Solution:

• In computer programming, machine code is any low-level programming language, consisting of machine language instructions, which is used to control a computer’s central processing unit (CPU).
• Each instruction causes the CPU to perform a very specific task, such as a load, a store, a jump, or an arithmetic logic unit (ALU) operation on one or more units of data in the CPU’s registers or memory.
• Machine code is a strictly numerical language which is designed to run as fast as possible, and may be considered as the lowest-level representation of a compiled or assembled computer program or as a primitive and hardware-dependent programming language.
• The majority of practical programs today are written in higher-level languages or assembly language. The source code is then translated to executable machine code by utilities such as compilers, assemblers, and linkers, with the important exception of interpreted programs,which are not translated into machine code.
