A bus is a set of wires or connections that connect the different components together and through which signals travel. there are three major types of buses in computer. in other words, a bus is a set of wires that is used as a communication path. the bus width determines the speed of data transmission.
there are three types of buses in common which are as follows:
there are local buses that connect elements within the CPU and buses, which connect the computer to external memory and peripherals.

The address bus is a collection of wires connecting the CPU with the main memory. it is used to identify particular locations (addresses) in the main memory where data is stored.
The address bus is the connection between the CPU and memory that transmits the address from which the CPU will write. the number of bits in the address bus can determine the amount of memory the CPU can address.
Modern PCs have as many as 36 address lines or buses which enable them theoretically to access 64 GB of main memory. however, the actual amount of memory that can be accessed is usually much less than this theoretical limit due to the chipset and motherboard limitations.
the control bus is a physical connection between the CPU and other devices within the computer.
one line of the bus is used to indicate whether the CPU is currently reading or writing to the main memory.
it is a communication route through which data can travel between the computer’s central processing unit, memory, and peripherals.
the number of wires in the data bus determines the speed at which data can travel between the hardware components, just as the number of lanes on the highway determines the number of vehicles that reach their destinations at the same time.
each wire transmits a single bit at a time, so 8 bits buses can transfer 8 bits at a time. similarly, 16 bits buses can transmit 16-bit simultaneously, and so on.
