Which socket types are used with Pentium 4 processors?

  1. 423 or 478

  2. 1150 or 1155

  3. 1366 or 1156

  4. 1155 or 1156

The correct answer is: 423 or 478

Firstly, it is important to note that Pentium 4 processors are older models, so the socket types used with them may differ from more recent processors. Option A, 423 and 478, are the two socket types that were specifically designed for use with Pentium 4 processors. Option B and C, 1150 and 1366 respectively, were not designed for Pentium 4 processors as they came out later and were intended for newer processor models. Option D, 1155 and 1156, were also designed for newer processors and are not compatible with Pentium 4 processors. Therefore, Option A is the correct answer.
