Don't say this
Queue as a data structure is not used for physical lines of people in tech contexts. Use it for data or tasks only.

More about queue
Real examples(4)
- in an incident call
"The queue depth is climbing, so the workers can't keep up with incoming orders."
- in a design review
"We will put the email job on a queue so the API can respond immediately."
- in a standup
"My build has been in the queue for twenty minutes."
- in a support meeting
"Can we look at the oldest tickets in the support queue first?"
More mistakes(2)
Handle with care. Non-native speakers sometimes confuse queue (data structure) with queue (waiting line). In tech, it almost always means the data structure unless discussing customer support or ticketing systems.
- ✕The queue will process items randomly.✓The queue will process items in FIFO order.
A queue by definition processes items in the order they were added, not randomly. If you need random access, use a different data structure.
- ✕I queued the message but it processed immediately.✓I added the message to the queue, but it processed immediately because the queue was empty.
Queuing does not guarantee a delay; if the queue is empty, processing may happen right away.

- queue verb

Questions(7)
- What is a queue in programming?
- A data structure where you add items at the back and remove them from the front, like people waiting in line. The first item in is the first item out.
- What are message queue technologies?
- Tools that pass messages between services so they do not have to wait for each other. Common examples are RabbitMQ, Amazon SQS, Apache Kafka and Google Pub/Sub.
- What does FIFO mean?
- FIFO means first in, first out. The first item that enters the queue is the first item that leaves it.
- What is the difference between a queue and a stack?
- A queue is first in, first out, like a line of people. A stack is last in, first out, like a pile of plates, where you take the top one first.
- What is a message queue used for?
- It holds messages between parts of a system so they do not have to work at the same speed. One part adds work, another processes it later, which smooths traffic spikes and makes systems more reliable.
- What does queue depth mean?
- Queue depth is the number of items waiting. If it keeps growing, work is arriving faster than it is processed, and you may need more workers.
- How do you pronounce queue, and is it line in American English?
- Queue sounds like the letter Q. British English also uses queue for a line of people, while American English usually says line. In software, both use queue.
