What This Credential Actually Is
The Hardware Technician & Operating Systems Technician credential, written C)HT on this site, is a Mile2 certification aimed at people who build, repair, configure and support desktop-class computing environments. It sits at the practical, hands-on end of the IT certification spectrum. The material walks from the screwdriver level (motherboards, power supplies, memory, drives, cables, printers) up through installing and managing operating systems, networking, virtualization, and basic security.
If you have landed here from a search for a definition, our explainers on what C)HT certification is and what C)HT stands for cover the naming basics. This article goes deeper on the actual content, the delivery mechanics and the places where Mile2's own published materials are ambiguous, because those ambiguities matter when you plan your preparation.
Two Credentials, One Course: Reading Mile2's Materials Correctly
The first thing to understand is that Mile2's own paperwork treats this as two credentials. Its Terms and Conditions identify C)HT as the Certified Hardware Technician and C)OST as the Certified Operating Systems Technician. Its self-study page describes two certifications delivered in one course. The published course outline is titled for both, and the live class format described in the outline is five days for each credential.
This site covers both together under one heading, which is why the content below spans 25 preparation topics rather than a hardware-only list. Those 25 headings are the union of everything Mile2 publishes in its outline documents. They are preparation topics, not an official count of exam domains, and they are not an exhaustive exam blueprint. No official percentage weights are published in the sources reviewed, so any article that quotes "Domain 7 is 12% of the exam" for this credential is inventing a number.
For a domain-by-domain walkthrough, see our complete guide to all 25 C)HT content areas. Below is a compact view of how the topics split.
| Track | Topics in this site's list | Source basis |
|---|---|---|
| Hardware (C)HT) | Domains 1-13, plus TCP/IP in Domain 14 | Detailed hardware chapters, with TCP/IP carried over from the hardware summary |
| Operating systems (C)OST) | Domains 15-25 | Eleven detailed operating systems chapters |
The Hardware Side: Domains 1-14
The hardware portion opens with Troubleshooting, and that placement is deliberate. Troubleshooting methodology is the thread that runs through every later hardware domain. Expect scenario-style thinking: a symptom, a set of plausible causes, and a need to pick the logical next step rather than recite a definition.
Core platform components
Domains 2-4: Motherboards and CPUs, Computer Power Supplies, Memory
These three domains cover the inside of the case. Candidates should be able to match components to each other and to a use case.
- Motherboards and CPUs: how boards and processors are matched, and what the board exposes to the rest of the system.
- Computer Power Supplies: the outline summary calls this topic Power Supplies, but the detailed chapter title is Computer Power Supplies. Treat them as the same subject.
- Memory: the types, installation and compatibility reasoning a technician uses at the bench.
Expansion, storage and peripherals
Domains 5-8: Expansion, Storage, Input-Output, Display
This block is about everything that attaches to the platform.
- Computer Expansion: adding capability through expansion hardware and interfaces.
- Physical Storage: drive technologies and how they are installed and configured.
- Input-Output Devices: the peripherals users touch every day.
- Display Devices: monitors and display technologies.
Cabling, mobility, printing and build work
Domains 9-13: Network Cables and Connectors through Operational Procedures
Network Cables and Connectors bridges hardware and networking. Mobile Devices, Printers and Multifunction Print Devices, Custom Computers and Operational Procedures round out the detailed hardware chapters.
- Custom Computers is more than assembly. The chapter outline lists Wi-Fi standards and wireless-encryption subsections, so do not skip it assuming it is only about picking parts.
- Operational Procedures covers the professional side of technician work, the habits and processes that separate a reliable technician from a lucky one.
- Printers and Multifunction Print Devices earns its own domain. Printer support is a perennial source of real-world tickets, and the outline treats it accordingly.
The Domain 14 wrinkle
Mile2's two hardware descriptions do not match exactly. The hardware summary includes TCP/IP but omits Mobile Devices, while the detailed hardware chapter list includes Mobile Devices and has no standalone TCP/IP chapter. This site's Domain 14, TCP/IP and Transport Protocols, preserves the summary's TCP/IP coverage without inventing a "Chapter 14." The practical advice: study both Mobile Devices and TCP/IP. Preparing for the union of the two lists costs a little extra time and protects you from either version of the outline.
The Operating Systems Side: Domains 15-25
The operating systems portion follows eleven detailed chapters. It starts with Operating Systems and Windows Management, then moves into networking, then security, then small-office configuration.
Domains 15-16: Operating Systems and Windows Management
The foundation. Candidates should understand how operating systems are installed, configured, maintained and administered, with Windows management tasks given their own domain. Expect to know where administrative tools live and what each one is for.
Domains 17-20: Network Basics, Network Protocols, Wireless Networking, Windows Networking
Four domains devoted to connectivity. Note the overlap with Domain 14 and Domain 9: cabling, TCP/IP and wireless ideas recur across the hardware and operating systems tracks. Studying them once is not enough; revisit them from the operating systems angle.
Domains 21-25: Virtualization, Security, and SOHO Networks
- Virtualization and Cloud Computing: modern support work routinely touches virtual machines and hosted services.
- Security Principles, Security Technologies, and Securing Devices and Data: three consecutive security domains, moving from concepts to tools to applied practice.
- SOHO Network Configurations: the capstone, where small-office and home-office networking comes together.
Key Takeaway
The security block (Domains 22-24) and the SOHO capstone (Domain 25) reward integration. Practice explaining how a firewall setting, a device policy and a router configuration interact, not just defining each in isolation.
For a sense of how demanding this breadth is, read how hard the C)HT exam is.
Exam Format, Delivery and What the Sources Leave Open
Here is what Mile2's combined outline actually states: 100 multiple-choice questions, approximately two hours, and a 70% minimum grade. Here is the catch: the outline's exam description is a single paragraph attached to two separately named credentials, and it does not clearly say whether those figures apply to each exam individually or to some combined arrangement. This site does not infer an aggregate question count or total duration, and you should be wary of any source that does.
Other numbers in the outline are course measures, not exam measures. The five-day live class for each credential and the 80 CEUs describe the training course. They are not exam time.
Two further cautions on exam identity:
- The outline publishes no exam revision number. Its mention of the legacy CompTIA A+ 220-1002 reference does not establish which Mile2 exam version you will sit or whether it aligns to any current A+ objectives.
- The course-outline page's "Exam Only/Purchase Exam Combo" link leads to a product for a different Mile2 credential (C)CSA). That product cannot be used to establish this credential's exam identity or fees.
Question style is multiple-choice, so practice should focus on recognition under time pressure and on scenario reasoning. A realistic way to rehearse is a timed practice session on our main practice test site, which lets you check whether your pacing holds across a long run of questions.
Registration Mechanics Through Mile2's Learning Management System
Testing is delivered online through Mile2's Learning Management System, accessed with a Mile2.com account. Mile2's Policies and Procedures document (dated May 26, 2026) identifies LearnDash as the platform and sets out several requirements:
- Create or use a Mile2.com account.
- Complete identification verification.
- Accept the published policies.
- Sit the exam in the online environment.
One genuinely useful policy detail: Mile2 permits certification-exam entry without buying Mile2 training. If you already have hands-on experience or have studied through other means, the policy does not force you to purchase the course first. Our C)HT requirements article covers eligibility questions in more depth, and C)HT exam dates explains scheduling.
On pricing: the sources reviewed do not establish an exam fee for this credential, and the only exam-combo link on the course page points at an unrelated product. Treat any specific exam price you see quoted elsewhere with suspicion until you can see it in your own account.
Three-Year Validity and the Renewal Maze
Mile2 credentials are valid for three years. The current renewal program describes alternative routes rather than a single required path:
| Renewal route | What it involves |
|---|---|
| CEU route | A standard 60-CEU cycle with documented activities, paid renewal and an ethics attestation |
| Exam route | Passing the latest applicable certification exam |
The current FAQ lists USD 200 for the U.S. regional CEU renewal path. Candidates in eligible developing regions may qualify for a lower price, and exam-based renewal may cost more.
Where Mile2's own documents disagree
Candidates should know that the renewal sources do not tell a perfectly consistent story:
- The undated course outline lists both an exam retake and 20 annual CEUs as requirements, while the renewal pages describe the routes as alternatives.
- The May 2026 Policies and Procedures document, on page 13, requires the CEU/recertification route within seven days of expiry and a full exam without CEUs afterward. On page 22, it retains annual-CEU wording and says a full-price retake may be required after seven days.
Sequencing the 25 Topics Over Your Prep Weeks
Rather than a generic schedule, sequence by dependency. Troubleshooting comes first because it frames everything else, hardware precedes operating systems because OS installation and management assume you know what is underneath, and networking appears twice, so it benefits from a deliberate second pass. This is a sample six-week shape; compress or stretch it to your own timeline, and see the C)HT study guide for a fuller method.
Troubleshooting, Motherboards and CPUs, Power Supplies, Memory
- Learn the troubleshooting sequence first, then apply it to each component domain
- Match components to each other for compatibility questions
Expansion, Storage, Input-Output, Display, Network Cables and Connectors
- Focus on interfaces and connectors that candidates commonly confuse
- Start a running list of connector-to-use-case pairs
Mobile Devices, Printers, Custom Computers, Operational Procedures, TCP/IP
- Cover both Mobile Devices and TCP/IP to be safe against either outline version
- Review the Wi-Fi standards and wireless-encryption material in Custom Computers
Operating Systems, Windows Management, Network Basics, Network Protocols
- Spend hands-on time in the administrative tools
- Revisit TCP/IP from the operating systems side
Wireless Networking, Windows Networking, Virtualization and Cloud Computing, Security Principles
- Connect wireless concepts back to the hardware chapter
- Build a small virtual machine lab if you can
Security Technologies, Securing Devices and Data, SOHO Network Configurations, full review
- Treat SOHO as the integration exercise
- Finish with timed mixed-domain practice

Where This Credential Fits in Your Career
The skills in this outline map to entry-level and early-career support roles: help desk and desktop support, field service and repair work, bench technician positions, and small-office IT administration. The SOHO and Windows-management emphasis suits environments where one person handles everything from a failed power supply to a misconfigured router.
The sources reviewed do not publish salary figures for this credential, so none are quoted here. For discussion of earning potential and value, see the C)HT salary guide, the analysis of whether the certification is worth it, and our overview of C)HT jobs. If you are weighing a structured course against self-study, the C)HT training page covers the options, keeping in mind Mile2's policy that exam entry does not require buying its training.
