Study Notes
Introduction
- Like other computer users, students have likely used computers for tasks like gaming, email, and spreadsheet programs.
- This text transitions from end-user to IT support technician, focusing on personal computer support.
- Prior computer experience is assumed, such as starting or loading software.
- A+ certification is the industry standard for IT support technicians; this text prepares for CompTIA A+ exams (220-1101 Core 1 and 220-1102 Core 2).
Exam Tip
- The text will highlight A+ Core 1 and Core 2 exam objectives, shown in teal and orange respectively, throughout each module or appendix.
- Students should review the objective grid for each completed module or appendix to solidify their understanding of exam topics.
Exploring a Desktop Computer
- Core 1 Objectives 1.1, 2.8, 3.1, 3.2, 3.3, 3.4, 3.5 are covered.
- Students need to learn how to disassemble and reassemble a desktop computer, and understand safety procedures.
- Safety precautions found in the appendix ("Safety Procedures and Environmental Concerns") should be followed carefully when working on a computer.
- Computer components are listed and described in the text, and further details about each component will be discussed later in the book.
- Computer disassembly should be done carefully; it can be a learning experience or an expensive mistake!
Protecting Yourself and the Equipment
- Core1 Objectives 1.1 and 3.4 are covered.
- Personal safety and equipment protection are vital when working inside a computer.
- Loose jewelry should be removed to prevent entanglement with the wires.
- Be cautious of sharp edges in computer cases.
