Section 2 - Computer Component Basics
Most people are familiar with certain types of computers, such as the desktop and notebook computers that are commonly used in school, at home, and for business. But there are all types of computers that you probably haven't considered—devices that make our cars, washing machines, and cell phones work properly.
All computers are designed with similar common features. Engineers and technicians combine special digital logic circuits, part of what is called computer hardware. This hardware is needed for computer instructions (or software) to be processed or executed within the machine. Sequences of individual computer instructions make up a computer program, which is the set of commands defining what the computer does at any given time.
In this section, we will examine computer hardware, how computer hardware is organized, and how it works together.
In this section, you will learn to
- identify and evaluate PC components
- identify and purchase PC components
- describe how hardware components interact
- build a PC
- identify and evaluate peripherals
- define and evaluate green IT
- identify preventative maintenance steps needed for computers
