Expert Solution

Step 1

Little man Computer:

Little Man Computer (LMC) is a simple computer architecture and a corresponding assembly language used to teach the basics of computer architecture and programming. It was first described by Dr. Stuart Madnick in 1965 as a teaching tool for undergraduate students.
The LMC is a theoretical computer system that consists of a single accumulator register, a small amount of memory, and a set of instructions for performing arithmetic and data manipulation. It is designed to be easy to understand and use, and is used to teach the fundamental concepts of computer architecture, including memory, registers, and instruction sets.
The LMC assembly language consists of a small set of mnemonic instructions, such as LOAD, STORE, ADD, SUBTRACT, and HALT, that are used to perform simple operations on data stored in memory. Programs written in the LMC assembly language can be executed on a simulator, which simulates the behavior of the LMC architecture.
The simplicity of the LMC makes it an effective teaching tool for introducing students to the basics of computer architecture and programming. By learning to program the LMC, students can gain a deeper understanding of how computers work and develop the skills they need to write programs for more complex computer systems.
