In a computer, you have a central processing unit, you have memory, you have connections, you have a monitor, and you need a way to get data from one to the other. The thing on your computer that does that job is called a bus. It takes the data in the computer memory and brings it to the CPU or monitor or printer or wherever. (I have no idea why it is called a bus and not a truck!)
The contents of the stack pointer and program counter are loaded into the address buffer and address-data buffer. These buffers are then used to drive the external address bus and address-data bus. As the memory and I/O chips are connected to these buses, the CPU can exchange desired data to the memory and I/O chips. The address-data buffer is not only connected to the external data bus but also to the internal data bus which consists of 8-bits. The address data buffer can both send and receive data from internal data bus.
A 32 bit data bus can send out 4 bytes at a time and can take in 2^32 in addressable memory
A system bus is a single computer bus which historically was used to connect all the major parts of the computer. It combined the jobs of a data bus, address bus, and a control bus. Over the last 30 years, computers have tended to use separate specialized buses instead of a system bus.
A BUS is a wire or group of wires that carry large amounts of data, either serially or in parallel, or a combination of both. I often see it mis-spelled as BUSS. A BUSS is a kiss. The plural of BUS is BUSSES.
Latches in Microprocessor are used for demultiplexing address/data bus.
There are 2 kinds Data bus and address bus data bus which carries the data ( includes both instruction and data). address bus which carries where the data in the data bus must be sent to in the RAM or which I/O device has to be active to read / write data to the data bus .
Data bus
An Address Bus gives the memory instructions on where to place the actual data that it will stored or read. Basically a map location. The Data Bus carries the information that is going to be stored or read using the location that the Address Bus gave to the memory. Address bus is unidirectional while data bus is bi directional
Bus Frequency- (Also Known as Bus Speed) is the rate (or frequency) at which the data on the motherboard is written and read. :)
control bus
In a computer, you have a central processing unit, you have memory, you have connections, you have a monitor, and you need a way to get data from one to the other. The thing on your computer that does that job is called a bus. It takes the data in the computer memory and brings it to the CPU or monitor or printer or wherever. (I have no idea why it is called a bus and not a truck!)
The control bus is a unidirectional bus because it can receive the data from any kind of inputs and send back the output. This whole process is done by the data buses.
Data bus - transfers data round system address bus - CPU provides the addresses to where the data must be fetched, through this bus control bus - timing and signals which control data flow in the system.
Depends on your definition of bus.
A bus in this context is a data route which can carry data in both directions.
A data bus is bidirectional because the processor needs it to both read and write. Also, in the case of the 4004, the data bus was tri-multiplexed with the 12 bit address bus and the 8 bit opcode bus.
