(^54) PC Hardware: A Beginner’s Guide
Sockets and Slots
Microprocessors are attached to the motherboard of the computer (see Chapter 4). There
are two general types of mountings used to connect the processor onto the motherboard:
sockets and slots. Some processors are available in only one mounting type; others, such
as the Intel Celerons, are available with both types of mountings. Which type is used is
largely a matter of preference on the part of the processor manufacturer. The two types
look very different, but functionally their differences are small.Socket Types
Here are ten of the most commonly used socket types: Socket 0 A 168-pin inline-layout processor connector for 5V 486DX
processors.
Socket 1 A 169-pin inline-layout processor connector for 5V 486DX and
486SX processors.
Socket 2 A 238-pin inline-layout processor connector for 5V 486DX, 486SX,
and 486DX2 processors.
Socket 3 A 237-pin inline-layout processor connector supporting 3 and 5V
486DX, 486SX, 486DX2, and 486DX4 processors.Figure 3-8. A microprocessor heat sink
