CompTIA A+ Core 1 Exam: Guide to Computing Infrastructure

Computer support work brings together practical hardware knowledge, networking fundamentals, and a calm approach to troubleshooting. CompTIA A+ Core 1 Exam: Guide to Computing Infrastructure organizes those subjects around the CompTIA A+ Core 1 (220-1001) exam objectives, with coverage ranging from laptop components and desktop upgrades to network connections, mobile devices, virtualization, cloud computing, and printers.

Across ten chapters, Jean Andrews, Joy Dark Shelton, and Jill West give aspiring IT support technicians a textbook-style route through the infrastructure topics in this edition. The emphasis is not only on identifying components, but also on selecting, installing, configuring, maintaining, and diagnosing them.

Build a foundation in computer hardware

The early chapters address working inside desktop and laptop computers, then turn to motherboards, processors, memory, power, cooling, and storage. Readers encounter tasks such as choosing components, upgrading memory, installing drives, and understanding BIOS/UEFI settings. Troubleshooting coverage ties component knowledge to common system and power problems.

Connect devices and make networks work

Later chapters cover peripheral devices, display systems, local networks, network infrastructure, and connectivity troubleshooting. The book also examines mobile-device configuration and security, accessories, synchronization, and the Internet of Things. This broad treatment helps readers see how individual devices fit into the systems people use at home and at work.

Explore virtualization, cloud services, and printers

The final chapter brings together client-side virtualization, cloud-computing concepts, and printer technologies. It covers printer setup, sharing, maintenance, and fault diagnosis alongside the virtualization and cloud topics listed in the exam objectives.

A practical study reference for Core 1

Its chapter organization and objective-to-chapter mapping make the book useful for learners who want to connect exam topics with the underlying IT support concepts. It may also suit readers seeking a broad introduction to computer infrastructure, from hardware installation through network and device troubleshooting.

Edition note: This is the tenth edition, aligned to the CompTIA A+ Core 1 (220-1001) objectives identified in the book.
