D794: Computer Architecture and Systems

A guide to WGU's D794, the graduate course on computer system design across hardware and software, multiple platforms and device integration.

Updated October 2026 · 5 min read

D794 is a graduate course in WGU's Master of Science, Computer Science programs.

According to WGU's description it examines how computer systems are designed and developed, including how architecture has evolved, the different hardware and software layouts used, and how to plan computing solutions that work across platforms and devices.

The challenge is breadth with a design emphasis. Instead of memorizing components, you decide which architecture suits a use case and explain how devices will work together. The guide lists three competency units and the course appears in the AI and Machine Learning and Human-Computer Interaction plans.

What D794 Covers

Recommend multi-platform solutionsPlan compatibility, communication and consistent behavior

Key Concepts Explained

Architecture Trade-Offs

Architecture choices trade performance, power, cost and flexibility. Parallel cores, caches, memory hierarchies and specialized accelerators each solve a bottleneck at a price. A recommendation should name the bottleneck first.

Example: A battery-powered sensor that sends small readings needs low power more than speed, so a simple low-power processor suits it. A video analysis server needs throughput, so many cores or a graphics accelerator makes sense.

The Hardware and Software Stack

Applications sit on operating systems, which manage hardware through drivers and firmware. Portability depends on interfaces: standard protocols and abstraction layers let the same software run on different devices.

Example: A smart home product runs on a phone, a hub and several sensors. Choosing a common messaging protocol and a standard data format lets each device communicate without custom code for every pair.

Integration and Communication

Devices communicate over wired and wireless links with different range, speed and power needs. Design must also cover synchronisation, failure handling and security of those links.

Typical Assignments and How to Approach Them

Task elementWhat it testsHow to approach it
Historical analysisGrasp of change over timeTrace one driver, such as the shift to multi-core, and its effect on software
System designJoining hardware to softwareList components, their roles and the reason for each choice
Platform recommendationMulti-device fitCompare platforms on resources and update paths
Device planHow devices talkState protocols, data formats and failure behavior

A Worked Platform Comparison

A compact comparison table shows that you reasoned about platforms instead of listing them. Use the constraints from your own scenario.

Finish with a recommendation that assigns each task to the platform best placed to do it, such as local alerts on the hub and long-term analysis in the cloud.

Readiness Checklist Before You Submit

Check the answer against the three competencies.

CheckWhat to confirm
Evolution analyzedYou link a historical change to a present design choice
Components justifiedEach hardware and software choice has a reason
Platforms comparedAt least two platforms are compared on your constraints
Integration explainedProtocols, data formats and failure behavior are stated
Risks notedCompatibility and security concerns are acknowledged

Splitting Your Study Time

The course is mostly design reasoning, so time spent sketching and comparing pays off more than memorizing components. Start from a scenario you can picture, such as a connected home or a hospital ward.

How We Help with D794

Send the task, rubric and any draft. A writer with a systems or embedded background can prepare a worked model design for study, explain architecture trade-offs, or review your design for missing integration reasoning. Our master's assignment help guide explains the process.

GradeEssays is independent of Western Governors University. Model work is for study and reference; your submission must be your own under WGU's academic integrity policy, and no result is promised. Orders are written from scratch with free revisions within the scope of your original request, and a full refund if late.

Frequently Asked Questions

Which programs include D794?

WGU's guides list it in the M.S. Computer Science plans for AI and Machine Learning, and Human-Computer Interaction.

How many competency units is D794?

Three, according to the guides.

Is this the same as the undergraduate architecture course?

No. C952 is the undergraduate course; D794 is a graduate course with a design and integration focus.

Do I need electronics knowledge?

Basic familiarity with processors, memory and communication helps, but the emphasis is architectural reasoning.

How do I show cross-platform thinking?

Compare platforms against your constraints and say how one design adapts to each.

What counts as integration?

How devices communicate, share data, stay synchronised and recover from failure.
