Pick the exam before you pick the book. Every one of the IT certification books for beginners on this page is written against a single exam code. A Security+ guide printed for SY0-701 won’t cover everything on SY0-801 once that version launches on November 17, 2026. The usual mistake runs the other way: someone buys a well-reviewed study guide, then finds out it targets an exam close to retirement or a job they do not actually want.
So this guide answers the first question as well. It maps six entry-level certifications (CompTIA Tech+, A+, Network+, Security+ and Linux+, plus Cisco’s CCST Networking) to the work each one prepares you for and names the one book we’d buy for each. Every pick links down to our full shelf guide for that exam, for when you want a practice-test book or a second opinion. Exam codes, editions and Amazon stock below were checked in October 2026.
Which IT certification should you take first?
For most people without an IT job yet, CompTIA A+ is the first certification to study, because it covers the hardware, operating system, networking and troubleshooting work a help desk does every day. None of these exams has a hard prerequisite (CompTIA and Cisco only recommend experience), so the choice comes down to where you are starting from and which job you want next. Start from that:
- You want a help desk or desktop support job: CompTIA A+. It is two exams, and it is the one CompTIA writes around the IT support specialist role.
- You’re not sure IT is for you yet: CompTIA Tech+. One exam instead of two, no experience expected, and a quick way to find out whether you enjoy the material.
- You already run your own home network: Network+ for a vendor-neutral start, or CCST Networking if you’re aiming at Cisco and the CCNA after it.
- You’re set on security: Security+, but only after you are comfortable with networking basics. ISC2’s Certified in Cybersecurity is the entry-level alternative, with no work experience required and a US$199 exam fee.
- You already live in a Linux terminal: Linux+. It is the hardest exam on this page for a true beginner, and the most useful if you are heading toward sysadmin or DevOps work.
Cloud is the one path this page does not cover with a pick. If you are going straight to cloud, the fundamentals exams are their own shelf, and we’ve ranked the books for Azure AZ-900 and AWS Cloud Practitioner CLF-C02 separately. Those exams assume you already know what a subnet, a VM and a user account are, so a cloud fundamentals cert works better as a second step than as a replacement for A+ or Network+.
Network+ against CCST is the closest call here, and it comes down to vendor. Network+ is vendor-neutral and broader. CCST Networking is a shorter exam (50 minutes against 90) with a lighter book, and it hands you straight into the Cisco track. Our CCNA vs Network+ comparison covers what happens one step further down each road.
Compare the beginner certification books side by side
Each row is the exam as it stands in late October 2026 and the one book we’d buy for it. Pages and publication dates come from the Amazon listing for the exact edition linked:
| Certification | Exam code | Status, October 2026 | Book we’d buy | Edition, pages, published |
|---|---|---|---|---|
| CompTIA A+ | 220-1201 and 220-1202 | Current since March 2025 | A+ Complete Study Guide | 6th, 1,920 (two volumes), July 2025 |
| CompTIA Network+ | N10-009 | Current, retirement estimated 2027 | Network+ Study Guide | 6th, 1,024, May 2024 |
| CompTIA Security+ | SY0-701, then SY0-801 | SY0-801 launches November 17, 2026 | Security+ SY0-801 Certification Guide | 4th, 696, September 2026 |
| Cisco CCST Networking | 100-150 | Current | CCST Networking Official Cert Guide | 1st, 608, late 2023 |
| CompTIA Linux+ | XK0-006 | Current since July 2025 | Linux+ Study Guide | 6th, 1,024, August 2025 |
| CompTIA Tech+ | FC0-U71 | Current since July 2024 | Tech+ Study Guide | 3rd, 768, October 2024 |
Five of the six come from Sybex or Cisco Press, and that is deliberate. Both publishers print the exam code on the cover and bundle online practice questions (Sybex gives a year of access after activation). For a beginner that matters more than the prose, because you’ll learn more from 200 wrong answers than from rereading a chapter. The Security+ row is the exception, and the reason is timing: Sybex’s SY0-801 edition is still a preorder, so the Packt guide is the only SY0-801 book from an established certification publisher you can buy in stock today.
1. CompTIA A+ Complete Study Guide, Sixth Edition
If you are starting from zero and want a support job, this is the book to buy first. Quentin Docter and Jon Buhagiar split it into two volumes, one per exam, so you can finish Core 1 (220-1201), sit it, and only then open the Core 2 (220-1202) volume instead of carrying 1,920 pages around at once.
The standout is what comes with it. Activation gives you a year of Sybex’s online environment with four custom practice exams, 200 electronic flashcards and a searchable glossary, which is enough question practice that you do not need a separate practice-test book on your first pass. The set shipped 113 days after the V15 exams launched, so every chapter maps to the current objectives rather than the retired 220-1101 and 220-1102 pair that older copies still advertise.
Where this falls short is pace. It is thorough to the point of slow, and if you already build PCs or fix family laptops you’ll skim half of Core 1. Skip it if you want a short review before an exam date that’s already booked; our full A+ book guide ranks the shorter review guide and the practice tests for that. It sat in the $25 to $45 range over the last few months, which is low for two volumes. Check the current price on Amazon.
2. CompTIA Network+ Study Guide, Sixth Edition
Network+ is the right first cert if you already understand what a router does and want the vendor-neutral version of everything behind it, and Todd Lammle and Jon Buhagiar’s guide is the one we’d start with. It is written against N10-009 and was in print 44 days before that exam launched in June 2024.
At 1,024 pages it reads like a networking textbook with the exam bolted on, which is what a beginner needs. Subnetting, routing, switching and wireless get explained from the ground up, then tested in the online question bank and flashcards that come with it. Lammle has written Cisco study material for years, and the explanations of routing behaviour carry that depth.
Timing is the weak point. CompTIA estimates N10-009 retires in 2027, so plan to sit it within about a year of buying this book. Check our Network+ book guide for a successor edition if you’re reading this late in 2027. Skip it if troubleshooting labs are your weak spot, because the book does not bundle any. It was the cheapest book on this page when we checked, in the $20 to $30 range. Check the current price on Amazon.
3. CompTIA Security+ SY0-801 Certification Guide, Fourth Edition
If you’ll sit Security+ in 2027, buy a book written for SY0-801, and right now Ian Neil’s Packt guide is the one you can actually get. CompTIA launches SY0-801 on November 17, 2026, which is 20 days after we checked, and the English SY0-701 exam keeps running until June 11, 2027.
It shipped in September 2026, 62 days ahead of the exam, and the cover promises three full-length mock exams, more than 500 practice questions and interactive flashcards. That is the practice volume you want for an exam with a 750 passing score and performance-based questions. We searched Amazon for SY0-801 titles on October 28: this was the only one from an established certification publisher in stock. Sybex’s tenth edition (Chapple and Seidl) is a preorder dated December 15, 2026, and most of the rest are independently published.
The weakness is track record: a brand-new edition has few reviews, and Packt’s table of contents wasn’t published when we checked. If you’re booking SY0-701 before June 2027, pass on it, because the Sybex SY0-701 Certification Kit is the stronger buy; our Security+ book guide compares both versions. Expect the $35 to $45 range. Check the current price on Amazon.
4. CCST Networking 100-150 Official Cert Guide
For anyone aiming at Cisco, the CCST Networking exam is the gentlest way in, and Russ White’s Official Cert Guide is the book we’d pair with it. Cisco lists the exam at US$125 and 50 minutes, calls it “a first step toward CCNA”, and sets no formal prerequisites. It is Cisco Press’s own guide for exam 100-150, so the chapter list follows Cisco’s topics: standards and concepts, addressing and subnetting, endpoints and media, infrastructure, diagnosing problems and security.
The 608 pages are about 40% lighter than the Network+ guide, and the Pearson Test Prep access adds more than 200 practice questions, over five hours of author video, flashcards and a study planner. That video is rare on this shelf, and it’s useful if reading a subnetting chapter cold doesn’t stick for you. The book also sets up the CCNA cleanly, since the same vocabulary carries straight into Cisco’s associate exam.
Pick Network+ instead when you do not plan to stay on the Cisco track, because Network+ is vendor-neutral and carries over to employers that don’t run Cisco gear. If you’re after a support job rather than networking, Cisco also runs CCST IT Support (100-140) with its own Official Cert Guide, and our CCST book guide covers all three CCST exams. The Networking guide sat in the $35 to $50 range. Check the current price on Amazon.
5. CompTIA Linux+ Study Guide, Sixth Edition
Linux+ is the right first cert only if you already use a Linux shell most days, and Richard Blum’s sixth edition is the only XK0-006 study guide from an established certification publisher. It shipped 42 days after the exam launched in July 2025. More than a year later, nothing from Pearson or McGraw Hill had joined it when we searched Amazon.
XK0-006 puts 17% of its weight on automation, orchestration and scripting, so treat the scripting chapters as exam material rather than optional reading at the back of the book. The online access adds a custom practice exam, 100 electronic flashcards and a glossary. That is thinner practice than the A+ set, which is why we’d pair it with a VM you can break rather than a second book.
Skip it as a very first cert if you’ve never opened a terminal, since CompTIA recommends a year of hands-on Linux experience and the performance-based questions assume it. Start with A+ or Tech+ and come back. Our Linux+ book guide pairs this with the command-line books that fill the practice gap. It was in the $30 to $40 range when we checked. Check the current price on Amazon.
6. CompTIA Tech+ Study Guide, Third Edition
Tech+ is the cert for someone who wants proof they can learn this material before committing to the two-exam A+, and Quentin Docter’s third edition is the Sybex guide written for FC0-U71. It is one exam of up to 70 multiple-choice questions in 60 minutes, and CompTIA says no prior experience is necessary. The book follows CompTIA’s six domains: tech concepts, infrastructure (the biggest at 24%), applications and software, software development, data and databases, and security. Software development and databases aren’t A+ topics at all, which is useful if you’re still deciding between support, development and data work.
The online package is generous for an entry exam, with 400 practice questions and 400 electronic flashcards according to the cover. Docter also co-wrote the A+ guide at the top of this list, so if Tech+ goes well, the move to A+ feels familiar rather than like starting over with a new author’s style.
Treat Tech+ as a stepping stone, not the credential you job-hunt with. Tech+ is CompTIA’s starting point, while A+ is the cert it aims at the IT support specialist job, so if you already know you want IT work, skip Tech+ and spend the time on A+. It was in the $30 to $40 range when we checked. Check the current price on Amazon.
Check the exam dates before you buy a certification book
A certification book ages with its exam code, not its print date, so the date that matters is when the exam behind it retires. CompTIA usually retires an exam version about three years after launch, and books for the replacement tend to appear in a window around the switch. On the six exams above, the gap between exam launch and the book we picked ran like this:
- Network+ N10-009: book printed 44 days before the exam launched, the earliest on this page.
- Security+ SY0-801: Packt shipped 62 days before launch; Sybex is dated 28 days after it.
- Linux+ XK0-006: 42 days after launch, and still the only publisher-backed guide.
- Tech+ FC0-U71: 91 days after launch.
- A+ 220-1201 and 220-1202: 113 days after launch, the longest wait on this page.
That spread is why a used copy from a marketplace seller is a gamble for a first cert. A+ books for 220-1101 and 220-1102 still sell, and they look almost identical to the current set, but CompTIA no longer lets anyone sit those exams. Run three checks on any copy before you pay for it:
- The exam code on the cover: it must match the current code on CompTIA’s certification pages or Cisco’s exam page. No code on the cover at all is a warning sign.
- The edition number: sixth for the Sybex A+, Network+ and Linux+ guides, third for Tech+, fourth for the Packt SY0-801 guide.
- The retirement date: if the exam retires before you can realistically sit it, wait for the next edition instead.
Some independently published Linux+ titles on Amazon put a year range like “2026-2028” in the name and list no edition number at all, which makes the second check impossible. For a first cert, the Sybex, Cisco Press and Packt guides above are the safer spend.
What to study after your first cert
Your first certification is only useful if the second one builds on it, so pick a lane and keep the next exam in the same family. These are the progressions we’d follow from each starting point:
- Started with A+ or Tech+: Network+ next, then Security+. That is the order CompTIA’s recommended-experience lines describe: Network+ lists A+, and SY0-701 lists Network+.
- Started with CCST Networking: go straight to the CCNA, using our ranked CCNA 200-301 books.
- Started with Security+ or ISC2 CC: CySA+ for blue-team work; our CySA+ book guide covers the current CS0-004 exam, and the ISC2 CC books page covers the lighter starting point.
- Started with Linux+: a hands-on vendor exam such as RHCSA, where everything is done in a live terminal rather than multiple choice.
If you only pick one book today, for most people it’s the A+ set at the top of this page. It covers the widest ground, and nothing in it goes to waste on the Network+ and Security+ books that follow. If you already know your lane, buy the book for that exam and book the exam date before you finish chapter three, because a fixed date is what turns a study guide into a pass.
