Morphology

central + processing + unit

Each constituent directly contributes to the overall meaning: 'central' = main, 'processing' = performing operations/handling data, and 'unit' = a component, so a learner can infer it is the main component that performs processing. This compositional structure is regular and mirrored in many languages (e.g. Spanish 'unidad central de procesamiento'), making the term broadly predictable for a B1 learner who knows the words.

Etymology

Central processing unit is a name that gives a clear picture: central means 'main', processing means 'working on data', and unit means 'one device'. Think of it as the computer's 'brain' in the middle that does most of the thinking and tells the other parts what to do, so today the term means the main part that controls and processes data.
