The CPU refers to the "Central Processing Unit". Usually contained on a single chip housed in box popularly referred to as the "Computer". A peripheral is housed external to the computer box. A printer is an example of a peripheral.

A peripheral is anything that digitally communicates with the CPU. This includes everything digital on the motherboard and all the supporting subsystems on the CPU die. BIOS, RAM, North Bridge, South Bridge, L1 Cache, L2 Cache, etc...
A serial bus.

No, peripherals are things like monitors, keyboards, mice etc. CPU is a major component that a computer must have to operate. It is a processor, all other parts are peripherals. (Some computers, some severs for example, do not need any peripherals to operate.)
Bus architecture is the pathway between the CPU and other peripherals. It is usually a shared input/output pathway. Bus is short for omnibus, which means, for all.
The CPU is connected to all the peripherals, which include the keyboard, the monitor, the speakers, and anything else that is connected to your computer. Strictly speaking, the CPU is physically connected to the motherboard.
The function of registers is the same in all computers. They are the fundamental binary interface between the internal and external structure of the CPU. All binary transactions between the CPU and its peripherals pass through registers. From the inside, they are the final periphery to the pins.
Peripherals relative to a motherboard are: power supply unit, CPU, RAM, HDD/SSD, optical drive, graphic/sound/LAN cards (if not integrated).
secret! :p
The difference between a CPU and a GPU is that a CPU stands for central processing unit: (computer science) the part of a computer (a microprocessor chip) that does most of the data processing; "the CPU and the memory from the CPU and the memory form the central part of a computer to which the peripherals are attached". GPU stands for a graphics processing unit (also occasionally called visual processing unit or VPU) is a specialized processor that offloads #D graphics rendering from the microprocessor. It is used in embedded systems, mobile phones, personal computers, workstations, and game consoles.
*data transfer rate of peripherals are slower but faster in the central computer (CPU). *Peripherals uses data codes while CPU uses word format. *Ex: printer, keyboard in Perpherals- Ex: processor, register, ALU unit in Central computer.

The difference between a 32 bit and 64 bit CPU is the speed in which a computer will read and process the information. A 64 bit CPU will read much quicker and can handle the memory usage better than a 32 bit.
