boot block
<operating system> A program at some fixed location on a {hard
disk}, floppy disk or other media, which is loaded when the
computer is turned on or rebooted and which controls the next
phase of loading the actual operating system. The loading
and execution of the boot block is usually controlled by
firmware in ROM or PROM.

Boot sector
A boot sector is the sector of a persistent data storage device (e.g., hard disk, floppy disk, optical disc, etc.) which contains machine code to be loaded into random-access memory (RAM) and then executed by a computer system's built-in firmware (e.g., the BIOS).
Usually, the very first sector of the hard disk is the boot sector, regardless of sector size (512 or 4096 bytes) and partitioning flavor (MBR or GPT).
The purpose of defining one particular sector as the boot sector is inter-operability between firmware and various operating systems.
The purpose of chainloading first a firmware (e.g., the BIOS), then some code contained in the boot sector, and then, for example, an operating system, is maximal flexibility.
