Describe the five major components and architecture of a computer of a computer and the function of each component (Do not just list these components).
Describe five input and five output devices (Please be sure to describe and not just list the devices)
Some of the adverse health effects of computers include repetitive stress injuries, eyestrain and headache, and back and neck pains. We also consider the effects of electromagnetic fields and noise. Provide five ways to avoid repetitive stress injuries after exploring the websites below:

The Five Major Components and Architecture of a Computer
The architecture of a computer, often referred to as the Von Neumann architecture, is built around a central processing unit (CPU) that executes instructions retrieved from memory. This fundamental design is composed of five major functional units that work in concert to process information.
-
Central Processing Unit (CPU):
- Description: Often called the “brain” of the computer, the CPU is responsible for executing instructions, performing arithmetic operations, logical comparisons, and controlling the flow of data. It consists of two main sub-components: the Arithmetic Logic Unit (ALU) and the Control Unit (CU).
- Function:
- Arithmetic Logic Unit (ALU): Performs all arithmetic calculations (addition, subtraction, multiplication, division) and logical operations (AND, OR, NOT, comparisons).
- Control Unit (CU): Manages and coordinates all the operations of the computer. It fetches instructions from memory, decodes them, and then directs the other components of the CPU to perform the necessary operations, ensuring that data is moved and processed correctly. It acts like an orchestra conductor.
