Ever stared at a diagram in a textbook or a certification exam and thought, "Okay, but which of these flow chart concepts is actually being shown here?" You're not alone. Half the battle with flow charts isn't drawing them — it's reading them, and knowing what the little shapes are trying to tell you.
The phrase "which of the following flow chart concepts is depicted below" shows up all over the place. And it's a fair question. Practice tests, job training, even those annoying onboarding slides. Because a flow chart is just a bunch of boxes and arrows until you know the visual language behind it.
So let's talk about that language. On the flip side, not the boring standards-doc version. The real, practical stuff you need when you're squinting at a shape and trying to name it.
What Is A Flow Chart Concept
A flow chart concept is just a named idea that explains what a part of a diagram means. Think of it like grammar for pictures. Practically speaking, a rectangle isn't just a rectangle — it's probably a process. A diamond isn't decoration — it's a decision Easy to understand, harder to ignore..
When someone asks which of the following flow chart concepts is depicted below, they're pointing at one shape or one connection and asking you to label the idea behind it. The concepts are the vocabulary: process, decision, terminator, input/output, connector, loop, merge, and so on Easy to understand, harder to ignore..
The Core Shapes You'll Actually See
Most real-world charts lean on a small set of shapes. Here's the short version:
- Terminator — rounded ends, usually "Start" or "End"
- Process — rectangle, a step or action
- Decision — diamond, a yes/no fork
- Input/Output — parallelogram, data in or out
- Connector — small circle, jumps across the page
If you know those five, you can decode maybe 90% of what gets thrown at you in a "which of the following" question Small thing, real impact..
Why The Concept Matters More Than The Drawing
Look, anyone can draw a box. But the concept tells you why it's there. A diamond means the path splits. A parallelogram means the system talks to the outside world. That's the difference between reading a chart and just looking at one Not complicated — just consistent..
Why It Matters / Why People Care
Why does this matter? Because most people skip it. They memorize "diamond = decision" for the test and forget it by Friday. Then they're in a meeting, someone puts a flow chart on the screen, and nobody can tell if the circle is a connector or just a typo.
In practice, misreading a flow chart concept causes real messes. Plus, a developer thinks a parallelogram is a process and builds the wrong API call. A analyst sees a connector and assumes the flow ended. A student picks "loop" on a quiz when the picture is clearly a "decision" — and loses the point.
Turns out, knowing which concept is depicted below is a low-key superpower. It makes documentation readable. Consider this: it makes onboarding faster. And it makes you the person who can say, "Actually, that's a merge, not a decision" without sounding like a jerk.
Here's what most people miss: the concepts aren't arbitrary. They come from standards like ANSI and ISO, but more importantly, they come from decades of people trying to make logic visible. When you learn the concept, you're joining that conversation Small thing, real impact..
How It Works (or How to Do It)
So how do you actually figure out which of the following flow chart concepts is depicted below? You don't guess. You run a small mental checklist.
Step 1: Look At The Shape, Not The Words
The text inside a box is a hint, but the shape is the rule. A diamond with the word "Send Email" is still a decision shape — even if the label is sloppy. So exams love this trick. They put a process-looking label in a decision shape and watch you fail Less friction, more output..
Train your eye to see geometry first. Rectangle = do something. Rounded = start/stop. Diamond = choose. Parallelogram = data. Circle = hop.
Step 2: Follow The Arrows
Arrows tell you flow. One arrow in, one out? That said, probably a process. One in, two out? So naturally, that's a decision or a fork. Two in, one out? Worth adding: that's a merge. No arrows? Could be a terminator or a disconnected mistake.
In practice, I trace the arrows with my finger (yes, on screen, like a caveman). It sounds dumb. It works Easy to understand, harder to ignore..
Step 3: Count The Entry And Exit Points
This is the part most guides get wrong. They say "decision has two arrows.But the concept is still decision. " Not always. Even so, a decision can have three if there's an error path. What you're really counting is whether the logic branches (splits) or combines (joins).
- Splits = decision, fork, or broadcast
- Combines = merge or join
- Straight through = process or terminator
Step 4: Check For Loops And Cycles
A loop happens when an arrow points backward. On the flip side, the concept depicted might be "iteration" or "repeat. So if the question shows a box with an arrow curving back to an earlier diamond, the answer isn't "rectangle." But here's the thing — the loop itself isn't a shape. It's a pattern of arrows. " It's "loop" or "cycle.
Step 5: Match To The Answer List
When the prompt says "which of the following flow chart concepts is depicted below," the options are your cage. You're not naming anything — you're picking from their list. So map what you see to their words. Because of that, if they say "connector" and you see a small circle with an arrow jumping over a gap, that's it. Don't overthink.
Not obvious, but once you see it — you'll see it everywhere The details matter here..
A Quick Example
Picture this: a rounded rectangle says "Start." Arrow to a rectangle "Boil water.And " Arrow to a diamond "Tea ready? In real terms, other arrow goes to a parallelogram "Pour cup. That said, " One arrow from diamond goes back to the rectangle. " Then to rounded "End It's one of those things that adds up. Still holds up..
Question: which concept is depicted by the diamond with the arrow going back? Answer: decision (with a loop implied). On the flip side, not process. Not terminator.
Common Mistakes / What Most People Get Wrong
Honestly, this is the part most guides get wrong. They list shapes and call it a day. But the mistakes people make are more interesting.
Mistake 1: Trusting the label over the shape. If the shape says one thing and the geometry says another, the shape wins in any serious context. Exams know this. Real systems sometimes don't — and that's how bugs happen.
Mistake 2: Calling every circle a connector. A small circle is a connector. A big circle might be a delay in some engineering charts, or just a weird process. Context matters.
Mistake 3: Missing the merge. Two arrows into one box? People see a process and ignore the fact that paths combined. The concept is merge. That changes how you understand the system — two paths means two possible histories.
Mistake 4: Confusing a fork with a decision. A fork splits flow without a condition (think: send to two systems at once). A decision splits on a condition. Both have two outs. Different concepts That alone is useful..
Mistake 5: Thinking "below" means the whole chart. In "which of the following flow chart concepts is depicted below," the depicted thing is usually one element. Don't describe the entire diagram. Zoom in.
Practical Tips / What Actually Works
Real talk — if you want to get good at this, don't just read about it. Do a few reps.
- Print a cheat sheet of shapes. Stick it by your monitor. After a week you won't need it.
- Take 3 practice questions a day. Search "which of the following flow chart concepts is depicted below" and do the images. It's a muscle.
- Draw your own messy chart. Then label every shape with its concept. You'll catch your own confusion fast.
- When in doubt, ask: does the path split, join, or continue? That question alone solves most "which concept" puzzles.
- Learn the ugly cousins. Swimlane charts, data flow diagrams — they borrow the concepts but change the rules. Know the base before the variant.
I know it sounds simple
, but that simplicity is exactly why people trip over it. Here's the thing — the moment you stop treating flowcharts like mysterious diagrams and start seeing them as a tiny vocabulary of shapes and arrows, the whole thing clicks. You stop guessing and start reading.
The truth is, most "which concept is depicted" questions aren't testing your intelligence—they're testing whether you noticed the shape, the direction, and the rule behind it. A diamond is a decision. A circle with an arrow is a connector. Which means a box that two arrows hit is a merge. That's the entire game Simple, but easy to overlook..
So next time you see one of those questions, don't panic and don't overanalyze the wording. Look at the geometry, trust the shape, and answer the one question that matters: what is this element doing to the flow?
Conclusion: Flowchart literacy isn't about memorizing dozens of rules—it's about recognizing a handful of basic concepts and applying them without hesitation. Master the shapes, respect the arrows, and you'll never again freeze on a "which of the following flow chart concepts is depicted below" question. The diagram already told you the answer. You just have to see it.
