CPU Sockets:
What kind of CPU socket is commonly paired with a Pin Grid Array (PGA) processor package? ----
--- ✔ CORRECT ANSWER ✓✓Answer: Zero Insertion Force (ZIF)
Explanation: The Zero Insertion Force socket is commonly paired with a processor that uses the
PGA package. The PGA processor has pins that a gently placed on a ZIF (the zero insertion
force). A bar is used to lock the processor in place without using any undue pressure on the
motherboard.
CPU Sockets:
DIP ------- ✔ CORRECT ANSWER ✓✓That stands for Dual Inline Package
That's because on these older types of CPUs, you had these two sets of pins at the bottom that
had to be very carefully pushed into the motherboard.
CPU Sockets:
SECC ------- ✔ CORRECT ANSWER ✓✓That stands for Single Edge Contact Cartridge
We started seeing this with the Intel Pentium II. It's a big plastic connection that had this slot
right at the bottom that you would use to plug into the motherboard.
, CPU Sockets:
PGA ------- ✔ CORRECT ANSWER ✓✓That stands for Pin Grid Array
And if you look at the bottom of the CPU, there are all these tiny pins at the bottom. That is the
array of the pins that are arranged in that grid. So that's our pin grid array.
CPU Sockets:
ZIF ------- ✔ CORRECT ANSWER ✓✓That stands for Zero Insertion Force
This is called a ZIF socket. And it had this bar- this arm- on the side of it. We would simply, lightly
place the CPU onto the exact pins associated with the socket on the motherboard. And we
would simply close that arm to lock it in place.
CPU Sockets:
LGA ------- ✔ CORRECT ANSWER ✓✓That stands for Land Grid Array
It's the same idea that we had with the PGAs, but instead of the pins being on the CPU, we now
have the pins on the motherboard. The CPU itself has no pins associated with it, which makes it
a lot easier for the manufacturer to create the CPUs. If you have an i3, an i5, an i7 processor, it's
probably going to have an LGA type connection on the back of it.
CPU Sockets:
What is a common characteristic of an Land Grid Array (LGA) socket? ------- ✔ CORRECT ANSWER
✓✓Answer: The pins are on the motherboard
