What is the difference between a PGA scoket and an SPGA socket?

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.

What is the difference between a SPGA socket and an PGA socket?
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.

Has a 39 x 39 SPGA grid?
Socket 423

staggered pin grid array (SPGA)
What does SPGA stand for in CPU packages?
SPGA stands for Staggered Pin Grid Array. For more information, read the article here: http://en.wikipedia.org/wiki/Staggered_Pin_Grid_Array
Why is it important to insert a processor straight down into a socket rather than sliding the processor in from the side or allowing it to tilt into the socket?
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!
What has a lever that is used to lift the processor up and out of the socket?
zero insertion force sockets (see page 178 in A+ Guide to Managing and Maintaining Your PC) "PGA, SPGA, and LGA sockets are all square or nearly square. So that even force is applied when inserting the processor in the socket, all current processor sockets have a lever on the side of the socket. These sockets are called zero insertion force (ZIF) sockets, and this lever is used to lift the processor up and out of the socket. Push the lever down and the processor moves into its pin or land connectors with equal force over the entire housing."
