Morphology
The technical sense in computing is a metaphorical extension of the physical gesture 'shake hands' (an act of greeting or agreement), so a learner who knows 'shake' and 'hand' can probably infer a general meaning of 'establishing a connection or agreement'. However, the specific notion of exchanging protocol messages or negotiating session parameters is technical and not directly predictable from the constituents, so full comprehension requires domain knowledge.
Etymology
Shake hands in technology uses the picture of two people touching hands to agree: devices send short messages back and forth like a handshake to show they both accept the same rules. So when computers 'shake hands' they are agreeing on how to talk before they start to send data.
