A.
Socket 423

B.
Socket 462

C.
Socket 478

D.
Socket 754

E.
Socket A

Explanation:
Socket 478 is a type of CPU socket used for Intel’s Pentium 4 and Celeron series CPUs.
Incorrect Answers:
A: Socket 423 is a CPU socket that was used for the first Pentium 4 processors based on
theWillamette core. However, it was short-lived as it quickly became apparent that it had
inadequate electrical design, which would have not allowed many clock-speed rises above 2.0
GHz. It was replaced by Socket 478.
B: Socket A (also known as Socket 462) is the CPU socket used for AMD processors ranging from
the Athlon K7 to the Athlon XP 3200+, and AMD budget processors including the Duron and
Sempron.
D: Socket 754 is a CPU socket originally developed by AMD to succeed its powerful Athlon XP
platform (Socket 462, also referred to as Socket A).
E: Socket A (also known as Socket 462) is the CPU socket used for AMD processors ranging from
the Athlon K7 to the Athlon XP 3200+, and AMD budget processors including the Duron and
Sempron.
