Little Computer 3, or LC-3, is a type of computer educational programming language, an assembly language, which is a type of low-level programming language.. It features a relatively simple instruction set, but can be used to write moderately complex assembly programs, and is a viable target for a C compiler.
An instruction set architecture (ISA) is an abstract model of a computer, also referred to as computer architecture.A realization of an ISA is called an implementation.An ISA permits multiple implementations that may vary in performance, physical size, and monetary cost (among other things); because the ISA serves as the interface between software and hardware.
The first was the CISC (Complex Instruction Set Computer), which had many different instructions. In the 1970s, however, places like IBM did research and found that many instructions in the set could be eliminated. The result was the RISC (Reduced Instruction Set Computer), an architecture that uses a smaller set of instructions.

Separate from the stack definition of a MISC architecture, is the MISC architecture being defined by the number of instructions supported. Typically a minimal instruction set computer is viewed as having 32 or fewer instructions, [1] [2] [3] where NOP, RESET, and CPUID type instructions are usually not counted by consensus due to their fundamental nature.
The machine language file is also a text file. Each line of this file is a 16-character string of binary digits that represents the encoding of each corresponding executable line of the source text file according to the specification described in the section "Instruction set architecture (ISA) and machine language".
