The wireless data transmission can make full use of the existing network, shorten the construction period, lower construction cost advantages, and equipment installation convenient and simple maintenance. An address bus is a bus that is used to specify a physical address.When a processor or DMA-enabled device needs to read or write to a memory location, it specifies that memory location on the address bus (the value to be read or written is sent on the data bus).The width of the address bus determines the amount of memory a system can address. I/Obuses, which connect the CPU with the systems other components, branch off of the system bus.. This preview shows page 1 - 2 out of 4 pages. It’s main purpose allows the processor to communicate with RAM. In bus characteristics, we had cover the bus width and bus speed, types of buses and bus lines, and also advantages and disadvantages of a “bus” to a “network”. A bus … • Many devices in a system will have their outputs connected to the data bus, but only one device at a time will have its outputs enabled. Retrieved May 27, 2011.
