> Computer technicians should actively listen, have a positive attitude, and use logic when solving problems.
> The CompTIA A+ certification requires two exams: Core 1 (220-1101) and Core 2 (220-1102). Many people break into the IT field with this certification.
> IT staff must be proficient at searching for information on the internet, capturing files, and documenting technical information.
> Computers consist of hardware (the physical parts) and software (the operating system and applications).
> A technician needs to be able to identify important computer parts installed in a computer and as standalone parts: case, keyboard, mouse, motherboard, monitor, power supply, hard drive, optical drive, adapter, and memory.
> A technician needs to know the purposes of common peripherals used in the industry: printer, flatbed scanner with ADF, camera/webcam, microphone, and headset.

A+ CERTIFICATION EXAM TIPS
Get a good night’s rest the night before the exam.
Ensure that you are knowledgeable about and proficient with all of the terms and technologies listed in the official CompTIA A+ exam objectives. Some students study for a particular exam by going through the objectives one by one and reviewing the material as they go through.
Ensure that you can identify the basic parts of a computer and explain the purpose of each one. Ensure that you know the following parts: hard drive, optical drive, power supply, motherboard, and RAM.
Know common hardware so you will be familiar with future chapters that go into the details of installing, configuring, and troubleshooting these devices: printer, flatbed scanner, ADF, monitor, optical drive, mouse, keyboard, trackpad, drawing pad, camera/webcam, microphone, speakers, and headset.
Know the following safety procedures: disconnect power, remove jewelry, lifting techniques, and weight limitations.
Review the “Soft Skills” section at the end of the chapter. Make sure you know what open-ended questions are.
