What does the Northbridge part of a motherboard control?

PCI, IDE, USB, ISA
CPU, RAM, ROM
AGP, PCIe and Memory
SATA, SCSI, RAID

The correct answer is: AGP, PCIe and Memory

The Northbridge part of a motherboard is responsible for controlling the faster components of a computer system, such as the CPU, RAM, and graphics card. This is why option B is incorrect, as it only includes components that are controlled by the Southbridge part of a motherboard. Option A is also incorrect because these are all peripheral components that are not controlled by the Northbridge. Option D is incorrect because these are all storage-related components. Thus, C is the correct answer as it includes components that are controlled by the Northbridge.
