The PGA socket has pins on the bottom of the package aligned in uniform rows.
The SPGA socket has pins on the bottom of the package that are staggered to squeeze more pins into a small space.

Earlier Pentiums used a pin grid array ( PGA ) socket, with pins aligned in uniform rows around the socket. Later sockets use a staggered pin grid array ( SPGA ), with pins staggered over the socket to squeeze more pins into a small space.
PGA (Pin Grid Array) sockets feature pins arranged in a grid pattern on the underside of a chip, which insert directly into corresponding holes in the socket. In contrast, SPGA (Staggered Pin Grid Array) sockets have pins that are staggered, allowing for a more compact design and better signal integrity, as well as improved thermal performance. This staggered arrangement can accommodate higher pin counts while reducing the overall footprint of the socket. Additionally, SPGA sockets are often used in applications requiring higher performance and density compared to standard PGA sockets.
Because the pins on the bottom of the processor can be easily bent (assuming that this is a processor for a PGA (Pin Grid Array) or SPGA (Staggerd PGA) socket. It is worth noting though that a processor for a LGA (Land Grid Array) socket is not as susceptible to this as the there are lands or pads on the bottom of the processor instead of pins; the pins are in the socket. The book that asks this question assumes PGA. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Very true BUT you can bend the lands in an LGA socket, rendering the socket hence the motherboard useless!
LGA : Land Grid Array <== pins are in the socket, no pins are attached on the CPU, only pads. PGA: Pin Grid Array <== pins are attached on to the socket, the socket has some sort of "holes" that hold the processor
The CPU is the identifying factor of a pga socket
It is a type of array to fit into an intel Socket 370 or Socket 478 CPU socket.
