noun
Computing term for a jump or transfer instruction in programming, such as a branch or goto.

ジャンプ is a general loanword for 'jump', while 飛び越し is a technical computing term for a program jump or transfer.
Compound of 飛び (tobi, 'jumping', continuative form of 飛ぶ) + 越し (koshi, 'crossing over', continuative form of 越す). The computing sense is a semantic extension of the literal meaning.
