A CPU socket or CPU slot is a connector on a computer's motherboard that accepts a CPU and forms an electrical interface with it. Socket 370 (also known as the PGA370 socket) is a common format of CPU socket first used by Intel for Pentium III and Celeron ZIF is an acronym for zero insertion force, a concept used in the design of IC sockets invented to avoid problems caused by applying force upon insertion and A pin grid array, often abbreviated PGA, refers to the arrangement of pins on the integrated circuit packaging Socket A (also known as Socket 462) is the CPU socket used for AMD processors ranging from the Athlon Thunderbird to the Socket A (also known as Socket 462) is the CPU socket used for AMD processors ranging from the Athlon Thunderbird to the A motherboard is the central or primary Printed circuit board (PCB making up a complex electronic system such as a modern Computer or Laptop As of 2007, most desktop and server computers, particularly those based on the Intel x86 architecture, include socketed processors. Year 2007 ( MMVII) was a Common year starting on Monday of the Gregorian calendar in the 21st century. A desktop computer is a Personal computer (PC in a form intended for regular use at a single location as opposed to a mobile Laptop or portable computer A server is a Computer dedicated to providing one or more services over a computer network typically through a request-response routine See also X86 assembly language The generic term x86 refers to the most commercially successful Instruction set architecture in the history of Personal

Most CPU-sockets interfaces are based on the pin grid array (PGA) architecture, in which short, stiff pins on the underside of the processor package mate with holes in the socket. A pin grid array, often abbreviated PGA, refers to the arrangement of pins on the integrated circuit packaging Microchipsjpg|right|thumb|200px|Microchips ( EPROM memory with a transparent window showing the integrated circuit inside To minimize the risk of bent pins, zero insertion force (ZIF) sockets allow the processor to be inserted without any resistance, then grip the pins firmly to ensure a reliable contact after a lever is flipped. ZIF is an acronym for zero insertion force, a concept used in the design of IC sockets invented to avoid problems caused by applying force upon insertion and

As of 2007, several current and upcoming socket designs use land grid array (LGA) technology instead. Year 2007 ( MMVII) was a Common year starting on Monday of the Gregorian calendar in the 21st century. The land grid array ( LGA) is a type of Surface-mount packaging used for Integrated circuits It can be electrically connected In this design, it is the socket which contains pins. The pins contact pads or lands on the bottom of the processor package.

In the late 1990s, many x86 processors fit into slots, rather than sockets. CPU slots are single-edged connectors similar to expansion slots, into which a PCB holding a processor is inserted. An expansion card (also expansion board, adapter card or accessory card) in Computing is a Printed circuit board that can be inserted A printed circuit board, or PCB, is used to mechanically support and electrically connect Electronic components using conductive pathways or traces Slotted CPU packages offered two advantages: L2 cache memory could be upgraded by installing an additional chip onto the processor PCB, and processor insertion and removal was often easier.

In Electronics, a signal trace on a Printed circuit board (PCB is the equivalent of a Wire for conducting signals Each trace consists A chipset is a group of Integrated circuits or chips that are designed to work together and are usually marketed as a single product The hertz (symbol Hz) is a measure of Frequency, informally defined as the number of events occurring per Second. Slots were abandoned with the introduction of AMD's Socket A and Intel's Socket 370. Socket A (also known as Socket 462) is the CPU socket used for AMD processors ranging from the Athlon Thunderbird to the Socket 370 (also known as the PGA370 socket) is a common format of CPU socket first used by Intel for Pentium III and Celeron

  3. ^ a b c d These sockets are for CPUs with integrated memory controllers. The 754 pin models have a single memory channel routed through the CPU pins. The 939 pin models have two memory channels, hence the higher pin count. The 940 pin CPUs also have two memory channels but they require registered memory, and most have support for SMP. In Computing, symmetric multiprocessing or SMP involves a Multiprocessor computer-architecture where two or more identical processors can connect to a single Sockets F and AM2 are redesigned to support DDR2. The Socket F contains 1207 pins (Added pins speculated to be for more scalability and better power distribution). Socket AM2 has 940 pin-holes but does not support current AMD Opteron processors.
  4. ^ a b c The 478 pin socket was introduced because it uses a micro-PGA layout which is physically smaller than the socket 423. Socket 775 was introduced with support for PCI express, DDR2 memory and Intel 64 (Intel's implementation of x86-64), but also moved to the new Land Grid Array physical layout, where the pins are in the socket rather than on the CPU package, for better electrical performance.
