The CPU talks to the RAM via the Front Side Bus (FSB.) The FSB is controlled by the Northbridge processor built into the computer's main board (Motherboard.) The Northbridge also manages your PCI_Express 16x slots, and integrated video cards.

What options have an effect on the speed of the communication between the CPU and RAM in a computer?
CPU front side bus RAM clock rate
How does the system bus contribute to the overall system performance?
Your data busses sends information from component to component i.e. your FSB (front side bus)/system bus/internal bus communicates between your CPU and RAM, the faster it runs, the faster information is moved between your RAM and CPU giving your CPU quicker access to that data.
Why do laptop computers use CPU throttling techniques?
to conserve the battery life by reducing the bus speed between the CPU and RAM
What 4 types of buses are likely to be on a motherboard today?
Address Bus - Transmits memory addresses between the CPU and RAM.Data Bus - The bus that transfers data between CPU and RAM. Expansion Bus - The bus to which add-on adapter cards are connected in order to enhance the functionality on the PC. Video - The bus that transmits display information between the CPU and video circuitry.
What does a CPU bus do?
the CPU bus is the connection between the motherboard and the CPU. All data flows through different data bus.
What chip helps the CPU to work with the RAM?
The northbridge chip. The northbridge connects to the CPU through the front-side bus (FSB) and connects to the RAM through the memory bus.
How is data transferred between a CPU and RAM?
A memory management unit (MMU) is a small device between CPU and RAM recalculating the actual memory address, for example to provide an abstraction of virtual memory or other tasks.
What carries the data and programs that move between the CPU and ram?
In Intel systems- the Front Side Bus In AMD systems- Hyper Transport
What bus does the CPU use to access the system's ram?
Programs from the hard drive are sent to the RAM for quick access and from there are sent to either the CPU or GPU, depending on whether the operation is calculational or some type of video processing.
What is used to connect the CPU directly to RAM?
The central processing unit (CPU) of a computer is interfaced to the random access memory (RAM) via the front side bus (FSB). Additionally the Northbridge is/can also be interfaced with the CPU through FSBs.
VESA and PCI are types of local buses?
A local bus is like a central city bus. Expansion slots gain a direct connection to the CPU as it directly connects to the CPU's own bus. Yes VESA is a local bus , and most probably PCI is also a local bus.
What are differences between a bus and a register that are present in the CPU?
Major difference between Bus and Register is that B for Bus while R for Register
