A. B. C. D.C.
The correct answer is B. Frontside bus.
The Frontside bus (FSB) is a communication pathway that connects the processor to other components of the computer system, such as the L2 cache, main memory (RAM), and input/output (I/O) devices. It is responsible for transferring data and instructions between the processor and other system components.
The L2 cache, also known as the secondary cache, is a type of high-speed memory that stores frequently used data and instructions. It is located on the motherboard near the processor, and its purpose is to provide fast access to data that the processor needs to execute instructions. The L2 cache is typically faster than the main memory (RAM) and is used to reduce the time it takes for the processor to access data.
The FSB connects the L2 cache to the processor and enables them to communicate with each other. The FSB is also responsible for coordinating the transfer of data and instructions between the processor and other system components. It is an essential component of the computer system, and its performance can have a significant impact on the overall performance of the system.
The other options, PCI, Backside bus, and System I/O bus, are not directly responsible for connecting the L2 cache to the processor. PCI is a peripheral component interconnect bus used to connect peripheral devices to the computer system. Backside bus connects the processor to the L3 cache, while the System I/O bus connects the processor to the input/output (I/O) devices.
