The word 'Wikipedia' represented in ASCII binary code, made up of 9 bytes (72 bits). A binary code represents text, computer processor instructions, or any other data using a two-symbol system. The two-symbol system used is often "0" and "1" from the binary number system. The binary code assigns a pattern of binary digits, also known as bits ...
This is a list of some binary codes that are (or have been) used to represent text as a sequence of binary digits "0" and "1". Fixed-width binary codes use a set number of bits to represent each character in the text, while in variable-width binary codes, the number of bits may vary from character to character.
Alan Turing is credited with being the first person to come up with a theory for software in 1935, which led to the two academic fields of computer science and software engineering. The first generation of software for early stored-program digital computers in the late 1940s had its instructions written directly in binary code , generally ...

nested block structure: code sequences and associated declarations could be grouped into blocks without having to be turned into separate, explicitly named procedures; lexical scoping: a block could have its own private variables, procedures and functions, invisible to code outside that block, that is, information hiding.

Diskette – storage of 0.5 MB per drive.
The first VAX, the VAX-11/780 had just come out in late 1977, and its floating point was highly regarded. VAX's floating-point formats differed from MBF only in that it had the sign in the most significant bit. [35] [36] However, seeking to market their chip to the broadest possible market, Kahan was asked to draw up specifications. [33]
Because the code generator uses an intermediate representation, the same code generator can be used for many different high-level languages. There are many possibilities for the intermediate representation. Three-address code, also known as a quadruple or quad is a common form, where there is an operator, two operands, and a result.
