A data bus is simply a communication system that moves data around within a computer. Think of it like an actual public bus system. The data bus "picks up" data that needs to be transferred to some other part of the computer and "drops them off there".

∙ 14y agoLike an information highway, data buses are used to connect to components to allow for high-speed communication and data transferral.
For example, USB (Universal Serial Bus) is the most common external bus, and is used to connect many devices to the computer, and operates at about 480mbit in the case of USb2.0. Other buses, such as AMD's HyperTransport bus operate at 2000 MHz or more, and can transfer 16 GB/s (or 128gbit) and is used to connect the CPU to most other components such as the Northbridge, Southbridge, Videocard, PCI devices, etc.

Difference between data bus and data control 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
What is the purpose of uart?
UART Universal Asynchronous Receiver-Transmitter
What is the io bus controller?
it is used to control the carry the data on bus cable
What are the 3 bus types present in every CPU?
The three types of bus present in every CPU are address bus, data bus and control bus.
What are address bus n data bus?
All computers use three types of basic buses. The name of the bus is generally determined by the type of signal it is carrying or the method of operation. We group the buses into three areas as you see them in their most common uses. They are as follows: Control (also called timing and control bus) bus, Address bus, and data (also called a memory bus) bus. Instruction (I), Operand (O), Input/Output Memory (I/O MEM) or Input/Output Controller (IOC), and Computer Interconnection System (CIS) Time multiplexed bus Control Bus The control bus is used by the CPU to direct and monitor the actions of the other functional areas of the computer. It is used to transmit a variety of individual signals (read, write, interrupt, acknowledge, and so forth) necessary to control and coordinate the operations of the computer. The individual signals transmitted over the control bus and their functions are covered in the appropriate functional area description. Address Bus The address bus consists of all the signals necessary to define any of the possible memory address locations within the computer, or for modular memories any of the possible memory address locations within a module. An address is defined as a label, symbol, or other set of characters used to designate a location or register where information is stored. Before data or instructions can be written into or read from memory by the CPU or I/O sections, an address must be transmitted to memory over the address bus. Data Bus The bidirectional data bus, sometimes called the memory bus, handles the transfer of all data and instructions between functional areas of the computer. The bidirectional data bus can only transmit in one direction at a time. The data bus is used to transfer instructions from memory to the CPU for execution. It carries data (operands) to and from the CPU and memory as required by instruction translation. The data bus is also used to transfer data between memory and the I/O section during input/output operations. The information on the data bus is either written into.
What is the purpose of the address bus?
An address bus carries memory addresses so that Data can be transported and deposited/retrieved from the correct places.
What Are the Types of Buses in a Computer?
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 .
What is the data path beween the microprocessor RAM and the peripherals?
Data bus
Definition of Data Bus?
A communications bus which transfers information or data. Most busses are data busses. This can include the Front Side Bus, PCI bus, Memory Bus, and more.
Difference between data bus and data control 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
Which bus controls the sequencing of read and write operations?
control bus
Is a data bus unidirectional or bidirectional?
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.
What is Buses and what does it do?
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.
What is bidirectional bus?
A bus in this context is a data route which can carry data in both directions.
What is the meaning of the data bus width?
In technology, the bus is used to carry data. The width of a data bus helps determine the amount of bytes that can be carried out each second.
Why data bus is bidirectional bus in Intel 4004?
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.
How do you demultiplex address and data bus?
In order to demultiplex the address and data bus, you provide latches that sample the multiplexed bus. At ALE=true, they follow the bus. At ALE=falling edge, they lock onto the last value of the bus. The latches will then become the address bus, while the original bus becomes the data bus.
