Questions & Answers about הנציג במוקד אמר שיש תקלה במחשב.
Here מוקד most naturally means call center, service center, or hotline desk, not literally just focus or center.
So הנציג במוקד means the representative at the call center / hotline.
This is a very common modern use of מוקד in customer-service contexts.
In unpointed Hebrew, both are written the same way: במוקד.
- be-moked = in/at a center
- ba-moked = in/at the center
The same thing happens with במחשב:
- be-machshev = in a computer
- ba-machshev = in the computer
Hebrew usually leaves out vowel marks, so you decide from context. In this sentence, a native speaker will usually understand במוקד as at the call center and במחשב as in the computer.
אמר is the past tense, third person masculine singular form of to say.
