be done in many ways.

Although more businesses are beginning to consider data management a priority, many need to assess how their data is protected and take remedial actions to protect the integrity of their data.
Data can be backed up and stored in many ways, common ways are to a CD, tape or other hard drives.
All data on the hard drives should also be backed up at least weekly to tapes and archived for several months.

 RUMP Binary Data File Format
An implicit 1 bit is assumed to the left of bit 22 and the binary decimal point occurs between the implicit 1 and bit 22.
For example, 1920 data elements would be packed with 1024 elements in the first 11h record and 896 elements in the second.
Multiple spectra may be contained in a single data file with the parameters set in the first to be used for all subsequent spectra unless explicitly changed.

 Working with binary data
Binary data in the Tcl language is just strings consisting of characters with code points anywhere in the more limited range 0 to 255.
For binary data, there is also an internal representation as byte array objects (Tcl_NewByteArrayObj and friends) which stores binary data in a machine native representation, thus avoiding the extra encoding level of the UTF-8 string representation.
for binary data embedded in a script and simply processed as a unit, use base64 (examples include image files, files for foreign applications that you just want to write from the script, and blocks of cyphertext).

 Converting and Porting SPICE Binary Data Files
Computing environments that share the same binary file format may freely exchange SPICE binary data files as though the original files were produced in their environment.
If only the name of the input binary file is provided on the command line, TOXFR will generate a name for the output transfer file that has the same base name as the input binary file and an appropriate filename extension, based on the filename extension of the binary file.
In the first example, the name for the binary file produced is derived from the name of the transfer file, using the full base name and replacing the letter `x' in the file name extension with the letter `b', to indicate that the file is a binary file.

 What is binary? - A Word Definition From the Webopedia Computer Dictionary   (Site not responding. Last check: 2007-11-05)
Computers are based on the binary numbering system, which consists of just two unique numbers, 0 and 1.
This is why everything in computers seems to come in 8s (2 to the 3rd power), 64s (2 to the 6th power), 128s (2 to the 7th power), and 256s (2 to the 8th power).
This is Chapter 1 of Randall Hyde's book, "Art of Assembly Language." It describes the binary and hexadecimal numbering systems, binary data organization (bits, nibbles, bytes, words, and double words), signed and unsigned numbering systems, arithmetic, logical, shift, and rotate operations on binary values, bit fields and packed data, and the ASCII character set.

 Axis 2.0 - MTOM Guide-Sending Binary data with SOAP
Sending binary data by value is achieved by embedding opaque data (of course after some form of encoding) as element or attribute content of the XML component of data.
Sending binary data by reference is achieved by attaching pure binary data as external unparsed general entities outside of the XML document and then embedding reference URI's to those entities as elements or attribute values.
Therefore, the conceptual representation of such binary data is as if it were base64-encoded, using the canonical lexical form of XML Schema base64Binary datatype (see [XML Schema Part 2: Datatypes Second Edition] 3.2.16 base64Binary).

 Java Tip 117: Transfer binary data in an XML document - Java World
The advantage of this approach is it encodes three data bytes using four characters resulting in an encoded document that is 33 percent larger than the original binary document.
For many data sets, if you construct a histogram of each byte value's occurrence frequency within the data set, you get a very uneven distribution, where some bytes are used very frequently while others rarely or not at all.
For extremely large binary data sets, where encoding efficiency is most critical, you can calculate the mapping for each binary data stream before encoding.

 PostgreSQL: Documentation: Manuals: PostgreSQL 8.0: Binary Data Types
A binary string is a sequence of octets (or bytes).
Binary strings are distinguished from character strings by two characteristics: First, binary strings specifically allow storing octets of value zero and other "non-printable" octets (usually, octets outside the range 32 to 126).
In short, binary strings are appropriate for storing data that the programmer thinks of as "raw bytes", whereas character strings are appropriate for storing text.

 What is data? - A Word Definition From the Webopedia Computer Dictionary   (Site not responding. Last check: 2007-11-05)
Data can exist in a variety of forms -- as numbers or text on pieces of paper, as bits and bytes stored in electronic memory, or as facts stored in a person's mind.
For example, some applications make a distinction between data files (files that contain binary data) and text files (files that contain ASCII data).

 Chris Taylor : Binary data from a Structure
This technique also requires that the data be moved in two stages, from the structure to the byte[] an then from there to the stream, this could be costly for large structures.
Notice that it still requires that the data be moved in two stages and the use of the Marshal class carries the same security requirements as earlier.
This brings me to the second disadvantage, if the data is not written out in the exact order expected by the reader, the reader will either fail to read the structure or even worse, corrupt data.

 GrADS Gridded Data
The individual components of data descriptor files are discussed in detail in the section Elements of a Data Descriptor File.
The data descriptor specifies the data's grid dimensions, but it is up to the user to make sure that the binary data have been written to file in the proper order so GrADS will interpret them correctly.
It is helpful to think of a gridded binary data file as a sequence of "building blocks", where each building block is a horizonal grid of data varying in the X and Y dimensions.

 Howstuffworks "How Bits and Bytes Work"
The word bit is a shortening of the words "Binary digIT." Whereas decimal digits have 10 possible values ranging from 0 to 9, bits have only two possible values: 0 and 1.
Therefore, a binary number is composed of only 0s and 1s, like this: 1011.
How do you figure out what the value of the binary number 1011 is? You do it in the same way we did it above for 6357, but you use a base of 2 instead of a base of 10.

 Importing Binary Data
When you open a file containing binary data that is not of a format recognized by any other file reader available to your iTool, you must specify the format of the file before the iTool can read the data and place it into the data manager.
If the file contains binary data of a recognized format, such as TIFF or JPEG, the iTool will automatically choose the correct file reader to read the binary data.

 Send binary data in XML
If the data is “formatted” by the parser, you won’t be able to process the binary data correctly.
If you opt to embed the binary data in the XML document, you won’t have to pull the file from a remote source or decode it before using it.
Second, your binary data may contain the ]]> sequence, which would indicate the end of the nonparsed data to the XML parser even though it's not the end of the binary data—a messy situation.

 XML.com: XML, SOAP and Binary Data
Traditionally, two techniques for dealing with opaque data in XML have been used; "by value" or "by reference." The former is achieved by embedding opaque data as element or attribute content.
Referencing opaque data avoids some of the performance and bloat issues associated with base64/hex encoding, but introduces its own problem; because the data is external to the document, it isn't part of the message Infoset.
This suggests that the correct approach to handling opaque binary data in XML is that of encoding; that is, representing such data within the Infoset using the xs:base64Binary or xs:hexBinary types.

 Assigning Media Types to Binary Data in XML
Data sent and received over the Web typically uses the the MIME media type defined by [IETF RFC 2046], as the type system.
There is a desire to specify the media type information of such binary element content in a standard way in the [XML Information Set] and not just in the optimized serialization of that Infoset.
For example, a Web services application may be willing to indicate that binary data represents an image, but leaves it to a document to further specify whether it is "jpeg", "gif", etc. This meta-data is used to indicate the set of media types the binary data may have and is not required to be present.

If your data is saved in a proprietary binary format, these simple tasks are complicated beyond your wildest imagination.
The computer architecture on which your current Word binary runs will be obsolete, your today's computer will break down, and you will never be able to recover the information stored in your files.
This is why we have so many binary formats: Microsoft et al change them all the time to preserve the barrier to entry.

There is a desire to specify the content-type information of such binary element content in a standard way in the [XML Information Set] and not just in the optimized serialization of that Infoset.
For example, a Web services application may be willing to indicate that the binary data represents an image, but leaves it to a document instance to further specify whether it is "jpeg", or "gif".
This example illustrates that binary data with media type 'image/jpeg' is preferred but binary data with media type of 'image/tiff' is also allowed (with a lower preference).
