linker

  1. a synthetic double-stranded OLIGONUCLEOTIDE, containing a sequence for a specific RESTRICTION ENZYME. A linker is used to attach COHESIVE ENDS to a DNA MOLECULE that has BLUNT ENDS, for use, for example, in GENE CLONING.
  2. DNA contained in a NUCLEOSOME that is not directly complexed with the HISTONES.

Test and verification activities can be performed on the assembler hand code portions of a system, as well as object code verification of the C/C++ portions.
(56) A source code program usually consists of "English words and mathematical symbols that demonstrate the exact steps the computer should be performing." (57) A computer, however, cannot make use of the source code until it is first translated into machine-readable language, known as "object code." (58)
This point--that there is no practical difference between source and object code for these purposes--becomes even clearer when we consider the fundamental interchangeability of software and hardware.
To do so, Nanosoft must "reverse engineer" the HandyMan operating system's machine-readable object code into human-readable source code in order to find the string of code that allows application programs to work on the operating system.
But Quackenbush argues that there is no evidence that Microsoft object code - as opposed to its source code - is substantially similar to Sun's protected expression, which is embodied in the source.
The agreement calls for Motorola to provide Hitachi with FLEX Stack source code for Hitachi to compile and optimize into object code for both Windows(R) CE and paging applications.
The compiler is analogous to a textural-based C compiler in that it produces DSP object code directly.
They are working with channel partners to provide off-the-shelf applications and reusable object code for standard interactions.
Self-certified code is the pair of machine object code and machine-checkable formal proof.
After a software program has been created in source code, it is compiled or translated into a machine-readable language called object code. This code is nothing more than a long series of digits--zeros and ones--that is generally not readable by programmers.
"Pink is the first system software environment built from the bottom up with object-oriented technology," he says; it's an environment that will be "portable, adaptable, scalable and processor independent." NEXT, Cairo, and other would-be object environments really only offer a few top layers of object code and APIs on top of conventional procedural code; Pink was designed from the beginning to embody modern object technologies completely.
Each group of these binary digits is an instruction that causes the computer to perform a very basic task, such as "add" or "move." Programs in this format are said to be written in "machine language" or "object code."(6) Although it is possible for engineers to write software in machine language, the process is extraordinarily difficult and tedious, and virtually never done.(7) Instead, programs are written in easily understood, higher-level languages,(8) which are later translated into the object code that will operate the computer.(9) Software written in this format is known as source code.
