FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -In a PGA architecture, pins on the underside of the processor are inserted into the socket, usually with zero insertion force (ZIF). ZIF refers to the amount of force needed to install a CPU into the motherboard socket or slot. In an LGA architecture, the pins are in the socket instead of on the processor.

Detailed explanation-2: -LGA – Land Grid Array LGA is the surface mounting packaging for ICs (Integrated Circuits). It has contact pins on the motherboard socket and not on the chip which sets it apart from PGA.

Detailed explanation-3: -Common types of CPU sockets include the Pin Grid Array (PGA) and the Land Grid Array (LGA). The difference between the two is that PGA places the pins on the processor and the holes in the socket, whereas LGA has a socket with pins that you place the processor on.

Detailed explanation-4: -A land grid array (LGA) socket can provide compressive electrical interconnect between the printed circuit boards (PCB) and the processor. LGA sockets are one of the latest socket technologies for x86 LGA microprocessor packages that range in size up to 4200 pins.

Detailed explanation-5: -Sure, the technical specifications of the sockets are iterated upon, but the type of socket technology used in the lineup of a particular company remains more or less the same. Intel uses LGA, AMD prefers PGA, and mobile processors are almost always BGA.
