- C)HT here means Hardware Technician & Operating Systems Technician, administered by Mile2, not any other credential sharing the acronym.
- Mile2 treats C)HT (hardware) and C)OST (operating systems) as two certifications taught in one course.
- Our 25 study topics are a union of published outline headings, not official weighted exam domains.
- The outline cites 100 multiple-choice questions, about two hours, and a 70% minimum, but allocation between exams is unclear.
What the C)HT Label Actually Means
The acronym "C)HT" is crowded. Several unrelated credentials in different fields use the same letters, and search results blend them together. This article covers exactly one: the Hardware Technician & Operating Systems Technician credential family published by Mile2. If you arrived looking for a healthcare, hypnotherapy, or any other "CHT" credential, none of what follows applies to you.
Mile2 writes the prefix with a closing parenthesis, as in C)HT, which is its house style for certification names. In Mile2's Terms and Conditions, C)HT (also written CHT) is identified as Certified Hardware Technician, and its companion, C)OST (COST), is identified as Certified Operating Systems Technician. On this site the combined label covers both credentials, because Mile2 teaches and describes them together. For other phrasings of the same question, see our explainers on what C)HT stands for and the C)HT meaning.
Who Governs and Administers It
Mile2 is the governing and administering body. Its materials describe the certification content, the learning platform, the policies, and the renewal programs. Everything on this page traces back to Mile2 public pages: the course outline page, the five-page Certified Hardware Technician & Certified Operating Systems Technician Web Outline, the public course listings, the self-study page, the Policies and Procedures document, and the renewal and FAQ pages. Public sources were last checked on October 9, 2026.
One limitation matters: protected lessons, workbooks, and actual examination content are not publicly retrievable. That means any claim about specific exam questions would be speculation. What we can describe reliably is the published topic list, the stated format, and the administrative rules.
Two Credentials, One Course
Mile2's self-study page describes two certifications in one course. The combined outline covers a hardware track and an operating-systems track. The outline also describes a five-day live class for each credential and 80 CEUs. Those are course measures, not examination time, so do not confuse "five days" with how long an exam sitting runs.
| Aspect | C)HT | C)OST |
|---|---|---|
| Full name | Certified Hardware Technician | Certified Operating Systems Technician |
| Focus | Physical components, peripherals, cabling, mobile devices, printers, procedures | Operating systems, Windows management, networking, virtualization, security |
| Published topics on this site | Domains 1 to 14 | Domains 15 to 25 |
| Administered by | Mile2 | Mile2 |
If you are weighing whether to pursue both at once, our C)HT worth-it analysis and requirements guide go deeper on qualification questions.
The Hardware Side: Domains 1 to 14
The 25 headings used on this site are the union of published, unweighted preparation topics. They are not an official exam-domain count, not a complete exam blueprint, and no official percentage weights are published in the sources. Domains 1 to 13 follow the detailed hardware chapters. Domain 14 keeps TCP/IP and Transport Protocols from the hardware summary without inventing a separate chapter for it. For the full breakdown, see our guide to all 25 content areas.
Domains 1 to 3: Troubleshooting, Motherboards and CPUs, Computer Power Supplies
Troubleshooting opens the hardware outline, which signals that methodical fault isolation is foundational rather than an afterthought.
- Expect a structured diagnostic approach applied to symptoms across later domains.
- Motherboards and CPUs cover the core platform that every other component plugs into.
- Computer Power Supplies is the detailed chapter name; the hardware summary uses the shorter alias "Power Supplies."
Domains 4 to 6: Memory, Computer Expansion, Physical Storage
These three domains cover the components that determine capacity and upgrade paths.
- Memory: types, installation, and compatibility with the platform.
- Computer Expansion: adding capability through expansion interfaces and cards.
- Physical Storage: drives and the media a machine boots from and keeps data on.
Domains 7 to 9: Input-Output Devices, Display Devices, Network Cables and Connectors
Peripherals and physical connectivity make up the next block.
- Input-Output Devices and Display Devices cover what users touch and see.
- Network Cables and Connectors is the physical-layer groundwork for the networking domains later in the outline.
Domains 10 to 14: Mobile Devices, Printers, Custom Computers, Operational Procedures, TCP/IP
The closing hardware block mixes device categories with professional practice.
- Mobile Devices appears in the detailed hardware outline but not the hardware summary.
- Printers and Multifunction Print Devices is its own chapter, a frequent real-world support task.
- Custom Computers lists Wi-Fi standards and wireless-encryption subsections.
- Operational Procedures covers how technicians work, not just what they work on.
- TCP/IP and Transport Protocols comes from the hardware summary, which includes it while omitting Mobile Devices.
The Operating Systems Side: Domains 15 to 25
Domains 15 to 25 follow the eleven detailed C)OST chapters. The progression moves from operating-system fundamentals through networking and into security.
Systems and Management
- Domain 15: Operating Systems establishes the platform concepts.
- Domain 16: Windows Management covers administering Windows environments day to day.
Networking
- Domain 17: Network Basics and Domain 18: Network Protocols build conceptual networking knowledge.
- Domain 19: Wireless Networking addresses wireless concepts.
- Domain 20: Windows Networking applies networking inside Windows environments.
Virtualization, Security and SOHO
- Domain 21: Virtualization and Cloud Computing covers hosted and virtual environments.
- Domain 22: Security Principles, Domain 23: Security Technologies, and Domain 24: Securing Devices and Data form a three-part security arc from concepts to tools to practice.
- Domain 25: SOHO Network Configurations ties networking and security together in the small office/home office setting.
Key Takeaway
Wireless content appears on both sides: Wi-Fi standards and encryption inside Custom Computers (hardware) and again in Wireless Networking (OS). Study the two together so the overlap reinforces rather than confuses.
Exam Format and What Is Unclear
The combined outline describes 100 multiple-choice questions, approximately two hours, and a 70% minimum grade. The catch is that its exam paragraph is singular, while the two credentials are separately named. The text does not unambiguously say whether those figures apply to each exam individually or to one combined sitting. We therefore do not infer an aggregate question count or duration, and you should confirm the details inside your Mile2 account before test day.
Other caveats from the sources:
- The outline is undated and publishes no C)HT/C)OST exam revision number.
- A legacy reference to CompTIA A+ 220-1002 appears in the material, but it does not establish the Mile2 exam version or any current A+ alignment. Do not assume the two are interchangeable.
- The course-outline page's "Exam Only / Purchase Exam Combo" link leads to an unrelated product (C)CSA). That page cannot be used to establish C)HT/C)OST exam identity or fees.
For more on the scoring side, read our passing score guide and the difficulty breakdown. No verified pass-rate data is published, which our pass rate article explains in more detail.
Registration, Testing and Policies
Testing is delivered through Mile2's online Learning Management System, accessed with a Mile2.com account. The May 26, 2026 Policies and Procedures document identifies the platform as LearnDash and lists several conditions:
- You need a Mile2.com account to reach the exam.
- Identification verification is required.
- You must accept Mile2's policies before testing.
- You may enter a certification exam without buying Mile2 training.
That last point matters for self-directed learners. Training is optional for exam entry, so a candidate with strong hands-on experience can prepare independently. Pricing specifics are covered in our certification cost breakdown, and scheduling in the exam dates guide. Note that no C)HT/C)OST exam fee is established by the sources reviewed here, so verify any figure directly with Mile2.
Three-Year Validity and Renewal
Credentials are valid for three years. Mile2's current Certification Renewal Program and Paths to Renewal pages describe alternative routes:
| Route | What it involves |
|---|---|
| CEU renewal | A standard 60-CEU cycle with documented activities, paid renewal, and an ethics attestation |
| Exam renewal | Passing the latest applicable certification exam |
The current FAQ lists USD 200 for the U.S. regional CEU renewal path. Eligible developing-region candidates may qualify for a lower price, and exam-based renewal may cost more.
Who This Credential Suits
No hiring statistics or salary figures are published in the sources, so we will not invent any. What the outline does make clear is the skill profile. The hardware domains map to bench repair, desktop support, and deskside technician work. The OS domains map to help desk, systems support, and small-network administration. Combined, the two credentials suit entry-level IT support roles that blend physical troubleshooting with operating-system and basic network skills.
Employers that run lean IT teams, such as managed service providers, schools, small businesses, and internal help desks, tend to value people who can handle both the machine and the software on it. For role ideas, see C)HT jobs, and for earnings context with appropriate caveats, the salary guide.
Sequencing Your Preparation
Because the outline moves from physical components to operating systems to security, a domain-ordered plan works well. Here is one way to schedule it, with the reasoning attached to each phase. Our full study guide adds technique.
Hardware foundations
- Start with Troubleshooting (Domain 1) because it frames every later diagnosis.
- Then cover Motherboards and CPUs, Computer Power Supplies, Memory, Computer Expansion, and Physical Storage.
Peripherals, devices, procedures
- Input-Output, Display, Network Cables and Connectors, Mobile Devices, Printers.
- Finish with Custom Computers, Operational Procedures, and TCP/IP, revisiting the wireless subsections.
Operating systems and networking
- Operating Systems and Windows Management first, then Network Basics, Network Protocols, Wireless Networking, and Windows Networking.
- Reuse your TCP/IP notes from Domain 14 here.
Cloud, security, SOHO, and timed practice
- Virtualization and Cloud Computing, then the three security domains, then SOHO Network Configurations as the capstone.
- Take timed multiple-choice sets on the practice test site to build stamina for a 100-question format.
Because the exam is multiple choice, practice with realistic questions is the best way to find weak spots. A one-page recap helps late in your schedule, so keep the C)HT cheat sheet handy, and use our practice questions to confirm which domains need another pass.
Frequently Asked Questions
It refers to Mile2's Certified Hardware Technician credential, taught alongside Certified Operating Systems Technician (C)OST) in one combined course. Other credentials share the acronym but are unrelated.
No. They are the union of published, unweighted preparation topics from Mile2's outlines. No official percentage weights are published, and the list is not an exhaustive exam blueprint.
The combined outline mentions 100 multiple-choice questions, roughly two hours, and a 70% minimum grade, but it does not clearly assign those figures to each separate exam. Confirm in your Mile2 account.
No. Mile2's May 2026 Policies and Procedures permit certification-exam entry without purchasing Mile2 training, though you still need a Mile2.com account, identification verification, and policy acceptance.
It is valid for three years. Mile2 describes a 60-CEU renewal route or renewal by passing the latest applicable exam, but source wording conflicts on deadlines, so check the current renewal pages directly. See also our C)HT certification overview.
