Socket 1
Encyclopedia
Socket 1 was the second of a series of standard CPU socket
s created by Intel into which various x86 microprocessor
s were inserted. It was an upgrade to Intel's first standard pin grid array
(PGA) socket and the first with an official designation. Socket 1 was intended as a 486 upgrade socket, and added one extra pin to prevent upgrade chips from being inserted into the older socket.
Socket 1 was a 169-pin low insertion force
(LIF) 17×17 pin grid array
(PGA) socket suitable for the 5-volt
, 16 to 33 MHz 486 SX, 486 DX, 486 DX2 and 486 OverDrive processors.
CPU socket
A CPU socket or CPU slot is a mechanical component that provides mechanical and electrical connections between a microprocessor and a printed circuit board . This allows the CPU to be replaced without soldering....

Microprocessor
A microprocessor incorporates the functions of a computer's central processing unit on a single integrated circuit, or at most a few integrated circuits. It is a multipurpose, programmable device that accepts digital data as input, processes it according to instructions stored in its memory, and...

Pin grid array
A pin grid array, often abbreviated PGA, is a type of integrated circuit packaging. In a PGA, the package is square or roughly square, and the pins are arranged in a regular array on the underside of the package...

Volt
The volt is the SI derived unit for electric potential, electric potential difference, and electromotive force. The volt is named in honor of the Italian physicist Alessandro Volta , who invented the voltaic pile, possibly the first chemical battery.- Definition :A single volt is defined as the...
