Which of these is not a type of socket? AGA (alternating grid array) PGA (pin grid array) SPGA (staggered pin grid array) LGA (land grid array)
The Correct Answer and Explanation is:
The correct answer is AGA (alternating grid array).
Explanation:
In the world of computer hardware, particularly processors, a socket is a physical interface used to connect the CPU to the motherboard. These sockets have different configurations for pin or contact arrangements, which help ensure proper connectivity between the CPU and the motherboard’s circuit board. Let’s go over the types listed:
- PGA (Pin Grid Array): This type of socket has numerous pins arranged in a grid on the bottom of the CPU. The pins are inserted into corresponding holes on the motherboard socket, allowing for an electrical connection. PGA is commonly used in older processors and some modern ones as well.
- SPGA (Staggered Pin Grid Array): This is a variation of the PGA socket. In this type, the pins are arranged in a staggered fashion, which helps improve the density of the pins and may reduce the risk of damage during installation. The staggered arrangement allows for a more efficient design while maintaining proper contact.
- LGA (Land Grid Array): In contrast to the PGA, LGA uses a different design. The CPU itself has small contact pads (lands), and the motherboard has corresponding pins. When the CPU is placed into the socket, the pads make contact with the pins, ensuring a proper connection. LGA is widely used in modern processors, especially in Intel chips.
- AGA (Alternating Grid Array): This is not a recognized type of socket. The term “Alternating Grid Array” doesn’t exist in standard CPU socket terminology. It seems to be a mix-up or mislabeling of the other socket types.
Thus, AGA is not a type of socket, while PGA, SPGA, and LGA are all valid and commonly used socket types.
