In computer terminology, a series of instructions that tells a computer what to do and how to do it is called what?

Introduction / Context:
This question tests understanding of a fundamental concept in computing. Computers follow sets of instructions written in programming languages in order to perform tasks. These sets of instructions have a specific name that appears throughout textbooks, user guides and exam questions. Recognising this name helps learners clearly distinguish between software, hardware and user input when thinking about how computers operate.

Given Data / Assumptions:

• The question refers to a series of instructions.
• These instructions tell a computer what to do and how to do it.
• Options include program, command, user response, processor and menu.
• We assume standard usage in introductory computer science and information technology courses.

Concept / Approach:
A program is a complete set of instructions written in a programming language that directs a computer to perform specific operations. Programs may be as small as a simple script or as large as an operating system. A command is typically a single instruction given to a program or operating system, not the entire series. User responses are inputs that users provide when asked questions by a program. The processor is hardware that executes instructions, and a menu is a user interface element listing available commands or options. Therefore, the correct term for a series of instructions that tells a computer what to do and how to do it is program.

Step-by-Step Solution:

Verification / Alternative check:
Introductory computer books define a program as an ordered set of instructions that cause the computer to perform a specific task. They distinguish it from data, which the program processes. Operating systems list installed programs that users can execute, and software development tools refer to writing, compiling and debugging programs. Commands are mentioned in the context of command line interfaces or menus as individual actions, not as full instruction sets. This widespread and consistent usage confirms that program is the correct term for the series of instructions described in the question.

Why Other Options Are Wrong:

• Command: Usually a single instruction or request to the operating system, not a complete series of instructions.
• User response: Data entered by the user when prompted, not the instructions that tell the computer what to do.
• Processor: The physical hardware component that executes instructions, not the instructions themselves.
• Menu: A list of choices or commands presented to the user in a graphical or text interface.

Common Pitfalls:
Some learners confuse programs with commands because both involve instructions. A helpful way to remember the difference is to think of commands as individual orders and programs as whole recipes. A recipe contains a series of steps, just as a program contains a sequence of instructions. When exam questions mention a series of instructions or a complete set of instructions, the word program is almost always intended. Keeping this analogy in mind can help you choose correctly even if similar options appear.

Final Answer:
A series of instructions that tells a computer what to do and how to do it is called a Program.
