Instruction Set Architectures
Instruction Set Architectures (ISAs) like x86-64 are what determine the actual byte sequences a compiler outputs for the specified ISA.
Those byte sequences then map literally to instructions on the CPU.
source code -> compiler targeting an ISA -> machine-code bytes -> CPU decodes bytes and executes instructions
They are like they key that defines the values a compiler can output to map to instructions for a CPU.
Git tree objects are snapshots
A Git tree records a directory's entries at one point in history. A commit points to a tree, which is why comparing commits can identify which files changed.
