asynchronous bus A bus that interconnects devices of a computer system where information transfers between devices are self-timed rather than controlled by a synchronizing clock signal.

What is the difference between asynchronous dram and synchronous dram?

Conventional DRAM, of the type that has been used in PCs since the original IBM PC days, is said to be asynchronous. This refers to the fact that the memory is not synchronized to the system clock. A memory access is begun, and a certain period of time later the memory value appears on the bus. The signals are not coordinated with the system clock at all, as described in the section discussing memory access. Asynchronous memory works fine in lower-speed memory bus systems but is not nearly as suitable for use in high-speed (>66 MHz) memory systems. A newer type of DRAM, called "synchronous DRAM" or "SDRAM", is synchronized to the system clock; all signals are tied to the clock so timing is much tighter and better controlled. This type of memory is much faster than asynchronous DRAM and can be used to improve the performance of the system. It is more suitable to the higher-speed memory systems of the newest PCs.

Describe how the computer bus affects the speed of a computer?

BUS speed is used to define how fast data can be copied from one area of the computer to another. The BUS speed can relate to data being moved between memory and the processor, for example. A processor can process at it's peak speed, but the BUS defines how fast the computer can FEED the processor. Two identical processors, one with a 533 mhz FSB and one with an 800 mhz FSB, the 800 mhx FSB will pass data to the processor faster.

Difference between synchronous bus and asynchronous bus?

1. Syncrhonous bus includes clock in control lines whereas asynchronous bus is not clocked. 2. the devices which need to be connected by synchronous bus should be at same speed whereas an asynchronous bus may connect many devices with varying speeds. 3. A fixed protocol is defined to communicate using synchronous bus which is relative to the clock. An asynchronous bus uses handshaking protocol.


What is the main advantage of the Asynchronous bus over synchronous bus?

As far as I can tell, an asynchronous bus is generally considered slower in performance to a synchronous one. However, it has two useful advantages: * An asynchronous bus allows a device to send or receive data payloads which are of varying sizes. Compare an internal bus, such as PCI, where two devices exchange data in blocks of 32 or 64 bits per clock cycle, and an asynchronous bus, such as USB 2.0, where two devices exchange data packets of up to 1024 bytes. * As it is not bound by a clock cycle, an asynchronous bus allows a relatively slow input/output device to communicate at its own speed - that is, to take its time to find, read and prepare the information it needs to send, or to store the information received and prepare itself for the next incoming portion. When those two are taken into account, an assumption can be made that an asynchronous bus implementation would not require as high precision as a synchronous one to achieve stable, reliable transfers, although I'm not sure if this is actually true. Hope I am correct and this helps.

How can you find out if a bus has arrived?

Contacting the customer care of the Greyhound bus is one of the ways of finding out the timing of the bus. The customer service will be able to provide the correct timing of the bus.


What is asynchronous?

Asynchronous means that data can flow back and forth between 2 things without the transfer being linked to a timer or other method of time synchronization. An example of something that's synchronous is RAM, the system bus and processor send commands at a certain frequency (x commands per second) and the RAM must be synchronized to recieve data at these amount of times per second (frequency), or some kind of multiplier of it or there will be problems reading and writing data to the RAM. Something that is asynchronous does not need to be synchronized to any kind of frequency or clock, it can transmit and recieve data intermittently. Downloading from the internet is asynchronous due to the unreliable nature of TCP/IP over long distances.
