What is a databus as used in computers?
Databus is flow of information called data through a channel. That transportation of information could be serial or parallel. Serial data can be transported basically in two wires circuit, and parallel data is transported through as many wires as its quantity of bits (resolution of the information) Also databus can be in only one direction or both direction.
How many wires of cable cat 6 is use for data?
just one optic cable can carry a lot information to computers
How many wires on a data and address bus?
8
How many wires does a parallel ATA cable have?
A parallel ATA cable has 40 wires. Some high performance cables have 80, but there are only 40 distinct wires - with every other wire being grounded to minimize cross-talk.
How many wires is dedicated to transfer data?
A complete data bus structure is responsible to do this
How many times can a 16 bit bus can transfer ata time?
16-bit bus means the bus has 16 parallel wires for data transfer. That allows it to transfer 16 bits at a time.
A three phrase circuit has how many hot wires?
Three wires carry the three phase energy.
What is the function of a computer ribbon cable?
Ribbon cables in a computer are mostly used for carrying data between devices. Sometimes they are used to carry supply voltages as well, but since they are usually lightweight, they are more commonly used for carrying data and control signals. The most common use is for floppy drives and hard drives. However, they can be used for connecting between different circuit boards, such as a mezzanine card - a type of controller card that has two circuit boards. There were also likely used in older mainframe computers since they contained so many circuit boards. On older Apple computers, they were sometimes used as printer cables too.
How a POT line work?
A POT line (plain old telephone line) is a twisted pair of copper wires that connects a traditional telephone -- aka "landline", aka "hard-wired phone" -- to the telephone company POP building ("point of presence"). Many communication systems, such as some kinds of power-over-Ethernet, use one pair of wires to carry power out, one pair of wires to carry data out, and one pair of wires to carry data in -- 3 separate pairs of wires. The POT system somehow combines all three functions onto a single pair of wires. A POT line uses the "bias-T" technique with a an inductor to combine and split data and power at the ends of the line. (Sometimes a gyrator circuit simulating an inductor is used at the POP end). A POT line uses "echo-cancelling" techniques to combine and split incoming and outgoing data lines at the POP end of the line.
How many wires are there in a USB cable?
a usb cable has four wires, two for power and two for communication.
What is the definition of parallel computing?
The definition of parallel computing is the processing of data many bits at a time as opposed to serial computing which is the processing of data one bit at a time.
IS Keyboard serial or parallel?
As the names imply, a serial port sends data on a small number of wires (often just two wires for the actual data), one bit after the other. A parallel port has many more wires used for data transmission, so many bits can be transmitted simultaneously. The big downside for a serial port is that the "bandwidth" (data bits per second) is very low compared to a parallel port running at the same rate.BUT....parallel data busses have a problem. Electromagnetic interference causes "crosstalk" between the different bits on different data signal lines, and the faster the data rate, the worse the problem gets. Crosstalk causes data transmission errors to occur (a bad thing). So it can actually be a better solution to run a serial data connection at a very, very fast speed than to use a parallel data bus that will have to run at a lower speed (or use more expensive cables and circuitry).In order to do this, each end of the computer bus will use a chip that contains a serial/parallel conversion circuit (SERial/DESerial, or SERDES). This allows the computers to operate on many bits in parallel (byes, words, etc.) but still transmit them in serial over a relatively cheap cable with high data rates.
