Preparing for the Computing and Information Technology DSST? Before you spend hours memorizing computer terminology or working through random practice questions, it helps to know exactly what the exam covers and how the test is structured.
The Computing and Information Technology DSST is a multiple-choice exam covering a broad introduction to computing and information technology. Its topics include computer hardware, operating systems, application software, networking, software development, data management, privacy, intellectual property, artificial intelligence, and the social impact of technology.
The exam contains 100 questions and allows two hours for completion. The current ACE recommendation lists 3 semester hours of lower-division baccalaureate credit for candidates scoring 400 or higher. However, your college or university decides whether it accepts the exam and how the credit applies to your degree.
This guide explains the exam topics, content weights, study strategy, passing score, college-credit questions, cost, registration, and practical 7-day and 14-day preparation plans.
What Is the Computing and Information Technology DSST?
The Computing and Information Technology DSST is a college-level credit-by-examination test designed to measure knowledge comparable to that covered in an introductory computing and information technology course.
It is broader than a programming exam.
You may encounter questions about:
- Computer hardware
- Operating systems
- Application software
- Databases and data management
- Computer networks
- Internet technologies
- Software development
- Software licensing
- Privacy and security
- Intellectual property
- Telecommunications
- Artificial intelligence
- Technology history
- Globalization
The official DSST description specifically identifies hardware, software licensing and development tools, development life cycles, data management, connectivity, privacy concerns, intellectual property, network etiquette, telecommunications law, artificial intelligence, and globalization among the areas tested.
That broad scope is important when planning your preparation.
For example, someone who knows Python well may still need to review computer architecture, databases, privacy, or technology history. Likewise, someone with years of general computer experience may already know much of the material without being an experienced programmer.

What Topics Are on the Computing and Information Technology DSST?
The official DSST content outline divides the exam into six major areas.
1. Computer Organization and Hardware — 20%
This section covers the physical and foundational components of computing systems.
Important concepts include:
- CPU
- ALU
- Fetch-execute cycle
- RAM
- ROM
- Cache
- Virtual memory
- Secondary storage
- Input and output devices
- Communication hardware
- Computer architectures
- Mobile devices
- Binary and data representation
- Units of measurement
- Cloud computing
You don’t need to memorize every specification of every modern processor.
Instead, make sure you understand what the major components do.
For example, if you are asked why a computer uses RAM, think of RAM as working memory used by the system while programs are running. Storage, such as an SSD or hard drive, is used for longer-term data retention.
Cloud computing is also worth understanding at a basic level. If you want an additional explanation of cloud concepts, see TechDigitalNet’s cloud computing essentials guide.
The official outline specifically includes processing components, primary storage, peripherals, architectures, data representation, and measurement units in this section.
2. Systems Software — 10%
Systems software helps operate and manage the computer itself.
Study concepts such as:
- Operating systems
- Resource allocation
- Job scheduling
- File management
- Virtual computing
- System utilities
- Virus protection
- Backup and recovery
- Disk maintenance
- User interfaces
Know the general purposes of operating systems such as Windows, macOS, Linux, Android, and Unix.
You should also understand the difference between interfaces such as graphical user interfaces, command-line interfaces, menu-driven interfaces, voice interfaces, and touch or gesture-based interfaces.
3. Application Software — 20%
Application software is designed to help users perform specific tasks.
Review:
- Word processing
- Desktop publishing
- Spreadsheets
- Presentations
- Email and communication software
- Multimedia
- Databases
- Graphics
- CAD
- Image processing
- Data mining
- Analytics
- Software licensing
- Software as a service
Database terminology deserves particular attention.
For example, imagine a customer database containing names, phone numbers, addresses, and email addresses.
An individual item such as an email address can be a field, while the collection of information describing one customer can be a record.
You don’t need to become a database administrator. You do need to understand the basic concepts and terminology.
4. Data Communications and Networks — 20%
Networking is another major part of the exam.
Review:
- Internet
- World Wide Web
- Web browsers
- HTML
- Search engines
- Internet service providers
- File transfer
- LAN
- WAN
- Client-server networks
- Peer-to-peer networks
- Network topologies
- Routers
- Switches
- Hubs
- HTTP
- HTTPS
- Firewalls
- Encryption
- Identity and access management
- Wireless networks
Here’s a simple example.
A switch generally connects devices within a local network, while a router connects different networks and directs traffic between them.
You should be able to recognize these distinctions without needing to configure an enterprise network yourself.
Because security is part of the networking material, it can also help to review basic cybersecurity terminology before the exam. TechDigitalNet’s cybersecurity engineer guide provides additional context around cybersecurity concepts and roles.
5. Software Development — 10%
This section covers the fundamentals of creating and maintaining software.
Review:
- Software development life cycle
- Requirements
- Analysis
- Design
- Development
- Debugging
- Testing
- Maintenance
- Procedural programming
- Object-oriented programming
- Compilers
- Interpreters
- Assemblers
- Debuggers
- Profilers
- Editors
A useful way to understand the software development life cycle is to compare it with building a house.
You don’t begin construction before deciding what the building needs to accomplish. You plan and design first, build it, test the result, fix problems, and maintain it afterward.
Software development follows a similar process.
If programming concepts are unfamiliar, you can also review TechDigitalNet’s beginner-friendly guide to learning coding before moving into more advanced software-development terminology.
6. Social Impact and History — 20%
This section is easy to overlook because it isn’t as obviously technical as hardware or networking.
Don’t skip it.
The exam outline includes topics such as:
- Computing history
- Major developments in computing
- Internet history
- User-interface evolution
- Privacy
- Intellectual property
- Telecommunications law
- Accessibility
- Hacking
- Malware
- Identity theft
- Careers in computing
- Social media responsibility
- Artificial intelligence
- Globalization
This section shows that the exam isn’t only about how computers work. It also covers how information technology affects individuals, organizations, and society.
For a broader look at how technology affects business operations and organizational change, you can also read TechDigitalNet’s digital transformation strategy guide.
Computing and Information Technology DSST Exam Blueprint
The official content outline gives the following approximate distribution:
| Content Area | Approximate Weight |
|---|---|
| Computer Organization and Hardware | 20% |
| Systems Software | 10% |
| Application Software | 20% |
| Data Communications and Networks | 20% |
| Software Development | 10% |
| Social Impact and History | 20% |
The percentages are useful when building a study schedule, but don’t interpret them as an exact list of how many questions you will receive from each topic. They are approximate content-area weights from the official outline.
A practical strategy is to spend more review time on the larger sections while still covering the two 10% areas.
What Should You Study First?
Your study order should depend on your existing knowledge.
If you’re new to IT, start with:
- Computer hardware
- Operating systems
- Application software
- Databases and data
- Networking
- Software development
- Privacy, security, history, and technology’s social impact
If you already work in IT, your priorities may be different.
For example, an IT support specialist may already understand operating systems and hardware but need more preparation in software development, intellectual property, or computing history.
Before creating a study schedule, take a diagnostic practice test or quiz.
Your weakest areas should receive the most attention.
15 Computing and IT Concepts Students Commonly Confuse
Similar terms can cause unnecessary mistakes on a multiple-choice exam.
| Concept Pair | Basic Difference |
|---|---|
| RAM vs. Storage | RAM is working memory; storage retains data |
| RAM vs. ROM | RAM is generally writable working memory; ROM is nonvolatile memory |
| Hardware vs. Software | Physical components vs. programs and instructions |
| System Software vs. Application Software | Supports system operation vs. performs user tasks |
| LAN vs. WAN | Local network vs. geographically larger network |
| Internet vs. World Wide Web | Global network infrastructure vs. web-based information/services |
| Router vs. Switch | Connects networks vs. connects devices within a network |
| Authentication vs. Authorization | Verifies identity vs. determines access |
| Compiler vs. Interpreter | Different methods of translating/executing programming code |
| Encryption vs. Hashing | Reversible encryption for confidentiality vs. one-way hashing |
| Client vs. Server | Requests/uses a service vs. provides a service |
| Primary vs. Secondary Storage | Main memory vs. longer-term storage |
| Procedural vs. Object-Oriented Programming | Different approaches to organizing programs |
| Open Source vs. Proprietary Software | Different source-code and licensing models |
| HTTP vs. HTTPS | Standard web protocol vs. HTTP protected with encryption |
Don’t just memorize the table.
Try explaining each difference without looking at your notes. If you can explain the concept in your own words, you’re more likely to recognize it in a question.
How Difficult Is the Computing and Information Technology DSST?
The difficulty depends heavily on your background.
The exam covers several different areas rather than focusing on one narrow IT skill.
A student who has taken introductory computing courses may already recognize many of the terms. Someone with little formal IT education may need more time to learn the vocabulary and relationships between concepts.
The breadth of the exam is important.
You may move from a question about CPU architecture to one about databases, then networking, software development, or privacy.
That’s why broad review is more useful than becoming extremely advanced in one topic.
Computing and Information Technology DSST Readiness Check
Before scheduling the exam, see whether you can answer these questions without looking up the answers:
- What does a CPU do?
- What is the difference between RAM and storage?
- What is the primary purpose of an operating system?
- What is the difference between a LAN and a WAN?
- What does a router do?
- What is a database?
- What is a compiler?
- What are the basic stages of the software development life cycle?
- Why is encryption used?
- What is the difference between authentication and authorization?
- What is intellectual property?
- Why does privacy matter in information technology?
If you struggle with several questions, use those gaps to guide your study.
This isn’t an official DSST scoring system. It’s simply a practical way to identify topics that deserve more review.

During both weeks, use active recall.
Instead of repeatedly reading:
“A router connects different networks.”
Close your notes and ask yourself:
“What does a router do?”
Then explain the answer from memory.
That small change makes study sessions more active and exposes gaps much faster.
What Should You Not Overstudy?
The exam covers software development, networking, security, and other technical subjects, but you don’t need to turn your preparation into professional-level training.
For example, understanding what a compiler does is different from becoming a compiler developer.
Understanding basic network architecture is different from becoming a network administrator.
Understanding database concepts is different from becoming a database administrator.
Your goal is to master the concepts represented in the official exam outline rather than learning every advanced topic connected to computing.
What Score Do You Need to Pass the DSST?
The current ACE National Guide lists 400 as the recommended minimum score for the Computing and Information Technology DSST. ACE also lists a recommendation of 3 semester hours of lower-division baccalaureate credit for candidates meeting that score.
However, don’t interpret 400 as a universal guarantee that your school will award the credit.
Your college or university may have its own requirements for accepting DSST exams.
Before registering, check your school’s policy and confirm:
- Whether it accepts this DSST
- The minimum score it requires
- How many credits it awards
- Which course or requirement the credit satisfies
- Whether the credit counts toward your major or only as an elective
For the current official credit recommendation, check the ACE National Guide before relying on older third-party information.
How Many College Credits Can You Earn?
The current ACE National Guide recommends 3 semester hours for the Computing and Information Technology DSST.
The important question, however, isn’t simply “How many credits?”
It’s:
How will those credits apply to my degree?
For example, a college might apply the exam toward an introductory information technology requirement, while another institution could apply the credit differently.
Check your degree audit or speak with your academic advisor before registering.
Does Every College Accept the Computing and IT DSST?
No. Credit policies vary by institution.
The official DSST guidance provides information for institutions and students and explains that DSST exams are administered through authorized testing arrangements.
Before you register, ask your college:
“Does my school accept the Computing and Information Technology DSST, and if I earn the required score, which requirement will the credit satisfy?”
That question is much more useful than simply asking whether the school “accepts DSST.”
You can also use the official DSST institution information when checking participating or credit-awarding institutions.
How Much Does the Computing and Information Technology DSST Cost?
The current DSST student information lists a $100 test fee per exam, excluding any administrative charges that a testing site may add.
Because testing arrangements and institutional fees can change, confirm the total cost with your selected testing location before scheduling.
How Do You Register for the Computing and Information Technology DSST?
The official DSST process starts with checking your school’s credit policy.
A typical process is:
- Check your college’s DSST policy.
- Confirm that Computing and Information Technology applies to your degree.
- Choose the exam.
- Find an authorized testing location.
- Register for the exam.
- Prepare using the official content outline and practice resources.
DSST information states that exams are administered through authorized testing centers, with testing arrangements depending on the available option and location.
For current testing information, use the official DSST test-center resources.
Best Ways to Prepare for the DSST
Use the Official Content Outline First
The official outline tells you what areas the exam covers and their approximate weights.
Start there instead of building your preparation around random online articles.
The official DSST Computing and Information Technology fact sheet is a useful starting point because it includes the exam information and content outline.
Take a Diagnostic Test
A diagnostic test helps answer a simple question:
What do I actually need to study?
If you already know hardware but consistently miss networking questions, you shouldn’t spend most of your time rereading hardware notes.
Use Active Recall
Close your notes and explain concepts from memory.
For example:
- What is virtual memory?
- What does an operating system manage?
- What does a firewall do?
- What is a database record?
- What is authentication?
Create Comparison Sheets
Make quick-reference tables for easily confused terms.
These are especially useful during the final days before the exam.
Practice Under Time Limits
The exam has 100 questions and a two-hour time limit.
That works out to an average of about 72 seconds per question.
You don’t need to spend exactly 72 seconds on every question, but practicing under time pressure can help you avoid spending too long on one difficult question.
Review Your Mistakes
Don’t only look at your score.
For every missed question, identify the reason.
That turns practice tests into targeted study sessions.
Official DSST Practice Resources
The official DSST website provides preparation resources and practice-exam information. Its practice resources include Computing and Information Technology among the available DSST practice exams.
Before relying heavily on third-party study guides, start with the official materials so your preparation matches the published exam scope.
You can find current practice information through the official DSST practice exam resources.
Third-party resources can still be useful for explanations and additional practice, but the official content outline should remain your reference point for what the exam covers.
Common Computing and Information Technology DSST Mistakes
1. Studying Without the Official Outline
You can spend hours learning interesting IT topics that aren’t central to the exam.
Start with the exam’s actual content areas.
2. Memorizing Definitions Without Understanding Them
Knowing that LAN stands for “Local Area Network” isn’t enough.
You should understand what makes a LAN different from a WAN.
3. Ignoring Networking
Networking represents approximately 20% of the published content outline, so don’t leave it until the last few hours.
4. Ignoring Social Impact and History
This section also represents approximately 20% of the outline.
Privacy, intellectual property, AI, accessibility, history, and technology’s social effects deserve preparation time.
5. Spending Too Much Time on Advanced Programming
The exam includes software development concepts, but your preparation should match the level and scope of the published outline.
6. Taking Practice Tests Without Reviewing Mistakes
A practice score is useful, but the explanations behind your wrong answers are more valuable for planning your next study session.
7. Assuming ACE Credit Automatically Transfers
ACE provides a credit recommendation. Your college determines whether and how the credit is accepted.
Computing and Information Technology DSST vs. a College Course
The two options serve different situations.
| Factor | DSST Exam | Traditional College Course |
|---|---|---|
| Schedule | Exam-based | Semester/course schedule |
| Learning style | Mostly independent preparation | Instructor-guided |
| Assessment | Standardized exam | Coursework and assessments |
| Existing knowledge | Useful for students with prior knowledge | Can provide structured learning |
| College credit | Depends on institutional policy | Usually part of normal course enrollment |
| Preparation | Focused exam preparation | Broader course experience |
If you’ve already learned much of the material through work, previous study, or independent learning, a DSST may be worth investigating.
If you need structured instruction, assignments, and ongoing feedback, a traditional course provides a different learning experience.
The key is to compare the option with your degree requirements, schedule, budget, and current knowledge.
