CompTIA A+ 220-801 Processors And Socket Types

PGA stands for Pin Grid Array. It is a type of integrated circuit packaging that uses an array of pins to connect the chip to the circuit board. The pins are arranged in a grid pattern, hence the name "Pin Grid Array". This packaging technology is commonly used in CPUs, memory modules, and other high-performance electronic components. The pins provide a secure and reliable connection between the chip and the circuit board, ensuring efficient data transfer and electrical conductivity.

LGA stands for Land Grid Array, which refers to a type of packaging technology used for integrated circuits. It involves an array of pins or pads on the surface of a microprocessor, which are used for connecting it to a printed circuit board (PCB). LGA provides a more reliable and efficient way of connecting the microprocessor to the PCB, compared to other packaging technologies. It is commonly used in computer processors and other high-performance electronic devices.

LGA 775 is a correct answer because it is an Intel socket. LGA stands for Land Grid Array, which is a type of CPU socket used by Intel processors. The number 775 refers to the number of pins on the socket. This socket was commonly used for Intel processors in the mid-2000s, such as the Core 2 Duo and Core 2 Quad series. AMD2 and AMD2+ are incorrect answers because they are sockets used by AMD processors, not Intel. FMI is not a recognized socket for either Intel or AMD processors.

The statement "Xeon is an Intel chip" is true. Xeon is a brand of x86 microprocessors designed and manufactured by Intel. These chips are specifically designed for servers, workstations, and high-end computing devices. Xeon processors are known for their high performance, advanced features, and reliability, making them popular in data centers and enterprise-level applications.

The FM1 socket would not fit a Celeron processor because it is designed for AMD processors, not Intel processors like the Celeron. The other three sockets, LGA 775, LGA 1155, and LGA 1366, are all Intel sockets that are compatible with Celeron processors.

Socket 940 is a type of CPU socket that was used by AMD processors. It supports dual-channel memory, which means that it can access two memory modules simultaneously, increasing the overall memory bandwidth. This allows for faster data transfer and improved system performance. Therefore, the statement that Socket 940 supports DDR dual channel memory is true.

The Core 2 Duo chip fits into the LGA 775 socket.

The Intel socket type LG1366 supports DDR3 triple channel memory. This socket type was introduced with the Intel Core i7 processors and is designed to support three DDR3 memory modules, allowing for increased memory bandwidth and improved performance. LG775, LG155, and LG1156 are not compatible with DDR3 triple channel memory.

The Itanium chip is the correct answer because it is specifically designed to run only in 64-bit mode. It is a high-performance microprocessor developed by Intel and is optimized for large-scale enterprise applications. Itanium processors have a unique architecture that allows them to efficiently process large amounts of data in a 64-bit environment, making them ideal for demanding computational tasks.

The Intel Core i7 chip fits into the LGA 1155, LGA 1156, and LGA 1366 sockets. These sockets are specifically designed to be compatible with Intel Core i7 processors.

The correct answer is AMD 940 and AMD2. Both of these AMD sockets have 940 pins.

AM3 has 941 pins.

The correct answer is LGA 1155 and LGA 1156. The Core i3 chip is designed to fit into these specific sockets, which are commonly used for Intel processors. LGA 1155 and LGA 1156 sockets are compatible with different generations of Core i3 chips, allowing for easy upgrades or replacements.

Socket F is a Land Grid Array (LGA) socket. This type of socket uses an array of pins on the motherboard, rather than on the CPU, to make contact with the CPU. Socket F is specifically designed for AMD processors and is commonly used in server and workstation systems.

The correct answer is AMD 940, AM2, AM2+. All three of these options have 940 pins.

The FM1 socket is the correct answer because it is specifically designed to support only DDR3 dual channel memory. AMD, AM3+, and Socket F are not limited to DDR3 dual channel memory and can support other types of memory configurations as well.

The Xeon and Celeron processors fit into all four of the common Intel chip sockets LGA 775, LGA 1155, LGA 1156, and LGA 1366. The Pentium and Core i7 processors may fit into some of these sockets, but not all four of them.
