Understanding Computer Hardware and Software

Computers are made up of two main parts: hardware and software. Understanding the difference is key to knowing how a computer works.

Computer Hardware refers to the physical components of a computer system. These are the parts you can see and touch. Hardware is essential for the computer to function and perform tasks.

Examples of computer hardware include:

• The Central Processing Unit (CPU)
• Memory (RAM)
• Storage devices (Hard drive, SSD)
• Input devices (Keyboard, Mouse, Scanner)
• Output devices (Monitor, Printer, Speakers)
• Motherboard
• Graphics Card

Computer Software, on the other hand, is a set of instructions, data, or programs that tell the hardware what to do and how to do it. Software is intangible; you cannot physically touch it.

Examples of computer software include:

• Operating Systems (Windows, macOS, Linux)
• Application Software (Word processors, Browsers, Games)
• Utility Software (Antivirus programs, Disk cleaners)

Analyzing the Options

Let's look at each option provided in the question to determine if it is hardware or software.

• Mouse: A mouse is a physical device used to interact with items on a computer screen. It is an input device, which is a type of computer hardware.
• Monitor: A monitor is a screen that displays output from the computer. It is an output device, which is a type of computer hardware.
• Keyboard: A keyboard is a physical device used to input text and commands into a computer. It is an input device, which is a type of computer hardware.
• Antivirus: Antivirus is a program designed to detect, prevent, and remove malicious software like viruses. It is a type of utility software, not a physical component.

Identifying What is NOT Computer Hardware

Based on the analysis:

• Mouse is hardware.
• Monitor is hardware.
• Keyboard is hardware.
• Antivirus is software.

The question asks which of the following is NOT a computer hardware. The item that is not hardware is Antivirus, because it is software.
