About this chapter
What this chapter covers
Mobile devices are laptops, tablets and smartphones. This chapter covers what is inside them, how to swap parts safely, what you can connect to them and how to set them up for networks and work.
It follows the first domain of the CompTIA A+ Core 1 220-1201 outline. There are three outline topics, and they are covered by five pages.
How the topics fit together
The pages move from the hardware outward to the network and the organisation.
- Hardware and monitoring names the parts and the signs of wear.
- Replacement techniques gives the safe order of work.
- Accessories and connections matches add on devices to the ports and radios that join them.
- Network settings covers the radios and the virtual private network (VPN).
- Email, sync and management covers accounts, apps and company control.
Scenario questions often mix topics, such as a phone that will not sync because airplane mode is on, so learn how the settings relate to each other.
How to use these pages
Each topic page has the same shape, so you can skim for what you need.
- What it is: the idea in plain words.
- How it works: the mechanism, with diagrams and tables.
- What to remember for the exam: the facts to memorise.
- Common mistakes: the classic traps.
- Check yourself: three questions to test your understanding.
Read the pages in order the first time. Later, use the exam facts and the common mistakes to revise.
