The external data bus can be as wide as desired, given the necessary compromises between performance, complexity, and cost. The wider the bus, the faster the theoretical aggregate data transfer rate.
In the 8085 and 8088, the external data bus is 8 bits wide; in the 8086, it is 16 bits wide; in the 80386, it is 32 bits wide; and in the modern incarnations of 64 bit processors, it is 64 bits wide.
What else can I help you with?
Communication device of the CPU what is it called?
external data bus
In a Pentium the front side data bus is how many bits wide?
For the Pentium the front side data bus is 64 bits wide. The back side is 32 bits wide.
What is the expansion bus crystal?
It controls the part of the external data bus connected to the expansion slots.
What is an external bus?
In computers, the bus is the subsystem that transfers data between internal parts of the computer, or from internal parts of the computer to external parts, or between two computers. External bus can be parallel (ATA (and all of its derivations), IEEE-488, SCSI) or serial (USB, FireWire, etc.).
The data bus on the Celeron processor is-------bits wide?
64
What is the difference between external data bus and internal data bus?
A data bus connects different parts of a circuit and comprises a group of parallel wires, each one carrying a different logic signal.
What is an address buffer and a data buffer?
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.
Which external bus connector is able to transfer data from device to device?
USB
What is the biggest advantages of 64- bit processor over 32- bit processor?
A 32 bit processor has 32 bit wide data bus while a 64 bit has 64 bit wide data bus. Address bus may or may not be 32 bit or 64 bit wide in the respective processors. To fully utilise the 64 bit data bus the programs must be written in such a way that they can use 64 bit wide data bus. A 64 bit processor can also act as 32 bit.
Which processor had a 32-bit internal bus and a 16-bit external bus?
Which processor has a 32-bit Data Bus and a 24-bit Address Bus?
What is an internal data bus used for?
Internal data bus is defined as a collection or a sequence of the signal line that are responsible for carrying data from one computer to another computer or from one destination to another destination. Basically it is used to transfer data to the external drives and also referred as the internal bus.
How wide is the data bus for a post Pentium CPU?
its 64 bit
