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.
A PGA socket has pins aligned in uniform rows around the socket. Where an SPGA socket has pins staggered over the socket to squeeze more pins into a small space.
PGA Pins are aligned in uniform rows around the socket.
SPGA pins are staggered over the socket to squeeze more pins into a small space.

1) SGA is SYSTEM GLOBAL AREA, where is PGA PROGRAM GLOBAL AREA.
2) SGA invloves shared_pool, dictionary cache, log buffer, large_pool area where PGA contains the user session info.
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.
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
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!
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.

2005 is better
PGA socket - Pin grid array
Socket 478
Am3 pga
PGA Pin Grid Array is the socket that holds the CPU, there is also the LGA/ land grid array
